Carbon Credit Scoring Methodology



All carbon credits are equal, but some carbon credits are more equal than others. 




In theory, 1 carbon credit should equal either 1 tonne of CO2e removed or prevented from entering the atmosphere. In practice this isn’t always the case: 

  • Some carbon credit providers don’t require as stringent validation or verification requirements as others. 

  • Carbon credit providers have a financial benefit to provide as many carbon credits as possible. 

  • Carbon credits come in a range of prices, yet more expensive doesn’t necessarily equal better and cheap carbon credits incentivizes pay to pollute schemes. 

  • By scoring carbon credits and only accepting the highest quality for our portfolio, it allows our clients to fully trust that 1 carbon credit does equal 1 tonne of CO2e removed or prevented from entering the atmosphere.  

The carbon credit scoring methodology was created by MyCarbon based from The Offsetting Briefing, by the COP26 Universities Network, of which MyCarbon co-founder Toby Green was an author. The carbon credit scoring methodology has been validated by the Carbon Coalition Advisory Board. 


The Offsetting Briefing


Our scoring methodology is based on the following principals outlined by The Offsetting Briefing:

  • Permanence: If the offset involves storing carbon, is the stored carbon locked away for a very long time (ideally thousands of years) or is there a significant risk of it being re-emitted back into the atmosphere in the coming decades? Are there legal, institutional, physical, or financial protections in place to reduce the risk of reversal? 

  • Additionality: Would the emission reduction or the carbon removal have occurred in the absence of the project? 

  • Avoidance of double-counting: The reductions or removals that an offset project generates must not be claimed by more than one party (e.g. both the purchaser and the government of the project’s host country). 

  • Avoidance of “carbon leakage”: There needs to be only a very low risk that a carbon project has merely displaced the emissions to another place or time. 

  • Accurate carbon accounting: Offsets issued by a carbon project must accurately reflect the quantity of reduced or removed greenhouse gas, as well as account properly for the warming impacts of non-COclimate pollutants (e.g. short-lived climate pollutants like methane). 

  • Atmospheric outcome secured: Offsets should ideally stem from actions that are confirmed to have already taken place. For example, projects should not give full credit upfront for carbon removal that will take decades to be fully realised. If offsets are not secured, the future action that the offset pays for must be proximate (not decades away) and guaranteed. 

  • Sustainable: Offsets must not cause environmental or social harm, must protect the self-determination of local communities and Indigenous Peoples, and should ideally advance the Sustainable Development Goals (e.g. biodiversity protections, equality, etc.). 



Only carbon credit projects that pass through the scoring criteria will be placed into our carbon credit portfolio.
