Sustainability reporting and assurance services

Climate change is among some of the greatest challenges of our lifetime and businesses have a vital responsibility to reduce their impact on the planet.  EY teams can help guide your organization through the complexity of environmental, social and governance (ESG) reporting, also supporting it with limited and reasonable assurance.

What EY teams can do for you

The way your business embraces sustainability issues is integral to its resilience and creating long-term value for a diverse range of key stakeholders. How your business reacts and reports on these matters is also a crucial component for building confidence and trust in your company. Because of that, the role of assurance extends beyond meeting the growing transparency demands of regulated sustainability reporting. It also empowers companies to act and be accountable, measuring their overall value and confidence in their sustainability practices.

As more mandatory sustainability reporting directives and standards emerge, companies have less and less time to prepare for their implementation. They should act now to assess the impact of those standards on their overall strategy, as well as their impact on corporate reporting, internal controls, and other key business processes.

Reporting frameworks that can potentially impact your organization:

  • Corporate Sustainability Reporting Directive (CSRD) and European Sustainability Reporting Standards (ESRS)

    At the end of 2022, the European Parliament adopted the final CSRD text, which requires companies in the EU to publicly disclose information and data around environmental, social affairs and governance (ESG) matters based on the ESRS as the underlying reporting framework. The goal is to make such information available to encourage increased investments into green and sustainable projects.

    • The scope of the directive is extended to apply to large or listed European companies and also to non-European parent companies with subsidiaries or branches operating in the EU.
    • Starting in 2024, large listed companies will begin reporting under the CSRD in line with mandatory ESRS.
    • External assurance of this new sustainability reporting will be required with limited assurance first.
    • Reporting requirements for large unlisted and listed small- and medium-sized enterprises (SMEs) will follow in 2025 and 2026, respectively.

    The CSRD supports the European Green Deal, a set of policy measures intended to combat the climate crisis by transforming the EU into a modern, resource-efficient and competitive economy, with no net emissions of greenhouse gases (GHGs), by 2050.

  • The International Sustainability Standards Board (ISSB)

    • Established by the International Financial Reporting Standard (IFRS) Foundation, the ISSB develops standards that are expected to result in a high-quality, comprehensive global baseline of sustainability disclosures, focused on the needs of investors and the financial markets.
    • The two inaugural standards, IFRS S1 General Requirements for Disclosure of Sustainability-related Financial Information and IFRS S2 Climate-related Disclosures, were introduced in June 2023.
    • IFRS S1 covers the disclosure of information about a company’s sustainability-related risks and opportunities with core content on its governance, strategy, risk management, metrics and targets.
    • IFRS S2 requires companies to disclose information about their climate-related risks and opportunities, including physical and transition risks and their potential impact on the move toward a low-carbon economy.

Sustainability assurance services

EY teams conduct independent assurance procedures over nonfinancial and other ESG disclosures, metrics and reporting. These help you to provide transparency and accountability to your stakeholders, as well as assurance to your management and those charged with governance over the quality of the information provided. Assurance can be provided with reasonable or limited assurance in accordance with global or local standards.

ESG pre-assessments

As companies continue to work to improve their ESG-related reporting, EY teams can help you to conduct pre-assessment engagements to assess the criteria, data, process, systems, and controls used in preparing and reporting ESG disclosures.

ESG pre-assessments can take several forms, but typically focus on:

  • Disclosures, data, targets and KPIs relating to ESG and sustainability
  • Integrated reports, including ESG and economic disclosures
  • Sustainability, ESG or corporate responsibility reports
  • Adherence to principles as defined by external or internal standards, or codes of conduct
  • Communications to specific stakeholders, or the board related to nonfinancial performance (for example, ESG metrics tied to executive compensation)
  • Claims related to social and environmental outcomes of specific products or services
  • GHG emissions, including organizational or lifecycle product GHG inventories
  • Carbon credits or offset issues under voluntary and regulatory standards
  • Green or social impact bonds against agreed criteria
