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.

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. Pollutants other than ammonia should probably be targeted for abatement, Paulot said.

Port of Los Angeles surpasses 2023 pollution reduction targets five years ahead of schedule; NOx down 60% from 2005

Green Car Congress

Using this type of measurement, the Port also posted its best year ever, lowering the average amount of emissions the port generates to move each container of cargo for all eight pollutants tracked by the Port’s emissions inventory, including greenhouse gases (GHG), which were down 30% per container on average since 2005.

CMU study finds that coal retirement is needed for EVs to reduce air pollution

Green Car Congress

Life cycle emissions by pollutant and life cycle stage for each vehicle type in the recent (a) and future (b) PJM grid. They then modeled the emissions from those power plants, the effects of emissions on air pollution in downwind counties, and the resulting implications for human health and the environment.

Large-scale study associates even brief exposure to PM2.5 with childhood lung infections

Green Car Congress

The most important finding of this study is that infectious processes of respiratory disease may be influenced by particulate matter pollution at various levels. Dr. Horne and colleagues studied 146,397 individuals who were treated for ALRI between 1999 and 2016 at Intermountain Healthcare facilities throughout Utah’s Wasatch Front region.

Euro Parliament committee approves new 95 g/km CO2 target for cars; super credits and a switch to WLTP

Green Car Congress

The environment committee of the European Parliament approved a draft law setting out a new CO 2 target for cars of 95g CO 2 /km (153 g/mile) by 2020, down from 130 gCO 2 /km (209 g/mile) in 2015. The draft also sets indicative targets for post-2020 CO 2 emissions in the range of 68-78 g/km (109-126 g/mile) from 2025.
