Sustainability and ESG Services

Materiality is the foundation for ESG strategy, risk management, and disclosure. New developments in the materiality space are changing the way in which many companies shape their ESG strategy, creating an opportunity to effectively communicate impact areas, priorities, and how you are managing them.

Deloitte’s materiality methodology and tailored set of services leverage our deep technical knowledge of Global Reporting Initiative (GRI), International Sustainability Standards Board (ISSB), Corporate Sustainability Reporting Directive (CSRD), and EU Sustainability Reporting Standards (ESRS), coupled with our understanding of your business and industry, to provide you with advice and recommendations on your ESG issues.

Our materiality services can advise you on ways to meet the expectations of stakeholders, investors, standard-setters, and regulators:

• Impact materiality: Integrates GRI guidance to advise on the outward impacts of your business.
• Financial materiality: Integrates ISSB guidance to advise on impacts to your enterprise value.
• Double materiality: Guided by CSRD to advise on ESRS requirements for disclosure.
• Materiality refresh: Guided by GRI, ISSB, or CSRD to regularly adjust for emerging prioritized impacts.

The pace and scale of change in sustainability reporting is staggering, with a mix of voluntary and regulated reporting. Many policymakers globally have finalized or proposed regulations mandating ESG disclosures, impacting public and nonpublic companies. Companies should consider having an integrated plan to address requirements.

We advise US organizations to prepare for the increased disclosure requirements including readiness for state, federal, and global rules: CSRD, ESRS, ISSB, proposed SEC climate disclosure rules—including Taskforce on Climate-related Financial Disclosures (TCFD) and Greenhouse Gas Protocol (GHG)—Federal Supplier Rule, and California SB 253. Learn more about our insights on these evolving regulations.

Our regulatory readiness services can advise you as you assess your priorities across strategy, operations, finance, and reporting:

• Gap assessment
• Data, processes, and controls
• Disclosure advisory services
• Technology and tools
• Assurance readiness
• On-call ESG technical assistance
