    "additionalInfo": "Data denotes the range of CO2 mitigation curves for a range of 'start year scenarios': scenarios are based on the annual emission reductions necessary to keep global temperature rise below 1.5C if emissions mitigation was to start in a given year. \n\nFor example, 'Start in 2010' marks the necessary future emissions pathway to have a >66% chance of keeping global average temperatures below 1.5C warming if global CO2 emissions mitigation had started in 2010, very quickly peaking then falling. \n\nData is sourced from Robbie Andrew, and available for download here: http://folk.uio.no/roberan/t/global_mitigation_curves.shtml\n\nHistorical emissions to 2017 are sourced from CDIAC/Global Carbon Project, projection to 2018 from Global Carbon Project (Le Qu\u00e9r\u00e9 et al. 2018).\n\nGlobal cumulative CO2 emissions budgets are from the IPCC Special Report on 1.5\u00b0C (Rogelj et al 2018): 420 GtCO2 for a 66% of 1.5\u00b0C and 1170 GtCO2 for a 66% of 2\u00b0C. Mitigation curves describe approximately exponential decay pathways such that the quota is never exceeded (see Raupach et al., 2014).",
