How the platform for carbon removal credits works  

Net-negative emissions

We identify suppliers with net-negative emissions. In other words, through their products and/or processes they remove more carbon from the atmosphere than they emit.

Science-based verification

The sequestered carbon is scientifically measured and independently verified by a reputable third party. After accounting for the company's own emissions, only the net negative emissions are turned into CO2 Removal Certificates (CORCs).

Industrial scale removals

Climate-conscious companies buy the carbon removal credits from certified suppliers or a Partner to neutralize the carbon emissions they could not avoid or reduce. 

Demonstrate your climate impact

Buyers can retire the CORCs in the Puro Registry to support net zero claims in their sustainability reporting and/or to develop carbon neutral products and services.

There are many ways to secure CORCs


Even a small step can create a big impact

Moving to 100% carbon removal credits is not always feasible. However, according to the Oxford Principles for Net Zero Aligned Offsetting a credible offsetting strategy that is compatible with the Paris Agreement requires organizations: “…to gradually increase the percentage of carbon removal credits they procure with the view of exclusively sourcing carbon removals by mid-century.” 

Many of our customers start with a pilot. They choose to neutralize the emissions of a geography, an office, a conference, or the business flights in a year. Others decide to become completely net zero with carbon removal. Even if removals constitute a relatively small portion of a company’s portfolio of credits initially, it is an important signal that encourages investment in carbon removal technologies.

Imagine that! With CORCs any business can give a capital injection to remove carbon from the atmosphere.
