Standard scientific equipment can measure the CO2 net-negativity of the products and we can determine the amount of CO2 captured and stored per tonne.
An independent third party, such as our partner DNV, a world leader in ISO certification, verifies the facility and product for carbon net-negativity at the “reasonable assurance” auditing level, higher in confidence than “limited assurance”.
All product methods are guaranteed to remove carbon from the atmosphere for at least 100 years, some for hundreds of years.
The chosen carbon removal methods can be scaled at the industrial level.
All current production that is issued CORCs is in developed countries. Besides, carbon removal methods based on biomass are required to be certified by the Forest Stewardship Council to prevent environmental, economic and social negative consequences.
The CORC issuing process is based on CO2 removal actions that have already been completed prior to issuing the CORC. This eliminates the possibility of issuing more than one CORC for the same production output and limits vintage, as CORCs that have not been retired expire at 5 years from the issuing date. Each CO2 Removal Certificate (CORC) represents a volume of 1 (one) tonne of CO2 Removal and specifies the following attributes:
CORCs can be a very cost efficient way to offset unavoidable emissions. With our methodologies we have resolved one important aspect of efficiency: CORCs are a lot lower in overhead costs per tonne removed than CDMs.
CORCs can be part of a diversified carbon removal portfolio or a unique trusted instrument, which is at the same time a tool for motivating employees and delighting customers. Companies who have purchased CORCs to neutralize emissions report that the innovation has been well received and has positioned them as climate leaders.
1. A supplier makes a claim to us on the net-negativity of their products by presenting evidence: Lifecycle Assessment (LCA) or Environmental Product Declaration (EPD) which attests that the product has absorbed more CO2 that it has emitted.
2. Based on this evidence, compliance to the Puro Standard is audited by Puro.earth’s independent assessors, such as DNV GL, who visits the production facility, validates the accuracy of data and issues an audit statement. The costs of the verification are covered by Puro.earth.
3. The verified volume of extra carbon absorbed in the products is then issued CO2 Removal Certificates (CORCs) for every metric ton of CO2 removed and stored.
4. CORCs are sold in the Puro.earth marketplace or via channel partners to companies who want to neutralize their emissions by removals and become climate positive.
