EPA proposes first US greenhouse gas emissions standards for aircraft

Green Car Congress

The US Environmental Protection Agency (EPA) proposed greenhouse gas (GHG) emissions standards for airplanes used in commercial aviation and large business jets. The proposed EPA standards would address subsonic jet aircraft with a maximum takeoff mass (MTOM) greater than 5,700 kilograms and subsonic propeller-driven airplanes (e.g.,

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

This article shows that including offsets in climate change legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. Assuming the offset is legitimate—i.e.,

EPA proposes rule for nationwide 30% cut in GHG from existing power plants by 2030 relative to 2005

Green Car Congress

The US Environmental Protection Agency (EPA) released the already widely-discussed (albeit without much detail) “Clean Power Plan” proposal, which mandates a national average 30% cut in greenhouse gas emissions from existing power plants from 2005 levels by 2030. EPA is only proposing goals for states with fossil fuel-fired power plants.
