EPA finalizes Tier 3 fuel and emissions standards
March 03, 2014
The US Environmental Protection Agency (EPA) finalized its Tier 3 emission standards for gasoline sulfur content; evaporative emissions; and tailpipe emissions from passenger cars, light-duty trucks, medium-duty passenger vehicles, and some heavy-duty vehicles. EPA had issued the proposed standards last March. (Earlier post.)
The Tier 3 standards, which come into effect starting in 2017, consider the vehicle and its fuel as an integrated system. The gasoline sulfur standard will make emission control systems more effective for both existing and new vehicles, and will enable more stringent vehicle emissions standards since removing sulfur allows the vehicle’s catalyst to work more efficiently. The Tier 3 standards are also closely coordinated with California’s LEV III standards as well as with EPA’s and California’s programs for greenhouse gas (GHG) emissions from light-duty vehicles.
World Bank to focus on reducing short-lived climate pollutants; transport projects

A new report prepared by the World Bank at the request of the G8 identifies ways that the World Bank can do more through its projects to reduce the emission of short-lived climate pollutants (SLCPs): black carbon, methane, tropospheric ozone, and fluorinated gases known as HFCs.
The review, “Integration of Short-Lived Climate Pollutants in World Bank Activities,” highlights ways the Bank’s investments are already reducing SLCPs and shows where potential exists for even greater reduction. It discusses a wide range of SLCP-reducing activities, including:
