EPA trends report finds MY 2021 fuel economy remained flat at a record high while CO2 levels hit new low

Green Car Congress

The US Environmental Protection Agency (EPA) released its annual Automotive Trends Report , which shows that model year (MY) 2021 vehicle fuel economy remained at a record high—but flat with MY 2020 fuel economy—while CO 2 emission levels reached a new record low. Estimated real-world fuel economy and CO 2 emissions.

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.

NASA Glenn develops automated flywheel pulse-and-glide system; improving fuel economy up to 40-100%

Green Car Congress

Innovators at NASA’s Glenn Research Center have developed an automated pulse-and-glide technique using a flywheel energy storage system for on-road vehicles; the technology, which NASA Glenn says can improve fuel economy over existing internal combustion or battery hybrid systems by 40-100%, is available for licensing. and Lohse-Busch, H.
