When reporting our impact as a sustainable asset manager, we include all the impact of the projects and clients that we finance. This is called the contribution approach.
We also used the contribution approach in reporting the greenhouse gas emissions of our renewable energy portfolio up to 2017. This was previously both practical and, we believe, reasonable. Since 2018, we include the attribution approach in our carbon disclosures. The above figures are calculated based on the proportion of our finance in a project.
It’s important to note that an attribution approach leads to lower carbon emissions figures than a contribution approach. That is because a contribution approach accounts for all of the emissions from a project rather than a proportion of them. This attribution approach is a more accurate reflection of our responsibility for the greenhouse gas emissions of the projects we finance and is consistent with the PCAF methodology.
