Note: The emission trajectories in this proposal do not correspond precisely on a year-by-year basis to the IPCC A1FI scenario described below. But total emissions for the 21st century in this proposal do approximate total emissions under A1FI, and as a result, key environmental impacts, such as temperature increase and damage to earth systems (as shown in the Physical impacts tab) are in line with those that could be expected under A1FI.

Executive summary

This proposal assumes continuation of current practices, with fossil fuels meeting most of the world's energy needs throughout the 21st century.

It is the approach of choice for those who are skeptical about climate change.

It is based on two key assumptions:
- fossil fuels will remain the most economical source of energy,
- future carbon dioxide (CO2) emissions will not cause significant damage.

Total emissions over the 21st century in this proposal approximate those in the Intergovernmental Plan on Climate Change (IPCC) A1FI scenario (though emission differ somewhat from A1FI on a year-by-year basis).

A1FI posits rapid future economic growth and a fossil fuel intensive energy system.
