Scope 3 · Category 15

Scope 3 Category 15: Investments

Scope 3 Category 15 covers emissions associated with investments — equity, debt and project finance — proportional to your share of the investee. It is the primary Scope 3 category for financial institutions and holding companies, and usually follows PCAF or similar financed-emissions methods on top of investee inventories.

Category 15 covers emissions associated with investments — equity, debt and project finance — typically using PCAF or similar financed-emissions methods.

Financial institutions and holding companies should prioritise Category 15. Use outstanding investment amounts and investee emissions or sector intensities per your financed-emissions framework.

Non-financial SMEs often exclude Category 15 as immaterial — document that decision.

Frequently asked questions

Is Category 15 only for banks?
It is most material for financial institutions, but any organisation with material investments may need it. Many non-financial SMEs justifiably exclude it.
What method should I follow?
PCAF (Partnership for Carbon Accounting Financials) is the common reference for financed emissions. Align attribution factors with that guidance.
Do I need investee Scope 3?
Start with investee Scope 1/2 where data exists; expand to investee Scope 3 as data quality allows and your framework requires.
How is this different from Category 1 shareholdings?
Minor shareholdings held as investments follow Category 15 methods, not Category 1 purchased goods.
What if investees have no inventory?
Use sector intensity proxies and flag data quality scores — then engage for primary inventories on the largest positions.
