Purpose Recent developments in the electricity generation sector of Nigeria necessitated the re-assessment of its contribution to air emission level in the country as information provided by previous inventory is nearly out-of-date. The purpose of this paper is to quantify the carbon dioxide (CO2) emissions generated from existing thermal power plants in the country. Design/methodology/approach Thermal power plants in Nigeria and their installed capacities were identified, and estimation of CO2 emission from each of the plants was carried out using the emission factor method. In addition to the direct emissions generated through the combustion operation of the power plants, indirect emissions resulting from upstream activities such as extraction, production, and transportation of fuels consumed by the thermal power plant was determined using the same method. Findings In total, 40 thermal power plants are currently operational in Nigeria. Additional 18 thermal plants are at different stages of completion. The operational thermal plants have average generation output of 40 percent of their installed capacity and produce 87.3 million metric tonne (mmt)/annum CO2 emissions. In total, 66.9 percent of the estimated emissions are direct emissions, i.e. fuel combustion emissions; the rest are indirect emissions. Additional 67.9 mmt was estimated as expected overall emissions from the thermal power plants under construction. Considering the global warming potential of CO2, proactive measures must be taken to regulate its emissions from the country’s thermal power plants. Originality/value This paper bridged the information gap existing in the emission inventory from the Nigeria electricity sector by providing up-to-date data on the contribution of the sector to greenhouse gas emission level in the country.

The implementation of cutting-edge agricultural practices provides tools and techniques to drive climate-smart agriculture, reduce carbon emissions, and lower the carbon footprint. The alteration of climate conditions due to human activities poses a serious threat to the global agricultural systems. Greenhouse gas emissions (GHG) from organic waste management need urgent attention to optimize conventional composting strategies for organic wastes. The addition of various inorganic materials such as sawdust and fly ash mitigate GHG during the vermicomposting process. This paper critically investigates the factors responsible for GHG emissions during vermicomposting so that possible threats can be managed.

Mankind’s rapidly increasing advancements in different industrial sectors demand a great price of environmental impact and climate change in return, specifically in the buildings and construction industry. The largest source of greenhouse gas emissions and energy consumption worldwide are buildings, estimated to account for almost 48% of all such emissions. Energy-related Carbon Dioxide (CO2) counts for about 82% of all greenhouse gases emitted by human activities. This total energy consumption translates to approximately 3.5 Billion Euros per annum. According to a report from the United Nations Environment Programme, the right mix of appropriate government regulations, greater use of energy-saving technologies and user behavioural changes can substantially reduce CO2 emissions from buildings. The Energy Performance of Buildings Directive places an onus on all EU member states to rate the energy performance of buildings in a Building Energy Rating certificate which is effectively an energy label required at the point of rental ...

Full textAbstract:
Earthwork, an essential activity in most construction projects, consumes large quantities of fossil fuel and produces substantial air pollution with adverse environmental impacts. To achieve more sustainable construction processes, novel methodologies to evaluate and improve the performance of earthwork operations are required. This study quantifies the real-world emissions and fuel consumption of construction equipment within an earthwork project in China. Two wheel loaders and two dump trucks are examined through on-board measurements and in-lab engine tests. The duty cycles of construction equipment are categorized with respect to their power efficiency and working patterns. Moreover, the power-specific and time-based emission factors for these duty cycles are computed and compared with relevant legislative emission limits. Significant emission variations among different duty cycles were found, and the real-world emission measurements exceeded the results from the in-lab test required for emission certification. In addition, a discrete-event simulation (DES) framework was developed, validated, and integrated with the computed emission factors to analyze the environmental and energy impacts of the earthwork project. Furthermore, the equipment fleet schedule was optimized in the DES framework to reduce greenhouse gas emissions and fuel consumption by 8.1% and 6.6%, respectively.

