Guardians of the ocean: How SIDS are leading the 1.5°C agenda and what the world must do next
By Shafraz Rasheed
Small Island Developing States (SIDS) are at the leading edge of the climate crisis. Threatened by rising sea levels, intensifying storms, and fragile marine ecosystems, these nations face existential risks to their economies, cultures, and ways of life. However, the vast oceans surrounding them offer more than just vulnerability they hold the key to resilience and global climate leadership.
The ocean is not only a victim of climate change; it also plays a vital part in the solution. When approached sustainably, the "blue economy" can enhance climate resilience, reduce emissions, and sustain livelihoods in SIDS. The real challenge lies in unlocking this potential amid growing environmental threats and limited resources.
The Blue Economy: Beyond Resource Extraction
For many SIDS, the ocean is central to their territory and economic sustainability. Fisheries, tourism, shipping, and marine biodiversity are essential for development and food security. However, overexploitation, pollution, coral degradation, and uncontrolled coastal development have driven marine ecosystems to the edge.
A sustainable blue economy prioritizes responsible utilization of the ocean to drive economic growth, social equity, and environmental conservation. Restoring mangroves and coral reefs, expanding marine protected areas, and promoting sustainable aquaculture represent nature-based solutions that capture carbon, safeguard biodiversity, and create jobs. U.N. Trade and Development (UNCTAD) states that climate initiatives based on oceans could provide more than 20% of the required emissions reductions by 2050 to restrict global warming to 1.5°C. SIDS are uniquely situated to lead this shift, but they require financial support, technology transfer, and equitable market access.
Toward Ocean-Positive Development
The United Nations Development Program's (UNDP's) "ocean-positive" development approach requires a fundamental shift in perspective. Instead of perceiving the ocean solely as a resource to exploit or a delicate ecosystem to protect, this approach combines climate initiatives, economic resilience, and social advancement.
This demands a recalibration of global policies from the World Trade Organization to COP (the decision-making body of the U.N. Framework Convention on Climate Change)to prioritize ocean health as an indicator of climate progress. For island nations, it includes expanding ocean-based renewable energy sources (such as offshore wind and tidal energy), creating marine-sector jobs for women and youth, and building climate-resilient infrastructure. Initiatives like the Ocean Risk and Resilience Action Alliance (ORRAA) bring together public and private stakeholders to finance coastal resilience through blue bonds, insurance schemes, and blended finance.
Innovative Solutions: Solar-Powered Mobility
A recent article from Japan Times (June 2025) highlights an emerging breakthrough: solar electric vehicles (solar EVs). These self-charging vehicles, equipped with solar panels, provide eco-friendly, cost-effective transit perfect for island environments.
Solar EVs offer a compelling solution for SIDS, many of which face high transport emissions and dependence on fossil fuel imports. These vehicles are already being piloted in island nations, especially in marine tourism zones and port cities. Solar ferries and marine logistics systems powered by microgrids are also being tested, complementing wider efforts to decarbonize transport and strengthen energy independence.
When integrated with blue economy initiatives, solar mobility systems reduce emissions, support sustainable tourism, and create new jobs in the green tech sector.
From Vulnerability to Visionary Leadership
Despite their size, SIDS have played a significant role in international climate diplomacy. They championed the 1.5°C target in the Paris Agreement, advocated for ocean conservation in U.N. forums, and pioneered financial instruments such as Seychelles' Blue Bond and Fiji's Green Bond.
The Maldives is phasing out single-use plastics and adopting nature-based coastal protections. Samoa is investing in sustainable fisheries and renewable energy. Through alliances like AOSIS, Caribbean and Pacific nations are promoting climate-smart marine policies. These efforts prove that with appropriate assistance, small islands can become hubs of innovation and resilience, offering lessons for coastal areas globally.
What the World Must Do Next
To unlock the full potential of SIDS in leading the ocean and climate agenda, the global community must act decisively. First, climate finance must become more accessible, predictable, and tailored to island contexts through simplified procedures, concessional loans, and public-private investment models. Second, innovation must be fast-tracked in key areas including solar EVs, blue energy, sustainable fisheries, and ocean carbon markets.
Third, ecosystems must be protected and restored through expanded marine protected areas, habitat conservation, and stricter anti-pollution and anti-overfishing measures. Fourth, trade systems must be reformed to ensure SIDS gain fair value for their marine exports and can build resilient, inclusive economies.
Finally, stronger regional governance, maritime monitoring, and policy coordination will help secure the ocean commons for future generations.
SIDS are more than climate victims. They are visionary leaders showing the world how to build a just, sustainable future rooted in ocean stewardship and resilience. Their success is our shared success. If we want to safeguard the planet, we must start by standing with its smallest defenders who are proving to be among its strongest.

Japan's FY2023 greenhouse gas emissions hit record low for 2nd year
Japan's greenhouse gas emissions fell to a record low in fiscal 2023 for the second straight year on the back of reduced manufacturing activity and a greater share for renewable and nuclear energy in power generation, the government said. National emissions in the year through March 2024 totaled 1.07 billion tons of carbon dioxide equivalent, down 4 percent from fiscal 2022 and marking the lowest level since comparable data became available in fiscal 1990. The decline was mainly attributable to renewable and nuclear energy accounting for over 30 percent of Japan's power generation and lower energy consumption and industrial production, Environment Ministry officials said. Japan has set a goal of net-zero greenhouse gas emissions by 2050 by subtracting CO2 absorption by forests, aiming to reduce emissions by 60 percent in fiscal 2035 and 73 percent in fiscal 2040, compared with fiscal 2013. Emissions in fiscal 2023 marked a 27.1 percent drop from fiscal 2013, with officials saying the country is on track to achieve the goal. In fiscal 2023, emissions fell 4.0 percent from fiscal 2022 in the manufacturing sector, while household emissions were down 6.8 percent, likely due to a warmer winter. "Emission reduction is on the right track but only halfway through," Environment Minister Keiichiro Asao said in a press conference, stressing the need for continued efforts by both the public and the private sectors. The ministry reported the emission data to the secretariat of the U.N. Framework Convention on Climate Change. © KYODO

Plastics failure is a canary in the climate coal mine
You might have missed it amid the noise of the Trump transition and the sound of the European and Japanese auto industries collapsing. But the failure of an obscure United Nations meeting in South Korea at the weekend is a sign of how the entire edifice of environmental diplomacy is creaking. The meeting in the port city of Busan was intended to hammer out the text of a treaty to prevent plastic pollution, ahead of a planned summit to formalize the agreement next year. It would then join existing U.N. conventions on biodiversity and the ozone layer — along with by far the most well-known such institution, the U.N. Framework Convention on Climate Change, or UNFCCC. It's common to treat these meetings as meaningless talking shops, but that's not right. We have already measurably slowed global warming and prevented millions of cancer deaths thanks to the 1987 Montreal Protocol on ozone-depleting chemicals. Policies enacted under the UNFCCC helped push carbon emissions about 12% below the direction they were headed in 15 years ago.
