The proper selection of treatment technologies may be an important opportunity for contributing to the reduction goals of greenhouse gases (GHG) emissions. Based on actual Mexican infrastructure data, the scenarios analyzed in this work show that the emission reduction from sewage treatment in Mexico could be as high as 34% if compared to the baseline scenario, depending on the treatment techno...

Now in these days’ green house gases is the main cause of global warming and affects the climate in the world. Environmental arguments centre on the need to reduce greenhouse gases (GHGs) emissions for the sake of both the global and local climate, particularly in large cities. Excessive exploitation of natural resources for development has been resulted into many environmental problems like en...

The results of economic models of greenhouse gas reduction depend sensitively on the assumptions embedded in the energy scenarios chosen, both for business-as-usual and emission reduction scenarios. In this paper, some of the basic requirements of useful scientific models are reviewed and then, as a case study, applied to the MEGABARE computer model of greenhouse response in the global economy....

Environmental issues have become increasingly important in the political arena, particularly with growing concern over the "greenhouse effect", a potential global climatic warming caused by increases in anthropogenic emissions of greenhouse gases. The United States alone accounts for 25% of the worldwide emissions of C02, the most important of the greenhouse gases. The generation of electric po...

Most OECD countries are committed to reducing their emissions of greenhouse gases There is increasing scientific consensus that global warming is under way, linked at least in part to human economic activity. The considerable attention paid to this problem over the past ten years resulted not least from the 1992 United Nations (UN) Framework Convention on Climate Change (UNFCCC). Despite this a...

Crop production process utilizes input energy and produces some biomass energy as output.  During this process, greenhouse gases (GHGs) are also emitted which can make environmental risks. In this study, input and output energies, energy indices, and GHG emissions arising from inputs were estimated for wheat-cotton rotation under different tillage practices in Fars province. The study was condu...

Separation of slurry produces a solid fraction that is stored in manure heaps before being used as a fertiliser in crop production. Considerable amounts of ammonia (NH3) and greenhouse gases may be emitted during storage, which has deleterious environmental effects. The emission levels can be expected to depend on oxygenation level inside the bulk of the stored manure and therefore on storage c...
