Mitigating Climate Change

Because we don't have time to wait

The climate is changing and so must we. Now is the time to act to stop the warming and mitigate the change.

Founded in late 2016, Climitigation is a think do tank dedicated to mitigating climate change. We are firm believers in the need for rapid and full decarbonization of the economy as soon as possible, but recognize that even if it was immediate, limiting global warming to 1.5°C (2.7°F) or less will require many hundreds of gigatonnes of carbon dioxide removal (CDR) from the atmosphere.   

Our first project, Project Vesta, has successfully started a pilot project for coastal enhanced weathering and Climitigation’s founder, Eric Matzner, has now stepped away from Project Vesta to work on developing and deploying the next permanent, gigatonne scaleable CDR technology. The next project will be focused on developing a CDR company with a business model that generates valuable and in-demand co-products, so it is self-sustaining and not reliant on voluntary carbon markets to scale up to Gt levels.

We originally set out as a “think” tank to highlight promising CDR concepts, but soon moved to directly implementing and coordinating these multidisciplinary ideas. Our research into coastal enhanced weathering (CEW) turned into Project Vesta, forming an entity that set out to deploy the world’s first pilot project for the process. Project Vesta has now started that work in the Caribbean, raised over $3m, grown to a team of 10+ members, including some of the world’s top scientists in the field, sold the world’s first CEW CDR credits to Stripe, and much more.

“Enhanced weathering holds a great promise to solve the climate change problem, and it will restore the carbonate cycle in the oceans, threatened by the lowering of the pH, which may damage ocean life, in particular the healthy growth of coral reefs.”

Project Vesta

Project Vesta is a project to sequester carbon by accelerating the weathering of a specific type of rock called olivine. When olivine interacts with water and CO2, it creates a bicarbonate and alkaline solution that eventually sequesters the carbon as rock in the sea floor and deacidifies the ocean.

While this rock is abundant and cheap, all of the unweathered sources of it are underground. The plan is to mine it, grind it, and spread it on beaches to harness the free energy of wave motion to further tumble the rocks and accelerate the weathering process. We will be creating a global network of green sand beaches to end global warming.


1 ton of olivine sequesters 1.25 tons of carbon. A volume of 7km^3 spread over the world's 2% most tidally active areas would off-set all of humanity's yearly CO2 output.


Olivine (Mg2SiO4) + 4 CO2 + 4 H2O −→ 2 Mg^2+ + 4HCO3^- + H4SiO4

CO2 is consumed, and Mg2+, Fe2+, H4SiO4 and HCO3^- are produced

The Climate Isn't Going to Change Back Without Our Help

Climitigation seeks to highlight the technologies and ideas that have the potential to radically shift the current equation on climate change back to neutral or in even in our favor. We seek to put a spotlight on those technologies and ideas that we think will be most impactful, so they can reach their full potential. If you think you can help out in your area of specialty, please reach out.
