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. Older models don’t even have the emission-control features that newer ones do. To reduce emissions, diesel vehicles use filters that catch exhaust particles and other contaminants.

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. Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. National benefits of the CH 4 plus BC measures versus the reference scenario.

Analysis finds air-quality justification for CNG vehicle conversion in developing cities, despite negative climate impact

Green Car Congress

Impact pathway approach for modeling policy interventions in (a) air quality and (b) climate impacts. An analysis by a team in Bangladesh found large air quality and associated health benefits accruing to the residents of Dhaka (the capital of Bangladesh) as a result of the rapid conversion of the motor vehicle fleet to CNG.

2018 Environmental Performance Index: Air quality top public health threat

Green Car Congress

In general, high scorers exhibit long-standing commitments to protecting public health, preserving natural resources, and decoupling greenhouse gas (GHG) emissions from economic activity. India and Bangladesh come in near the bottom of the rankings, with Burundi, Democratic Republic of the Congo, and Nepal rounding out the bottom five.
