What is IIE?

We are on a mission to help organisations make a positive impact on the planet

Investors in the Environment (iiE) is a national environmental accreditation scheme designed to help organisations save time and money, reduce their impact on the environment, and get recognition for their progress. iiE is an accessible and proven route to help organisations get started on their sustainability journey and keep going.

Through iiE, you will understand your impact, take action, and demonstrate progress through an externally verified and credible scheme.

Our process gives you the tools to develop your Environmental Management System and our framework focuses on four key areas of sustainable development: Leadership & Governance, Climate Change, Nature & Natural Resources, and Pollution & Waste.

Setting the baseline by implementing processes, policies and systems to manage, monitor and improve your environmental performance.

  • Establishing environmental policy & action plans
  • Gathering baseline data
  • Improving how resources are used
  • Managing & reducing waste
  • Calculating a carbon footprint
  • Communicating progress


Begin to develop organisational change by analysing data, making measured improvements through performance tracking, and working towards wider sustainable development.

  • Setting & achieving targets to reduce resource use
