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 limits would be if the limits for remaining under 1.5oC or 2oC were followed, and using the known emissions for the years 2011 to 2015. Global targets are specified as either Carbon (C) or 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. They are examples of what global emission reductions need to be. We have included charts of 80% of 1990 levels (22,300 MtCO2) by 2050 for comparison (4,460 MtCO2 per annum). 1990 was the year that targets (for developed countries) in the Kyoto Protocol were based on.

Both charts include suggested targets of 80% of 1990 emissions by 2050
The emission reduction targets for remaining below 1.5 or 2 degrees C are in this table (compared to 2011 emissions).
Less than 1.5oC
Less than 2oC
80% of 1990 levels
What happens if we do not reduce our annual emissions?
