Green Purchasing & Zero Waste

Boulder County is committed to Sustainability and has created Green Purchasing and Zero Waste policies to ensure all our efforts are sustainable.

Green Purchasing & Zero Waste Subcommittee

This group consists of staff from various departments who meet on a monthly basis to recommend policies and explore opportunities to expand green purchasing and zero waste efforts.


Our green purchasing and zero waste practices ensure a sustainable future for the County organization and provide a model for the community.


  • Improve our Environmentally Preferable Purchasing (EPP) policy through education and creating additional standards and requirements.
  • Approach zero waste (or darn near) through education and enhanced reduce, reuse, recycle and composting opportunities.
  • Model, promote and facilitate environmental sustainability in the community.
  • Provide education and leadership for county employees to take personal responsibility for the environment
