Recently, the effect of large-scale fires on the global environment has attracted attention. Satellite observation data are used for global estimation of fire CO2 emissions, and available data sources are increasing. Although several CO2 emission inventories have already been released, various remote sensing data were used to create the inventories depend on the studies. We created eight global CO2 emission inventories through fires from 2001 to 2020 by combining input data sources, compared them with previous studies, and evaluated the effect of input sources on CO2 emission estimation. CO2 emissions were estimated using a method that combines the biomass density change (by the repeated fires) with the general burned area approach. The average annual CO2 emissions of the created eight inventories were 8.40 ± 0.70 Pg CO2 year−1 (±1 standard deviation), and the minimum and maximum emissions were 3.60 ± 0.67 and 14.5 ± 0.83 Pg CO2 year−1, respectively, indicating high uncertainty. CO2 Emissions obtained from four previous inventories were within ±1 standard deviation in the eight inventories created in this study. Input datasets, especially biomass density, affected CO2 emission estimation. The global annual CO2 emissions from two biomass maps differed by 60% (Maximum). This study assesses the performance of climate and fire models by revealing the uncertainty of fire emission estimation from the input sources.

Global warming and climate change are the motives to find a solution for emission reduction of diesel engines. Bioethanol is renewable fuel which can be used in diesel engine as a part of biodiesel-diesel blends. The effect of bioethanol on the emission performance of diesel engine for rapeseed biodiesel-diesel blends as a function of engine load is evaluated in this paper. KDE 6500E diesel generator is used for this purpose. Carbon monoxide (CO), unburned hydrocarbons (HC), oxygen (O2) and carbon dioxide (CO2) emissions are recorded with the help of VLT-458 exhaust gas analyzer. Blends with higher concentrations of bioethanol have shown lower CO emissions while HC emissions increase with the increase in bioethanol concentration in the blends. CO2 emissions are recorded more at higher loads for all types of biodiesel and bioethanol concentrations than that of diesel fuel.

Decarbonization of ship power plants and reduction of harmful emissions has become a priority in the technological development of maritime transport, including ships operating in seaports. Engines fueled by diesel without using secondary emission reduction technologies cannot meet MARPOL 73/78 Tier III regulations. The MEPC.203 (62) EEDI directive of the IMO also stipulates a standard for CO2 emissions. This study presents the results of research on ecological parameters when a CAT 3516C diesel engine is replaced by a dual-fuel (diesel-liquefied natural gas) powered Wartsila 9L20DF engine on an existing seaport tugboat. CO2, SO2 and NOx emission reductions were estimated using data from the actual engine load cycle, the fuel consumption of the KLASCO-3 tugboat, and engine-prototype experimental data. Emission analysis was performed to verify the efficiency of the dual-fuel engine in reducing CO2, SO2 and NOx emissions of seaport tugboats. The study found that replacing a diesel engine with a dual-fuel-powered engine led to a reduction in annual emissions of 10% for CO2, 91% for SO2, and 65% for NOx. Based on today’s fuel price market data an economic impact assessment was conducted based on the estimated annual fuel consumption of the existing KLASCO-3 seaport tugboat when a diesel-powered engine is replaced by a dual-fuel (diesel-natural gas)-powered engine. The study showed that a 33% fuel costs savings can be achieved each year. Based on the approved methodology, an ecological impact assessment was conducted for the entire fleet of tugboats operating in the Baltic Sea ports if the fuel type was changed from diesel to natural gas. The results of the assessment showed that replacing diesel fuel with natural gas achieved 78% environmental impact in terms of NOx emissions according to MARPOL 73/78 Tier III regulations. The research concludes that new-generation engines on the market powered by environmentally friendly fuels such as LNG can modernise a large number of existing seaport tugboats, significantly reducing their emissions in ECA regions such as the Baltic Sea.

The blast furnace still dominates the production and supply of metallic units for steelmaking. Coke and coal used in the blast furnace contribute substantially to CO2 emissions from the steel sector. Therefore, blast furnace operators are making great efforts to lower the fossil CO2 emissions and transition to fossil-free steelmaking. In previous studies the use of pre-treated biomass has been indicated to have great potential to significantly lower fossil CO2 emissions. Even negative CO2 emission can be achieved if biomass is used together with carbon capture and storage. Blast furnace conditions will change at substantial inputs of biomass but can be defined through model calculations when using a model calibrated with actual operational data to define the key blast furnace performance parameters. To understand the effect, the modelling results for different biomass cases are evaluated in detail and the overall performance is visualised in Rist- and carbon direct reduction rate (CDRR) diagrams. In this study injection of torrefied biomass or charcoal, top charging of charcoal as well as the use of a combination of both methods are evaluated in model calculations. It was found that significant impact on the blast furnace conditions by the injection of 142 kg/tHM of torrefied biomass could be counteracted by also top-charging 30 kg/tHM of charcoal. With combined use of the latter methods, CO2-emissions can be potentially reduced by up to 34% with moderate change in blast furnace conditions and limited investments.

