The Well Tempered approach to historic emissions & division of the carbon budget

The Blueprint makes transparent the different pathways to the temperature goal, providing a framework within which country emissions may be understood as shares of the global carbon budget, and therefore as contributions towards the common goal set out in Article 2 of the UNFCCC and of the Paris Agreement.

It does so on the basis of internationally accepted data, in particular the IPCC assessments of cumulative emissions of carbon dioxide (or ‘carbon budgets’) consistent with:

GREEN - LOW RISK OF NON-COMPLIANCE 50% likelihood of limiting warming to < 1.5˚C (Budget 1)
AMBER - MEDIUM RISK OF NON-COMPLIANCE 33% likelihood of limiting warming to < 1.5˚C (Budget 2)
RED - HIGH RISK OF NON-COMPLIANCE 66% likelihood of limiting warming to < 2˚C (Budget 3)

More specifically the Blueprint reveals (measured in metric tonnes of carbon):

The purposes of the framework are to provide: -

The methodology underpinning the Blueprint is intended to be transparent, objective and easily explicable, making it appropriate for use in policy-making and judicial proceedings. It draws the line between past and future at 2014, reflecting the fact that 2013 is the last year of authenticated CDIAC data for country emissions. The Blueprint will be updated as new data become available.
