Emissions of potent GHG HFC-23 have grown, contradicting reports of huge reductions

Green Car Congress

Despite reports that global emissions of the potent greenhouse gas, HFC-23, were almost eliminated in 2017, an international team of scientists, led by the University of Bristol, has found atmospheric levels growing at record values. As a result, they reported that they had almost completely eliminated HFC-23 emissions by 2017.

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. California is required to reduce HFC emissions 40% below 2013 levels by 2030 under Senate Bill 1383. This equipment often leaks refrigerants over time.

Study: surface ozone in India in 2005 damaged 6M tonnes of crops, enough to feed 94M people in poverty

Green Car Congress

Ozone, the main component of smog, is a plant-damaging pollutant formed by emissions from vehicles, cooking stoves and other sources. New research shows that ozone pollution damaged millions of tons of wheat, rice, soybean and cotton crops in India in 2005. Surface ozone pollution in India damaged 6 million metric tons (6.7

California ARB announces $24M grant solicitation for zero-emission truck and bus pilot commercial deployment projects

Green Car Congress

The California Air Resources Board (ARB) announced a grant solicitation for Zero-Emission Truck and Bus Pilot Commercial Deployment Projects. Medium- and heavy-duty on-road trucks and buses are a significant source of emissions of greenhouse gases (GHG); diesel particulate matter 2.5 emissions, and 5% of GHG emissions.
