不允许以碳作能源的发电厂释放二氧化碳气体，对二氧化碳气体作妥善处理。 节约使用能源，比如改用混合型汽车和卡车。
There are at least three options: shift to non-carbon energy sources such as solar or nuclear energy; capture and dispose of the carbon dioxide emitted at carbon-based power plants; economize on energy use, for example by shifting to hybrid automobiles and trucks.
