Democratic presidential candidate Barack Obama on Monday proposed spending 150 billion U.S. dollars over 10 years on new clean-energy programs.
The programs include measures to reduce greenhouse gas emissions and to develop new energy sources.
Under the proposal, polluters should pay for every ton of carbon emissions they release.
The call is the central element of his version of a "cap-and- trade" system, a common feature in the greenhouse gas reduction proposal.
Under cap-and-trade plans, pollution rights would be auctioned, sold or given to businesses, which could then resell or trade them to other businesses that need to purchase additional pollution rights, the Los Angeles Times said in an earlier report.
A national cap would be imposed on the total carbon emissions.
Obama supports a mandatory reduction of carbon emissions to 1990 levels by 2020, and an 80-percent reduction below 1990 levels by 2050 -- the same cuts sought by California and more ambitious than the 50-percent reduction by 2050 targeted by European countries.
