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

Green Car Congress

The California Air Resources Board recently approved first-in-the-nation rules to curb the impact of hydrofluorocarbon (HFC) refrigerants. HFCs are considered to be super pollutants because they trap heat in the atmosphere thousands of times more effectively than carbon dioxide, the most prevalent greenhouse gas.

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.

International travelers experience adverse cardiopulmonary health effects even after short stay in polluted cities

Green Car Congress

For travelers who visit cities with high levels of air pollution, even a short stay leads to breathing problems that can take at least a week from which to recove, a new study led by researchers at NYU School of Medicine finds. Researchers then compared the health data against levels of air pollution collected from local government agencies.

T&E: tests show cars powered by electrofuels emit high levels of criteria pollutants

Green Car Congress

Proponents claim that if renewable electricity is used and CO 2 is captured from the air, then the e-gasoline and e-diesel are climate-neutral fuels that will also reduce pollution. However, said T&E, particle pollution was far from eliminated. pollution. The emissions were compared to the standard E10 EU gasoline. Full report.
