Manager with responsibilities

Assign responsibilities

Why should you assign someone responsible for your finance but not for your environmental initiatives? The same logic applies here, by having one or several staff members in charge, you ensure that at least one person has ownership over the actions taken.

Set realistic targets

Who likes working without goals? By setting targets to reduce your energy you can get momentum going and focus from your staff to achieve the objectives. Why not providing rewards to your staff when these targets have been achieved to motivate your employees even more?

Train water management


Taking actions won't work if you don't explain your staff why you are implemeting such initiatives and what are the tasks they need to complete. Whether you are training your staff yourself or find a third party to do it for you, don't forget this important step!

Improve continual improvement

Monitor & Improve

Monitoring will ensure that your actions are paying off and will allow you to rectify in case the amount of energy you produce does not go down. It will also help you see whether your targets have been achieved!
