Engagement Opportunities and Programs: 

Improve our Air! 

The Denver-Boulder metro area experiences some of the worst air quality in North America. Per EPA standards, 2019 had 265 days of unhealthy air quality and 25 ozone action days – almost an entire month – where everyone was encouraged to avoid outdoor activity! The EPA also recently downgraded the region’s air quality to “severe”! So...your little actions can add up. See below for a few actions you can take to chip in: 

  • Mow Less: Mowing your lawn less creates habitat and can increase the abundance and diversity of wildlife including bees and other pollinators. Learn more here

  • Get an electric lawn mower for cheap: Recycle your old gas-fueled lawnmower with an electric lawnmower and earn a $150 rebate! Sign up here

  • Stay Informed: Check out the City's new Air Quality webpage

The SAGE Sustainable Business Program has already benefited more than 175 Westminster businesses

Since April 2021, over 175 businesses have received some type of assistance – whether it be information sharing, education, or additional outreach services; that’s approximately 6% of Westminster’s total businesses. The City also partners with local organizations and service providers (such as Eco-Cycle, Xcel Energy, and the Colorado Green Business Network) for several initiatives, including lighting upgrades, free energy assessments, and electric vehicle education. Additionally, the program distributed $6,500 directly to businesses last year through the SAGE Accelerator Grant. This year, SAGE will expand its grant funding to $3,000 per project, and offer free energy and water saving products.