Full textAbstract:
Salt-affected soils contain high levels of soluble salts (saline soil) and exchangeable sodium (alkali soil). Globally, about 932 million ha (Mha), including 831 Mha of agricultural land, is salt-affected. Salinity and sodicity adversely affect soil microbial diversity and enzymatic activities, and thereby carbon and nitrogen dynamics and greenhouse gas (GHG) emissions from soils. In this review article, we synthesize published information to understand the impact of salinity and sodicity on GHG production and emissions from salt-affected soils, and how various reclamation amendments (gypsum, phosphogypsum, organic manure, biochar, etc.) affect GHG emissions from reclaimed soils. Nitrous oxide (N2O) and methane (CH4) emissions are of greater concern due to their 298 and 28 times higher global warming potential, respectively, compared to carbon dioxide (CO2), on a 100-year time scale. Therefore, CO2 emissions are given negligible/smaller significance compared to the other two. Generally, nitrous oxide (N2O) emissions are higher at lower salinity and reduced at higher salinity mainly due to: (a) higher ammonification and lower nitrification resulting in a reduced substrate for denitrification; (b) reduced diversity of denitrifying bacteria lowered down microbial-mediated denitrification process; and (c) dissimilatory nitrate reduction to ammonium (DNRA), and denitrification processes compete with each other for common substrate/nitrate. Overall, methane (CH4) emissions from normal soils are higher than those of salt-affected soils. High salinity suppresses the activity of both methanogens (CH4 production) and methanotrophs (CH4 consumption). However, it imposes more inhibitory effects on methanogens than methanotrophs, resulting in lower CH4 production and subsequent emissions from these soils. Therefore, reclamation of these soils may enhance N2O and CH4 emissions. However, gypsum is the best reclamation agent, which significantly mitigates CH4 emissions from paddy cultivation in both sodic and non-sodic soils, and mitigation is higher at the higher rate of its application. Gypsum amendment increases sulfate ion concentrations and reduces CH4 emissions mainly due to the inhibition of the methanogenesis by the sulfate reductase bacteria and the enhancement of soil redox potential. Biochar is also good among the organic amendments mitigating both CH4 and N2O emission from salt-affected soils. The application of fresh organic matter and FYM enhance GHG emissions for these soils. This review suggests the need for systematic investigations for studying the impacts of various amendments and reclamation technologies on GHG emissions in order to develop low carbon emission technologies for salt-affected soil reclamation that can enhance the carbon sequestration potential of these soils.

Full textAbstract:
The black soldier fly (BSF) is recognised as a valuable insect for mitigating feed and organic waste management challenges. Thus, concerted efforts are being directed toward the promotion of the BSF. Despite the numerous advantages of BSF larvae, there are several critical environmental aspects, particularly its global warming potential, that need to be considered before large-scale adoption due to the complexity of the insect’s value chain. The direct assessment of greenhouse gas (GHG) and ammonia emissions from BSF larvae biotreatment is crucial for conducting a life cycle assessment (LCA) to evaluate the insect products’ environmental performance. This article reviews the emissions of GHG from BSF larvae bioconversion activities based on different gas sensing techniques while highlighting the factors that influence these emissions. Generally, low gas emissions were reported. However, the influence of various factors influencing emissions remains unclear, especially for nitrous oxide. We also analysed LCA studies on BSFL products while emphasising the uncertainties and variabilities among the studies. The wide variation of impact scores reported in the studies suggests that standardised guidelines should be developed to streamline methodical approaches for impact assessments pertaining to system boundaries, functional units, allocation, and system expansion assumptions. We identified several aspects for future improvements to harmonise studies in order to enhance the comparative assessment of the BSFL products.

Full textAbstract:
There has been a call for the construction industry to become more energy efficient in its planning and activities, to reduce greenhouse gas emissions to help combat climate change. The Australian Building Codes Board has implemented ‘Energy Efficiency’ standards through the National Construction Codes to direct the industry towards net zero emissions goals. However, the Board has maintained a focus on operational flows considerations despite this only being a part of the total expenditure in a building lifecycle. Embodied flows, the energy output, and emissions from harvesting, manufacturing, transporting, and manufacturing materials for a building have not been included as a part of the current standards despite their growing share in the outputs of construction. A qualitative document analysis using data from academic articles and industry publications was performed to identify the context in embodied policy development. Findings reveal an abundance of different legislations and initiatives globally, recommending techniques that may effectively achieve embodied flow reductions. The results highlighted that Australia needs to capitalize on the potential reductions in overall energy and emissions from construction. Other regions have provided a strategic and legislative basis for the industry to emulate.

