Emissions Prices and Reductions under Climate Stabilization Scenarios: Full Global Participation
|Atmospheric stabilization target, ppm CO2-e||Emissions price in 2020 (2005 US$ per tonne of CO2-e)a||Percent change in global CO2 emissions in 2020 relative to 2000||Percent change in global CO2 emissions in 2050 relative to 2000|
|450a, b||15-263||−67 to 31||−13 to –92|
|550b||4-52||−4 to 50||−67 to 52|
|650||3-20||30 to 57||−16 to 108|
Only a limited number of the models are able to solve for this case (even with overshooting) as it requires the development and wide-scale deployment of negative emission technologies.
Includes cases both with and without transitory overshooting of the long-term stabilization target. In the 650-ppm case, there is no overshooting.
