Climate change occasioned by the accumulation of greenhouse gases (GHGs) is now widely accepted as an issue which mankind needs to address. The starting point is necessarily the determination of all the sources of emissions during the life-cycles of the studied components. Post-calculation, the results ought to be presented to decision-makers in a clear manner so as to provide the basis on whic...

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...

By 2050, the earth’s population is expected to be more than 9 billion. The need for secure food and water supply will force agriculture to increase production. The major greenhouse gases (GHGs) from the livestock sector are carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) throughout the production process. These gases are the key contributor to an in...

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...

It is widely recognized by scientific communities that human activity is altering Earth’s atmospheric composition and contributing to global climate change. Greenhouse gases (GHG), while naturally occurring elements, absorb and emit radiation within the thermal infrared range1. Activities that emit GHGs, such as transportation, manufacturing, and land use changes, concentrate these gases though...

On March 10, 2009, the US Environmental Protection Agency (EPA) proposed a new rule, Mandatory Reporting of Greenhouse Gases. When final, the rule would compel most large sources of greenhouse gases (GHGs) to report their emissions to EPA as well as fossil fuel suppliers and vehicle engine manufacturers to report their fuel sales and engine emissions rates, respectively. We suggest a number of ...

the objectives of this study was to estimation of greenhouse gases (ghg) emissions and global warming in rice production and identify measures to reducing fossil energy use and greenhouse gases emissions. three rice production systems included sri, improved and conventional were studied. all activities, field operation and data in production methods and differents inputs rates were monitored an...

This study highlights the economic and environmental challenges of recycling in Ontario, specifically examining the effect of attempting to increase the emissions target for the province’s Waste Electronics (WEEE) program. The findings from the cost model analysis found that Ontario’s Electronic Stewardship program reduces overall carbon emissions by approximately 205 thousand tonnes every year...

Emissions of CO2 and CH4 from freshwater reservoirs constitute a globally significant source of atmospheric greenhouse gases (GHGs), but knowledge gaps remain with regard to spatiotemporal drivers of emissions. We document the spatial and seasonal variation in surface diffusion of CO2 and CH4 from Douglas Lake, a hydropower reservoir in Tennessee, USA. Monthly estimates across 13 reservoir site...

HE KYOTO PROTOCOL, THE SUBJECT OF intense political and scientific debate throughout the world since its introduction in 1997, is now poised to enter into force. The Protocol establishes a “double trigger,” requiring both ratification by 55 governments (which was met in 2002) and that the ratifying governments represent at least 55% of the developed nations’ 1990 carbon dioxide emissions. Altho...