This paper summarizes the arguments and counterarguments within the scientific discussion on the issue the Management of Environmental Performance and the Carbon Dioxide Emissions (CO2) on the Economic Growth, with an innovative study in the context of the GCC countries. The main goal of the paper is to examine empirically the environmental Kuznets curve hypothesis for the GCC countries. The methodological tool of this contribution tries to measure the effect of the emission of the CO2 on the Growth Economic and environmental performance. The main purpose of the research is focused on the empirical approach justified by the use of a dynamic panel modeling on a sample of the GCC countries during the period of 2002-2018. Systematization literary sources and approaches for solving the problem of the reaction of the development of the Environmental Performance with the level of the the Carbon Dioxide Emissions (CO2) and the economic growth. The study employed a GMM model system. Subsequently, the authors displayed a Panel Co-integration test of Pedroni (2004), the Kao Residual Co-integration test (1999), and the Granger causality tests. The results found unidirectional causal relationships between economic growth and the entire variable of the sample, except the variable CO2 emission. These relationships are statistically significant at the level of 5%. For the relation between Economic Growth and CO2 emission, one the hypothesis of the paper was checking a non-significant and unidirectional relationship. The results showed a long-run unidirectional causality between the variables and implied that Economic Growth in the GCC countries has a positive and significant unidirectional relation with Environment Performance, trade openness, foreign direct investment, and investment. The results confirm the existence of a negative relationship as insignificant, and unidirectional, between economic growth and CO2 emissions in the GCC countries. Finally, this finding doesn’t support the validity of the EKC hypothesis and provide information's to take the necessary policy suggestions to maintain the environmental performance and limit the average of the CO2 emissions. The results of the research can be useful for the GCC countries to avoid the higher level of Carbon Dioxide Emissions (CO2) and maintain a good Environmental Performance. Keywords: environmental performance, Environmental Kuznets Curve, CO2 emissions.

The objective of this paper was to quantify the economic and environmental effects of changing a dairy farm’s milking start times. Changing morning and evening milking start times could reduce both electricity costs and farm electricity related CO2 emissions. However, this may also involve altering farmer routines which are based on practical considerations. Hence, these changes need to be quantified both in terms of profit/emissions and in terms of how far these milking start times deviate from normal operations. The method presented in this paper optimized the combination of dairy farm infrastructure setup and morning and evening milking start times, based on a weighting variable (α) which assigned relative importance to labor utilization, farm net profit and farm electricity related CO2 emissions. Multi-objective optimization was utilized to assess trade-offs between labor utilization and net profit, as well as labor utilization and electricity related CO2 emissions. For a case study involving a 195 cow Irish dairy farm, when the relative importance of maximizing farm net profit or minimizing farm electricity related CO2 emissions was high, the least common milking start times (06:00 and 20:00) were selected. When the relative importance of labor utilization was high, the most common milking start times (07:00 and 17:00) were selected. The 195 cow farm saved €137 per annum when milking start times were changed from the most common to the least common. Reductions in electricity related CO2 emissions were also seen when the milking start times were changed from most common to least common. However, this reduction in emissions was primarily due to the addition of efficient and renewable technology to the farm. It was deduced that the monetary and environmental benefits of altering farmer milking routines were unlikely to change normal farm operating procedures.

Carbon emissions from China’s electricity sector account for about one-seventh of the global carbon dioxide emissions, or half of China’s carbon dioxide emissions. A better understanding of the relationship between CO2 emissions and electric output would help develop and adjust carbon emission mitigation strategies for China’s electricity sector. Thus, we applied the electricity elasticity of carbon emissions to a decoupling index that we combined with advanced multilevel Logarithmic Mean Divisia Index tools in order to test the carbon emission response to the electric output and the main drivers. Then, we proposed a comparative decoupling stability analysis method. The results show that the electric output effect played the most significant role in increasing CO2 emissions from China’s electric sector. Also, “relative decoupling” was the main state during the study period (1991–2012). Moreover, the electricity elasticity of CO2 emissions had a better performance regarding stability in the analysis of China’s electricity output.

