New report reveals air pollution could rise drastically; outlines roadmap to devise models to curb emissions

A new report by The Energy and Resources Institute (TERI), University of California, San Diego (UCSD) and the California Air Resources Board (CARB) says that if current trends of vehicle population, fuel and emission standards persist, PM 2.5 emissions will increase by a factor of three, and those of NOx will increase by a factor of five. The transport sector contributes about 15 to 50 per cent of PM 2.5 emissions in cities, and is a dominant contributor to NOx emissions, says the report.
