Investors in the Environment (iiE) is a national environmental accreditation scheme. It is designed to help organisations save time and money, reduce their impact on the environment, and get promoted for their green credentials.

We provide all the help, support, and networking you need to make your organisation greener and ensure you get recognition for your eco initiatives. Members’ achievements are highlighted at events, and promoted through e-newsletters and as online articles and case studies.


Upon successful implementation of the iiE criteria, members are awarded with the recognised stamp of certification.

The iiE scheme is unique because organisations must achieve a minimum 2% improvement in resource efficiency over an agreed baseline figure, to secure green accreditation. Other criteria include having a recycling system in place, adopting a travel plan, calculating your organisational carbon footprint and setting targets for carbon reduction.

By ultimately putting together a credible Environmental Management System (EMS), the scheme allows organisations to:

  • Save money and increase profits
  • Raise their corporate profile
  • Increase competitiveness and market share
  • Involve staff in securing operational efficiencies