The environmental performance index was developed to protect public health, and to sustain and manage the ecological vitality that is a crucial factor in countries’ social and economic development. The increase in CO2 emissions has been threatening environmental and human health. The main objective of this study is to evaluate the impact of economic growth, energy consumption, energy management, the urban population, trade openness, and financial development on CO2 emissions in the OECD countries that have a high ranking in the environmental performance index by utilizing the panel data analysis method for the years spanning 1990–2014. This assessment finds positive relationships between economic growth, energy consumption, and the urban population, and CO2 emissions. Moreover, it is put forward that a negative and significant relationship between financial development and CO2 emissions exists. Despite displaying a similar negative correlation, the relationship between trade openness and CO2 emissions is insignificant. In the Dumitrescu-Hurlin panel causality test conducted, it was seen that a two-way causality is prevalent between energy consumption and CO2 emissions. In addition, interrelations where CO2 emissions cause trade openness, and the urban population is an explanatory variable of the former relationship, were discovered.

In recent years, Guangdong has achieved remarkable performance in economic development; meanwhile it is being faced with problems of increasing CO2 emissions. Following the IPCC Guidelines for National Greenhouse Gas Inventories, we estimated the energy-related CO2 emissions in Guangdong during the period of 1980-2010. We employed the logarithmic mean divisia index (LMDI) method to decompose the CO2 emissions into energy intensity, energy structure, per capita GDP and population scale effects. Besides, we deduced the calculation methods for the year by year effects, the accumulated effects and the contribution degrees. Using 1980 as the base year, the empirical results show that the accumulated effects of energy intensity and energy structure in 2010 are negative, while those of per capita GDP and population scale are positive. Per capita GDP is the chief positive influence on the CO2 emissions. Energy intensity is becoming more significant; however, its direction is instability. Population scale has a significant positive effect on the CO2 emissions. Energy structure has a negligible negative impact on the CO2 emissions. Some suggestions on CO2 emissions reduction in Guangdong are given based on the analysis.

Abstract. In recent years evidence has emerged that the amount of isoprene emitted from a leaf is affected by the CO2 growth environment. Many – though not all – laboratory experiments indicate that emissions increase significantly at below-ambient CO2 concentrations and decrease when concentrations are raised to above ambient levels. A small number of process-based leaf isoprene emission models can reproduce this CO2-stimulation and -inhibition. These models are briefly reviewed, and their performance in standard conditions compared with each other and to an empirical algorithm. One of the models was judged particularly useful to be incorporated into a dynamic vegetation model framework, LPJ-GUESS, aiming to develop a tool that allows the interactive effects of climate and increasing CO2 concentration on vegetation distribution, productivity, and leaf and ecosystem isoprene emissions to be explored. The coupled vegetation dynamics-isoprene model is described and used here in a mode particularly suited for the ecosystem scale, but it can be employed at the global level as well. Annual and/or daily isoprene emissions simulated by the model were evaluated against flux measurements (or model estimates that had previously been evaluated with flux data) from a wide range of environments, and agreement between modelled and simulated values was generally good. By using a dynamic vegetation model, effects of canopy composition, disturbance history, or trends in CO2 concentration can be assessed. We show here for five model test sites that the suggested CO2-inhibition of leaf-isoprene metabolism can be large enough to offset increases in emissions due to CO2-stimulation of vegetation productivity and leaf area growth. When effects of climate change are considered atop the effects of atmospheric composition the interactions between the relevant processes will become even more complex. The CO2-isoprene inhibition may have the potential to significantly dampen the expected steep increase of ecosystem isoprene emission in a future warmer atmosphere with higher CO2 levels; this effect raises important questions for projections of future atmospheric chemistry and its connection to the terrestrial vegetation and carbon cycle.

Sustainability and finance should go hand in hand. A financial system that supports sustainablegrowth is necessary for the transition to a carbon-free society. Environmental, Social andGovernance (ESG) is a sustainability performance measurement used worldwide. Previousresearch within the ESG area has mainly focused on ESG score and financial performance.Environmental performance gets more attention from investors, and the Nordic countries areall in the top five when it comes to sustainability ranking. This research examines the relationbetween sustainability ratings (E score and ESG score) in the Nordic countries as well as if therelation differs between different rating agencies. To study the relationships, a regressionanalysis was performed, and we could not draw any concrete conclusions whether low CO2emissions are associated with a higher E- or ESG score in the Nordic countries. The resultindicates that a high E- or ESG score does not seem to be associated with lower CO2 emissions.A significant result was found on the fact that the E- and ESG scores relation to CO2 aredifferent between rating agencies. However, full access to one of the rating agencies has notbeen granted, which entails some limitations and further research on the questions isrecommended.