Full textAbstract:
Ship building, as an energy-intensive sector, produces significant amounts of air emissions, including greenhouse gases. Most research in greenhouse gas reductions from shipping concentrates on the reduction in emissions during the operational phase. However, as emissions during ship operation are reduced, the construction and dismantling phases of ships are becoming increasingly important in the assessment of the life-cycle impact of ships. In this study, priorities for a Turkish shipyard to become energy efficient were identified by means of a semi-structured questionnaire and an interview. This was undertaken using Fuzzy Multi-Criteria Decision-Making methods, including the Fuzzy Analytical Hierarchy Process and Fuzzy Order of Preference by Similarity to Ideal Solution, which are part of a proposed systematic and transdisciplinary Energy Management Framework and System. By applying Multi-Criteria Decision-Making methods, this framework supports the shipyard’s decision makers to make rational and optimized decisions regarding energy sectors within their activities. Applying the framework has significant potential to help achieve good product quality while reducing costs and environmental impacts, and can thereby enhance the sustainability of shipping. Moreover, the framework can boost both business and socio-economic perspectives for the shipyard, and improve its reputation and competitiveness, in alignment with achieving the Nationally Determined Contributions of States under the Paris Agreement.

Full textAbstract:
Nitrogen (N) deposition has increased in recent years and is significantly affected by global change and human activities. Wetlands are atmospheric CH4 and N2O sources and may be affected by changes in N deposition. To reveal the effects of increased N deposition on peatland greenhouse gas exchange, we observed the CH4 and N2O emissions from controlled microcosms collected from a temperate peatland in the Xiaoxing’an mountains, Northeast China. We found that the moss biomass did not change, but the total herb biomass increased by 94% and 181% with 5 and 10-times-higher N deposition, respectively. However, there were no significant changes in CH4 emissions from the microcosms with N addition. The unchanged CH4 emissions were mainly caused by the opposite effect of increased nitrate and ammonium concentrations on soil CH4 production and the increased plant biomass on CH4 emission. We also found that the manipulated microcosms with 5 and 10-times-higher N deposition had 8 and 20-times-higher seasonal average N2O emissions than the control microcosms, respectively. The increased N2O emissions were mainly caused by short-term (≤7 d) pulse emissions after N addition. The pulse N2O emission peaks were up to 1879.7 and 3836.5 μg m−2 h−1 from the microcosms with 5 and 10-times-higher N deposition, respectively. Nitrate and ammonium concentrations increasing in the soil pore water were the reason for the N2O emissions enhanced by N addition. Our results indicate that the increase in N deposition had no effects on the CH4 emissions but increased the N2O emissions of the temperate peatland. Moreover, pulse emissions are very important for evaluating the effect of N addition on N2O emissions.

The earth’s average temperature has risen by approximately 1.2 °C since the 1900s. The COP26 resolution aimed to achieve carbon neutrality before 2050, while China has committed a more aggressive timetable to actually achieve the goal. It requires either that activities must not release any greenhouse gases or the emitted greenhouse gases must be offset. The logistics and transport activities contribute a lot to global greenhouse gas emissions on Earth. There are a no. of challenges of the logistics industry that are discussed, then the paradigmatic solutions such as green procurement, green packaging, green transport, and green warehousing, are respectively discussed. The three contemporary concepts of green solutions (circular economy, carbon neutrality and green cocreation) for logistics and transportation are explored. Subsequently, a detailed case study of CN Logistics’ contemporary green solutions is used to illustrate how to tackle the problems and exemplify the best practices to the other 3PL players. There are expected changes on green directives from the HKSAR Government on logistics green compliances. Finally, this paper concludes with an appeal to the industry to start the green journey immediately.

