The opportunity ahead

The Climate Bonds CONNECT 2025 Global Conference brought the year’s CONNECT series to a close with a unifying message: the global transition to a sustainable economy is not a distant goal. It’s already underway, and it’s gaining speed.

Delivering that transition will demand unprecedented coordination between governments, investors, and industry, but the resources, the capital, and the solutions already exist. The challenge — and the opportunity — lies in aligning them to create a future that is both profitable and sustainable.

Gathering more than 200 investors, asset owners, and market leaders, the conference explored how the sustainable finance community can turn ambition into action, structuring the projects, frameworks, and partnerships needed to build a world fit for the generations to come.

What we learned at CONNECT 2025

1. Opportunity defines the decade. The transition to a sustainable economy is accelerating, and represents one of the greatest investment opportunities in modern history.
2. Capital is ready — it just needs to move in the right direction. Investors, sovereigns, and policymakers are all seeking credible pathways to mobilise capital toward ambitious and impactful projects.
3. Collaboration is the catalyst. From methane abatement to resilience investment, the sustainable finance community is working together to design solutions that deliver both financial returns and a sustainable future.

Opportunity and Optimism: Investor Confidence in Transition

Behind every discussion at CONNECT 2025 was a shared sense of momentum. The transition to a sustainable economy is not only essential, it’s investable. From policy to portfolios, markets are shifting to capture the economic and social value of the green transition. Investors are responding with confidence, viewing sustainability not as a trade-off, but as a driver of long-term stability and growth.

Renewables already dominate global investment. Ninety-three percent of new energy generation comes from renewables, driven by proactive policy and industry innovation. Kingsmill Bond, Energy Strategist at Ember, described the momentum behind this shift as the electrotech revolution: generating clean electricity through solar and wind, using it to power vehicles and heat buildings, and finding new applications through technologies such as heat pumps. As Bond put it, “A century of evolution is converging into a decade of revolution.”

Despite short-term volatility and political uncertainty, investor confidence in sustainable finance remains high. Speakers from BNP Paribas Asset Management, Man Group, BlackRock, and Federated Hermes highlighted continued inflows and oversubscription in green and sustainable bonds.

Capital is increasingly flowing toward sectors once considered too difficult to decarbonise — like steel, cement, and shipping,— as clearer frameworks and taxonomies guide investment. The emphasis now is on credibility: investors want better disclosure, measurable impact, and confidence that capital is supporting genuine transition.

The result is a market that is maturing, not retreating. Sustainable finance is becoming a long-term structural pillar of the global economy.The panelists made it clear that, despite the noise, the appetite for sustainable investment is stronger than ever.

Sovereign Leadership: Aligning Policy and Capital

With more than USD 65 trillion in outstanding sovereign debt, governments are central to global climate progress. The launch of Climate Bonds’ new report – Sovereign Transition: Unlocking the Investment Opportunity provided a framework for integrating transition objectives into fiscal planning and debt management.

Panelists from Australia and Denmark showed how national governments are putting ambition into action, directing capital to critical transition and resilience investments. As Magali Van Coppenolle, Climate Bonds’ Head of Policy, said, “sovereign transition plans aren’t a single document — they are a coordinated process bringing together many parts of the economy working in the same direction.”

Sovereign bonds are emerging as a test of national climate ambition and a powerful tool for aligning public finance with sustainable growth.

Building Resilient Economies

he day’s discussions reinforced that resilience is the next great frontier of sustainable finance. The launch of the Climate Bonds Resilience Taxonomy (CBRT) provides investors and issuers with a credible framework for adaptation finance across infrastructure, agriculture, health, and social systems.

Craig Davies, CEO of Cadlas, pointed to the first certified resilience bond — issued by the Tokyo Metropolitan Government — as proof that this framework can translate into practical projects. Yet the imbalance remains: for every pound spent on mitigation, roughly five pence goes toward resilience. Private finance has a vital role to play in correcting that gap, as emphasised by British International Investment, Impax Asset Management, and MetLife Investment Management.

The CBRT now anchors the growing market for adaptation finance, expanding the pipeline of investible, high-quality resilience projects worldwide.

New Frontiers: Methane, Minerals, and Market Innovation

CONNECT 2025 also turned its attention to emerging challenges that will define the next phase of the transition.

Methane Abatement

Methane remains one of the most powerful levers for near-term climate action. With more than 80 times the warming potential of CO₂, but a much shorter lifespan in the atmosphere, rapid methane reduction offers immediate climate benefits. Ana Diaz, Energy Transition Lead at Climate Bonds, emphasised that “there is no way to reach a 1.5°C pathway without dealing with methane emissions.” Ana led Climate Bonds' efforts with the Methane Finance Working Group, creating guidance for credible investment in methane abatement in the oil and gas industry. Most emissions can be cut with existing technologies by targeting leaks, venting, and flaring, and many can be done at no net cost, meaning that these efforts are some of the most impactful and immediate steps we can take for near-term climate action.

Reyes Tirado , Climate Bonds' Agri-food standards lead, highlighted that agriculture produces over a third of global methane emissions, yet is often overlooked because of its complexity. Climate Bonds’ criteria now cover both crop and livestock systems, offering clear guidance for financing lower-emission agricultural practices. In countries where rice and cattle dominate production, this framework provides a pathway to measurable change.

Critical Minerals

Bridget Boulle, Climate Bonds Principal Technical Advisor, framed mining as a dual challenge: sustaining the energy transition while managing environmental and social risks. The industries that required for the green transition require critical minerals. Through batteries, solar panels, and other green technologies, demand for lithium, copper, and cobalt is set to rise sharply — lithium alone could increase ninefold by 2040. While recycling will play a growing role, new mining will remain essential. The key, Bridget said, is ensuring that extraction is aligned with credible sustainability standards as we develop the industries necessary for the green transition.

The conversations at CONNECT 2025 made one thing clear: the future of finance is being written now — through every green bond issued, every sovereign plan launched, every partnership forged across sectors and borders.

The barrier is no longer capital, but coordination. The world has the tools, the technology, and the resources to deliver a credible transition. What’s needed is the will to connect them — to link short-term returns with long-term resilience, and to build systems where prosperity and sustainability reinforce each other.

That is the real opportunity before us.

"The global transition is a challenge, but it's also an opportunity," said Sean Kidney. "It's an opportunity for investors to secure long term stability, for industries to work more efficiently and sustainably, and for governments to create wealth for their citizens."

The capital is ready to move. The frameworks are in place. The collaboration is happening. What comes next is turning alignment into action and shaping the future we all want to live in.
