Durability refers to the time the carbon is locked away and not returned to the atmosphere as CO2. CO2 Removal Certificate (CORCs) are classified into two durability categories: CORC 100+ for methods that secure CO2 for at least 100 years and CORC 1,000+ for methods that secure CO 2 for over 1,000 years.

ZeroEx stands for delivering highest quality carbon removal projects with a high aspiration for scientific integrity and supporting communities – the reason why we as a company focus exclusively on launching enhanced weathering projects set-up locally within the strictest regulatory frameworks in Germany and Central Europe. The concept of enhanced weathering accelerates the natural weathering process of silicate rocks by spreading smaller fractions of rock, derived as a by-product from quarrying operations, on agricultural land, sequestering carbon in the process and geologically storing with a permanence of over 1,000+ years. Enhanced weathering does not only help combat climate change by removing carbon from the atmosphere, but also delivers numerous co-benefits such as the natural remineralization of soils and the substitution of otherwise carbon intensive agricultural lime, deacidifying soils in the process. In consequence, farmers benefit both from resulting yield increases at no cost and financially– by spreading the rock only in direct vicinity of quarries in rural regions, ZeroEx directly supports local communities. By limiting the radius of operations to an average of 25km around the feedstock source, ZeroEx is able to work with a maximum efficiency while keeping project emissions low. ZeroEx is the first operational project developer in Germany and deployed 12,000 tons of rock powder in a first pilot phase in 2023 focused on data generation using different feedstocks in five different regions of Germany. By continuously exploring high-quality feedstock sources and setting up a network of local collaborators for e.g. logistics and laboratory capacities, ZeroEx has secured potential for significant expansion over the next years. By adapting latest protocols for MRV as well as planning research projects with proprietary MRV devices to contribute to the scientific community ZeroEx sets science first and allows for fast scaling of the method without any compromise on quality.

Operational
Aperam BioEnergia is an established Brazilian company in the forestry and renewable energy sectors. Aperam runs a ~420.000 ton/year charcoal operation with emissions control in the northeast region of Minas Gerais in Brazil derived from ~126.000 ha of FSC-certified planted and native forest. These forests have important biodiversity and economic impacts on local communities. Previously, waste from Aperam's charcoal production was destined mostly to end up in cement or energy production . Now, with Aperam's first biochar project, that same material is brought back to Aperam forests and applied to the soil, where it not only serves as a durable carbon removal from the atmosphere but also acts as an important natural component for soil reconditioning and improvement. This change is only possible due to CO2 removal certificates. Aperam BioEnergia's plan for the future includes scaling biochar operations, not only to promote carbon sequestration but also to promote forest productivity improvement by improving soil properties, production process efficiency and local social and economic development. The energy that was previously generated by burning the char material is not at risk of being substituted by fossil fuel sources because of the ample availability of inexpensive renewable energy sources in Brazil. Currently, Aperam BioEnergia has capacity to produce ~30.000 tonnes/year of carbon removal.

Understanding CORCs (CO2 Removal Certificates)

A CORC is a CO2 Removal Certificate, a first of its kind carbon credit that represent one tonne of verified and removed carbon.

  • CORCs in stock:The issued CORCs available for spot purchase. It does not include CORCs that may be reserved and available for purchase via sales channel partners.
  • Available for reservation:The number of future CORCs available for reservation with advance market commitments based on the facility’s forecasting data.

Facility types:

  • Operational:The facility is operating as a carbon removal facility. CORCs have already been issued and are available on the spot market or the facility will undergo its first audit in the upcoming months.
  • Future Facilities:The facility is in the development phase and is actively seeking commitments from potential buyers to purchase future CORCs.

Certification:

  • Certified:Facility has passed the first third-party audit to verify the net volume of removed carbon which has been issued into CORCs.

How do I buy CORCs?

Navigate the Puro.earth supplier listing using filters such as facility type, region, and durability to find the most suitable facility for your portfolio or purchasing needs.

  • Purchase via sales channel partners:Utilize the sales channel partners highlighted on the facility's listing page. These partners manage the transaction process on your behalf. Find the full list of sales channel partners here.
  • Direct Purchase:Click on the ‘request info from supplier’ button on the facility listing page to get in touch with the supplier directly.

This process involves opening a Puro Registry account, providing you with autonomy over your portfolio management, and control over contracting and timelines.

Contract types:

  • Purchase agreements:Used for spot market transactions for ex-post-issued CORCs
  • Pre-Purchase Agreements:Used for securing CORCs from certified facilities for future CORC issuances
  • Advance Market Commitments:Used for securing future CORCs from future facilities
