The global targets are based on the IPCC carbon budgets documented in the Assumptions at the bottom of this page. There are no official targets but we have calculated what the targets would be if the limits for remaining around 1.5oC or under 2oC were followed, and using the known emissions for the years 2011 to 2015 and projected emissions from 2016 to 2020. Global targets are specified as Carbon Dioxide (CO2).
The following charts are an example of what global emission reductions need to be along with the cumulative emissions resulting from the suggested limits. These charts assume that emissions are reduced at the same rate each year. This is obviously not realistic and is a best-case scenario. There is a history of global emissions here.

The emission reduction targets for remaining around 1.5 or below 2 degrees C are in this table (compared to 2011 emissions).
Less than 2oC
What happens if we do not reduce our annual emissions?
