Offsetting and avoiding emissions is good, but no longer enough. We need to remove carbon dioxide from the atmosphere

Most products generate greenhouse gas emissions, but some actually remove carbon dioxide from the atmosphere. Producers of such products can receive a new certificate type; Cabron Removal Certificates. Certificates can be used by companies looking to compensate for their own or their suppliers' emissions to reach net zero. Recently leading corporations companies such as Microsoft, Stripe, Shopify, and SEB have committed to switching to carbon removals to meet their long-term sustainability targets. This is more than paying for emissions. Greenhouse gases are removed from the atmosphere in a verifiable way, and the certificate revenue is re-invested in more removals, creating a virtual circle that incentives carbon removal.

Frequently Asked Questions

What are Carbon Removal certificates?

A carbon removal certificate is an independently verified document that confirms that 1 metric ton of CO2 has been removed from the atmosphere and stored for the long term using a certified removal method. The certificate is issued to the supplier and purchased by a buyer who wants to reduce their emissions in a trusted, credible way.

What are the benefits for our company?

For suppliers of carbon-positive products such as biochar and timber building elements, carbon removal certificates offer an additional revenue stream to be invested in growth. For buyers, carbon removal certificates are a credible way to ensure that their unavoidable emissions are neutralized. Certificates can also be canceled on behalf of an end-user of a product, for example, a building owner.



What is a CO2 removal method?

It is a way to get CO2 away out of the atmosphere and stored for the long term in a stable form. The long term is defined as minimum 50 years, but some methods sequester carbon for hundreds or thousands of years.

How are carbon removal certificates different to other schemes?

Carbon removal certificates are different to both voluntary offset schemes and mandatory schemes such as the EU ETS.

Many carbon emitting sectors are included in the EU emissions trading scheme (ETS), but there are several sectors that absorb CO2 who are excluded from the ETS. Some of these sectors are eligible for carbon removal certificates. Most other offset schemes are trading emission avoidance and the absolute climate effect is difficult to measure. Carbon removal certificates have verified carbon removal from the atmosphere. 


Which carbon removal methods are available at the moment?

At the moment, there are 3 CO2 removal methods that have been verified for the issuance of carbon removal certificates:
•Biochar – a very stable and dense form of carbon that does not decompose.
•Carbonated building elements – basically concrete but without any cement. The process sequesters more CO2 than the production causes.
•Wooden building elements – wood used in building construction keeps CO2 away from circulation for a long time.

Other methods such as Direct Air Capture (DAC) and Bio-energy with Carbon Capture and Storage (BECCS) will be available in the future.

Which kind of wooden building elements qualify?

Products that fulfill the main criteria: pre-fabricated so that there is no material loss at the building site, made from timber from certified forests and well-documented product attributes, production method and data. Most mass-timber building elements such as cross laminated timber, Glulam, or wooden roofing elements can qualify.

Who buys the certificates?

Many corporates have set themselves targets for net zero carbon emissions. Whilst they are all reducing their own emissions, they usually have some emissions that are not feasibly avoided. So they choose to compensate for these emissions by buying carbon reductions. Swiss RE, TietoEvry and SEB are examples.

What is the value of the certificates?

The price of the certificates fluctuates based on supply and demand and differs based on the technology used. Prices can be found here. 1 certificate is issued for 1 metric ton of stored CO2.

How many certificates can we get?

The volume of certificates is based on the Environmental Product Declaration (EPD) or LCA for the actual product in question. As a rule of thumb about 0,6 certificates for every m3 of timber elements and 3 certificates for every 1000 Kg of biochar products.

We are planning to increase production in the future, how is this accounted for?

Certificates are issued continuously based on the output of qualified products during the previous period. When a factory is registered for the first time, the previous 18 months production can be registered, if they can be appropriately documented.

What does it cost to register and get carbon removal certificates for our products?

There is no initial cost to register a facility for certificates. Accend can assist with pre-qualification, registration, account management, auctioning and settlement. Our business model is based on a 100% transparent management fee.

Which countries can get access to certificates?

The Puro marketplace is global. Accend serves companies across the EU and EFTA region. There is a strong potential for timber product suppliers in the Nordics.

How are the certificates sold?

Certificates are sold at auction, online or via bilateral agreements.

How do I buy Carbon removal certificates for my company?

Smaller volumes can be purchased directly from alternatively get in contact to discuss a bilateral agreement.