AbstractThe rapidly changing global climate due to increased emission of anthropogenic greenhouse gases (GHGs) is leading to an increased occurrence of extreme weather events such as droughts, floods, and heatwaves. The three major GHGs are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). The major natural sources of CO2 include ocean–atmosphere exchange, respiration of animals, soils (microbial respiration) and plants, and volcanic eruption; while the anthropogenic sources include burning of fossil fuel (coal, natural gas, and oil), deforestation, and the cultivation of land that increases the decomposition of soil organic matter and crop and animal residues. Natural sources of CH4 emission include wetlands, termite activities, and oceans. Paddy fields used for rice production, livestock production systems (enteric emission from ruminants), landfills, and the production and use of fossil fuels are the main anthropogenic sources of CH4. Nitrous oxide, in addition to being a major GHG, is also an ozone-depleting gas. N2O is emitted by natural processes from oceans and terrestrial ecosystems. Anthropogenic N2O emissions occur mostly through agricultural and other land-use activities and are associated with the intensification of agricultural and other human activities such as increased use of synthetic fertiliser (119.4 million tonnes of N worldwide in 2019), inefficient use of irrigation water, deposition of animal excreta (urine and dung) from grazing animals, excessive and inefficient application of farm effluents and animal manure to croplands and pastures, and management practices that enhance soil organic N mineralisation and C decomposition. Agriculture could act as a source and a sink of GHGs. Besides direct sources, GHGs also come from various indirect sources, including upstream and downstream emissions in agricultural systems and ammonia (NH3) deposition from fertiliser and animal manure.

AbstractClimate change has been viewed to result from anthropogenic human activities that have significantly altered the Nitrogen (N) cycle and carbon cycles, increasing the risks of global warming and pollution. A key cause of global warming is the increase in greenhouse gas emissions including methane, nitrous oxide, and carbon among others. The context of this chapter is based on a comprehensive desktop review on published scientific papers on climate change, greenhouse emissions, agricultural fertilizer use, modeling and projections of greenhouse gases emissions. Interestingly, sub-Saharan Africa (SSA) has the least emissions of the greenhouses gases accounting for only 7% of the total world’s emissions, implying that there is overall very little contribution yet it has the highest regional burden concerning climate change impacts. However, the values could be extremely higher than this due to lack of proper estimation and measurement tools in the region and therefore, caution needs to be taken early enough to avoid taking the trend currently experienced in developed nations. In SSA, agricultural production is the leading sector in emissions of N compound to the atmosphere followed by energy and transportation. The greatest challenge lies in the management of the two systems to ensure sufficiency in food production using more bioenergy hence less pollution. Integrating livestock and cropping systems is one strategy that can reduce methane emissions. Additionally, developing fertilizer use policy to improve management of fertilizer and organic manure have been potentially considered as effective in reducing the effects of agriculture activities on climate change and hence the main focus of the current chapter.

Greenhouse Gas (GHG) emissions occur, more or less, in all aspects of the petroleum industry's activities. Besides the direct emissions of some GHG, the petroleum industry is also characterised with high energy intensity usually followed by emissions of adverse gases, especially at old facilities, and also the products with high emission potential. Being the global industry and one of the major players on global market, the petroleum industry is also subjected to global regulatory provisions regarding GHG emissions. In this chapter, the impact of global climate change on the petroleum industry is discussed. The emissions from the petroleum industry are analysed with a special focus on greenhouse gases that occur in petroleum industry activities and types and sources of emissions from the petroleum industry activities. In addition, recommendations for estimation, monitoring, and reductions of GHG emissions from the petroleum industry are given.

There is an increasing number of regulatory and public policy initiatives aimed at improving building energy efficiency, recognizing the importance of the built environment to achieve lower energy-related emissions. However, these efforts have generally focused on the building scale. A comprehensive reduction of carbon emissions from construction requires a wider focus, considering the building as well as the lifecycle of materials and their supply chains. There is a need for robust analysis of the Greenhouse Gas (GHG) implications of construction supply chains and to optimize supply chains configurations so as to minimize GHG emissions across multiple organizations. This chapter provides a rigorous means of assessing the dynamic and complex supply chains of construction to obtain optimal and sustainable levels of GHG reductions in a whole-of-chain approach. Outcomes represent critical new knowledge, enabling deeper understanding as well as enhanced capacity to maximize energy savings from the built environment.

There are few studies on the role of institutions in achieving sustainable development that infer that these institutions offer the mechanisms for resource and environmental management. Thus, twelve West African countries (Benin, Burkina Faso, Cote d'Ivoire, Gambia, Ghana, Liberia, Mali, Niger, Nigeria, Senegal, Sierra Leone, and Togo) are covered in the study using data from World Development Indicators and World Governance Indicators. Six main outcome variables are used. These are CO2 emissions per capita, CO2 emissions from electricity and heat production, CO2 emissions from liquid fuel consumption, CO2 emissions from manufacturing and construction, total greenhouse gas emissions (kt of CO2 equivalent), and CO2 intensity. A two-step generalised method of moment (GMM) found that governance effectiveness and regulatory quality as curtails the rate of CO2 emissions. Policy implications are discussed.