In assessing the impact of global tourism on climate change, emissions from transport receive the most attention although emissions associated with accommodation account for more than 20% of the total. A plethora of hotel certification schemes have been established worldwide that assess various environmental performance indicators, among them energy use. However, none explicitly quantify CO2 emissions, and in many, energy is poorly accounted for, or other non-energy related factors are weighted so that the overall impact of energy use (and hence CO2 emission) is weak. The main thrust of the research is to ascertain the effect of certification on CO2 emissions. The research questions whether the certification schemes are robust and rigorous and whether the results are credible. First, four widely used certification schemes are compared Nordic Swan (Scandinavia), Green Globe (Worldwide), EU Flower (European) and Green Hospitality Award (Ireland). The key issues are identified such as performance and process related criteria, use of benchmarks, and the weighting of different categories. A comparison is made with LEED-EB, a well-established environmental certification scheme, not dedicated to the hotel sector. Secondly, the way in which emissions from electricity, including so-called green electricity and carbon offsetting, are accounted for is examined since it is found that in obtaining certification, this often plays an important part. Actual annual energy use data is desperately needed as feedback to designers, managers and owners in order to give confidence that certification schemes have true validity. Results are presented from large multi-hotel data samples and for detailed results from the quality, illustrative in-depth studies which provided invaluable insight into the technical realities of a multitude of causes and effects which can often be masked in large data samples. An analysis was carried out for four In-depth studies located in Sweden (Nordic Swan), Maldives (Green Globe), Malta (EU Flower) and Ireland (Green Hospitality Award). Global CO2 emissions were compared and calculated from the delivered electricity and fuels consumption data from seventy selected certified hotels worldwide. No corrections were made in the calculations for climate, quality of services, existence of services etc. The performance indicator used is kgCO2 per guest night. The analyses shows no clear pattern. CO2 emissions show a wide variance in performance for 8 hotels certified under different schemes, as well as for 28 hotels certified under the same scheme. In some cases emissions reduced after certification in others no change. Certified hotels do not necessarily have lower emissions than uncertified hotels and a comparison of before – and after – certification shows no significant improvement prior to certification. Most dramatically emissions from certified hotels widely vary by a factor of 7. Although it is arguable a number of corrections should be made to account for different climates, the research highlights that hotels with high CO2 emissions are being awarded certification and it questions what message‘certification’ gives to guests and other stakeholders. At worst it appears ‘business as usual’ can achieve certification with no obvious improvement in performance. The overall conclusion is that existing certification schemes do not properly account for CO2 emissions and do not produce more energy efficient (or less CO2 intensive) buildings. Hotel accommodation was found to be more CO2 intensive than domestic emissions. The findings also uncovered inconsistencies in current methods of certification and indicate a vital need for improved methods. The results also challenge prevailing aesthetic stereotypes of sustainable hotels. The author concludes a simple CO2 accounting method is needed as the first step of a diagnostic process leading to a solution i.e. reduced emissions, to the problem i.e. high energy consumption and/or emissions, thus reducing the environmental impact (in terms of emissions reduction) of the hotel. This method of accounting can be adopted universally by using a Regional, European (O.475 kgCO2/kWh) or Universal (0.55 kgCO2/kWh) conversion factor. In relation to the proper calculation of energy and CO2 emission, sub-metering is a key factor, and with current technological developments, realistic and affordable. Furthermore, apart from certification itself, an essential quality with any monitoring system is that the user can obtain results easily and understandably, in order to get feedback from their actions. This could be facilitated by incorporating sub-metering as part of the building environmental management system software. This ensures that the certification activity is not simply a benchmark, but is also part of a diagnostic and educational process, which will continue to drive emissions down. Only then should it be ethically justified to use as a marketing tool providing diagnostic support in existing buildings, and design and operational guidance for new designs.

The study analyses the calibration process of a newly developed high-performance plug-in hybrid electric passenger car powertrain. The complexity of modern powertrains and the more and more restrictive regulations regarding pollutant emissions are the primary challenges for the calibration of a vehicle’s powertrain. In addition, the managers of OEM need to know as earlier as possible if the vehicle under development will meet the target technical features (emission included). This leads to the necessity for advanced calibration methodologies, in order to keep the development of the powertrain robust, time and cost effective. The suggested solution is the virtual calibration, that allows the tuning of control functions of a powertrain before having it built. The aim of this study is to calibrate virtually the hybrid control unit functions in order to optimize the pollutant emissions and the fuel consumption. Starting from the model of the conventional vehicle, the powertrain is then hybridized and integrated with emissions and aftertreatments models. After its validation, the hybrid control unit strategies are optimized using the Model-in-the-Loop testing methodology. The calibration activities will proceed thanks to the implementation of a Hardware-in-the-Loop environment, that will allow to test and calibrate the Engine and Transmission control units effectively, besides in a time and cost saving manner.

