Climate change and sustainability services

Our multidisciplinary teams can help companies understand the risks and opportunities arising from climate change and sustainability issues.

In order to survive and grow in an increasingly competitive and accountable business environment, organizations are required to report not only on their financial performance, but also their nonfinancial performance.

Ignoring sustainability, environmental, health and safety (EHS) and climate change risks and stakeholder concerns around these issues is no longer an option. While CFOs may not have traditionally led the way, they are increasingly expected to play a more active role.

EY’s global Climate Change and Sustainability Services (CCaSS) teams understand the evolving pressures surrounding these challenges. As a result, they can help companies to respond by understanding and evaluating the broader value impacts and outcomes, identifying the opportunities, and supporting the reporting of nonfinancial performance risks to their stakeholders.
