We can help your organisation save money and become greener with our eco accreditation scheme

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

We provide all the help, support, and networking organisations need to become greener and get recognition for 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.

What are we doing?

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.

Our vision is to create sustainable businesses and put sustainability at the heart of smart business practices. The great thing about iiE accreditation is that it is suitable for organisations of all types and sizes – from sole traders through to large multi-site employers.

IIE awards 2017 speaker


At this year’s annual iiE Awards, this region’s member businesses collectively saved:

  • Enough water to fill 12 Olympic-sized swimming pools.
  • Enough CO2 to almost fill the Houses of Parliament.
  • Enough paper to prevent 519 trees being cut down.
  • …And the amount of ‘miles not driven’ through sustainable transport choices was the equivalent of driving around the world 43 times!

“We’re thrilled to see so many businesses join in and share in celebrating one another’s accomplishments this year,” explains iiE’s April Sotomayor. “We’ve seen incredibly inspiring practice from organisations that are really pushing the outer limits of ‘green’ achievement by reducing their impacts on the environment.”

iiE remains an achievement of which we are hugely proud!

– Hunt & Coombs, iiE member

Since I have joined, our eco awareness as a business has grown and the most important thing we have learned is that if we want to make a ‘greener’ difference in the way we operate, we are the ones who have to take responsibility to follow this through. As a member, iiE has given us a structured path to follow so as to achieve our eco goals.
