FAQ

Here are the most common questions we get about Puro. If there’s something more specific that you would like to know, please don’t hesitate to get in touch.
  • General
    What is Puro?
    Puro is the first marketplace in the world to offer verified carbon removals. It’s a pioneering initiative to make carbon removal from the atmosphere verifiable and tradable through an open, online platform.
  • General
    What does the word Puro mean?
    Puro is derived from the latin purus, meaning to cleanse or purify. It can mean free of pollutants, free of flaws or imperfections.

    In Finnish, Puro means a stream, which serves as a metaphor for the marketplace to enable new revenue streams towards carbon net-negative operations and the exchange of value between sellers and suppliers.
  • General
    How is Puro different from all the other offset schemes?
    Most other offset schemes are trading emission reductions and absolute climate effect is difficult to measure. Emission reductions are very important but after possible reductions have been done, it’s essential to remove at least the same amount of CO2 that your organization produces.

    Puro has made CO2 removal verified and comparable between different methods with CO2 Removal Certificates (CORCs) that are technology-neutral.
  • General
    What is a CO2 removal method?
    It is a way to get CO2 away from the atmosphere and stored for the long term, in a stable form.
  • General
    What is a CO2 Removal Certificate (CORC)?
    A CORC is an independently verified document that confirms that 1 metric ton of CO2 has been removed from the atmosphere by one of the removal methods certified by Puro. It is issued by the registry to the supplier, purchased by the buyer and retired once the buyer has reported its usage.
  • Buyer
    How can I buy CORCs?
    There are three ways to buy CORCs: in the online shop, in auctions and via a Pre-Purchase Agreement.

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

    In the auctions, registered buyers can place purchase bids for quantity and price of CORCs. Buyers should bid with a price that reflects the business benefits of buying high-quality carbon offsets.

    In a Pre-Purchase Agreement buyers secure availability and price by agreeing with one or more suppliers to buy a pre-determined amount at a set price in the next auction. To arrange a Pre-Purchase Agreement please contact us at contact@puro.earth
  • General
    How does my purchase incentivize the carbon net-negative economy?
    Trading on Puro marketplace creates economic drivers to accelerate the development of carbon removal today. Carbon removal suppliers receive a new revenue stream which allows them to invest in R&D, operations and sales. CORC buyers can neutralize their CO2 emissions and create carbon-neutral products and services for their customers.
  • Marketplace
    Which carbon removal methods are supported/available at the moment?
    At the moment we have three CO2removal methods:
    • Biochar – a very stable and dense form of carbon that does not decompose. Its main commercial uses are city landscaping, drainage water systems and in landfills as a filter.
    • Carbonated building elements – it’s basically concrete but without any cement. The process sequesters more CO2 than the production causes.
    • Wooden building elements – wood that is used in the construction of buildings keeps CO2 away from circulation for a long time.
  • Marketplace
    Why did you choose these three carbon removal methods?
    We used the following criteria:
    • Has to be easy to measure
    • Has to remove carbon from the atmosphere for a long time (at least 50 years)
    • Has to be mature enough for scaling (out of the laboratory and have no unsolved challenges that would prevent large scale industrial deployment)
  • Marketplace
    How is the number of issued certificates determined?
    Methodology consists basically from three elements:
    • A scientific report or a certificate that states the net emissions of the product (i.e. Lifecycle Assessment (LCA) or Environmental Product Declaration (EPD))
    • Production volume of said product
    • Usage of the product (e.g. to ensure product is not burned)
  • Seller
    Is the marketplace open for new carbon removal methods?
    Yes. If you know about a process that fulfills the criteria in the previous question and have independent evidence to back it up, please let us know. If you are a supplier you can make a claim to Puro for the amount of tons of CO2 that your production sequestered retrospectively in the last 12 months. Once we have this information then we start a verification process. If you don’t have an LCA, we can put you in contact with companies who can do it for you.
  • Buyer
    My company produces a lot of emissions. Can I keep on emitting and just compensate it all?
    The priority is obviously to minimize emissions first. For all companies there are multiple cost effective ways to reduce emissions. Once the easy ones have been done and you are facing increasing costs per reduced ton of CO2, you should consider compensating with CO2 Removal Certificates (CORCs).
  • Buyer
    How can I be sure that something actually happens?
    We have an independent third party who verifies all production claims for certificates. At the moment our partner is DNV GL, a global leader in certification.
  • Buyer
    What does it cost to neutralize 1 ton of emissions?
    The price of the CORC is determined entirely based on supply and demand. We will publish the average prices from each auction afterwards.
  • Buyer
    How to bid in the auctions?
    Buying and selling CO2 Removal Certificates (CORCs), happens in auction form so that the market efficiently finds the right price and not us. Auctions are run every two months for four days, with two auction windows, or rounds, that last 48 hours. Buyers and sellers who have registered here get access to the auction platform. It is very easy to place a bid and get a match in the auctions. The process is the following:

