Study finds significant slowdown in decrease of NOx emissions in US; implications for air quality management

Green Car Congress

NO x emissions have not been decreasing as expected in recent years (2011–2015) when comparing top-down estimates from satellites and surface NO 2 measurements to the trends predicted from the US Environmental Protection Agency’s emission inventory data, according to a new study by an international team of researchers.
