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.

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.

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.

Hadley Centre: Average 4 C Warming Could Happen Within a Human Lifetime, With Even Greater Warming in Many Regions

Green Car Congress

The conference, attended by 130 international scientists and policy specialists, is the first to consider the global consequences of climate change beyond 2 degrees Celsius (3.6 °F). This high emissions scenario is based on no action being taken to reduce greenhouse gas emissions significantly, starting in the next few years.

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.
