Study: surface ozone in India in 2005 damaged 6M tonnes of crops, enough to feed 94M people in poverty

Green Car Congress

Ozone, the main component of smog, is a plant-damaging pollutant formed by emissions from vehicles, cooking stoves and other sources. New research shows that ozone pollution damaged millions of tons of wheat, rice, soybean and cotton crops in India in 2005. Surface ozone pollution in India damaged 6 million metric tons (6.7

MECA emissions inventory & air quality modeling shows potential benefits of national cleaner trucks initiative at CARB limits

Green Car Congress

The base year was selected as 2028 and the modeled year of 2035 was chosen to allow seven years of phase-in of low NO x trucks meeting the future modeled CTI scenario emission limits while still providing adequate confidence from an air quality perspective. Later years should show additional improvements as greater fleet turnover occurs.

UNEP study: small number of measures targeting black carbon and tropospheric ozone could yield immediate climate benefits

Green Car Congress

Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Reducing black carbon and tropospheric ozone now will slow the rate of climate change within the first half of this century, the study said. Full implementation of these measures would reduce future global warming by 0.5 °C
