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

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 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

This research investigates ways to reduce the carbon dioxide emissions from the cement industry. Cement is one of the largest sources of man-made greenhouse gases, contributing ~5% of the global total. 40% of emissions from cement come from the fuel used in the process, while the electricity used contributes a further 5%. The focus of the research is to find operational changes that can reduce emissions without the need for large capital investment. Three cement plants in the UK were investigated using four different mathematical models based on real data from the plants. A new metric for asse

Growing concerns about interruption to oil supply and oil shortages have led to escalating global oil prices. In addition, increased public acceptance of the global warming problem has prompted car manufacturers to agree to carbon emission targets in many regions including most recently, the Californian standards.

As a result of these issues, spark ignition engines in their current form will need significant improvements to meet future requirements. One technically feasible option is smaller capacity do

The mechanical properties and the dense matrix result in lower material usage and superior durability compared to conventional concrete, but the implementation of UHPFRC in the Swedish industry has been delayed. The most evident explanation, based on interview with industry representatives, as to why UHPFRC is not commonly used in Sweden are due to the lack of standards and knowledge.

The main objective of the thesis is to seek insights into the theory, and provide empirical evidence of rebound effects. Rebound effects reduce the environmental benefits of environmental policies and household behaviour changes. In particular, win-win demand side measures, in the form of energy efficiency and household consumption pattern changes, are seen as ways for households and businesses to save money and the environment. However, these savings have environmental impacts when spent, which are known as rebound effects. This is an area that has been widely neglected by policy makers.

One way of planning an energy system in urban areas is to have integrated energy systems where synergies between different technologies and energy carriers are utilized.

碩士<br>明志科技大學<br>機械工程系機械與機電工程碩士班<br>106<br>In recent years, the energy crisis and environmental pollution issues have received international attention. All countries in the world are also actively pursuing the research and development of alternative energy sources and reducing emissions of environmental pollutants.The density of scooter in Taiwan is the highest in the world. Therefore, scooter often emit more pollutants than other private vehicles. Therefore, this study uses the general market through the fifth phase of environmental inspection scooter. And bio-butanol (butyl propionate) and ga

Emission from engine exhaust is series problem for environment point of view. For that search for alternative fuel is encouraged. The main problems with the use of neat vegetable oils in diesel engines are higher smoke levels and lower thermal efficiency as compared to diesel. The problem can be tackled by inducting a gaseous fuel in the intake manifold along with air. In this investigation, hydrogen is used as the inducted fuel. It is expected that, the problems associated with vegetable oil fueled engine like smoke and hydrocarbon emissions can be brought down by supplying hydrogen in small

碩士<br>國立臺灣海洋大學<br>機械與輪機工程學系<br>93<br>Abstract Alcohols are oxygen-enriched fuels. Thus alcoholic fuel additives are able to promote the combustion of diesel engines, and to reduce the exhaust emissions of CO and smoke. Depending on the type of alcoholic fuel additives used, the exhaust NOX emissions may increase or decrease. Isopropyl alcohol (IPA) has a similar value of specific weight as diesel fuel. It has a high potential to serve as an alternate fuel for diesel engines. This study is to investigate the effects on the performance and exhaust emissions by adding different proportions of I

So diesel engine has an important contribution in dynamic machine, such as vehicle, ship, agri-motor etc. It is effective contributions to develop world economy. But the contaminant of diesel engines, such as smoke, NOX and HC emissions will lead air pollution to damage respiratory disease. In order to reducing exhaust emission, the theme of theses analyze that super diesel fuels are added by 90% with high-purity methanol additive and 5% w

In this study, we use the characteristics of the high oxygen content and low carbon content of the alcohol fuel to reduce the concentration of pollutants in the exhaust emissions from diesel engines. In the procedure, the super diesel fuel is added by 90 wt% with high-purity butanol additive and 5 wt% water-contented butanol additive in non-modified diesel engine, respectively. The results show that the b

Atmospheric concentrations of CO2 have risen considerably since the industrial revolution due to human activity. Without extreme intervention, climate forecasts indicate that atmospheric CO2 concentrations will continue to rise. Plant growth and productivity in response to elevated CO2 has been studied extensively, however, few studies explore how reproduction will be affected under future CO2 concentration; particularly for long-lived woody plant species. This study is undertaken within the EucFACE facility in Western Sydney (Australia), with naturally growing populations, on nutrient limited

Since Nano Powder Technology has flourished in the past few years, many traditional territories in science technology and reducing wear technology can change the material of the mechanical, manufacturing processes and production methods. Many references also prove that it can reduce friction performances in Tribological territory. In this study, Nanometer Ceramic Complexes Powder Additive, also called NCCPA, is added into the origina

This study centered on a novel thermoelectric generator (TEG) integrated into the built environment. Designed by Watts Thermoelectric LLC, the TEG is essentially a novel assembly of thermoelectric modules whose required temperature differential is supplied by hot and cold streams of water flowing through the TEG. Per its recommended operating conditions, the TEG nominally generates 83 Watts of electrical power. In its default configuration in the built environment, solar-thermal energy serves as the TEG’s hot stream source and geothermal energy serves as its cold stream source. Two systems-lev