The pollution prevention (P2) approach known as source reduction is being used worldwide to reduce the deleterious effects on human health and the environment due to the contaminants released from a variety of industrial sources. This chapter focuses on the concept of pollution prevention approaches undertaken by the U.S.EPA. P2 approach is discussed by applying the concept of energy efficiency, energy savings, greenhouse gas emission (GHG) reductions, waste reduction, and stormwater management to local schools, restaurants, hospitals, and the industrial sector in Ohio, USA. Several publicly available tools were used to analyze data collected during assessments. The major tools used are the Energy Assessment Spreadsheet tool (developed by Air Pollution Research Group at the College of Engineering, The University of Toledo, Ohio, USA) for the energy savings and Economic Input Life Cycle Assessment tool (developed by researchers at the Green Design Institute of Carnegie Mellon University) for the estimation of environmental emissions from industrial activities.These approaches result in the reduction of financial costs for waste management, cleanup, health problems, and environmental damage. Outcomes of pollution prevention activities are knowledge-based, behavioral, health-related, or environmental, which includes decreased exposure to toxins, conservation of natural resources, decreased release of toxins to the environment, and cost savings. The chapter presents case studies that focused on energy, greywater reuse, and food waste diversion from landfills.

Full textAbstract:
The environmental impact of concentrated animal farming operations has become serious social issues, with the livestock wastes contaminating waterways and groundwaters and generating greenhouse gas (GHG) emissions that are responsible for more than half the total GHG emissions in agricultural activities in the U.S. These impacts are mostly due to the current practice of spraying manure or manure digestate on croplands. We have recently developed two novel processes not only to mitigate the impacts stemming from the current manure management practice but also to bring in extra revenues to livestock farmers, which should provide an incentive to the farmers, by recovering value-added products from livestock manure or manure digestate. In this review, we discuss the effectiveness of the processes to produce two products: protein hydrolysate feed additives from the manure-digestate solid by one process and renewable ammonia from the manure-digestate liquid by another. One process uses thermal hydrolysis to extract protein from manure-digestate solid at a moderate recovery rate of more than 60%. Another employs acid-base reactions to strip NH3 from manure-digestate liquid and dissolve the stripped NH3 gas into the water at a high recovery rate of 90%. By repeating this stripping process, the nitrogen concentration in the water can reach as high as 18%.

Full textAbstract:
The management of municipal solid wastes (MSW) in Puerto Rico is becoming increasingly challenging. In recent years, several of the older landfills have closed due to lack of compliance with federal landfill requirements. Puerto Rico is an island community and there is limited space for construction of new landfills. Furthermore, Puerto Rico residents generate more waste per capita than people living on the continental US. Thermal treatment, or waste to energy (WTE) technologies are therefore a promising option for MSW management. It is critical to consider environmental impacts when making decisions related to MSW management. In this paper we quantify and compare the environmental implications of thermal treatment of MSW with modern landfilling for Puerto Rico from a life cycle perspective. The Caguas municipality is currently considering developing a thermal treatment plant. We compare this to an expansion of a landfill site in the Humacao municipality, which currently receives waste from Caguas. The scope of our analysis includes a broad suite of activities associated with management of MSW. We include: (i) the transportation of MSW; (ii) the impacts of managing waste (e.g., landfill gas emissions and potential aqueous run-off with landfills; air emissions of metals, dioxins and greenhouse gases) and (iii) the implications of energy and materials offsets from the waste management process (e.g., conversion of landfill gas to electricity, electricity produced in thermal treatment, and materials recovered from thermal treatment ash). We developed life cycle inventory models for different waste management processes, incorporating information from a wide range of sources — including peer reviewed life cycle inventory databases, the body of literature on environmental impact of waste management, and site-specific factors for Puerto Rico (e.g. waste composition, rainfall patterns, electricity mix). We managed uncertainty in data and models by constructing different scenarios for both technologies based on realistic ranges of emission factors. The results show that thermal treatment of the unrecyclable part of the waste stream is the preferred option for waste management when compared to modern landfilling. Furthermore, Eco-indicator 99 method is used to investigate the human health, ecosystem quality and resource use impact categories.

