MIT study finds air quality co-benefits of US carbon policies can significantly offset costs, depending upon the policy

Green Car Congress

The human health benefits associated with improvements in air quality related to the reduction in greenhouse gas emissions improvements can offset 26–1,050% of the cost of US carbon policies, depending upon the type of policy, according to a new study by a team from MIT. Carbon-reduction policies significantly improve air quality.

EPA proposes new rules to reduce global warming HFC emissions from refrigerants

Green Car Congress

Specifically, the proposed rule updates the current prohibition under section 608 of the Clean Air Act against knowingly venting, releasing or disposing of ozone-depleting (ODS) and substitute refrigerants and extends the requirements, as appropriate, to non-ozone-depleting substitute refrigerants, such as hydrofluorocarbons (HFCs).

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

Green Car Congress

HFC-23 is a very potent greenhouse gas, with one tonne of its emissions being equivalent to the release of more than 12,000 tonnes of carbon dioxide. However, levels have been soaring because it is vented to the atmosphere during the production of another chemical widely used in cooling systems in developing countries.

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

Green Car Congress

SLCPs include black carbon (soot), methane and hydrofluorocarbons (HFCs)—the fastest-growing source of GHG emissions in California and globally—which are used as refrigerants, aerosol propellants and insulation. Black carbon. SLCPs may account for an estimated 40% of global warming, increasing the impacts of climate change.
