Capability of removal

Climacrux’s carbon removal partners have passed a thorough and strict assessment to make sure their activities result in net negative emissions. To achieve true net negative emissions, the negative emissions produced in the process have to be larger than all the positive emissions caused. The negative emissions you can purchase on this website have all emissions produced during the process already removed and are therefore the net negative emissions.

To assess if this requirement is met, a life cycle assessment (LCA) is required. In the LCA all inputs and outputs of the whole carbon removal process are examined in detail to judge its overall impact. The life cycle of producing negative emissions depends strongly on the carbon removal method. Currently we have partners using underground bio-oil injection, forestation, kelp, olivine and direct air capture and storage (DACS).

Underground Bio-oil Injection

Bio-oil is created through fast pyrolysis and then pumped into underground rock formations.

Forestation

Planting new trees removes carbon dioxide as the trees take out and store CO₂ to grown.

Ocean based with kelp forests

Macroalgae grow fast while capturing CO₂, which will then be permanently stored at the bottom of the ocean.

Enhanced weathering with olivine

The natural process in which minerals such as olivine dissolve atmospheric CO₂ is amplified.

Direct Air Capture and Storage

Modern technology allows us to capture carbon dioxide from ambient air and permanently store it.

Proof of removal

Negative emissions are an intangible product and thus having a public ledger displaying exactly how many negative emissions were produced and sold is critical to prove the removal, allow transparent auditing and avoid double selling.
