In a stunning move the Environmental Protection Agency (EPA) published a finding that carbon dioxide and other greenhouse gases constitute a danger to public health and welfare and are subject to regulation under the Clean Air Act.

With this historic decision it is now possible to regulate the amount of carbon released by industries in America. As the law specifically states that EPA “shall” (i.e. must, not may) regulate dangerous pollutants once they are found to endanger public health or welfare.

This is a very strong and definite warning towards industries which expel large quantities of carbon dioxide, or other greenhouse gasses. With a move like this I suspect that investments in, for example, coal fired power plants will slow down or stop.

Thank you president Obama on holding yourself to your promises to show leadership on global warming.
