Assessing the direct public health impact of power-plant emissions reduction provides further support to the climate change regulation to be introduced by President Obama this summer, judging by a new study published this week in the journal Nature Climate Change. Cutting carbon emissions from the power sector 30 percent from 2005 levels by 2030 would reduce co-pollutants emitted by coal-fired plants such as soot and ozone, reducing instances of children asthma and preventing premature deaths. We like to think these findings by researchers at Syracuse and Harvard Universities can help grow public support for Obama’s upcoming policy.
