Originally planned for publication in March, the new proposed 2 GHG rule for medium- and heavy-duty vehicles will be delayed until June.

The proposal was sent for White House review on 27 March, according to EPA’s Regulatory Development and Retrospective Review Tracker.

The joint EPA-National Highway Traffic Safety Administration (NHTSA) proposed rule will address fuel-efficiency standards for medium- and heavy-duty on-highway vehicles for model years beyond 2018 but likely would not take effect before 2020, according to EPA. The Phase 2 rule will follow the first-ever greenhouse-gas emissions and fuel-efficiency standards issued in 2011.

Mr Tamm will play a key role in the Lightning Rod Legislative Issues session at NAFA’s 2015 Institute and Expo in Orlando, Florida. The session takes place on the morning of Thursday 16 April.

He will share the stage with NAFA's legislative counsel in Washington DC Patrick O'Connor, president of the firm Kent & O'Connor.

Mr Tamm, Fuel Economy Division Chief with Office of Rulemaking at NHTSA, leads the Fuel Economy Division, which is responsible for establishing Corporate Average Fuel Economy (CAFE) regulations for passenger cars, light-duty trucks and medium-duty passenger vehicles, and fuel efficiency regulations for medium- and heavy-duty commercial vehicles and work trucks. The division is also responsible for reviewing and approving manufacturer petitions for alternative CAFE standards, and implementing consumer information programs, including regulations for some content on the fuel economy label and new regulations for alternative fuel badges on light-duty vehicles.

NAFA’s 2015 Institute & Expo, which takes place 14-17 April at the Orange County Convention Center, will see fleet professionals from throughout the world attend to learn about the latest technologies, best practices, and industry trends from over 60 hours of fleet educational sessions.