    In the first 24-hour window buyers enter their purchase bids by defining 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.

    The purpose of the auctions is to find a value-based price for CORCs.

    Buyers should bid with a price that reflects the business benefits of buying high-quality carbon offsets. Benefits include offsetting the emissions of the company or a specific activity, lowering financial risk, increasing goodwill, augmenting social responsibility efforts and creating carbon neutral products or services.

    Sellers should accept bids that are higher than their production and verification costs and reflect the value of the climate service they are giving. Sellers should also consider the amount, timing and certainty of revenue.
  • Buyer
    What shall I do with the CORCs after they are on my account?
    Before they can be utilized in sustainability reporting or for any other offsetting purpose, the certificates need to be immobilized so that their ownership cannot be changed anymore. Here the vocabulary is varied: Some talk about cancellation (as do our rules), some about retiring, but we prefer “Activation”. In order to activate your CORCs you need to tell us the beneficiary of the CORCs, offset purpose, and the emissions period and location. You will receive an official diploma stating you have neutralized your emissions with carbon removal. You can use it in your sustainability reporting and corporate communications. You may activate CORCs in your account for different beneficiaries.
  • Buyer
    I want to share in social media that I bought CORCs to neutralize the emissions of my company. What handles can I use?
    #Puroearth #PuroCO2removal #PuroCarbonRemoval
  • Buyer
    I do not know the amount of tons of CO2 my company emits. Can Puro help us with the calculation?
    There are many carbon footprint consultants in our ecosystem. Just drop us an email (contact@puro.earth).
  • Buyer
    Can I buy CORCs of a specific methodology or country of origin?
    Yes, but we do not encourage this. We have made a ton of CO2 be equal to a ton of CO2, no matter where it is stored. The most important thing is the climate benefit of the removal. However, if you would like to you can submit bids for specific methods and country of origin during the auction, for a higher fee.
  • Buyer
    I need a very large number of CORCs, how can I ensure availability?
    You can sign a Pre-Purchase Agreement with one or many suppliers to ensure volume availability in the next auction. Just contact us to arrange it.

    You can also buy many CORCs at one auction and not activate them until you need them. For example, CORCs may be activated prior to your annual reporting, or just in time to communicate that you have offsetted a specific event, store, flights, office branch, etc.
  • Buyer
    Can I bundle CORCs with my products and services to make them carbon-neutral?
    Yes, you can.

    How do I become a supplier in the Puro.earth Marketplace?
    Register your interest here. In order for a supplier to be issued CO2 Removal Certificates (CORCs) the product that sequesters carbon and the production facility must be verified.

    There are three steps to make a claim that your production is carbon net-negative:
    1. You must have documented evidence of the carbon footprint of your production: an Environmental Product Declaration (EPD) or a Lifecycle Assessment (LCA) for cradle-to-gate carbon footprint of your production. If you don’t have an LCA or EPD , we can put you in contact with companies who can do it for you.
    2. Please, send the EPD or LCA document to contact@puro.earth.
    3. When we have this information then we will start a verification process by contacting you within the coming days.

    If you don’t have an LCA, we can put you in contact with companies who can do it for you.
