Verification of KPIs for Sustainability-Linked Loans (SLL)
We provide verification services for Sustainability-Linked Loan (SLL) KPIs.



Verification of KPIs for Sustainability-Linked Loans (SLL)
A Sustainability-Linked Loan (SLL) is a modern financing instrument where the interest margin is tied to a company's performance against sustainability targets. Since achieving or missing specific KPIs directly impacts the cost of credit, financial institutions require independent verification of these metrics.
A reliable KPI assessment confirms their authenticity, methodological accuracy, and compliance with international ESG standards. This is a key element in ensuring the credibility of data reported under an SLL agreement.
Our approach is based on recognized standards and regulations, including:
- GHG Protocol,
- ISO 14064,
- CSRD Directive and ESRS standards,
- National Assurance Standard 3002PL.
We combine expert knowledge with audit experience, allowing us to provide comprehensive KPI verification along with recommendations for ongoing monitoring and improvement. We have worked with both audit firms and industrial entities, including preparing KPI verification for PGO S.A.