Full textAbstract:
Remediation of environmental sites is of concern across the rail industry. Impacted sites may result from releases of chemicals to the environment along active rail lines or in rail yards; historical activities; or through acquisition of impacted property. Management of these liabilities may require investigation, planning, design, and remediation to reduce risks to human health and the environment and meet regulatory requirements. However, these investigation and remediation activities may generate unintended environmental, community, or economic impacts. To address these impacts, many organizations are focusing on the incorporation of sustainability concepts into the remediation paradigm. Sustainable remediation is defined as the use of sustainable practices during the investigation, construction, redevelopment, and monitoring of remediation sites, with the objective of balancing economic viability, conservation of natural resources and biodiversity, and the enhancement of the quality of life in surrounding communities (Sustainable Remediation Forum [SURF]). Benefits of considering and implementing measures to balance the three pillars of sustainability (i.e., society, economics, and environment) may include lower project implementation costs, reduced cleanup timeframes, and maximizing beneficial while alleviating detrimental impacts to surrounding communities. Sustainable remediation has evolved from discussions of environmental impacts of cleanups (with considerable greenwashing), to quantifying and minimizing the environmental footprint and subsequent long-term global impacts of a remedy, and currently, incorporating strategies to address all three components of sustainability — environmental, social, and economic. As organizations expand their use of more sustainable approaches to site cleanup, it is beneficial to establish consistent objectives and metrics that will guide implementation across a portfolio of sites. Sustainable remediation objectives should be consistent with corporate sustainability goals for environmental performance (e.g., greenhouse gas emissions, resource consumption, or waste generation), economic improvements (i.e., reduction of long term liability), and community engagement. In the last decade, there have been several Executive Orders (13423, 13514, 13693) that provide incrementally advanced protocols for achieving sustainability in government agency and corporate programs. Resources for remediation practitioners are available to assist in developing sustainable approaches, including SURF’s 2009 White Paper and subsequent issue papers, ITRC’s Green and Sustainable Remediation: State of the Science and Practice (GSR-1) and A Practical Framework (GSR-2), and ASTM’s Standard Guide for Greener Cleanups (E2893-16) and Standard Guide for Integrating Sustainable Objectives into Cleanup (E2876-13). These documents discuss frameworks that may be applied to projects of any size and during any phase of the remediation life cycle, and many provide best management practices (BMPs) that may be implemented to improve the environmental, social, or economic aspects of a project. Many of these frameworks encourage a tiered approach that matches the complexity of a sustainability assessment to the cost and scope of the remediation. For small remediation sites, a sustainability program may include the selection, implementation, or tracking of BMPs. A medium sized remediation site may warrant the quantification of environmental impacts (e.g., air emissions, waste generation, etc.) during the evaluation and selection of remedial alternatives. Often, only large and costly remediation sites demand detailed quantitative assessment of environmental impacts (e.g., life cycle assessment), economic modeling, or extensive community or stakeholder outreach. However, if a tiered approach is adopted by an organization, components of each of these assessments can be incorporated into projects where it makes sense to meet the needs of the stakeholders.

Each economy must adapt its activities to the protection of the environment. It is now an essential part of everyday life, in the face of various climate changes. The Europe 2020 strategy sets out a set of objectives in the EU, including those promoting environmental sustainability, called sustainable growth. The aim of the paper is to determine, if the performance of the country, in the area of greenhouse gas emissions reduction is adequate to the strategy Europe 2020. In the analysis of greenhouse gas emission reductions, we will also focus on the agriculture sector and compare the development over time with the development in other EU countries. The analyzed period is 10 years, from 2009 - 2018. The article investigated the performance of greenhouse gas emissions in the example of EU (including the Great Britain) countries.

