Ana Carneiro of Harrison High School in Tippecanoe County, Ind., conducts an experiment during activities at the 2013 Duke Energy Academy at Purdue. She will assist during this year's academy on the West Lafayette campus, June 22-28, before enrolling at Purdue this fall as a freshman planning to study chemical engineering.
In a ruling issued Monday, the U.S. Supreme Court says the Environmental Protection Agency has the authority to limit the amount of greenhouse gases companies can produce—but it can only do so if the company is already required to get permits for other pollutants. Environmentalists and state officials in Indiana are declaring the ruling a victory.
Indiana joined 12 several other states in suing the EPA, alleging its new standards regulating greenhouse gases overstepped the authority Congress had given it.
