Validation was done with data from 2005-2014. Details on the methodology used can be found at BAU emission in target year 2025:13,443 kT CO2 eq Mitigation scenario emissions in target year Unconditional contribution 7.8% below BAU by 2030 Conditional contribution contingent on international support: 10% below BAU by 2030 2 The energy sector is defined in accordance with IPCC guidelines, and includes the transportation sector.3.1 Choice of base year The year 2005 was the last year for which a complete inventory of Jamaicaâs GHG emissions exists. 3.2 Fairness and Ambition As modelled, Jamaicaâs INDC will result in emissions of the equivalent of 4.7 metric tons of carbon dioxide per person by 2030 (versus the equivalent of 5.1 metric tonsof carbon dioxide per person under the BAU scenario).