Green-House Gases (GHGs) are emitted into the atmosphere in significant amounts produced mainly by human sources and activities. Globally, the road transport sector is a significant source of GHGs and particularly of CO2 emissions. Transport sector includes pavements and pavement roughness is a factor that directly affects fuel consumption and consequently has a significant impact on vehicle emissions. Many studies have attempted to define the connection between pavement roughness in terms of International Roughness Index (IRI) and fuel consumption, under the scope of pavement sustainability. However, the requirements of multiple parameters and extensive data processing have raised the need for solid and simplified approaches in practice. As such, the objective of the current study is to incorporate the assessment of vehicle emissions into pavement management processes by formulating a simple and credible relationship between vehicle GHGs and pavement roughness. Analysed data comes from multiple segments of two interurban controlled-access highways with different pavement condition. Several combinations of vehicle and fuel type suggest the development of concise formulas to estimate equivalent CO2 emissions based on IRI measurements. Verification and validation of the developed formulas was applied via appropriate statistical techniques.

Abstract The transition to a climate-neutral society is both an urgent technical challenge and yet long-term CAPEX heavy requiring huge investments from industry and governments. Major oil and gas (O&G) operators around the globe have already established their decarbonization targets and even though upstream accounts for two-thirds of total emissions in the petroleum industry, both new well construction designs, and improved workover operations are proving to be effective measures in minimizing greenhouse gas (GHG) emissions while being economically viable. A novel completion technology has been installed in 114 wells in Russia since 2018 to eliminate sustained annular casing pressure (SAP) throughout the lives of wells and combat the associated release of carbon dioxide (CO2) and methane into the atmosphere. Since methane is much more powerful and has a 28-34 times more global warming potential compared to CO2 over the hundreds of years, and 84-86 times more potent over a 20-year timeframe respectively, these types of simple, yet efficient solutions represents enormous benefits to operators in reducing their carbon taxes while tackling climate change. Moreover, the installation of this technology resulted in reliable downhole well integrity of traditionally problematic wells, without the need for subsequent squeeze cementing operations. These types of completion solutions set both in an open and cased hole, allow operators not just to customize their cementing program and meet regulatory approvals, but also greatly reduce their reported carbon emissions. A summary of the results and efficiencies achieved with these installations will be presented and will be compared to conventional technologies. In addition, more than 15,000 lightweight e-line intervention operations have been performed both in Russia and Kazakhstan since 2011 which contributed to fewer emissions of hazardous greenhouse gases into the air versus conventional coiled tubing operations. These types of light interventions use less diesel to operate and with fewer people and equipment, leave a smaller carbon footprint on each well location which in turn makes a difference when it comes to GHG emission reduction. A comparison breakdown of coiled tubing versus e-line mechanical interventions will be statistically analyzed. This paper will illustrate how these newer technologies contributed to GHG emission reduction and how simultaneously economical efficiencies were achieved during well completion and intervention activities through reduced rig time and faster job execution compared to conventional methods. It will also review case histories from fields across the region using these installations and analyze each method. The field data will present the development, installation, and operational sequence and explain how each setup was tailored to meet both specific operational needs and to reduce greenhouse emissions, mainly by minimizing gas flaring. Widespread implementation of such technologies would help operators meet their emission targets and contribute to the reduction of the earth's climate change.

Abstract Khurais Producing Department, as one of Saudi Aramco's producing facilities, is sharing this paper to highlight implemented breakthrough innovative solutions and technologies with massive positive impact on the environment. These technologies were introduced to increase the operation reliability, reduce the Greenhouse Gases (GHG) emissions and carbon footprint, and promote circular economy by optimizing power consumption, generating clean power, and eliminating daily routine flaring towards Saudi Aramco's ambition of achieving net-zero Scope 1 and Scope 2 greenhouse gases emissions by 2050, which is a step towards achieving Saudi Arabia's commitment to net-zero by 2060. Driven by the commitment of Khurais managements toward the Saudi Aramco defined environmental protection policies through Khurais Environmental Management System (EMS) that meets the requirements of ISO 14001:2015 and strives for continual improvement, Khurais has set its objectives for protecting the environment and reducing the impact of its day-to-day operation on the surrounding environment. To achieve these objectives, Khurais has developed different plans, such as the Flare Minimization Plan and GHG Assurance Plan, and established key performance indicators (KPIs) through the Operational Excellence (OE) system to track and enhance the environmental performance of the facility. To achieve the objectives identified by Khurais managements and to support their commitment plan for protecting the environment, different initiatives and technologies were deployed at Khurais facility which have significantly contributed to GHG emission reduction. The implemented initiatives include: a) construction of steam turbine generator (STG) part of the combined cycle cogeneration plant to generate clean power, b) installing flare gas recovery system to recover daily routine flaring from the facility, c) deploying the first worldwide Advanced Process Control (APC) for oil production wells for conventional oilfield for optimizing energy consumption, d) installing a swing line connecting all five oil trains’ HP Compressor suction lines to share the feed gas, e) flare minimization during running Oil Train-4 with bypassing damaged stabilizer which was a patented solution deployed to achieve the facility MSC post the attack on Khurais facilities, f) deployment of nonmetallic resin thermal pipe (RTP) material technology for over 60% of the massive crude pipeline network, and g) full deployment of closed draining systems through the construction of WOSEP blowdown system and automatic crude tank dewatering system. This paper will share Khurais efforts in implementing these initiatives and technologies, which touch base on different sources for GHG emission from the facility such as power consumption, flared gas, and material release to the atmosphere. Identifying a plan and implementing these initiatives have contributed to reducing the GHG emissions from Khurais facility.

