ANNOUNCEMENTS
Pacific Island Nations (PINs) are navigating an unprecedented convergence of climate, energy, and financial challenges. Geographically small yet spread across vast oceanic territories, these nations are among the most vulnerable to climate change facing rising sea levels, intensifying cyclones, and saltwater intrusion. At the same time, they remain critically dependent on imported fossil fuels, with over 85% of electricity generation in countries like Kiribati, Solomon Islands, and Vanuatu still derived from diesel. This reliance not only results in electricity costs ranging from USD $0.30 to $0.70/kWh—some of the highest globally—but also exposes energy systems to extreme volatility and logistical fragility.
This thesis investigates the status and future pathways of energy transitions across ten Pacific Island Countries: Fiji, Tonga, Kiribati, Solomon Islands, Vanuatu, Tuvalu, Samoa, Palau, Papua New Guinea, and Marshall Islands. It combines LEAP-based scenario modelling, policy and regulatory assessment, life cycle impact analysis, and carbon finance evaluation to generate a multi-dimensional roadmap for clean energy deployment and climate resilience.
Quantitative simulations indicate that countries like Fiji, Samoa, and Tonga could achieve 70–80% renewable electricity penetration by 2035, reducing diesel imports by more than 40% and avoiding over 1.5 million tonnes of CO₂ emissions over a decade. However, the research finds a persistent gap between national targets—such as Net Zero or 100% RE by 2030 commitments—and actual deployment. This is largely attributed to institutional fragmentation, weak regulatory environments, and inadequate access to climate finance. Countries like Tuvalu and Kiribati are ranked lowest in transition readiness due to financial, technical, and policy capacity gaps, while Fiji and Samoa lead in grid resilience, institutional reform, and renewable deployment.
The thesis introduces a novel approach to carbon credit estimation, showing that transitioning to solar energy can generate up to 0.85 tCO₂e in avoided emissions per MWh, with a market value of $5–$30 per tonne. These credits represent a significant untapped financing stream for infrastructure investment and adaptation programs. Comparative case studies from Crete and the Faroe Islands demonstrate that remote territories can overcome geographic and scale limitations through decentralized systems, community energy ownership, and regulatory innovation.
The final policy roadmap calls for decentralized microgrids, battery storage systems, legal mandates for renewable procurement, end-of-life management for solar technologies, and regional climate finance pooling mechanisms. Above all, it emphasizes that for Pacific Island Nations, energy transition is not just about mitigation it is about infrastructure survival, fiscal sovereignty, and intergenerational justice in the face of escalating climate risk.
