In
a move that paves the way for sweeping global-warming regulation, the
Environmental Protection Agency on Tuesday proposed requiring major U.S
industries to measure their greenhouse gas emissions.
The plan would affect large emitters of carbon dioxide
(CO2) and other greenhouse gases, such as oil refiners and automobile
manufacturers, as well as makers of cement, aluminum, glass and paper.
Power plants would be included, though they already must monitor how
much carbon dioxide they release under the Clean Air Act.
Under the rule, slated to be approved by year's end,
companies would start tracking their emissions next year. "It's a very
important step as we're moving forward to deal with climate change,"
says Dina Kruger, director of EPA's climate change division.
The proposal complies with legislation passed by Congress
in 2007. Yet David Doniger, a policy director for the Natural Resources
Defense Council, says the EPA's initiative is "another sign" President
Obama is intent on curbing global warming. The Bush administration, he
says, dragged its feet and withheld release of the proposed rule.
Congress is expected to consider climate-change legislation
this spring, though it's sure to be contentious as it would raise costs
for consumers during a brutal recession. A new law likely would place a
cap on CO2 emissions that would grow stricter over time. Companies that
exceed their limits could buy permits from those that fall below their
caps. Separately, the EPA itself could regulate emissions under a 2007
Supreme Court ruling.
