Reporting on your sustainability management and performance

Decreasing resource availability along with increasing marketplace and regulatory demands and investor attention around how companies are managing their long-term sustainability risks represent a few of the trends demanding companies to increase the disclosure of non-financial information.

Data capture, measuring and reporting process

Having robust reporting processes is the first step to producing reliable and accurate information to be disclosed externally.  We offer a wide range of services around reporting including:

  • Analyse current data collection and aggregation processes and help develop new or improved data reporting methodologies
  • Develop and prioritise internal and external Key Performance Indicators (KPIs) to measure performance of sustainability programmes
  • Review internal processes and infrastructure required to gather performance data (see ‘Data Systems Advisory’ section)
  • Implement methodologies and controls for improved data collection

Sustainability disclosure

  • Benchmark your report/disclosures against leading practice
  • Map areas for improvement based on materiality analysis and stakeholder engagement (visit our 'Prioritising your sustainability risks and opportunities' page for more information)
  • Identify scope, boundary, focus and potential topics of report
  • Develop content of both online and hard copy reports
  • Help you prioritise and respond to external surveys in a uniform manner (e.g., CDP, Dow Jones Sustainability Index).

Integrated reporting

An integrated report communicates the factors most important for an organisation to create value over time. Even if the primary focus of these reports is on providers of financial capital, an integrated report benefits all stakeholders interested in an organisation’s ability to create value over time, including employees, customers, suppliers, business partners, local communities, legislators, regulators, and policy-makers. This is because how the organisation interacts with the external environment and the capitals (financial, manufactured, intellectual, human, social and natural) affects its ability to create value over the short, medium and long-term.

Deloitte LLP is part of the International Integrated Reporting Council's (IIRC) Pilot Programme Business Network and our experts can assist you in the journey towards Integrated Reporting. 


Independent assurance provides a credible way for organisations to publicly disclose their corporate responsibility and sustainability activities, along with their progress toward goals.

Stakeholders such as regulators, investors, and market analysts, among others are increasingly relying on third-party assurance to assess the quality and reliability of a company’s sustainability reporting. The risk of disclosing inaccurate or inconsistent sustainability information can lead to damaged corporate brand and loss of stakeholder trust.

Our team has extensive experience in providing independent assurance in compliance with diverse sustainability standards such as the ISAE 3000, AA1000, OHSAS 18001, GRI, International and UK Integrated Reporting Discussion papers, UN Global Compact and ISO 14001, as well as other sector-specific standards. Our sustainability experts provide assurance services to global clients in a wide range of sectors and covering environmental, health & safety, social, and economic information.

In addition, Deloitte Sustainability  has been involved in the development and revision of several sustainability reporting frameworks and standards by various organizations, including GRI G4, Sustainability Accounting Standards Board (SASB), and the Global Initiative for Sustainability Ratings (GISR). The firm is currently involved in the development of the IIRC Integrated Reporting Framework to advance disclosure focusing on the interrelationships of financial and non-financial information, and in ongoing IAASB activities to develop methodology for assurance applicable to sustainability reporting.

We can work with you to help you identify what level of assurance fits your needs, the expectations of your stakeholders, and the requirements of relevant reporting frameworks.
