Greenhouse gas emissions

The lack of country-specific greenhouse gas (GHG) emission factors vehicles in Vietnam makes the emissions inventory in the transport sector more difficult. This study developed the country-specific GHG emission factor in terms of CO2 equivalent for motorcycles (MCs) in Hanoi to overcome the above impediment.

The swine farming has a significant potential for biogas emissions and is a substantial contributor to greenhouse gas emissions within Vietnam's agricultural sector. This study was conducted to determine the total amount of CH4, and CO2 (eq) released from mature management activities and emission coefficients of CH4 and CO2 (eq) at different swine farms in Northern, Central and Southern regions, using tier 1 and tier 2 according to IPCC method.

This research explores whether Environmental Management Accounting can be applied to assist an Australian cogeneration company in improving both its financial performance as well as its environmental performance. Cogeneration or ‘combined heat and power’, in this particular case, involves the simultaneous production of heat and electricity using a single fuel, that is, natural gas. The heat generated is then used to produce steam to meet the customers’ requirements as well as boost the production of electricity.

In this research, a bi-objective hybrid vehicle routing problem is presented and solved by considering alternative paths, various lengths and reliabilities. The first objective function minimizes overall system costs, fuel consumption, and greenhouse gas emissions, whereas the second objective function maximizes the reliability of the entire system with alternative paths and several reliabilities.

The sustainability and prosperity of the ancient civilizations of China, Egypt, Babylonia, Phoenicia, Persia and Roma were based on the extensive use of water for human consumption, crop irrigation, canal navigation and energy generation. Today, the worldwide scarcity of water and clean energy constitutes a central and critical problem for the whole humankind. This situation is aggravated as industrial, agricultural and municipal effl uents reach the water bodies, or the coastal seawater that is used as feed for desalination plants.

Landfill gas from a source of green energy, clean, renewable and can be used to create electricity, or used in the energy industry. This paper reviews the potential energy recovery landfill gas from municipal solid waste, to reducing methane emissions in particular, and reduced greenhouse gas emissions in general. In addition, this paper provides an assessment using the model of methane generated from landfill municipal solid waste and generate energy potential of gas recovered. In particular, this paper uses a life cycle assessment methods ......

Natural resource managers and conservationists are coming to grips with the fact that rapid global warming and associated climate changes are already having a considerable impact on the world’s ecological systems. More and larger shifts are expected, even in the best-case scenarios for greenhouse gas emissions reductions and future warming. These climate changes are ushering in a fundamental shift in natural resource management and conservation, to help natural systems withstand and adapt to new climate conditions.

To appropriately mitigate environmental impacts from transportation, it is necessary for decision makers to consider the life-cycle energy use and emissions. Most current decision-making relies on analysis at the tailpipe, ignoring vehicle production, infrastructure provision, and fuel production required for support. We present results of a comprehensive life-cycle energy, greenhouse gas emissions, and selected criteria air pollutant emissions inventory for automobiles, buses, trains, and airplanes in the US, including vehicles...

The scientific evidence is clear: before 2020 global greenhouse gas emissions (GHG) must peak and by 2050 they must be reduced by 50-85% below 2000 levels, in order to avoid a rise in global temperature of 2°C or more above the preindustrial level.2 Without ambitious international action, new scientific research3 predicts close to, or even more than, a metre of sea level rise by the end of this century, due to melting glaciers and expansion of the oceans. Tthese and other changes will have serious economic and human consequences....

China stands front and center in the congressional debate on climate change, due to that nation’s contribution to global emissions and competitiveness in global trade. With its large population, rapidly expanding economy, and heavy reliance on coal, China now shares the lead in global greenhouse gas (GHG) emissions with the United States. China’s GHG emissions are expected to continue growing in the years ahead based on projections of continuing rapid economic growth.
