TRUE US database shows emissions characteristics of US fleet

Green Car Congress

To complement its work on real-world emissions in Europe, TRUE has compiled remote sensing data from the states of Colorado and Virginia and the University of Denver to investigate the emissions of US light-duty vehicles. gNO x /kg per year) and light-duty trucks (0.08 Source: The ICCT. gNO x /kg per year).

Discovery of mechanism for atmospheric particle formation suggests need for ammonia emission regulations

Green Car Congress

An international team of researchers has shed light on one way new particles are forming in the upper troposphere. The presence of ammonia was first discovered in the upper troposphere in 2016 using the analysis of averaged MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) infrared limb-emission spectra.

Canada and California to work together on cleaner transportation

Green Car Congress

The transportation sector is the source of nearly a quarter of Canada’s carbon emissions and more than 40% of California’s. Canada is currently completing a mid-term review of its light duty vehicle regulations. Canada is developing a Clean Fuel Standard that will cut emissions by 30 million tonnes in 2030.

Study projects emission impacts of inexpensive, efficient EVs: 36% further reduction in LDV GHG by 2050, or 9% economy-wide

Green Car Congress

A new study by researchers at the University of Colorado at Boulder projects the emission impacts of the widespread introduction of inexpensive and efficient electric vehicles into the US light duty vehicle (LDV) sector. Total NO x , VOCs, and SO 2 emissions are similar in OPT and BAU due to inter-sectoral shifts.

Study finds pollution emitted near equator has biggest impact on global ozone

Green Car Congress

They found that the increase in ozone burden due to the spatial distribution change slightly exceeds the combined influences of the increased emission magnitude and global methane. Based on their findings, they suggested that emission increases in Southeast, East and South Asia may be most important for the ozone change.
