متن کاملGreenhouse gas emissions from flying can offset the gain from reduced driving in dense urban areas
Numerous studies have illustrated how denser urban forms lead to smaller greenhouse gas (GHG) emissions from passenger transport. Many of these studies have excluded aviation since the association between urban structure and air travel is not as intuitive as it is the case of ground travel. However, several recent studies have concluded that air travel is a significant contributor to the GHGs f...
متن کاملGreenhouse gas emissions from rice
Rice provides the staple food for over 60% of the world’s population. Globally 80% of rice is grown by small farmers in low income and developing nations, and in India rice farming is a key source of employment for the 60% of Indian workers still dependent on agriculture for work.

متن کاملGreenhouse Gas Emissions from Livestock and Poultry
In 2008 the Environmental Protection Agency (EPA) estimated that only 6.4% of U.S. greenhouse gas (GHG) emissions originated from agriculture. Of this amount, 53.5% comes from animal agriculture. Agricultural activities are the largest source of N2O emissions in the U.S. accounting for 69% of the total N2O emissions for 2009. In animal agriculture, the greatest contributor to methane emissions ...
