In July 2007, Florida Governor Charlie Crist announced plans to sign executive orders that would impose strict new air-pollution standards in the state, with aims to reduce greenhouse-gas emissions by 80 percent of 1990 levels by 2050. Crist's orders would set new emissions targets for power companies, automobiles and trucks, and toughen conservation goals for state agencies and require state-owned vehicles to use alternative fuels.[35] Governor Charlie Crist and both of Florida's senators, Bill Nelson and Mel Martinez, oppose offshore drilling and exploration. Former governor Jeb Bush, originally opposed to all drilling,[36] changed his position on a bill introduced into the House of Representatives in 2005, which would allow unrestricted drilling 125 miles (201 km) or more from the coast.[37] Martinez, Nelson, and Crist opposed that bill, but Martinez and Nelson voted for a Senate alternative which prohibited drilling within 125 miles (201 km) of the Panhandle coast, and 235 miles (378 km) of the peninsular coast.[38]
