Massachusetts v. Environmental Protection Agency

This 2007 case laid the groundwork for future lawsuits forcing the EPA to enact stronger regulations.

Slides

In this case, Massachusetts and several other states sued the EPA to regulate carbon dioxide emissions and greenhouse gases. The 2007 Supreme Court Case found that the EPA can regulate greenhouse gases, such as carbon dioxide, as “air pollutants.” The Court also found that the states had standing to sue due to potential damage caused to their territory by global warming. This finding was a precursor to future lawsuits that demanded the EPA create stronger regulations.
