With appropriate international assistance, Kiribati can reduce its emissions by more than 60% (61.8%) by 2030. Reference year or period The BaU projection is based on an extrapolation of historic data covering the period 2000-2014. Estimated, quantified emissions impact In addition to the carbon storage in the ocean ecosystem, Kiribatiâs unconditional contribution will reduce emissions by 10,090tCO2 e annually throughout the period 2020 to 2030.
