Tonga plays a leading role in environmental protection in the Pacific, with strong commitments to sustainability and climate resilience. 

As one of the world’s lowest greenhouse gas emitters, Tonga has designated 13.3% of its terrestrial territory as protected areas, significantly surpassing the Pacific Islands average of 4.09% (2024). The country aims to generate 70% of its electricity from renewable sources by 2030 and is a vocal advocate in global climate forums such as the UNFCCC and AOSIS. Tonga also participates in major initiatives like the Green Climate Fund and the Pilot Program for Climate Resilience, securing international support to strengthen disaster preparedness and build climate-resilient infrastructure. This leadership positions Tonga as a reliable and forward-looking partner in green growth.
