Reducing CO2 emission and lowering the concentration of greenhouse gases in the atmosphere has quickly become one of the most urgent environmental issues. While a variety of technologies and methods have been developed, the separation of CO2 from gas streams is still a critical issue. Apart from establishing new techniques, the exploration of membrane materials with high separation performance ...

For some years now, problems relating to gas emissions that affect climate and result from human activities have assumed a global dimension of large importance. The climate is, indeed, influenced by the concentrations of some pollutants in the atmosphere; these pollutants trap the long wave radiation emitted by the Earth and alter the energy balance, causing an accentuation of the natural green...

This paper presents an application of LCA (Life Cycle Assessment) with a view to analyzing the environment aspects of rice straw-based power generation in Malaysia. It also compares rice straw-based power generation with that of coal and natural gas. GHG (Greenhouse gas) emission savings were calculated. It finds that rice straw power generation can save GHG (greenhouse gas) emissions of about ...

Understanding the sources and quantities of greenhouse gas (GHG) emissions is critical to developing an emissions inventory that accurately represents various oil and gas industry segment operations. To address this, the American Petroleum Institute (API) formed a Greenhouse Gas Emissions Methodology Working Group. The working group’s objectives were to review, summarize and recommend methodolo...

Personal greenhouse gas calculators (PGGC) are important tools to raise awareness of the impact of personal behaviour on carbon dioxide emissions. Per capita, Australians are the highest emitters of greenhouse gases in the world and the task for them to reduce emissions to sustainable levels will be particularly challenging. This paper reviews six PGGC promoted in Australia and evaluates them f...

Climate change is one of the greatest challenges worldwide. Its most severe impacts may still be avoided if efforts are made to transform current energy systems. The notion of climate change mitigation refers to the reduction of the rate of climate change via management of its causal factors such as the emission of greenhouse gases from fossil fuel combustion, agriculture, land use changes, cem...

Municipal wastewater treatment plants emit methane. Since methane is a potent greenhouse gas that contributes to climate change, the abatement of the emission is necessary to achieve a more sustainable urban water management. This requires thorough knowledge of the amount of methane that is emitted from a plant, but also of the possible sources and sinks of methane on the plant. In this study, ...

the significant consumption of gas in the world results in the emission of greenhouse gases into atmosphere. abadan refinery has always been the biggest and oldest oil refinery in the middle east and has a variety of refined products. after six months of collecting data about pollutant concentration emitted from a stack of old furnaces of units 75 and new unit 200, the emission factor of the po...

Agricultural Sector Analysis on Greenhouse Gas Emission Mitigation in the United States. (December 2000) Uwe Schneider, M.Ag., Humboldt University, Berlin; M.S., Texas A&M University Chair of Advisory Committee: Dr. Bruce A. McCarl This dissertation analyzes the economic potential of agriculture to participate in greenhouse gas emission mitigation efforts. Major agricultural mitigation strategi...

This paper deals with the modeling of the strategic allocation of greenhouse gases emission allowances in the EU-wide trading market that results from Kyoto agreement implementation. An M -matrix game is formulated where the players are countries or groups of countries that may have a strategic influence through their allocation of emission allowances and the payoffs are the welfare gains of th...
