ITF: measures to decrease road freight CO2 emissions

Green Car Congress

Moving goods by road consumes about 50% of all diesel produced; 80% of the global net increase in diesel use since 2000 comes from road freight. Ambitious fuel economy and CO 2 emission standards will help widespread deployment of these measures. It is critical that these standards include heavy freight trucks.

Study finds clear trend of increasing NOx with higher biodiesel blends with CARB diesel; NOx neutrality achieved by blending in renewable or GTL diesel

Green Car Congress

NO x emissions results of biodiesel, renewable, and GTL diesel fuel blends, and CARB diesel fuel for 2006 Cummins ISM. They also found that increasing renewable diesel (Neste Oil’s NExBTL) and gas-to-liquids (GTL) diesel blends showed NO x reductions with rising blend level. Credit: ACS, Hajbabaei et al.
