California ARB: GHG emissions fell below 1990 levels for first time in 2016; down 13% from 2004 peak; transportation emissions up 2%

Green Car Congress

The California Air Resources Board (CARB) announced that greenhouse gas emissions in California in 2016 fell below 1990 levels for the first time since emissions peaked in 2004—a reduction roughly equivalent to taking 12 million cars off the road or saving 6 billion gallons of gasoline a year.

Satellite study: livestock digestion released 70% more methane than oil and gas industry in 2004

Green Car Congress

Livestock were the single largest source of methane gas emissions in the United States in 2004, releasing 70% more into the atmosphere than the oil and gas industry as estimated by other inventories, according to a new study by a team from Harvard University, JPL/CalTech and UC Irvine. emission inventory used as a priori.

Study: air pollution may shorten telomeres in newbornsa sign of increased health risks

Green Car Congress

A study conducted before and after the 2004 closure of a coal-burning power plant in Tongliang, China, found that children born before the closure had shorter telomeres than those conceived and born after the plant stopped polluting the air. In May 2004, high levels of air pollution in Tongliang prompted the government to shut down.

Large scale epidemiological study associates PM2.5, NO2 pollution with kidney, bladder and colorectal cancer death

Green Car Congress

Air pollution is classified as carcinogenic to humans given its association with lung cancer, but there is little evidence for its association with cancer at other body sites. The results were similar in two-pollutant models including PM 2.5 and NO 2 and in three-pollutant models with O 3. μg/m 3 increase in exposure.

Canada publishes proposed regulations for criteria pollutants from locomotives

Green Car Congress

The Government of Canada has published proposed Locomotive Emissions Regulations in the Canada Gazette, Part I. This marks Canada’s first regulation of air pollutant emissions from locomotives. The emission standards set out in these proposed regulations will also align with those of the United States. of PM emissions.
