One of the major factors, contributing to the emission of greenhouse gases in the environment is generation of pollutant gases in municipal landfills. As for the design and building of a gas collecting system, it is necessary to properly estimate the amount and type of the landfill emissions. By means of LandGEM model, this study predicts the amount and type of the landfill gases, produced for ...

The analysis of gas emissions by an input-output subsystem approach provides detailed insights into pollution generation in an economy by revealing the channels by which the environmental burdens are caused and transmitted throughout the production system. In this paper we propose a decomposition of the greenhouse gas emissions by using an input-output subsystems model. The empirical applicatio...

M anagement of livestock wastes can affect greenhouse gas emissions through attenuating both methane and nitrous oxide emissions, as well as by displacing carbon dioxide emissions from fossil fuel use that can be avoided through biogas production and use. Methane is naturally produced from the anaerobic decomposition of livestock manure and is a potent greenhouse gas with 21 times the greenhous...

There are many good reasons to promote sustainable development and reduce greenhouse gas emissions and other combustion emissions. The air quality in many urban environments is causing many premature deaths because of asthma, cardiovascular disease, chronic obstructive pulmonary disease, lung cancer, and dementia associated with combustion emissions. The global social cost of air pollution is a...

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...

Whether through sea level rise or wetland restoration, agricultural soils in coastal areas will be inundated at increasing rates, renewing connections to sensitive surface waters and raising critical questions about environmental trade-offs. Wetland restoration is often implemented in agricultural catchments to improve water quality through nutrient removal. Yet flooding of soils can also incre...

The increased urgency of dealing with mitigation of the looming climate change has sparked renewed interest in the nuclear energy option. There exists a substantial stream of research on the amount of embodied energy and greenhouse gas emissions associated with nuclear generated electricity. While conventional fossil fuelled power plants cause emissions almost exclusively from the plant site, t...

the goal of this study was to analysis the greenhouse gas (ghg) emissions of pasta production. data for this study was collected from durum wheat farms of three provinces of iran. data of soil properties, transportation and pasta factory stages were collected and analyzed, using simapro software, ecoinvent data base and global warming potential (gwp) 100 years method. epic model was used to cal...

Wetland ecosystems are important reservoirs of biodiversity and significantly contribute to emissions of the greenhouse gases CO2, N2O, and CH4. High anthropogenic nitrogen (N) inputs from agriculture and fossil fuel combustion have been recognized as a severe threat to biodiversity and ecosystem functioning, such as control of greenhouse gas emissions. Therefore, it is important to understand ...

Sanitary landfill is the common strategy for municipal solid waste management in developing countries. Anaerobic decomposition of disposed wastes in landfill under favorable conditions will lead to the landfill gas (LFG) emissions, considering as emerging air pollutants. The emission of greenhouse gases, including methane, resulting from municipal solid waste disposal and treatment processes ar...
