The recent oil spill in the Gulf of Mexico is influencing long-promised legislation to curb global warming.
The bill unveiled Wednesday by Senate Democrats allows states to veto decisions by other states to drill for oil off their coasts. Opposing states must be able to show they would be significantly affected by an oil spill.
The legislation also requires a federal study to see if states could be affected either economically or environmentally by a leak.
Under the bill, states that drill would keep nearly 40 percent of the money generated. Currently, states collect no royalties.
The bill also aims to cut carbon dioxide and other emissions by 17 percent and would tax large emitters like coal-fired plants.
No Senate Republicans support the legislation.
