The US Environmental Protection Agency (EPA) proposed greenhouse gas (GHG) emissions standards for airplanes used in commercial aviation and large business jets. The new international Airplane CO 2 Emission Standards adopted by ICAO in 2017 are prescribed in ICAO Annex 16, Volume III titled, Aeroplane CO 2 Emissions.
for emissions-related violations affecting nearly 2,000 on-road and off-road diesel engines. Emission-related field fixes must be reviewed and approved by CARB to ensure they don’t increase emissions. These illegal modifications may increase emissions of toxic and smog-forming pollution both on and off our roads and highways.
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.
