New study shows a rapid increase of diesel-fueled backup generators across California

Green Car Congress

New research by economic and public policy consulting group M.Cubed finds a proliferation of backup generators across California, with nearly 90% being diesel-fueled, posing significant obstacles to achieving greenhouse gas reduction targets and driving nearly $136 million in annual health costs. Of these, 20,907 are diesel-fueled.

NUS researcher links air pollution to increased residential electricity demand

Green Car Congress

The results of the study were published in the Journal of the Association of Environmental and Resource Economists. The study, set in Singapore, suggests that better air quality will bring about climate co-benefits in reducing electricity generation via lower household demand, and thus mitigating carbon emissions.

Insight into benzene formation could help development of cleaner combustion engines

Green Car Congress

That insight could also help the car industry make cleaner combustion engines. The industrial processes behind crude oil refineries and the inner-workings of gas-powered combustion engines can emit PAHs, which can form into toxic air pollutants such as soot. Zhao et al. This work was supported by the DOE Office of Science.

Study finds farms a major source of fine-particulate air pollution

Green Car Congress

Emissions from farms outweigh all other human sources of fine-particulate air pollution in much of the United States, Europe, Russia and China, according a new study published in Geophysical Research Letters , a journal of the American Geophysical Union. A 2015 study in the journal Nature estimates they cause at least 3.3

As states continue to use less coal for electricity, driving electric vehicles becomes even cleaner

Green Car Congress

Battery electric vehicles are only as clean as the energy source used to generate the electricity that powers them. Natural gas. This brief study analyzes, for each individual state, the changes from 2018 to 2020 in the use of coal (one of the two most polluting energy sources) to generate electricity.

UCS report shows electric cars get even cleaner in 2018

Green Car Reports

Electric cars keep getting cleaner, despite efforts by the EPA and NHTSA to roll back pollution standards on cars and powerplants. That's the conclusion of the latest report from the Union of Concerned Scientists which annually measures the environmental impact of driving an electric car.

CMU study finds taxes on emissions would result in more rapid electrification by ridesharing companies

Green Car Congress

Ridesourcing vehicles’ high use intensity is economically attractive for electric vehicles, which typically have lower operating costs and higher capital costs than conventional vehicles. Air pollution is a classic case where free markets fail. —Bruchon et al.
