A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

Although the pollutant emissions of a diesel engine are less than those of a gasoline one, it still emits carcinogens, nitrous oxides, and soot. A carbon-based particulate filter Diesel engines produce more polluting particulate matter than gas engines. Older models don’t even have the emission-control features that newer ones do.

International study identifies 14 key measures to reduce methane and black carbon emissions; reduction in projected global mean warming of ~0.5 °C by 2050

Green Car Congress

Circle areas are proportional to values for (A and B) climate change, (C and D) human health (values for population over age 30), and (E and F) agriculture. The team considered about 400 emission control measures to reduce these pollutants by using current technology and experience. Source: Shindell et al. Click to enlarge.

EPA report to Congress finds a strong scientific and technical foundation for mitigating black carbon emissions

Green Car Congress

The US Environmental Protection Agency (EPA) has submitted its final Report to Congress on Black Carbon , in response to an October 2009 request from Congress to advance efforts to understand the role of black carbon (BC) in climate change.

UN Environment report says national GHG pledges only bring one-third of reductions needed for Paris Agreement

Green Car Congress

The report also covers an assessment of the potential contribution from reductions in short-lived climate pollutants (SLCPs). This has raised hopes that emissions have peaked, as they must by 2020 to remain on a successful climate trajectory. These six present a combined poten al of up to 22 GtCO 2 e per annum.
