(R134a replaced CFC-12 as the MAC refrigerant in the early 1990s due to the negative impact of CFCs on the Earth’s ozone layer. With its GWP of 1, it is also the refrigerant that has the least impact on climate. Baker (2007) Demonstration of an Energy-Efficient Secondary Loop HFC-152a Mobile Air Conditioning System.
The on-road transportation (ORT) and power generation (PG) sectors are major contributors to CO 2 emissions and a host of short-lived radiatively-active air pollutants, including tropospheric ozone and fine aerosol particles, that exert complex influences on global climate.

After a thorough scientific review ordered in 2007 by the US Supreme Court, the US Environmental Protection Agency (EPA) issued a proposal with two distinct findings regarding greenhouse gases. In both magnitude and probability, climate change is an enormous problem. harm to water resources, agriculture, wildlife and ecosystems.
EPA finds that California does not need its GHG and ZEV standards to meet compelling and extraordinary conditions because: Those standards address environmental problems that are not particular or unique to California (an argument adduced by the Bush administration’s EPA when it denied California’s waiver request in 2007, earlier post ); and.

Emissions from transportation sources were relatively constant from 2002 through 2007, declined through 2013, then increased by 9.0 The transportation sector represents tailpipe emissions from on-road vehicles and direct emissions from other off-road mobile sources. It does not include emissions from petroleum refineries and oil production.
Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion.
