Carbon Transformation starts here

The world’s first voluntary carbon removal marketplace for businesses.
Neutralizing your emissions with
carbon removal is possible today
Both reducing and removing carbon are key to reversing climate change. We help companies reach carbon Net-Zero by verifying CO2 removals and issuing CO2 Removal Certificates (CORCs), a new kind of carbon offset based on factual carbon removal from the atmosphere.

Each CORC represents one tonne of CO2 removed for the long term.

What goes up, must come down

At we are scaling the carbon removal industry by connecting buyers with suppliers.

Industrial carbon removal includes biochar, wooden and carbonated building elements, and other verified, science-based methods, that have a climate impact potential of up to 15 Gigatons per year by 2050.

Many companies have joined us and our suppliers are already seeing increases in volumes with the additional revenue.
How it works
Our suppliers develop carbon net-negative products. In other words, they remove carbon from the atmosphere.
Carbon removals are verified and measured by an independent third party and turned into CO2 Removal Certificates (CORCs).
Climate proactive companies buy CORCs to offset carbon emissions. This creates economic drivers to accelerate the development of CO2 removals.
After purchase, buyers can activate CORCs and use them in sustainability reporting and/or developing carbon neutral products and services. carbon removals are independently verified by

  • We are a forerunner in the circular economy and are continuously searching for ways to act more sustainably. We want to be involved in developing the Puro platform, with which it is possible to offer CO2 neutral services to our customers. It is vital for us that the CO2 removal methods are long-term and verified so that our customers can trust that compensation is done to highest standards. Puro has taken care of this especially carefully. This is very important work where we want to be involved.

  • Even radical emission reductions are not enough to halt the climate change, but we must also actively remove CO2 from the atmosphere. As Compensate grows, a marketplace where revenue goes to the most effective removal method CO2 is absolutely necessary. This is why we are exited about Puro building a marketplace for this purpose.

  • The Puro marketplace is a valuable step to enable climate entrepreneurship in agriculture. We support carbon farming to become an approved CO2 removal method in the future. These solutions can help farmers to get a new source of income and develop value added products.
