Ice core data show why air pollution is dropping more slowly in US and Western Europe despite lower sulfur emissions

Green Car Congress

This makes conversion of sulfur dioxide to sulfate more efficient. We need to understand this multiphase chemistry in the atmosphere to design an efficient strategy to manage air pollution and accurately predict future air pollution and climate change impacts.

Heat Pumps—The Well-Tempered Future of A/Cs

Cars That Think

Department of Energy tightened efficiency testing standards for air conditioners for the first time since 2015. As a result, air conditioner manufacturers are probably more interested in keeping up with global demand than in developing expensive, potentially disruptive climate-impact improvements. This year, the U.S. Still, in the U.S.,

Greyrock, NREL study determines reduction in GHG and criteria pollutant emissions from using synthetic fuels produced from flare gas

Green Car Congress

A Greyrock Flare Gas-to-Fuels conversion process at an Ohio oil well was used as the base case for this LCA. for hydrocarbons, particulate matter, carbon monoxide, and nitrogen oxides from 1996 to 2015 diesel vehicles. These clean mobility solutions may be realized without any changes to existing automotive infrastructure.

Lifecycle study finds fuel switching from diesel to natural gas could produce net climate damage absent reductions in CH4 emissions and improved vehicle efficiency

Green Car Congress

Otherwise, fuel switching can produce net climate damages (more radiative forcing) for decades. since natural gas has relatively low carbon intensity, releasing less carbon dioxide (CO 2 ) per unit of usable energy than other fossil fuels, it is often assumed that switching to natural gas is comparatively beneficial for the climate.
