Global bang for the buck: Cutting black carbon and methane benefits both health and climate

摘要

Black carbon and methane have both been implicated in climate change. They also pose more direct human health threats, with black carbon constituting one component of fine particulate matter (PM_(2.5)) and methane acting as a precursor of ground-level ozone. An international team of researchers analyzed 14 control measures for human-caused emissions of black carbon and methane to investigate health benefits that might occur in tandem with actions to help mitigate climate change in the next 20-40 years [EHP 120(6):831-839; Anenbergetal.].
