NEW YORK (Reuters) - Global emissions of the main greenhouse gas carbon dioxide will jump more than 39 percent by 2030 without new policies and binding pacts to cut global warming pollution, the top U.S. energy forecast agency said on Wednesday. Nearly 200 nations are set to meet late this year in Copenhagen to hash out a new agreement to control greenhouse gases as the Kyoto Protocol expires in 2012.
U.S. President Barack Obama and leaders in both the House and Senate hope to regulate the gases with a cap and trade market in emissions.
Without new agreements to foster emerging technologies such as solar and wind power and burial of carbon dioxide underground, world emissions of the gas should hit 40.4 billion metric tons by 2030, up from 29 billion metric tons in 2006, said the Energy Information Administration, the independent statistics arm of the Department of Energy.
Many scientists say emissions of greenhouse gases must be cut 80 percent or more by 2050 to avoid heat waves and killer droughts from global warming.
