(b) Mitigation With regard to mitigation, Burundi committed itself to a 23% reduction in greenhouse gas emissions by 2030 compared to the baseline scenario (BAU), corresponding to a 3% reduction (1,958 Gg CO2) under its unconditional target and a 20% reduction (14,897 Gg CO2) under its conditional target. According to the 2015 UNFCCC, the establishment of the BAU referred to assumptions relating to the growth of the national economy (GDP), population growth and the rate of electrification contained in the above-mentioned documents. Some of these documents and many others developed served as the basis for the establishment of the BAU of the 2020 UNFCCC.
