Disclosure frameworks: from box-ticking to business value

Globally, reporting is converging around The International Sustainability Standards Board (ISSB) style, investor-focused disclosures. In the UK, the government is planning to publish UK Sustainability Reporting Standards, aligned to ISSB, for voluntary use in 2026, with the aim of these becoming mandatory for certain entities in coming years. In the EU, the Corporate Sustainability Reporting Directive (CSRD) and the European Sustainability Reporting Standards (ESRS) have set a high bar for consistency, comparability, and assurance-readiness. Even for companies that are not directly in scope of these regulations, the ripple effects are being felt through supply chains and in requests for scope 3 data.

“Sustainability is often viewed as everyone’s responsibility in theory, but no one’s obligation in practice”

With the rise of integrated reporting, companies need to shift the way they disclose sustainability data. Sustainability reports have historically been viewed mostly as a PR exercise, a way for companies to show the ‘good’ they are doing, without much thought for the decision-usefulness of the data for investors. For many companies, sustainability processes, such as climate risk assessments or sustainability strategies, have been siloed and not integrated into overall risk management and business strategy. However, for both ISSB and CSRD, this is changing. Companies will now need to think about what sustainability data matters to investors, and how to report it in a way that it can be easily understood.  

This is where voluntary disclosure frameworks can help. They serve as a useful tool because they translate complex regulatory themes into practical prompts for data. Disclosure frameworks such as the Carbon Disclosure Project (CDP) and EcoVadis provide an accessible interpretation of what ‘good’ looks like. The building blocks of these disclosures are the same: governance and accountability, strategy and targets, risk and opportunity management, and credible metrics supported by strong data processes. This structure is valuable because they translate sustainability ambition into operational prompts that provide clarity around key information that investors and stakeholders need.  

When organisations treat disclosure frameworks as a management tool, three kinds of value become apparent. Firstly, they help create internal alignment. The data required to competently report doesn’t sit purely in one team, but requires coordination from colleagues in finance, risk, operations, and procurement. This forces clarity and ownership. Sustainability is often viewed as everyone’s responsibility in theory, but no one’s obligation in practice. Secondly, frameworks strengthen the discipline of evidence, bridging the gap between a well-intentioned narrative in a sustainability report to auditable, decision-useful data. Thirdly, they help build preparedness. Organisations that are comfortable disclosing sustainability data in a structured way will be more ready and capable to disclose when regulation or stakeholder scrutiny increases. These disclosure frameworks also tend to be ahead of the curve, asking for data that is not yet solidified in regulation yet, meaning companies can get an indication of how expectations will evolve.

The organisations that get the most value from voluntary disclosure frameworks tend to approach them as a continuous improvement cycle rather than an annual exercise. In practice, that starts with translating questions into a practical internal map: who owns each topic, where the data sits, what evidence is required, and what level of control exists over that information. From there, the most helpful step is often an honest assessment of maturity and evidence quality. It is easy to say a policy exists; it is much harder, but much more valuable, to show that a policy is embedding and consistently applied, with monitoring mechanisms linked to performance management.  

The value of disclosure frameworks really came to light with two clients we worked with last year. The first client was looking to increase their CDP score. On the surface, this appeared to be a relatively easy fix: they simply needed to disclose more information. However, once we began working closely with the client to collect the required data, we discovered big inefficiencies in the company, including duplication of effort, different departments not communicating with one another effectively, and a lack of ownership for many sustainability aspects. This was particularly apparent with their processes around sustainability risks.

“Ultimately, the companies that extract the most value from disclosure are those that treat it as a lever for better management rather than a documentation exercise”

Two separate teams did different risk assessments, with different findings, and the findings weren’t fully understood, quantified, or integrated into risk management processes. The most valuable outcome was not simply a stronger external submission; it was a clear internal roadmap for improvement that reduced last-minute reporting risk, greater consistency of decision-making, and supported more confident narratives with investors, clients and other stakeholders.

The second client, who achieves high scores in CDP and considers itself quite advanced in sustainability, asked us to assist with their EcoVadis submission. Through this process, we discovered that while there was good data collection and understanding of sustainability risks, there was a real lack of policies that embed behaviour into the organisation. Essentially, the good work that had been done was down to a few key individuals, but without this becoming codified in the strategies and policies of the company, there runs a real risk that if those individuals leave the organisation, that progress could be quite easily lost.

There is a broader lesson here. Reporting requirements will continue to evolve, but companies do not need to wait for perfect regulatory certainty before building the capabilities that good reporting demands. Voluntary disclosure frameworks can function as a rehearsal space, a practical way to test governance, data, and strategy against recognisable best practice. By making gaps visible in a structured way, frameworks help teams prioritise and sequence improvements. This turns what may be viewed as an overwhelming sustainability agenda into a much more manageable programme of work.

Ultimately, the companies that extract the most value from disclosure are those that treat it as a lever for better management rather than a documentation exercise. In a world where sustainability expectations are increasing, backed by supportable evidence and increased transparency, voluntary disclosure frameworks provide a practical route to better understanding and implementing sustainable practices.
