The Challenge
CSRD and ESRS E1 have made financed emissions a mandatory disclosure, and PCAF the standard banks use to report them. The challenge is concentrated where a lot of your relationships sit: your SME borrowers. They lack the sustainability teams, the data, and the budget to calculate their own Scope 1, 2, and 3 — so the data simply doesn't arrive. The downstream effect is familiar to every sustainability and risk team: PCAF data quality scores of 4 and 5 across the bulk of the portfolio, auditor questions you can't fully answer, and no defensible way to price climate risk into individual loans. Manual outreach doesn't scale, and spend-based proxies are losing credibility with both regulators and auditors.
