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.

AQLI: new data reveals little progress globally in reducing air pollution over the last two decades

Green Car Congress

Nearly a quarter of the global population lives in four countries in South Asia that are among the world’s most polluted: Bangladesh, India, Nepal and Pakistan. High pollution across the entirety of Bangladesh makes it the most polluted country in the world. Particulate air pollution continues to cut global life expectancy by nearly two years as progress in some countries counterbalances worsening air quality in others, according to the Air Quality Life Index (AQLI).

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. Vehicle ownership in Bangladesh is small, which puts Bangladesh among the top five countries in the world in CNG penetration (?18% of the annual GDP of Bangladesh, “ and thus the air quality benefits are clearly large.”.
