EHS Maturity Model

Changing expectations and disruptive technologies can create new environment, health and safety (EHS) challenges that should be considered. To help address these issues, the EHS Maturity Model has been developed to support organizations on their EHS journey, while also supporting in maintaining compliance and driving positive business outcomes.

What EY can do for you

Years of working with companies and EHS leaders across industries has led to the development of the EY EHS Maturity Model (EY model). Using the model, we can help to support you in:

  • Identifying EHS risks and opportunities
  • Establishing strategies to transform your EHS approach and achieve your EHS goals
  • Assessing EHS maturity and helping implement transformation activities
  • Implementing EHS enablers, including IT platforms, covering all aspects of EHS management

Regardless of your organizational challenges or your current maturity, the EY model can help to guide you on your journey to an improved EHS culture.

The EY Model supports organizations by:

1. Linking EHS to business outcomes

The EY model considers EHS as an outcome of business culture and strategy rather than as a “process.” The model challenges traditional EHS concepts in the workplace that have focused on compliance and  safety management systems.

2. Bringing people on the journey

Work performed using the EY model is collaborative and interactive in application, which means people who are involved feel their input is valued.

3. Responding to a changing working world

The EY model is innovative ­— incorporating elements in response to a changing working world. The model considers emerging trends such as digital technology and mental health, which other EHS maturity models in the marketplace may not effectively consider. 

4. Being flexible to your needs

The EY model is a framework that can be customized to suit your needs. The framework can be utilized for targeted support in a specific area, such as assessing critical risks or developing an EHS strategy. Alternatively, it can be generalized to fit within organizational priorities and budget.

Underpinned by years of working with companies and EHS leaders across all industries, the EY Climate Change and Sustainability Services (CCaSS) team has developed the EY EHS Maturity Model framework, which can help to evaluate and guide you on your EHS maturity journey.
