Sustainable Finance Starts in the Treasury

For years, many in finance viewed Environmental, Social, and Governance (ESG) criteria as a matter for sustainability teams and investor relations. Treasury’s involvement often remained limited to passive reporting of basic metrics. That era is now over. With increasing regulatory mandates and investor demands for transparent, verifiable data, treasury is at the forefront of the ESG agenda. This new mandate requires the function to move beyond mere compliance, instead actively managing and leveraging ESG data to create strategic financial value.

Why ESG Data is a New Treasury Mandate

ESG is no longer just a “green” initiative. It is a critical component of risk management, funding costs, and corporate reputation—all core treasury responsibilities.

• Access to Capital: The rise of sustainable finance has linked a company’s ESG performance directly to its ability to raise capital. For example, issuing green bonds or securing sustainability-linked loans often requires treasury to provide and attest to specific ESG metrics. Consequently, failing to meet these metrics can result in higher interest rates or even limited access to funding.
• Risk Management: As we discussed in our article on “Green Swans,” climate-related risks are also financial risks. Therefore, quantifying and reporting on them requires granular data that treasury, with its oversight of financial flows, is uniquely positioned to manage.
• Reputation and Stakeholder Demands: Investors, customers, and employees increasingly scrutinize a company’s ESG performance. As the steward of the company’s financial narrative, treasury plays a key role in ensuring that ESG data is credible, consistent, and integrated into financial communications.

Treasury’s Role: From Data Silos to Strategic Insight

The journey to effective ESG data management for treasury requires bridging the gap between operational data and financial reporting.

Bridging the Data Gap: Ownership and Challenges

Treasury owns a wealth of ESG-relevant data, but this information often goes overlooked. For instance, this includes:

• Supply Chain Finance data, which contains metrics on supplier emissions, labor practices, and circular economy adoption.
• Bank relationship data, including the ESG rating of a company’s banking partners and the sustainability metrics of their own lending portfolios.
• Investment data, specifically the ESG performance of assets in a company’s short-term investment portfolio.
• Capital structure data, which houses metrics tied to green bonds and sustainability-linked loans.

First, treasury must consolidate this data and work closely with sustainability and accounting teams to ensure it is consistent and verifiable. Second, they must overcome some significant hurdles. ESG data, for one, is often scattered across different departments—from procurement and operations to human resources. Treasury, therefore, needs to serve as a central hub for collecting and normalizing this data for financial reporting. Furthermore, unlike financial reporting, ESG reporting still lacks a single, global standard. This means treasury must navigate a mix of frameworks and regulatory requirements, ensuring its data is fit for purpose across multiple audiences. Lastly, sourcing reliable, auditable, and forward-looking ESG data is challenging. Treasury should work with external partners and technology providers to ensure data integrity and quality.

Leveraging Data for Strategic Value

Effective ESG data management offers a significant opportunity for treasury to create value.

• Informing Sustainable Financing: By providing clear, verifiable ESG data, treasury can not only meet the requirements for sustainable finance but also proactively identify opportunities. This could include issuing new green bonds or securing better terms on loans. Consequently, this turns ESG from a cost of compliance into a driver of lower funding costs.
• Enhancing Risk Models: Treasury can also integrate ESG data directly into its risk management models. For example, a supplier’s poor ESG rating could be flagged as an operational or reputational risk, which might then prompt a re-evaluation of that relationship.
• Improving Investor Relations: By providing an integrated financial and ESG narrative, treasury strengthens a company’s appeal to the growing pool of ESG-focused investors. Ultimately, this can positively impact its valuation and long-term capital access.

Treasury as the ESG Data Architect

For the modern treasury professional, ESG is a new, complex, and vital area of responsibility. However, by embracing the role of the ESG data architect, treasurers can move beyond mere compliance to a strategic function that leverages data to manage risk, secure funding, and drive sustainable value.

This transition requires cross-functional collaboration, investment in data infrastructure, and a proactive mindset—a new mandate for treasurers in an era where sustainability and financial performance are inextricably linked.
