What did the client need?

The business already held SBTi-validated targets and had made material progress; a 63% reduction in Scope 1 and 2 emissions and a 38% reduction in Scope 3 by 2035 against a 2023 baseline. However, as is often the case for modern service businesses, most emissions came from indirect sources, with Scope 3 accounting for an estimated 99% of total emissions. This was dominated by Purchased Goods & Services.

The portfolio company and its sponsor wanted to turn genuine decarbonisation into a financial return. The best approach to achieve this was an ESG Margin Ratchet, which BIP.Verco supported them with. This is a mechanism inside a Sustainability-Linked Loan (SLL) that lowers, or raises, the interest margin according to sustainability performance. It translates verified climate progress into a lower cost of borrowing.

The complexities sat within the design. With Scope 3 dominating the footprint, and being calculated using spend-based emission factors, the absolute Scope 3 reduction target would punish the company for growing. As revenue rises, calculated emissions rise with it (even if suppliers are decarbonising). Therefore, the firm needed KPIs that were:

• credible enough to satisfy a lender;
• material enough to matter; and
• structured so that success in the business did not become failure against the loan.

How did BIP.Verco support the client?

BIP.Verco designed a two-KPI ESG Margin Ratchet. The team also provided costed decarbonisation on areas that would improve the company’s annual operating expenditure from a proprietary list of lived experience decarbonisation ROI projects.

It is calibrated to deliver a total margin adjustment of 10 basis points (bps). It also aligns with the LMA's Sustainability-Linked Loan Principles (March 2025) and ICMA guidance.

The structure deliberately pairs a highly controllable anchor with a forward-looking, growth-safe measure of Scope 3 progress.

The strength of the design lies within the pairing, with KPI 1 securing the ratchet in the most controllable, verifiable part of the footprint. Scope 1 and 2 sit on existing compliance infrastructure and an already-validated SBTi trajectory, giving the lender absolute-emissions certainty.

KPI 2 measures influence and data maturity, not absolute supplier reductions. This means the metric improves as the company engages its supply chain and upgrades its data, regardless of how fast the business grows.

What was the result?

• £207,500 in annual OpEx savings from the Business Travel and Real Estate levers, against roughly £104,500 of CapEx — a two-year average payback that flows straight to EBITDA.
• A 10 bps reduction in the cost of debt on the senior facility, converting decarbonisation progress into a recurring saving that compounds over the hold period.
• A developed climate strategy for the portfolio company, and measurable progress against the sponsor's own private equity Science-Based Target.
• A reproducible template. A hybrid ratchet plus costed levers that can be rolled out across other portfolio companies with leased offices, business travel and a service-heavy supply chain.
