EPA proposes approval of new ozone plans for the two of the worst Air Quality Zones in US: California’s San Joaquin Valley and South Coast

Green Car Congress

US EPA Region 9 8-hour ozone trends, 1979-2000. The US Environmental Protection Agency (EPA) is proposing to approve the 8-hour ozone air quality plans—which include their attainment demonstrations, enforceable commitments and reductions from new technologies—for California’s San Joaquin Valley (SJV) and South Coast (SC) areas, two of the worst air quality areas left in the country. Children and the elderly are most impacted by ozone pollution.

Study Highlights the Importance of Considering Climate Effects of Non-CO2 Emissions from Transport in Mitigation Strategies and Policies

Green Car Congress

The radiative forcing affects of a reduction in non-CO 2 pollutants (dominated by ozone and black carbon) can outweigh CO 2 effects, depending on the replacement energy source, according to a multi-pollutant study by researchers from the NASA Goddard Institute for Space Studies and the Environmental Defense Fund that examined the impact of a 50% reduction in on-road transportation emissions.

ICCT study finds that transitioning to low-GWP MAC refrigerants in China could avoid up to US$150B in costs

Green Car Congress

A new study from the International Council on Clean Transportation (ICCT) assesses the feasibility, benefits, and costs of phasing out HFC-134a as the refrigerant in mobile air conditioning (MAC) systems in the Chinese LDV fleet, focusing on three alternatives with lower global warming potential (GWP) most likely to be adopted by automakers with a global supply chain: HFO-1234yf, HFC-152a, and CO 2.
