Final Thoughts on Green Print

Provided Regulatory Requirements for Sustainability

It Got the Ball Rolling

Should Fine Tune and Strengthen Resolution

Politicians and Public Need to Continue to Support We can help by educating and informing the public

and our officials about the benefits of sustainability and the success of the work we’ve already done.
