CO 2 and NO x certification test data for heavy-duty diesel engines certified from 2002 through 2019. The transportation sector was responsible for over 7 million tons of NO x emissions in the US in 2014, with 50% of this sector’s NO x attributed to heavy-duty on- and off-road vehicles and equipment. Source of data: US EPA (2019).

A scatter plot of CO, as a tracer for pollution, versus CO 2 , as a tracer for the amount of combustion, for 2002 and 2010. Even though the CO 2 enhancements over background were comparable in the two years, about 25 ppm in 2002 and 35 ppm in 2010, the ?CO/?CO2 CO2 ratio for this flight track segment decreased from 24.5

From 2005 through 2020, total US greenhouse gas (GHG) emissions are projected to rise by 4% under a “with measures” scenario (but without a cap-and-trade program and other complementary policies), from 7,109 Tg CO 2 Eq. The report projects that transportation-related CO 2 emissions will drop 1.5% to 7,416 Tg CO 2 Eq., 5,813 Tg CO 2 Eq.

The California Air Resources Board released the draft proposed first update to the AB 32 Scoping Plan, which guides development and implementation of California’s greenhouse gas emission reduction programs. California’s zero emission vehicle (ZEV) regulation is also driving a transformation of the fleet.
