Members of Investors in the Environment (iiE), a national sustainability certification scheme for organisations, saved 5,856 tonnes the previous year, meaning there has been a 21% improvement year on year.

iiE was founded in 2010 by the Peterborough Environment City Trust, and aims to help and support organisations to reduce their environmental impacts and meet their green targets.

Each year the iiE team measures the impact its members have achieved by converting resource measurements and usage into carbon equivalents and then comparing the information against the audit from the previous year.

The resources measured include electricity, gas, alternate fuels, petrol and diesel, mileage of vehicles, total waste and paper usage.

David Knight, environmental consultant with iiE, said: "To put this into perspective, this is equivalent to powering 2,267 UK houses or taking 3,467 cars off the road for a year. This is a fantastic achievement for our members – we want to thank everyone who was involved in making these reductions. The results are really great.

"Individuals and organisations at a local and global level must become more aware of the challenges that we face collectively. We need to become smarter, more efficient and considered with the resources and materials we use. iiE is working with organisations nationally to support their efforts in making these changes and reducing their resource consumption."

To achieve the government target of net zero by 2050, the UK needs to reduce all unnecessary carbon emissions and balance the remaining emissions by investing in carbon removals that will offset the amounts.

iiE members are supported in achieving their environmental certification with the help of a one-to-one support officer and many webinars and member events. For any business looking to find out more about becoming a greener organisation, iiE accepts member sign ups here.
