Overall Objective

GGGI is working with Tonga to implement its NDC and build climate resilience through the review and update of the Tonga Energy Road Map and the preparation of a Low Emission Development Strategy (LEDS). GGGI will further work with the Tongan Government to identify and implement opportunities for inclusive, low carbon and resilient green growth in Tonga in the energy, transport, and green cities sectors.

The Kingdom of Tonga is a Small Island Developing State (SIDS) in the Pacific region that is vulnerable to the impacts of climate change, including cyclones, coral bleaching, and changing rainfall patterns.

Tonga is committed to building greater resilience to the increasing risks of climate change through sustainable development. The Kingdom’s Strategic Development Framework 2015-2025, and 2015 Nationally Determined Contribution (NDC) to the United Nations Framework Convention on Climate Change (UNFCCC), express a commitment to mitigate climate change and pursue inclusive and equitable economic growth. With a small export economy, risks to agriculture, including changing rainfall patterns, present a significant threat to Tonga’s economic development. While high cost of imported fossil fuel presents a constraint to energy use for economic growth.


Access to reliable and affordable clean energy is a key part of building Tonga’s resilience to climate change. The Tonga Energy Road Map 2010-2020 (TERM) highlights that, in 2000, 75 percent of Tonga’s energy supply was from imported petroleum fuels. In the power sector, grid supplied energy accounts for 98 percent of electricity, all of which was generated using diesel in 2000. While nearly 90 percent of households are connected to the grid, and in rural areas most households have been electrified using solar home systems and micro-grids, access to affordable electricity is an issue, particular due to Tonga’s reliance on imported fuels and the high upfront capital cost of switching to renewable energy sources.

Under the TERM and NDC, Tonga has committed to 50 percent renewable energy generation by 2020, with landfill gas, biomass, wind, and solar energy considered as sources. It is essential that Tonga moves away from reliance on fossil fuels, diversifies its energy generation options, and develops renewable energy resources. Since 2000, a series of grid-connected solar and wind energy projects have introduced a share of approximately 11 percent renewable electricity in the Tongan grid with plans for further solar, wind and storage technologies to continue to boost the share of renewables and reach the 50 percent renewable energy generation target by 2020. However, there still remains work to be done given Tonga is also looking to increase its ambition and commit to up to 75 percent renewable electricity generation by 2030.

GGGI is supporting Tonga to pursue inclusive green growth and build resilience to climate change with a focus on enhancing infrastructure, improving energy security, increasing renewable energy and energy efficiency technologies, including for the transport sector, and reducing dependence on fossil fuels.
