NDC Status

Tonga submitted its second NDC in December 2020.

Key highlights from the NDC
  • Tonga increased its ambition, compared to its first NDC, by defining and quantifying the targets, specifying measures and providing better communication and transparency methods.
  • Mitigation targets are quantified in energy, agriculture, forestry and other land use (AFOLU) and waste sectors. For the energy sector, the target is a 13% (16 Gg) reduction in greenhouse gas (GHG) emissions by 2030 compared to 2006. Within the AFOLU sector, it has set non-emission targets of establishing a forest inventory as a prerequisite to identify a GHG emission target for the 2025 NDC and planting one million trees by 2023. For the waste sector, it established a non-emission target of expanding the formal waste collection system as a prerequisite to identify a GHG emission target for the 2025 NDC.
  • Adaptation targets include 30% of the land in Tonga utilized for agroforestry or forestry by 2025, preventing any permanent loss of land to rising sea levels on Tonga’s four main islands, and maintenance of the existing stocks of fish and other marine species.
