Biomass fuels are typically burned with substantial production of non-CO 2 GHGs with greater radiative forcing, indicating that biomass fuels have the potential to produce net global warming commitments even when grown renewably. 展开 关键词: Greenhouse gases Air pollution Fuel combustion Domestic fuels...
Recent atmospheric measurements indicate that concentrations of greenhouse gases are increasing. Atmospheric methane concentration has increased at about 1% annually to 1.7 ppmV during the last decades (Khalil and Rasmussen, 1987). The resulting effect on global temperature is highly significant because ...
Greenhouse Gases and Ammonia Emission Factors from Livestock Buildings for Pigs and Dairy Cows 来自 国家科技图书文献中心 喜欢 0 阅读量: 88 作者: Rzeznik, Wojciech,Mielcarek, Paulina 摘要: Ammonia (NH3) and methane (CH4) emissions from naturally ventilated dairy barns affect the environment and the...
In general, there is an increase in the concentration of gases towards the inner part of the river, in all three systems. Daily variations coupled to the tidal cycles were also observed in the three estuaries. The highest concentrations were measured during ebb, which suggests that the ...
Increased concentrations of greenhouse gases (GHGs) such as methane (CH4) and nitrous oxide (N2O) are of environmental concern because of their implications on the global climate (Aneja et al., 2001, IPCC, 2001, IPCC, 2013). Livestock production is an important source of GHG emissions into ...
It also reduces emissions of greenhouse gases fromprimary production by 19%. A switch from beef or sheepmeat (red meat) to pork orpoultry (white meat) reduces food consumption related greenhouse gas emissionsand the land area required... E Audsley,A Angus,JC Chatterton,... 被引量: 5发表:...
Energy Technology Options for Integrated Reduction of Greenhouse Gases Emission factors for all important energy-related greenhouse gas sources are compiled and a large number of emission reduction technologies is characterized. The results of the integrated reduction strategies indicate that the inclusion of...
” Notwithstanding important recent progress in developing renewable fuel sources, low fossil fuel prices could discourage further innovation in, and adoption of, cleaner energy technologies. The result would be higher emissions of carbon dioxide and other greenhouse gases. [B]Policymakers should not ...
the facilities’ conventional air pollutants and greenhouse gases, with likely regulatory consequences. In aFederal Registernotice slated for publication Feb. 9, EPA announces a proposed consent decree that would require it to issue draft emission factors -- or to determine that such an update is....
The amount of cement used has increased phenomenally due to the development and massive expansion of the infrastructure sector. The manufacture of cement requires more incredible embodied energy and produces greenhouse gases. Geopolymer concrete (GPC) was developed to alleviate the environmental adverse ef...
