California introduces first-in-nation rules to reduce climate “super pollutants” from commercial refrigeration, air conditioning equipment

Green Car Congress

HFCs are synthetic gases that are used in a variety of applications, but mainly to replace ozone-depleting substances in aerosols, foams, refrigeration and air-conditioning. The California Air Resources Board recently approved first-in-the-nation rules to curb the impact of hydrofluorocarbon (HFC) refrigerants.

UCL-led study finds climate impact caused by growing space industry needs urgent mitigation

Green Car Congress

The rapidly growing space industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study led by UCL and published in the journal Earth’s Future as an open-access paper. The space industry is one of the world’s fastest growing sectors.

MIT study: half of US deaths related to air pollution are linked to out-of-state emissions

Green Car Congress

The study focuses on the period between 2005 and 2018 and tracks combustion emissions of various polluting compounds from various sectors, looking at every state in the contiguous United States, from season to season and year to year. Scientists have long known that pollution observes no boundaries, one of the prime examples being acid rain.

Study Links Springtime Ozone Increases Above Western North America to Emissions in Asia

Green Car Congress

Springtime ozone distributions for 1984, 1995–2008 in the mid-troposphere (3.0–8.0 Springtime ozone levels above western North America are rising primarily due to air flowing eastward from the Pacific Ocean, a trend that is largest when the air originates in Asia. The US EPA recently proposed new tougher ground-level ozone standards.

California Air Resources Board posts revised draft of strategy to reduce “Super Pollutants”

Green Car Congress

The California Air Resources Board (CARB) has posted a revised draft of California’s proposed Short-Lived Climate Pollutant (SLCP) Strategy. SLCPs are a category of pollutants which remain in the atmosphere for a relatively brief period, but have global warming potentials that are much higher than those of CO 2. Black carbon.

Eaton introduces set of products to reduce vapor emissions during refueling; LEV III regulations

Green Car Congress

This leakage occurs in all gasoline-powered vehicles, including passenger cars and an increasing number of small- and mid-sized commercial vehicles. If fuel vapor is released into the atmosphere, it contributes to a category of pollutants known as evaporative emissions. Helps meet global emission regulations.

California ARB moves forward with climate and air quality actions

Green Car Congress

CARB also adopted a new plan to curb destructive “super pollutants” including black carbon, fluorinated gases and methane. The plan, California’s Short-lived Climate Pollutant Reduction Strategy, maps out the route to more rapid greenhouse gas reductions by clamping down on these super pollutants. emissions by more than 20%.
