Nationally Determined Contributions (NDC) Investment Roadmaps

The problem

Samoa and Tuvalu wanted to accelerate the implementation their Nationally Determined Contributions (NDCs) to global climate action under the Paris Agreement. Castalia was hired to develop investment roadmaps containing practical steps and tangible projects that aligned with each country’s NDC goals.

How we helped

Castalia evaluated emissions reduction and climate change adaptation opportunities across a range of sectors in each county. In consultation with the respective government ministries, we developed the most promising opportunities into project concept notes, estimated their costs and GHG emissions reduction potentials, and prioritized them in an investment pipeline using multicriteria analysis. We then included these investment pipelines within broader implementation roadmaps that set out practical steps and rigorous processes for achieving the objectives of each country’s NDC. In addition to helping officials plan to address climate change efficiently and effectively, these documents were designed to generate interest from potential partners, including donors and private investors.

Impact

The mitigation opportunities we identified in Samoa will potentially reduce national GHG emissions by 19 percent and enable investment needs of more than US$130 million. In Tuvalu, when combined with several major planned renewable energy investments, the projects we identified could reduce national GHG emissions by 55 percent. Samoa and Tuvalu are currently implementing these plans, which will guide their climate action efforts until 2030.
