Online shop closed during auctions

To join the auction, sign up here



An auction for CORCs is in progress and our online shop is closed until April 15th. 

Why is the shop closed?
Auctions are the mechanism used to determine the value-based price of CO2 Removal Certificates (CORCs), which is then used to define the online shop price. The online shop cannot be run during this time to ensure the supply of CORCs in the auction.

The shop will reopen Friday April 17th at 14.00 GMT.

Book a meeting

In the meantime, you have a chance to book a 30 min meeting with one of advisors to explore your challenges and get valuable insights on how to become carbon neutral with CORCs.

With there are three ways to buy Carbon Removal Certificates (CORCs) and become carbon neutral.



In the online shop you can easily buy up to 150 CORCS using a credit card. The price of CORCs is the Weighted Average Price in the last auction plus 20%.




Register here and you can easily place purchase bids for specific carbon removal method, quantity and price of CORCs. Buyers should bid with a price that reflects the business benefits of buying high-quality carbon offsets.




With a Pre-Purchase Agreement buyers secure availability and price by agreeing with one or more suppliers to buy a predetermined amount at a set price in the next auction. To arrange a Pre-Purchase Agreement please contact us.



Our mission is to mobilize the world’s economy to reward carbon net-negative emissions. Trading on Puro marketplace creates economic drivers to accelerate the development of carbon removal today.


How do the auctions work?

Auctions are run every two months for four days, with two auction rounds that last 48 hours. The current auction will take place from April 13th to 17th, 2020. Buyers and sellers who register here get access to the auction platform. It is very easy to place a bid and get a match in the auctions.





In the first 24-hour window, buyers enter their purchase bids by defining the removal method, how many CORCs they want to buy and at what price. In the next 24 hours, sellers, who have been issued CORCs after going through our verification, choose which bids to accept.

The matched bids are published after this first round.



Another round of bidding goes on for 48 hours. (The second round is the same as the first round, but buyers and sellers can adjust their strategies based on learnings from the first round. Please note that no bids are carried over to the second round.)

CORCs are invoiced and then transferred to the winning bidder, who can use it in sustainability reporting. For transparency, all participants can see the matched deals.

Welcome back to the online shop on April 17th or register here to participate in the auctions. In the meantime, read our blog post on How to become a carbon neutral company with carbon removal.
