Carbon removal is measured in tonnes of CO2 removed from the atmosphere, or the equivalent of other greenhouse gasses being removed.
Each Carbon Removal Certificate you buy ensures that 1 tonne of CO2 will be removed from the atmosphere, using a portfolio of removal solutions.
Every purchase you make is immediately reflected on your dynamic Digital Certificate under My Account, tracking your progress in eliminating your carbon footprint.
Why Carbon Removal Certificates?
With genuine carbon removals, you can be confident the CO2 will be taken out of the atmosphere. Depending on how the carbon is removed, it may be faster or slower (immediacy) and it may be removed permanently or only for a number of decades (durability).
By using a portfolio of removal solutions in our Certificates, the immediacy and durability of the removals can be tailored. Our most immediate and durable Certificate is the Technology Pioneer, featuring the highest proportions of engineered removal technologies such as Direct Air Capture and Bio Oil Sequestration.
There is a stark difference between true carbon removals and avoidance-based offsets or carbon credits. Avoidances do not eliminate your carbon footprint and unfortunately, often do not even prevent the CO2 additions that they claim to.

The Academic Perspective
Researchers at the University of Leiden have conducted a recent comparison of the different carbon removal solutions ("Negative Emissions Technologies" in their paper) to create a "comprehensive framework, integrating NETs’ critical performance aspects of feasibility, effectiveness, and side impacts, to define the optimal technology mix". This supports our perspective on the relative impacts of different technologies and where the greatest opportunity for impact lies.

Other Greenhouse Gasses
While most of the focus today is on carbon dioxide, methane (CH4), nitrous oxide (N2O) and flurocarbons all contribute to global warming too. These gases are present in much smaller amounts in the atmosphere, but actually have a greater Global Warming Potential (GWP) per molecule than CO2.
Because of this, overall greenhouse gas removal is described in terms of CO2-equivalent or CO2e, recognizing the impact of reducing the other gases. As of today, all our removal solutions and therefore our Carbon Removal Certificates are focused on CO2 removal.
