The iiE accreditation has three levels: Bronze, Silver and Green. Typically, we suggest you start at Bronze level and work your way up as you gain knowledge of how to implement your environmental management system (EMS) effectively across your organisation.
However, if you feel your business is already doing a lot of environmental action, and you only need to pull the work together into a system, you may wish to start at either Silver or Green. To be compliant at Silver and Green level you will need at least 12 months of baseline data, and a further 12 months of data for each resource to calculate the organisations percentage improvement.
If you are already demonstrating best practice, then Investors in the Environment is a great way to gain recognition for your work and you could potentially be accredited much sooner. If you’re still unsure, our friendly team can offer suggestions.