Els gasos amb efecte d'hivernacle (GEH) procedents de l'agricultura depenen de la gestió del reg i dels fertilitzants. L'objectiu d'aquesta tesi va ser identificar les principals estratègies per a mitigar els GEH i obtenir un rendiment màxim: (i) reg continu (CI)/intermitent (II) en un camp d'arròs; (ii) fertilització de fons amb gallinassa (CM), purí porcí (PS), urea (U) o sulfat d'amoni (AS) en un camp d'arròs; (iii) incorporació/eliminació de rostoll de panís amb diferents dosis de N mineral, i (iv) reg enterrat (SDI)/superficial por degoteig (DI) combinat amb N mineral aplicat via fertirrigació amb i sense DMPP en un cultiu súper-intensiu d'olivera. El reg continu minimitza significativament les emissions dels camps d'arròs al mateix temps que garanteix un alt rendiment. L'aplicació de purí porcí en dosis agronòmiques determina alts rendiments i minimitza els GEH. Respecte als GEH i al rendiment del panís, el tractament control va ser la millor opció, independentment de la gestió del rostoll. Així mateix, l'aplicació de DMPP + 50 kg N ha-1 + reg superficial per degoteig (DI) va ser la millor opció pel cultiu d'olivera súper-intensiva
Los emisión de gases con efecto invernadero (GEI) procedentes de la agricultura depende de la gestión del riego y de los fertilizantes. El objetivo de esta tesis fue identificar las mejores estrategias -de entre las siguientes- para mitigar los GEI manteniendo un rendimiento máximo: (i) riego continuo (CI)/intermitente (II) en un arrozal, (ii) la fertilización de fondo con gallinaza (CM) , purín porcino (PS), urea (U) o sulfato amónico (AS) en un arrozal con AS en cobertera, (iii) la incorporación/eliminación del rastrojo con diferentes dosis de N mineral en el cultivo del maíz, (iv) el riego por goteo enterrado (SDI)/superficial (DI) en combinación con N mineral aplicado vía fertirrigación con y sin DMPP en un olivar súper-intensivo. El CI mitiga significativamente las emisiones del arrozal al tiempo que garantiza el rendimiento máximo. La aplicación de purín porcino a dosis agronómicas proporciona altos rendimientos y minimiza los GEI. Considerando las emisiones de GEI y el rendimiento del maíz, el tratamiento control fue la mejor opción, independientemente de la gestión del rastrojo. La aplicación de DMPP + 50 kg N ha-1 + DI fue la mejor opción para el cultivo súper-intensivo de olivo.
Greenhouse gases emissions from agriculture depend on irrigation and fertilisation management. The objective of this thesis was to identify the less emitting management strategies among the following, compatible with a feasible yield: (i) continuous (CI)/intermittent irrigation (II) on rice, (ii) background fertilization with chicken manure (CM), pig slurry (PS), urea (U) or ammonium sulphate (AS) and topdressing on rice, (iii) stover incorporation/removal with different doses of mineral N and, (iv) subsurface (SDI)/surface drip irrigation (DI) in combination with mineral N fertigation with and without DMPP on a super-intensive olive tree orchard. Continuous irrigation significantly mitigated emissions from paddy fields while ensuring the highest yield. Pig slurry application at agronomic doses allowed high yields and minimized emissions. Based on emissions and maize yield, the control treatment was the best option regardless of stover management. Applying DMPP with 50 kg N ha-1+ drip irrigation (DI) was the best option for the olive tree orchard.

Growing pressure on the packaging design to enhance the environmental and logistics performance of a packaging system stresses the packaging designers to search new design strategies that not only fulfill logistics requirements in the supply chain, but also reduce the CO 2emissions during the packaging life cycle. This thesis focuses on the packaging design process and suggests some improvements by considering its logistics performance and CO 2emissions. A Green packaging development model was proposed for corrugated box design to explore the inter-dependencies that exist among compressive strength, waste and CO2emissions. The verification of the proposed model unveils the significance of a holistic view of the packaging system in the packaging design process and reveals the importance of packaging design decisions on the logistics performance and CO 2 emissions. The thesis finally concluded that the packaging logistics performance should be considered in a packaging design process to explore the Green packaging design solution.

