Stone Certificate

Our Stone Certificate symbolizes the steadfastness and durability of this cost-effective climate solution. By purchasing this certificate, you contribute to the capture of 1 ton of CO₂ within a period of 100 years. This reflects the robustness of rocks and their ability to resist erosion over time. With this certificate you choose the power of long-term impact. We set the limit at 100 years, but in nature CO₂ sequestration continues through this olivine-rich rock. This way you clean up more CO₂ than you pay for, at the lowest CO₂ price.

100% natural

Just like Mother Earth

Trust the timeless wisdom of Mother Earth with our Stone Certificate. With this certificate you contribute to a 100% permanent solution for the removal of CO₂. With your contribution, we will apply enough olivine-rich rock that will clear the earth within 100 years of the tons purchased by you.

Effective and sustainable

Faster than nature

Exactly the method that nature has been using for millions of years, only 10,000 times faster. Our earth can no longer keep up with our massive use. And that's why we have to give her a helping hand now. With a Stone Certificate you directly contribute to a larger surface of finely ground, olivine-rich rock (0-6mm gradation). This increased surface speeds it upenhanced weatheringprocess that captures CO₂ effectively and sustainably.

"Let the earth help us save the earth"

Every kilo of greenSand clears up 1 kilo of CO₂

The mineral Olivine weathers (rusts) with the CO₂ in the rainwater. It has been proven in the lab that 1kg of greenSand Olivine captures 1kg of CO₂. However, we are convinced that it goes even faster in real nature. By using greenSand Olivine as a replacement in as many applications as possible worldwide, we can permanently capture a large part of the CO₂ surplus in a natural way. Will you also contribute?
