Colorado does not ban plastic straws statewide, but allows cities to restrict distribution and many require straws only upon customer request.
While the Plastic Pollution Reduction Act addresses bags and foam, Colorado law leaves single-use plastic straw regulation primarily to local jurisdictions. Several Colorado cities, including Boulder and Aspen, have adopted upon-request ordinances requiring food establishments to provide plastic straws only when a customer asks. These rules generally exempt straws medically required for accessibility. State law preserves local authority to set stricter single-use item rules under CRS 25-17-505. Restaurants are encouraged to provide compostable or paper alternatives.
Local fines for distributing plastic straws unsolicited typically range from $50 to $250 per violation, with progressive penalties for repeat offenses.
