Welcome to our June Newsletter!
Great to have you on board our mission to sequester gigatons of CO₂ with natural
rock powder! 💚🪨
InPlanet selected for game-changing fund

We are happy to share some great news, which is that Milkywire & Klarna have joined us on our journey to drive Enhanced Rock Weathering (ERW) in the tropics. We were selected to remove 750t of carbon for their Climate Transformation Fund. Together, we will be able to accelerate the development of ERW, which holds incredible potential for large-scale carbon dioxide removal and will help us to address one of the most pressing challenges of our time.
This partnership is a strong endorsement of our work, but also highlights the importance of collaboration in driving meaningful change.
We’d love to hear from you

InPlanet at events

At the beginning of May, our COO Niklas Kluger spoke at Web Summit Rio, the largest technology and innovation event in the world, or as the Atlantic describes it, “where the future goes to be born”. Watch Nik’s pitch about InPlanet’s work here. Many thanks to our investors at Trellis Road who made this possible.

In May, CEO Felix Harteneck spoke at Carbon Unbound’s inaugural event in New York, a sold-out gathering of CDR Leadership from around the world, collectively focused on strengthening relationships and deepening business insights to grow the sector globally. Felix joined a panel alongside Maurice Bryson, Tito Jankowski and Pascal Michel to discuss gigaton scale carbon removal.

On May 24th, our new Head of Carbon Matthew Clarkson presented on the topic of “Monitoring and Policy for Enhanced Rock Weathering (ERW) Trials in Tropical Brazilian Agriculture” at Climate Cleanup’s Double Nature Summit. The Summit was a 4-day participatory platform bringing together a diverse range of stakeholders, including regenerative pioneers, investors, scientists, businesses, policymakers, non-governmental organizations, indigenous people, and local communities.
