What are RCPs?
‘Representative Concentration Pathways’ are the four greenhouse gas concentration projections used in the IPCC’s fifth assessment report: RCP 2.6, 4.5, 6 and 8.5. They cover a range of emissions scenarios.
RCP 8.5 is the most dire and what we would likely see from a ‘business as usual’ approach.
RCP 2.6 is the most ambitious, and would require strong and urgent action.
