Emission reductions in the US - Not so quick

E.P.A. Takes Step to Cut Emissions From Planes

The Obama administration said on Wednesday that it would take the first step toward regulating greenhouse gas emissions from airplanes, but it acknowledged it would most likely take years before stringent standards are enacted. 

 The Environmental Protection Agency said that emissions from airplanes endanger human health because of their contribution to global warming. This finding does not impose specific new requirements on airlines yet, but it requires the agency to develop the rules, as it has done for motor vehicles and power plants.
