SACRAMENTO, Calif. —California regulators on Thursday approved the first system in the nation to give polluting companies such as utilities and refineries financial incentives to emit fewer greenhouse gases.
The Air Resources Board voted 9-1 to pass the key piece of California's 2006 climate law with the hope that other states will follow the lead of the world's eighth largest economy.
Here's how it would broadly work:
A company that produces pollution, such as a utility or a refinery, buys a permit from the state that allows it to send a specified amount of carbon dioxide and other greenhouse gases into the air each year.
Those permits could then be bought and sold by the polluters in a marketplace.
Animal-euthanasia drug used in execution
McALESTER, Okla. —Oklahoma officials executed a convicted murderer Thursday using a drug combination that includes a sedative commonly used to euthanize animals, after a nationwide shortage of a key ingredient forced the state to tinker with the usual formula.
John David Duty was pronounced dead at 6:18 p.m. at the Oklahoma State Penitentiary. The 58-year-old, who was sentenced to die for strangling his cellmate nearly a decade ago, is believed to be the first person in the United States whose execution included the use of pentobarbital.
The lethal drugs began to flow at 6:12 p.m., and Duty's breathing became labored one minute later. At 6:15 p.m., he appeared to stop breathing and the color began to drain from his face.