Abstract Environmental requirements have led the air transportation industry to work towards reducing greenhouse gas emissions and mechanical noise levels. Nowadays, this sector contributes with 2% of the total greenhouse gas emissions, and there is a demand from global aviation regulators for further reducing this percentage. In the last years, the development of Hybrid-Electric Propulsion Systems (HEPSs) has grown. The HEPS combines an Internal Combustion Engine (ICE), for example, Gas Turbine (GT) or reciprocating engine, with an Electric Motor (EM), combining the inherent advantages of both. HEPSs present increased efficiency and operating safety in comparison with conventional ICE-powered systems. Furthermore, they can supply the electrical devices with power. This area of study is multidisciplinary in nature and, therefore, poses research challenges on ICEs, EMs, electronic converters, propeller design, monitoring and control systems, management and supervision systems, energy efficiency and optimization, aerodynamics and aircraft mechanical design. A research project aimed at the characterisation of hybrid-electric aircraft propulsion systems, and the construction of a HEPS prototype, is underway in Brazil. The system is essentially composed of a GT, an EM, three electronic converters, a battery bank and a propeller. It can operate with three different topologies: series, full-electric and turbo-electric. A test bench with all the necessary peripheral and analysis infrastructure is under construction. Present work aims to: (i) develop simplified models for all the test bench components, (ii) given a mission profile, show the results of an initial energy management computing code that determines the optimal hybridization strategy, and (iii) simulate various operating alternatives for the chosen mission profile. The results (i) highlight the impact of critical characteristics of the batteries on the HEPS performance, and (ii) demonstrate the application of the management code on optimizing the aircraft energy consumption for a given mission profile.

Full textAbstract:
The climate crisis is urging us to act fast. Buildings are a key leverage point to reduce greenhouse gas (GHG) emissions, but the embodied emissions related with their construction remain often the hidden challenge of any ambitious policy. Considering that a complete material substitution is not possible, we explore in this paper a material GHG compensation where fast-growing bio-based insulation materials are used to compensate building elements that necessarily release GHG. Looking for analogies with other human activities, different material diets as well as different building typologies are modelled to assess the consequences in term of bio-based insulation requirement to reach climate-neutrality. The material diets are defined according to the gradual use of herbaceous materials, from the insulation up to the structural level: omnivorous, vegetarian and vegan. Our results show the relationship in terms of volume between the climate intensive materials and the climate-negative ones needed to neutralize the overall building GHG emissions. Moreover, they suggest how climate-neutral building can look like and that it is possible to have climate-neutral buildings with wall thickness within the range of current construction practices.

Full textAbstract:
Reducing Emissions from Deforestation and Forest Degradation (REDD+) is a voluntary international initiative to reduce greenhouse gas emissions from deforestation and forest degradation and to promote conservation and sustainable management of forests. It has significant implications for tenure rights, including for women. Although women use forests to support their own as well as their families’ livelihoods, they are frequently overlooked as key stakeholders. Women often face discrimination in resource management processes, largely through unequal, insecure, or unclear tenure rights. Hence, there is a significant risk that the implementation of REDD+ could exacerbate existing inequalities for women. Securing women’s tenure rights is fundamental, as tenure rights provide recognized rights-holders with the ability to be involved in and to benefit from the design and implementation of REDD+ activities.
