The legacy program
The Environmental Leadership program (ELP) is a statewide program that has been recognizing and awarding organizations in Colorado that go beyond compliance with environmental regulations by advancing sustainability in Colorado, for the past 23 years.
The program sought to aid organizations in Colorado in increasing the efficiency and sustainability of their operation through assessing opportunities for growth, recognizing success, and providing connections to like-minded businesses throughout the State.
Commitment to community
ELP has successfully granted over 150 businesses, every year, the opportunity to be recognized for their creative and innovative sustainability initiatives. We hope pay homage to this wonderful program and look forward to advancing this work in our new program.
