Washington State Passes Cutting-Edge Policies To Reduce Climate Pollution

CleanTechnica EVs

Decarbonizing utilities: Washington passed the first law in the United States that outlines a pathway for a combined gas and electricity utility to transition away from gas for all of its customers. Proposed by Puget Sound Energy, the bill allows the utility to merge electric and gas customers into a single rate.

Researchers present new explanation for the long-range transport of PAH pollutants

Green Car Congress

When airborne particles (green) form before PAHs adhere, both the pollutants and particles dissipate quickly, as shown in the top row. But when the particles form in the presence of pollutants, which is what likely happens in nature, the longer-lasting particles enable the long-range transport of the pollutants (bottom).

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

the distribution of black carbon in the atmosphere and determine its role in the climate system. Black carbon (BC) is the second largest man-made contributor to global warming and its influence on climate has been greatly underestimated, according to the first quantitative and comprehensive analysis of this pollutant’s climate impact.

Researchers say policies to curb short-lived climate pollutants could yield major health benefits; methane and black carbon

Green Car Congress

Methane and black carbon (soot) are the second- and third-most powerful climate-warming agents after carbon dioxide. They also contribute to air pollution that harms the health of billions of people worldwide and reduces agricultural yields. Lead author Drew T. Resources. Shindell, N. Borgford-Parnell, M. Haines, J.C.I. Leonard, V.

California and Mexico sign agreement to reduce GHGs

Green Car Congress

The agreement with Mexico follows similar agreements signed by California in 2013 with the governments of British Columbia and the states of Oregon and Washington and China’s National Development and Reform Commission—the first agreement of its kind on climate change between the commission and a subnational entity.

Study projects thermoelectric power in Europe and US vulnerable to climate change due to lower summer river flows and higher river water temperatures

Green Car Congress

A study published in Nature Climate Change suggests that thermoelectric power plants (i.e., nuclear and fossil-fueled generating units) in Europe and the United States are vulnerable to climate change due to the combined impacts of lower summer river flows and higher river water temperatures.
