Nigeria’s NDC proposes to reduce 20% of its GHG emissions relative to BAU scenario by 2030 unconditional of external help and 45% conditional on international support. The baseline year for the BAU projections is 2018, with an estimated 347 MtCO2e emission. According to updated GHG projections, Nigeria recalculated the amount of GHG emissions projected to 2030, estimating in this updated NDC a total of 453 MtCO2e in 2030 rather than the 898 MtCO2e estimated in the INDC. The NDC emissions reduction strategy includes CO2, CH4, N2O, HFCs, black carbon and air pollutant gases.
