The levels of these non-fuel-derived gases will likely remain unchanged, even as more drivers transition from gas-powered to electric vehicles. Cars’ average carbon dioxide emissions have dropped by 25% since the early 2000s, according to the US Environmental Protection Agency (EPA), but this gas only accounts for part of the total.

APRIL 29, 2013

In its recently released Inventory of US Greenhouse Gas Emissions and Sinks: 1990 – 2011 ( earlier post ), the US Environmental Protection Agency (EPA) reported that methane (CH 4 ) emissions from the field production of natural gas have declined by 36% from 2007 to 2011 (from 83.1 a global warming potential of 21. Tg CO 2 eq) in 2011.

Source of data: US EPA (2019). NO x is a precursor for both ground level ozone and secondary PM 2.5 EPA is targeting implementation in the 2027 timeframe while CARB is focusing efforts on phasing in more stringent standards in 2024 and again in 2027 with the hope of aligning with EPA as a national standard.

Many school districts use diesel buses for fuel efficiency, but even diesel exhaust was classified as a known carcinogen to humans in 2012. The EPA is expecting to award at least another $500 million in funding under the 2023 CSB rebate program and a further $400 million via grant funding.

MAY 6, 2010

Testing is due to be complete next year, prompting the auto, oil and outdoor power equipment industries to urge the Environmental Protection Agency (EPA) to delay action on its proposal to allow higher levels of ethanol in gasoline until that testing is done. Exhaust emissions on vehicles aged on mid-level ethanol blends.

The SuperTruck projects incorporated a number of vehicle power demand technologies that accounted for about 56 to 74% of the total fuel consumption reductions, with 26 to 44% coming from engine efficiency improvements. These projects have brought together a wide variety of companies, the national laboratories, and universities.

Although real-world fuel economy improvements from GDI technology alone are close to 1.5%, they can reach 8% by downsizing and turbocharging the engine, which can be achieved on GDI engines without loss of power compared to PFI engines. The EPA GHG program is aimed at reducing tailpipe CO 2 emissions. —Saliba et al.
