The Philippines aspires for a clean energy future but has become increasingly reliant on imported fossil fuels due to rising energy demands. Despite renewable energy targets and a coal moratorium, emissions reductions have yet to materialize. This study evaluates the potential of offshore wind (floating and fixed), floating solar PV, in-stream tidal, and nuclear power to contribute to a Net-Zero energy plan for the Philippines, utilizing the Open-Source Energy Modelling System (OSeMOSYS). Seven scenarios were analyzed, including least-cost, renewable energy targets; Net-Zero emissions; and variations in offshore wind growth and nuclear power integration. Floating solar PV and offshore wind emerged as key decarbonization technologies, with uptake in all scenarios. Achieving Net-Zero CO₂ emissions by 2050 proved technically feasible but requires substantial capital, particularly after 2037. Current renewable energy targets are inadequate to induce emissions reductions; and a higher target of ~42% by 2035 was found to be more cost-effective. The addition of nuclear power showed limited cost and emissions benefits. Emissions reductions were projected to mainly occur after 2038, highlighting the need for more immediate policy action. Recommendations include setting a higher renewables target, offshore wind capacity goals, a roadmap for floating solar PV, and better incentives for private investment in renewables and electric transport.

This best practice brief presents Component 6 of the Data-to-Deal (D2D) framework, which addresses how to strengthen the enabling environment for investment. This component focuses on the coherent policy, regulatory, and institutional reforms needed to reduce risk, create clear routes to market, and build investor confidence in clean energy and sustainable transport systems. Stable legal frameworks, predictable pricing and incentive structures, and transparent procurement processes are essential to mobilise capital at scale. Component 6 on successful enabling environments comprises three sub-components: (i) operationalising cross-cutting enablers; (ii) identifying and designing policy reforms; and (iii) developing an implementation plan to prioritise and sequence reforms. These sub-components are embedded across the D2D pipeline, linking political commitment, technical planning, and finance mobilisation into a coherent reform agenda. The brief draws on case studies from Zambia, South Africa, and the UK to illustrate how targeted reforms can expand renewable energy, reduce costs, and create investor-ready markets, while also highlighting the role of domestic capital market reforms in unlocking long-term sustainable financing. By operationalising this approach, countries can develop integrated, context-specific reform packages that advance development priorities, meet climate commitments, and strengthen resilience.
