According to Tongaâs Third National Communication (TNC) to the United Nation Framework Convention Climate Change, Tonga emitted a total of 310.4 Gg of CO2-equivalent in 2006, with the Energy sector accounting for 39%, Agriculture, forestry and other land use (AFOLU) accounting for 61%, and Waste accounting for 0.3% of total GHG emissions. Taking into account its negligible emissions and limited resources, as well as the ongoing disruption and uncertainty brought about by the COVID-19 pandemic, Tongaâs second NDC is nevertheless ambitious and reflects the urgency of the Paris Agreement. Tongaâs targets for mitigation are as follows: x Energy: 13% (16 Gg) reduction in GHG emissions by 2030 compared to 2006 through a transition to 70% renewable electricity as well as energy efficiency measures.
