EPA Proposes Transport Rule to Cut Pollution from Power Plants in 31 States and DC; New Approach for Pollution Reduction

Green Car Congress

The US Environmental Protection Agency (EPA) is proposing regulations employing the “good neighbor” provision of the Clean Air Act to reduce interstate transport of upwind state emissions from power generation that contribute to air quality problems in downwind states. standards established in 2006 and the 1997 annual PM 2.5

The decrease in CO 2 equivalent emissions of ODSs (ozone-depleting substances: CFCs, halons, HCFCs, and others) may be offset by the projected increase in their non-ozone depleting substitutes (HFCs) (lines designated as HFC scenarios). Climate and the Ozone Layer. Source: UNEP. Click to enlarge.

Report argues advanced HD natural gas vehicles foundational for California to hit air and climate goals; near zero-emission potential

Green Car Congress

Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. An 80% reduction of GHG emissions is targeted for 2050, relative to 1990 levels.

Research shows clean fuel-use for ships off California coast extremely effective in reducing sulfur dioxide pollution

Green Car Congress

The California data were compared to ship-plume measurements made by NOAA near the Port of Houston, Texas in 2006. Ships, especially ocean-going vessels, are powered by very large diesel engines that generate a tremendous amount of pollution impacting air quality onshore.

MIT study finds air quality co-benefits of US carbon policies can significantly offset costs, depending upon the policy

Green Car Congress

The three were designed to resemble proposed US climate policies, with the clean-energy standard requiring emissions reductions from power plants similar to those proposed in the Environmental Protection Agency’s Clean Power Plan. Savings from health benefits dwarf the estimated $14 billion cost of a cap-and-trade program.
