For Banks & Arrangers

Consistent activity references across every transaction

Act IDs give structuring teams, DCM desks, and ESG teams a shared reference for financed activities — reducing bespoke mapping work, improving documentation consistency, and making it easier to compare transactions across your book.

Why banks use Act IDs

Banks working on labelled bond transactions see the same underlying activities described differently by every issuer. This creates internal mapping overhead on every deal and makes it difficult to build reliable cross-transaction comparisons or internal portfolio views.

Recommending Act IDs to issuers — or referencing them in your own internal documentation — gives your team a shared, stable reference that works across transactions, issuers, and time.

Structuring and documentation

When drafting framework documentation or advising on use-of-proceeds categories, reference Act IDs alongside the issuer's own activity descriptions. This anchors documentation to a standard that SPO providers and investors can work with directly.

Internal mapping and classification

Use Act IDs as the internal reference key for activity classification across your labelled bond portfolio. Instead of maintaining bespoke mapping tables for each issuer, your team maps each issuer's categories to Act IDs once — then reuse those mappings across transactions.

Comparability across transactions

When the same Act ID appears across multiple transactions, comparison is immediate. No need to manually interpret whether "offshore wind generation" and "offshore wind farm construction" refer to the same activity.

Investor and SPO communication

Investors and SPO providers increasingly want to reference financed activities precisely. Using Act IDs in your documentation bridges the gap between issuer descriptions and the reference frameworks used by the buy side and verification community.

Loan book, bond book, investor book — one vocabulary

When your borrowers describe their investments in ACT-Us, the sustainable-finance loan book rolls up into exactly the same vocabulary used by the labelled bonds those loans refinance. The ACT-U identifier carries unchanged from borrower project ➜ loan tagging ➜ bond framework ➜ bond investor portfolio.

That makes three things easier: (1) internal reconciliation between what the ESG team reports on the loan book and what DCM discloses in a bond framework; (2) portfolio roll-up for your own treasury and ESG reporting; (3) investor response when a bond investor asks "what is actually being financed here?" — you can answer at the use-of-proceeds level without rebuilding a mapping every time.

Before Act IDs

Transaction A: "Offshore wind energy projects"
Transaction B: "Offshore wind generation facilities"
Transaction C: "Wind energy (offshore)"
Transaction D: "Marine wind electricity generation"

Manual interpretation required for every comparison.

With Act IDs

Transaction A: Offshore wind energy projects ACT-U-W4G2UF
Transaction B: Offshore wind generation facilities ACT-U-W4G2UF
Transaction C: Wind energy (offshore) ACT-U-W4G2UF
Transaction D: Marine wind electricity generation ACT-U-W4G2UF

Immediate comparability. No interpretation needed.
