Carbon dioxide output rose by 80%.
Environmentalists propose reducing carbon dioxide output by building wind turbines.
Take the recent row over the Kyoto accord on cutting the world's carbon dioxide output.
Because the process consumes energy, it will raise the carbon dioxide output of refineries.
With existing targets, this is not likely before 2030, by when carbon dioxide output will have more than doubled.
Biodiesel can be made from soybeans or other biological sources, with much less carbon dioxide output per gallon.
Their total combined annual carbon dioxide output, although rising, accounts for less than 1% of global emissions.
Not very, according to a new study of carbon dioxide output in Japan in the months around the Fukushima disaster.
The agency said that reductions in the carbon dioxide output of the United States and China, the world's top two emitters, would be critical to stabilizing global emissions.
Mr. Prentice pointed to the deployment of carbon capture and storage, or C.C.S. — technologies that trap carbon dioxide output and store it underground — as a possible solution.
Carbon dioxide output fell by almost a tenth, as renewable energy generation rose to a new record high, accounting for nearly a fifth of electricity.
