Black carbon (BC) from incomplete biomass and fossil fuel combustion is the most strongly light-absorbing component of particulate matter (PM) air pollution and a major climate-forcing emission. Air pollution mitigation efforts focusing on reducing combustion pollution are likely to have major benefits for climate and human health.
For a battery EV, 46% of its total carbon footprint is generated at the factory, before it has travelled a single mile. The study found that some of the CO 2 savings made during the use of low carbon vehicles is offset by increased emissions created during their production, and to a lesser extent, disposal.
