ICAEW Partners With IFRS Foundation and UN SSE to Expand Sustainability Reporting Training

The Institute of Chartered Accountants in England and Wales has announced strategic partnerships with the IFRS Foundation and the United Nations Sustainable Stock Exchanges initiative to support wider adoption of sustainability reporting standards.

The collaboration aims to strengthen training for accountants, listed companies, regulators, stock exchanges, and capital market participants as ISSB-aligned disclosure requirements continue to expand across global markets.

Sustainability Reporting Moves Into Mainstream Finance

ICAEW announced the partnerships during London Climate Action Week, highlighting the growing role of the accountancy profession in implementing sustainability disclosure standards.

The development comes as companies and regulators continue to adapt to the International Sustainability Standards Board framework, particularly IFRS S1 and IFRS S2. These standards are designed to provide investors with consistent, comparable, and decision-useful information about sustainability-related risks and opportunities.

IFRS S1 sets out general requirements for sustainability-related financial disclosures, while IFRS S2 focuses specifically on climate-related disclosures. Together, they are intended to help companies explain how sustainability and climate factors affect their strategy, governance, risk management, performance, and financial prospects.

For businesses, this represents a shift away from voluntary ESG communication and towards formal reporting that is more closely connected to financial performance and investor decision-making.

ICAEW Joins IFRS Foundation Training Programme

Under the partnership with the IFRS Foundation, ICAEW will support training linked to the ISSB Standards.

The IFRS Foundation has launched an ISSB Training Partner Programme, allowing selected organizations to deliver official training on the application of IFRS Sustainability Disclosure Standards. ICAEW’s participation is significant because accountants are increasingly expected to help companies connect sustainability information with financial reporting, internal controls, assurance, risk management, and board oversight.

As sustainability disclosures become more technical and regulated, finance teams are likely to play a larger role in collecting data, assessing materiality, documenting assumptions, and ensuring consistency between sustainability reports and financial statements.

This is especially relevant for climate-related reporting, where companies may need to disclose greenhouse gas emissions, transition plans, climate risk exposure, scenario analysis, capital allocation, and the financial effects of climate-related risks and opportunities.

Partnership With UN Sustainable Stock Exchanges Initiative

ICAEW has also formed a strategic partnership with the UN Sustainable Stock Exchanges initiative.

The initial focus will be on advancing sustainability reporting through stock exchanges as capacity-building partners, with activities designed for the accountancy profession. The UN SSE works with more than 130 partner exchanges, giving the programme a route into markets where listed companies are preparing for new disclosure expectations.

Stock exchanges are increasingly important in the sustainability reporting landscape. They can support listed companies through guidance, training, market education, and disclosure expectations. By working with accountancy bodies, exchanges can help companies build the technical capability needed to produce more reliable and comparable sustainability information.

For listed companies, this could improve readiness for ISSB-aligned reporting rules and help reduce inconsistencies between jurisdictions.

Why Training Matters for Companies

The practical challenge for companies is not only understanding sustainability standards but building the internal systems needed to apply them.

Sustainability reporting often requires information from finance, operations, legal, procurement, risk, sustainability teams, and suppliers. Climate reporting can be particularly complex because it may involve emissions data, energy use, climate risk modelling, transition planning, and forward-looking assumptions.

Without proper training, companies risk producing disclosures that are incomplete, inconsistent, or difficult for investors to compare. Weak implementation can also create governance and assurance problems, particularly as regulators and audit committees place greater scrutiny on sustainability-related information.

For boards, the issue is increasingly linked to accountability. Directors need to understand whether sustainability-related risks are being identified, managed, and reflected in strategy. For finance teams, the challenge is to apply discipline around data quality, documentation, internal controls, and reporting timelines.

Growing Global Momentum Behind ISSB Standards

The partnerships reflect broader international momentum behind the ISSB Standards.

Since IFRS S1 and IFRS S2 were issued, regulators and market authorities in several jurisdictions have been assessing how to incorporate them into corporate reporting frameworks. IOSCO, the global association of securities regulators, endorsed the ISSB Standards in 2023, strengthening their relevance for capital markets.

Adoption is still developing, and requirements vary by country. Some jurisdictions have already adopted or are finalising ISSB-aligned rules, while others are considering how the standards should interact with domestic sustainability reporting requirements.

For multinational companies, this creates both opportunity and complexity. A more consistent global baseline could make sustainability information easier to compare, but companies still need to monitor local implementation timelines, reporting scope, assurance expectations, and regulatory details.

Relevance for the UK Market

The announcement is also relevant for the UK, where Sustainability Reporting Standards are expected to be closely aligned with ISSB Standards.

UK-listed companies and their advisers are watching for further regulatory clarity, including how future rules may affect listing requirements and corporate reporting obligations. If UK rules follow the ISSB framework closely, companies will need finance, sustainability, legal, and governance teams to understand the standards in detail.

This creates a near-term demand for training among accountants, auditors, preparers, board members, and professional advisers. It also reinforces the role of ICAEW and similar professional bodies in helping companies move from awareness to practical implementation.

Implications for Net-Zero and Capital Markets

For investors, stronger sustainability reporting can improve visibility into how companies are managing climate risks and transition opportunities. It can also support better assessment of net zero strategies, capital expenditure plans, supply chain exposure, and long-term resilience.

For companies, improved reporting can help demonstrate whether sustainability commitments are supported by credible plans, measurable data, and governance structures. It can also expose gaps where targets are not matched by implementation, investment, or operational change.

As sustainability disclosure becomes more standardised, companies may face greater scrutiny over the quality of their net zero plans. Investors are likely to focus not only on headline targets, but also on interim milestones, emissions performance, transition risk, and financial implications.

Capacity Building Remains a Major Challenge

While the partnerships are an important step, training alone will not solve every sustainability reporting challenge.

Many companies still face gaps in emissions data, supplier information, climate risk assessment, assurance readiness, and internal coordination. Smaller listed companies and companies in emerging markets may face additional resource constraints.

The success of the ICAEW, IFRS Foundation, and UN SSE collaboration will depend on whether training leads to stronger implementation capacity in practice. This means helping companies build systems, controls, and governance processes that can support reliable sustainability disclosures over time.

A Larger Role for Accountants in Sustainability Disclosure

The announcement signals that sustainability reporting is becoming a mainstream finance function rather than a separate ESG exercise.

As ISSB-aligned disclosure frameworks expand, accountants are likely to play a central role in connecting sustainability information with financial performance, investor communication, risk management, and corporate accountability.

For companies navigating the net-zero transition, the quality of sustainability reporting will increasingly matter. It will shape how investors assess risk, how regulators evaluate disclosure, and how stakeholders judge whether climate commitments are supported by credible action.
