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.

    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 your organization produces.

    At Puro we only focus on measurable carbon removal. We require removal methods that can be scientifically verified, capture and store CO2 for at least 50 years and have industrial scaling potential.
  • 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. Puro removal methods capture more CO2 than they emit in manufacturing, with the net effect of removing carbon from the atmosphere. 

    The carbon capture is measured taking into consideration cradle-to-gate emissions and only the extra carbon absorbed is turned into CORCs.

    CORCs are issued based on CO2 removal actions that have already been completed prior to issuing the CORC. It is issued by the Puro 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 two ways to buy CORCs: in the online shop, and via a Pre-Purchase Agreement.

    In the online shop you can easily buy up to 1.000 CORCs using a credit card. CORCs bought in the online shop are cancelled immediately to one beneficiary. If you need to cancel CORCs for more than one beneficiary, or would like to resell CORCs, then you must buy via Pre-Purchase Agreement.

    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. To arrange a Pre-Purchase Agreement please contact us at contact@puro.earth.

    After the payment is received the CORCs are either cancelled to a beneficiary or delivered to the buyer's registry account.
  • General
    What shall I do with the CORCs after they are on my account?
    CORCs can be utilized to neutralize carbon emissions and reported in a sustainability or annual report, or they can be resold. If you want to use them to neutralize emissions then the certificates need to be immobilized so their ownership cannot be changed anymore. In our rules, this is called “cancelling” and means the same as retiring or activating the CORC. These CORCs are no longer tradable and onward sale of the indicated certificate numbers is prohibited.

    In order to activate your CORCs you need to tell us the beneficiary of the CORCs, purpose, and the emissions period and location. You will receive an official diploma stating you have neutralized your emissions with carbon removal and the following information:
    • name of the beneficiary
    • amount of tonnes that were neutralized
    • name of the carbon removal supplier
    • carbon removal method
    • date of payment
    • tracking numbers of the CORCs
    • a public link to the registry cancellation statement

    You can use the diploma in your sustainability reporting and corporate communications. You may activate CORCs in your account for different beneficiaries.
  • Buyer
    What are the benefits of buying CORCs?
    Most importantly, companies who buy CORCs neutralize their carbon emissions with carbon removal.

    Other benefits include:
    • Being part of the solution - buyers accelerate the carbon removal economy. As volumes of carbon net-negative processes grow, more carbon is removed from the atmosphere.
    • Telling the world - communicating your climate action delights customers, inspires employees and influences peers.
    • Creating carbon neutral products or services - Once you calculate the carbon footprint of your product or service, you can bundle CORCs to each unit to make them carbon neutral.
    • Ease of reporting - As CORCs are scientifically measured they can be used to match Scope 1 (Direct), Scope 2 (Indirect) and Scope 3 (Indirect value-chain) emissions and reported in ESG, sustainability and annual reports.
    • Credibility - When creating the CORC we considered the requirements of companies who are looking to fulfill ambitious climate commitments and want to avoid reputational risks associated with low-quality carbon offsets.
  • 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 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?
    CORCs are issued based on the production output from registered supplier production facilities. A buffer is set by default at 10% for all removal methods unless otherwise specified in the relevant audits or removal method methodology. This means that for every 100 tons of CO2 Removal Output, 90 CORCs are Issued, i.e. Issuance = Output*(100%-Buffer). To determine the number of certificates for a volume of production output we require:
    • 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 questions 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 remove your unavoided emissions 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 by the supplier.
  • 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, you can choose a specific methodology and check the country of origin. 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. If you would like, you can negotiate a pre- purchase agreement for a specific supplier.
  • 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. Just contact us to arrange it.

    You can either cancel the CORCs as a beneficiary, or resell them to other beneficiaries. 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. First you need to calculate what is the carbon footprint of your product or service, then you can bundle the amount of CORCs to each unit that will make them carbon neutral.
  • Marketplace
    What is the role of Fortum in Puro?
    Fortum encourages new startups to be developed within its Innovation and Venturing incubation process. Puro is one of them and the costs of setting up the venture are covered by Fortum. This is the fastest way to move forward.
  • Buyer
    How do I become a buyer?
    You can buy CORCs online or if you want to buy larger amounts, sign the Puro.earth Marketplace Agreement.
  • Suppliers
    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.
