GHG scopes included:

Scope 1 and 2 emissions currently included but Scope 3 excluded due to limitations on data availability and lack of a commonly agreed approach to incorporation and disclosure. We will look to include Scope 3 emissions in our reporting and targets when data coverage and quality improve sufficiently.


Net Zero Investment Framework


IPCC Special Report on 1.5°C, with a focus on P1/P2/P3 pathways with limited/no overshoot and limited reliance on negative emissions technologies to derive emissions target.

Additional information

Policy on coal and other fossil fuel investments:

Yes. We have an exclusion policy in place in respect of companies that derive:
• Over 25% of their revenue from thermal coal mining or sale to third parties
• Over 50% of their revenue from coal power generation
• Over 25% of their revenue from tar sands extraction
Where we are invested via pooled / comingled funds managed by third party managers, we engage and look to influence their policies over time to at least match our position in respect of thermal coal and tar sands.