As the world battles with the triple problems of social, economic, and environmental challenges, it has become important to focus both policy and research efforts on these. Therefore, this study examines the effect of wealth inequality on CO2 emissions in five emerging economies: Brazil, Russia, India, China, and South Africa. The top decile of wealth share was used as a measure of wealth inequality, while CO2 emissions per capita were used as a measure of CO2 emissions. GDP per capita, population, and financial development (domestic credit to the private sector) were included as control variables. A balanced panel dataset of annual observations from 2000 to 2014 for these countries was used. Both fixed and random effects panel models were estimated, but the Hausman test favoured the use of the fixed effects model. The results based on the fixed effects panel regression model show that wealth inequality, GDP per capita, and population have positive effects on CO2 emissions, while financial development has a negative effect.

AbstractThere are severe environmental and ecological issues once we evaluate the architecture industry with LCA (Life Cycle Assessment), such as emission of CO2 caused by necessary high temperature for producing cement and significant amounts of Construction Demolition Waste (CDW) in deteriorated and obsolete buildings. One of the ways to solve these problems is Bio-Material. CELLULOSE and CHITON is the 1st and 2nd abundant substance in nature (Duro-Royo, J.: Aguahoja_Programmable Water-based Biocomposites for Digital Design and Fabrication across Scales. MIT, pp. 1–3 (2019)), which means significantly potential for architectural dimension production. Meanwhile, renewability and biodegradability make it more conducive to the current problem of construction pollution. The purpose of this study is to explore Cellulose Based Biomaterial and bring it into architectural scale additive manufacture that engages with performance in the material development, with respect to time of solidification and control of shrinkage, as well as offering mechanical strength. At present, the experiments have proved the possibility of developing a cellulose-chitosan- based composite into 3D-Printing Construction Material (Sanandiya, N.D., Vijay, Y., Dimopoulou, M., Dritsas, S., Fernandez, J.G.: Large-scale additive manufacturing with bioinspired cellulosic materials. Sci. Rep. 8(1), 1–5 (2018)). Moreover, The research shows that the characteristics (Such as waterproof, bending, compression, tensile, transparency) of the composite can be enhanced by different additives (such as xanthan gum, paper fiber, flour), which means it can be customized into various architectural components based on Performance Directional Optimization. This solution has a positive effect on environmental impact reduction and is of great significance in putting the architectural construction industry into a more environment-friendly and smart state.

Abstract The purpose of this chapter is to investigate the effects of some mainstream policy schemes in the power sector on the reduction of CO2 emissions. The first part of this chapter is the analysis on the effects of promoting generation (fuel) efficiency of fossil-fuel power generation, specifically assuming more efficient coal-fired power plants that recently indicates increased presence in the Japanese power sector. Improvement in generation efficiency of fossil-fuel power plants is expected to reduce emissions of carbon dioxide mainly from a technological aspect. However, overall effects on carbon reduction in the whole industry would be ambiguous since it also depends on market structure. The increased efficiency in generation leads to an improvement in cost conditions of fossil-fuel power producers relative to their rivals. It enables them to expand their generation and market share. Analyzing the Cournot oligopoly model, it is shown that an improvement in fossil-fuel power generations produces two effects: the ‘saving effect’ and the ‘rebound effect’. The total CO2 emission in the whole industry decrease if the former effect exceeds the other, and vice versa. In addition, it is indicated that a rise in the generation efficiency would increase a difficulty of implementing carbon tax. In the second part of this chapter, I study the combination of feed-in tariff and carbon tax; that would be worthy to investigate since they could possibly complement each other. FIT policy could be financed by the revenue of carbon tax, and a reduction in electricity supply by the carbon tax would be lessen by supporting renewable power generations under FIT. It is demonstrated that FIT had the combined effects: it fosters a competitive environment in addition to indirectly reduces CO2 emissions. The result indicates that the combination of these policies would produce potential welfare gains.

The aim of this study is to examine on the relationship between economic growth and environmental performance in the 28 Bulgarian districts for the period between 2010 and 2016. The results show that when in the cases where CO2 emissions are medium, the relationship with the economic growth is very weak. However, for those districts with higher CO2 emissions per capita there is a significant relation with the economic variables. This would mean that economic growth would have a strong effect on the air quality only after certain amount of CO2 emissions.

