Facts4Paris: 79% of post-2011 carbon budget all used up by 2030.
For a likely (66%) chance of staying below 2°C of warming, we can only afford another 1000 GtCO2 cumulative carbon emissions after 2011. If INDCs are not augmented, we will have exhausted about 580 GtCO2 of those 1000 GtCO2 by 2025 and 790 GtCO2 by 2030. For a 1.5C carbon buget of 550 GtCO2, the current INDCs will exhaust that by 2025.
