A new report by the American Lung Association puts Missouri near the bottom of the list when it comes to state tobacco control policies.

Missouri was one of six states to receive an “F” grade in all four categories.

Power plants are the largest emitters of greenhouse gases in the U.S., followed by petroleum refineries.

That's according to data released today by the U.S. Environmental Protection Agency.

The data set shows 2010 emissions of carbon dioxide, methane, and other greenhouse gases from more than 6,700 of the largest sources in the U.S., including large industrial facilities and suppliers of certain fossil fuels and industrial gases.