In a carbon constrained world there is a need for capturing and sequestering CO2. Post-combustion carbon capture via Exhaust Gas Recirculation (EGR) is considered a feasible means of reducing emission of CO2 from power plants. Exhaust Gas Recirculation is an enabling technology for increasing the CO2 concentration within the gas turbine cycle and allow the decrease of the size of the separation plant, which in turn will enable a significant reduction in CO2 capture cost. This paper describes the experimental work performed to better understand the risks of utilizing EGR in combustors employing dry low emissions (DLE) technologies. A rig was built for exploring the capability of premixers to operate in low O2 environment, and a series of experiments in a visually accessible test rig was performed at representative aeroderivative gas turbine pressures and temperatures. Experimental results include the effect of applying EGR on operability, efficiency and emissions performance under conditions of up to 40% EGR. Findings confirm the viability of EGR for enhanced CO2 capture; In addition, we confirm benefits of NOx reduction while complying with CO emissions in DLE combustors under low oxygen content oxidizer.

Gaseous fuels such as landfill gas contain significant quantities of inerts, typically CO2 and N2. This can lead to difficulties in predicting the emission and thermodynamic performance of industrial gas turbines. An algorithm has been developed to predict emissions of NOx for known quantities of inerts and effects on performance quantified. The effect of steam injection is compared to that of inerts and a relationship established.

Future energy systems based on solid fuel gasification for co-production of power and fuels may require gas turbine operation on unusual gas fuel mixtures. In addition, global climate change concerns may dictate the production of a CO2 product stream for end-use or sequestration, with potential impacts on the oxidizer used in the gas turbine. In this study the operation at atmospheric pressure of a small, optically accessible swirl-stabilized premixed combustor is investigated when burning fuels ranging from pure methane to shifted or filtered syngas mixtures. Both air and CO2-diluted oxygen are used as oxidizers. CO and NOx emissions for these flames have been determined over the full operation range from lean blowout to slightly rich conditions. In practice, CO2-diluted oxygen systems will likely be operated close to stoichiometric conditions to minimize oxygen consumption. The presence of hydrogen in the syngas fuel mixtures results in compact, high temperature flames, resulting in increased flame stability and higher NOx emissions. The lean blowout limit decreases with increasing H2 content in the syngas. Similarly, CO emissions for lean stoichiometries decrease with increasing H2 content. CO emissions near the stoichiometric combustion point do not become significant until φ > 0.95, at which point CO emissions rise more rapidly for combustion in O2-CO2 mixtures than for combustion in air.

A reliable prediction of attainable ship speed at actual seas is essential from economical and environmental aspects. At this paper a methodology for estimating the attainable speed and related fuel consumption and carbon dioxide (CO2) emissions in moderate and severe sea is proposed. The irregular sea is handled as a series of regular waves with different amplitudes and frequencies. The added resistance in regular waves is obtained by either a direct pressure integration method or an asymptotic small wavelength formula. The in-and-out-of-water-effect and ventilation of a propeller in severe seas is accounted for by a quasi-steady averaging of experimental data for different propeller submergences. The propulsion results for regular waves are used in simulating results in irregular waves. It is shown that for higher sea states this effect has much more influence on the speed loss than the added resistance in waves. The speed loss is calculated by taking into account the engine and propeller performance in actual seas as well as the mass inertia of the ship. The numerical model used for main propulsion engine modeling is based on a zero-dimensional model of an internal combustion engine. The main propulsion engine is represented by number of control volumes interconnected with links for mass and energy transfer between them. This model provides excellent prediction of engine dynamic response during transients with rather short computational time. Also, engine fuel consumption can be precisely determined which represents the basic presumption for estimation of carbon-dioxide emission. Furthermore, use of such model can be extended to determination of the lowest fuel oil consumption strategy for given sea condition and ship speed with resulting lowest possible CO2 emissions. The attainable ship speed is obtained as time series. Correlation of speed loss with sea states allows predictions of propulsive performance in actual seas.

The aim of this study is to investigate the suitability of landfill gas (LFG) as an alternative fuel for an internal combustion (IC) engine and how to reduce pollutants emissions from LFG operations by adding syngas to LFG. The effect of CO2 fractions in LFG on the engine performance and exhaust emissions such as CO, UHC and NOx are experimentally determined, and a simulated LFG (50% CH4 and 50% CO2) mixed with a simulated syngas consisting of H2 and CO (H2/CO = 2) is also studied. The Honda GC160E engine connected with a small generator which functions as different electrical loads is used for this study. When CO2 fraction in LFG changes from 0% to 50% at 0.8 kW load condition, CO and UHC emissions increase from 241.8ppm to 802.1ppm and from 35.6ppm to 113.4ppm respectively, while NOx emission decreases from 126.7ppm to 99.8ppm. In case of LFG (50% CH4 and 50% CO2)-syngas (H2/CO = 2) mixtures, 5% addition of syngas to LFG at 0.8 kW load condition reduces CO, UHC and NOx emissions from 802.1ppm to 203.1ppm, from 113.4ppm to 11.1ppm and from 99.8ppm to 64.5ppm, respectively. However, when more syngas is added to LFG (10% and 15% syngas in fuel mixture) it does not measurably reduce these emissions any further.

