US and UK researchers report direct measurement of key atmospheric reactant; more rapid formation of secondary aerosols

Green Car Congress

Molecules called Criegee intermediates—carbonyl oxides—are important atmospheric reactants, but only indirect knowledge of their reaction kinetics has been available. Criegee radicals have been impossible to measure until this work carried out at the Advanced Light Source. Carl Percival. —Welz et al.

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

Green Car Congress

Among the findings of the report, “HFC-134a phase-out in the Chinese light-duty motor vehicle sector”, was that, considering the social cost of CO 2 e, up to 1 trillion RMB in costs (US$150 billion) required to address climate change could be avoided through 2050 by transitioning to low-GWP alternative MACs.

IPCC: GHG emissions accelerating despite mitigation efforts; major institutional and technological change required to keep the heat down

Green Car Congress

Decomposition of the decadal change in total global CO 2 emissions from fossil fuel combustion by four driving factors; population, income (GDP) per capita, energy intensity of GDP and carbon intensity of energy. However, the underlying estimates do not take into account economic benefits of reduced climate change.

Calif. ARB releases GHG scoping plan update; more ZEVs, “LEV IV”, MD and HD regulations; ZEV for trucks; more LCFS

Green Car Congress

Many of the strategies employed to reduce GHG emissions will also work to meet the national ambient air quality standard for ozone in 2032. Recommendations are based on technologies currently available or expected in the near term, and on planning and investment steps that can be taken now. —Draft Scoping Plan Update.
