A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

Looking to make replacement filters more environmentally friendly and affordable, a team of engineering students from the Bangladesh University of Engineering and Technology , in Dhaka, designed a carbon-based version with bamboo. A carbon-based particulate filter Diesel engines produce more polluting particulate matter than gas engines.

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. Ozone, a key component of smog and also a greenhouse gas, damages crops and human health.

Low-lying and other vulnerable countries calling for fast action on non-CO2 global warming pollutants

Green Car Congress

The next round of UN climate negotiations begins in Cancun today. ” The authors go on to say that reducing the non-CO 2 pollutants can delay additional climate warming by several decades. Technology is already available to reduce these climate-forcing agents, and doing so would produce strong collateral benefits.

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.
