Study finds CNG conversion policy in Bangladesh did result in more travel; congestion costs still half the health benefits

Green Car Congress

Several years ago, the government of Bangladesh took took various policies to convert the petroleum vehicles on road to run on compressed natural gas (CNG), which allows both air quality improvements and energy security benefits. In a 21013 study, researchers 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.

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

Green Car Congress

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. As the greenhouse gas impacts (costs or benefits) are much smaller than the health benefits, the conversion of petroleum vehicles to CNG can be justified on the basis of local air pollution benefits alone, they concluded.

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. Seven measures target CH 4 emissions, covering coal mining, oil and gas production, long-distance gas transmission, municipal waste and landfills, wastewater, livestock manure, and rice paddies. National benefits of the CH 4 plus BC measures versus the reference scenario.
