Calculating borrowers' scope 3 emissions

We are currently calculating financed emissions, and wonder if we can exclude borrowers’ scope 3 emissions when it comes to setting Temperature Rating and SDA targets.

Significant portion of our borrowers/investees consist of small and medium-sized enterprises (SMEs), and we realised the potential risk of overestimating their Scope 3 emissions if we use PCAF emission factors.

To address this concern, our current plan is to primarily focus on calculating scope 1 and 2 emissions and establishing Temperature Rating targets with scope 1 and 2 emissions of our borrowers/investees.

Would it be acceptable if we only disclose the scope 1 and 2 emissions of the investees/borrowers’ financed emissions (i.e. excluding their scope 3 emissions)?

We will greatly appreciate your guidance in confirming the submission requirements.

Section 5 of the SBTi Target Validation Protocol presents information on the applicability of available science-based target setting methods to various sectors and ongoing sector development work, which can help inform FIs’ engagement efforts with borrowers and/or investees. For example, scope 3 coverage may be required for specific sectors.

For Temperature Rating targets, FIs must set a target for its portfolio scope 1 + 2 temperature score AND a target for its portfolio scope 1 + 2 + 3 temperature score.
