What to Watch in 2026: Our CEO’s Take

Patricia Fuller sits at a table and looks into the camera. There is a microphone and a nameplate labeled "IISD" on the table in front of her.

Although 2025 was a challenging year in the sustainability space, it still delivered on several key milestones.

But as governments confront rising misinformation, constrained budgets, and intensifying climate risks, the need for evidence-based policy has never been greater. Our president and CEO, Patricia Fuller, outlines the opportunities and challenges that will shape sustainable development in 2026.

With funding tightening, both in developmental assistance and the sustainability space more broadly, Patricia knows that think tanks must show where they create the greatest leverage. "Helping governments design strong, durable policy frameworks has one of the highest multiplier effects of any investment in sustainable development," she explains.

But despite this, there's still reason for hope: "A sustainable future is eminently possible, but it requires a healthier political and information ecosystem to get us there," she explains.

One reason behind her outlook is the reality of sustainable development: "The economics of the energy transition—they’re moving faster than politics," she explains, adding, "There’s also great promise in nature-based solutions. Our own work shows they deliver multiple wins at once—climate adaptation, healthier ecosystems, and stronger local economies."

How Cape Town Boosted Funding for Restoring Waterways

When funding for the City of Cape Town's waterway restoration projects was under pressure, the Nature-Based Infrastructure (NBI) Centre supported the city through two integrated cost–benefit analyses. By translating the environmental, social, and economic benefits of NBI into clear evidence, the analyses helped strengthen the investment case, moving projects toward implementation.

Sea Level Rise and the Law of Shared Responsibility 

"Sea level rise is one of the clearest and most devastating expressions of the climate crisis. For low-lying nations, it is not an abstract projection but an encroaching physical reality," write Catherine Amirfar and Duncan Pickard, two lawyers who helped Tuvalu present arguments to the International Court of Justice’s climate hearings.

Restoring Wetlands and Weaving Tradition: How Fijian coastal communities are building climate resilience
