Concave Summit 2026
The only Climate & Impact Investing Summit designed to reimagine & regenerate two interconnected systems: Biodiversity/Nature + Cities/Built Environment.
🌊💙🏗️
This London Climate Action Week - let's address the challenges, scale existing solutions & recreate our future.
We believe in building towards a net-positive future - with strategic matchmaking across a diverse and powerful network of innovators, funders, enablers, and ecosystem allies.
This forum is designed to power up pilots and scale breakthrough climate solutions at the intersection of nature, cities & 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 focusing on water and our oceans. Discover scalable interventions that restore ecological health, strengthen rural livelihoods, and unlock finance for the blue economy.
🔹 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 - Nature + Urban 🌱 Jobs & Regenerative Economies 🌲 Biodiversity & Carbon Credits 💚 Climate Innovators & Solutions 📈 Climate-Tech Investing
Let’s not just sustain the future. Let’s regenerate it.
