Carbon dioxide and other greenhouse gases can be regulated at various stage of their production: “upstream” (when the carbon material is first produced, such as mining coal and other fossil fuels) or “downstream” (when the fuels are burned and CO2 is actually emitted).

There can also be a hybrid system: some emissions can be regulated upstream, and others downstream. However, such a system would be more difficult to administer, and could lead to double-counting of some emissions.
