Nature, Culture, Capital- Regenerating Economies & Re-imagining Cities Today
An Interactive Forum at London Climate Action Week 2025
This London Climate Action Week, join climate innovators, funders, policymakers, designers, and ecosystem builders as we collaborate to reimagine and regenerate two interconnected systems: nature and cities.
Curated by Concave, a Climate & Impact Investing Summit committed to building a net-positive future, in collaboration with Okhtapus, who will lead strategic matchmaking across a diverse and powerful network of innovators, funders, enablers, and ecosystem allies.
This forum is designed to accelerate collaboration and scale breakthrough climate solutions at the intersection of nature, cities, and systems change.
Why Now?
We’re at a tipping point. Climate action now demands radical collaboration—across sectors, disciplines, and geographies. Innovation alone isn’t enough. It’s time to connect nature, culture, technology, and finance in bold, regenerative ways.
Natural ecosystems and urban environments are deeply intertwined. To protect one, we must work across both. This is the moment to forge unlikely alliances—between startups, investors, enablers, policy makers, policy influencers, think tanks and academia.
Two Interconnected Focus Streams
🔹 Nature & Biodiversity
Explore regenerative bioeconomies and nature-based solutions spanning forests, farms, watersheds, and oceans. Discover scalable interventions that restore ecological health, strengthen rural livelihoods, and unlock finance for biodiversity.
🔹 Cities & the Built Environment
Reimagine how we shape and live in cities. This stream highlights innovations in circular construction, climate-resilient design, urban mobility, and nature-based urban adaptation—tools to build inclusive, regenerative cities for the future.
Cross-Cutting Themes
Across both streams, we’ll explore critical enablers of systemic change within a shifting geo-political landscape:
👩🏽🔬 Climate Financing 🌱 Jobs & Regenerative Economies 🌲 Biodiversity & Carbon Credits 🌍 Climate Risk & Resilience ⚡️Climate Innovators & Solutions
Let’s not just sustain the future. Let’s regenerate it.
Sessions
With over one million species at risk of extinction, biodiversity loss is a major threat to climate resilience. Carbon credits are one of our most effective tools to scale climate action, but they simply aren’t designed to deliver biodiversity outcomes. While carbon credits may not be nature’s silver bullet, they could still be part of the solution.
Explore how Ponterra plans to leverage carbon markets to jumpstart investment in biodiversity credits and drive ecological restoration at scale.
This session will explore how the Global Innovation Fund (GIF) leverages its investment approach to drive meaningful impact in climate adaptation and gender equity. Drawing on its diverse portfolio and recent blended finance vehicle, the session will highlight how GIF uses tailored capital structures—ranging from grants to risk capital—to strengthen urban and rural resilience in low- and middle-income countries.
Through concrete examples, it will showcase how to unlock innovative scalable solutions in fragile and underserved contexts.
Cities are rich with innovation—but too often, breakthroughs get stuck at the pilot stage.
This session explores how to break down the barriers to replicating and scaling urban innovations across systems and borders. We’ll dive into what’s working, what’s missing, and how to better connect innovation ecosystems across public, private, and civic sectors. From local success stories to global pathways for deployment, we’ll unpack how cities and innovators can move faster, together.

Bioregional Financing Facilities (BFFs) are a new type of financial institution designed to serve the growing bioregional movement.
By connecting integrated capital from various sources to portfolios of regenerative projects on the ground - BFFs can drive the decentralisation of financial resource governance, design of project portfolios for place-based systems change, and the transition to a regenerative economy.

Behind every urban innovation is a messy, ambitious story of collaboration between those who build and those who back. In this session, innovators and enablers come together for an honest dialogue about what it takes to pilot, deploy, and scale transformative solutions in cities.
We’ll explore what each side needs, where the frictions lie, and how we can bridge the gap between promise and widespread adoption. From early wins to global ambitions, we’ll unpack the real barriers to replication—and the strategies that help overcome them.

Discover how technology is revolutionizing nature restoration while creating sustainable business opportunities.
This session demystifies nature tech through an accessible framework: the Nature Tech Taxonomy and showcases pioneering case studies across different ecosystems and applications. Moderated by Paige, Nature Tech Collective.
