Congratulations, you are invited.

So what are you actually invited to?

Climate Cleanup

We love CO2. Not as waste but as a resource. We solve climate change by removing CO2 from the atmosphere using natural solutions.

Fact: Natural climate solutions can provide over 30% of the solution to climate change but receive just 3% of the funding. To bridge this gap, Climate Cleanup works on open carbon accounting and boosts initiatives like seaweed-farms, olivine-beaches and (agro)forestry-projects.

The 1500 Club

So why the 1500 Club? With 1500 people we aim to remove the 1500 gigatons of excess CO2 in our atmosphere, using nature based solutions. This 1500 Club is by and for parents, entrepreneurs, investors, children, decision makers and anyone who wants to suck CO2 with us.

Join the club!