There exists an important awareness for reduction of CO2 emissions to obtain a sustainable world. Together with this, there is a great deal of interest for decomposition analysis to see the accelerating and decelerating factors of CO2 emissions. The aim of this project is to decompose CO2 emissions in economic sectors for the two superpowers of Middle East, Iran and Turkey, over the time period between 1990 and 2010, for Turkey obtained a rapid growth performance in recent years and Iran which is the energy superpower of the world. Refined Laspeyres Index decomposition method and a consistent data gathered from the World Bank’s and UN’s databases have been used during the analysis. Five main sectors (agriculture, manufacturing, transportation, construction and other service sectors) and four main impacts (scale effect, composition effect, energy intensity effect and carbon intensity effect) have been considered to see the increasing and decreasing factors of CO2 emissions. Various interesting results are observed for both of the countries, for each of the economic sectors. Generally scale effect and energy intensity effect are the dominant impacts for all sectors of both countries. However composition effect and carbon intensity effect are also important contributors for economic activities of these two countries. Overall, our analysis showed that these two countries should pay attention for energy intensity and sustainable economic growth.

Coal consumption for electricity generation produces over 30% of U.S. carbon dioxide (CO2) emissions, but coal is also an available, secure, and low cost fuel that is currently utilized to meet roughly half of America’s electricity demand. While the world transitions from the existing fossil fuel-based energy infrastructure to a sustainable energy system, carbon dioxide capture and sequestration (CCS) will be a critical technology that will allow continued use of coal in an environmentally acceptable manner. Techno-economic analyses are useful in understanding the costs and benefits of CCS. However, typical techno-economic analyses of post-combustion CO2 capture systems assume continuous operation at a high CO2 removal, which could use 30% of pre-capture electricity output and require new capacity installation to replace the output lost to CO2 capture energy requirements. This study, however, considers the inherent flexibility in post-combustion CO2 capture systems by modeling power plants that vary CO2 capture energy requirements in order to increase electricity output when economical under electricity market conditions. A first-order model of electricity dispatch and a competitive electricity market is used to investigate flexible CO2 capture in response to hourly electricity demand variations. The Electric Reliability Council of Texas (ERCOT) electric grid is used as a case study to compare plant and grid performance, economics, and CO2 emissions in scenarios without CO2 capture to those with flexible or inflexible CO2 capture systems. Flexible CO2 capture systems can choose how much CO2 to capture based on the competition between CO2 and electricity prices and a desire to either minimize operating costs or maximize operating profits. Coal and natural gas prices have varying degrees of predictability and volatility, and the relative prices of these fuels have a major impact on power plant operating costs and the resulting plant dispatch sequence. Because the chosen operating point in a flexible CO2 capture system affects net power plant efficiency, fuel prices also influence which CO2 capture operating point may be the most economical and the resulting dispatch of power plants with CO2 capture. Several coal and natural gas price combinations are investigated to determine their impact on flexible CO2 capture operation and the resulting economic and environmental impacts at the power plant and electric grid levels. This study investigates the costs and benefits of flexible CO2 capture in a framework of a carbon-constrained future where the effects of major energy infrastructure changes on fuel prices are not entirely clear.

Syngas is composed of mixtures of H2 and CO and inerts such as N2, steam and CO2. The composition of syngas derived from oxygen and air-blown gasifiers is discussed. The low exhaust gaseous emissions potential of diffusion, lean premixed and rich catalytic combustors with representative oxygen and air-blown syngas fuels are evaluated. The evaluation is performed using network of well-stirred reactor models. The parameters of the reactor models are carefully chosen so as to represent the flow-physics in the combustors. Predictions of NO and CO emissions for the different combustion modes are presented for the representative syngas fuels. The calculations are performed with combustor pressures and inlet temperatures typical of heavy-duty gas turbine power generation plants. The effect of combustor exit temperature, added diluents and the composition of the fuel on NO and CO emissions are evaluated for the different combustion technologies. The sensitivity of the emissions to reactor parameters is also explored.
