The City of Louisville, led by our Sustainability Action Plan, continuously works toward a more sustainable future through programs, policy and initiatives and furthered that commitment by voting to adopt the Paris Climate Agreement on July 5, 2017. 

Climate & Energy 

Renewable EnergyThe City currently has 1,045 kilowatts of solar PV generating electricity with an additional 1,000 kilowatts scheduled to come online in the near future for a combined total of 2,045 kilowatts or 2 megawatts. Once completed the estimated annual electrical generation from solar PV will be 3.8 megawatt hours, which represents more than 50% of the annual electrical consumption for City facilities!

Energy EfficiencyWorking with Partners in Energy, Louisville’s 2017 Energy Action Plan targets a 2.5% reduction in our entire community’s energy carbon footprint in the first year. Energy efficiency upgrades in City facilities are ongoing. 700 of the 1,800 streetlights in the City have been replaced with LEDs, increasing efficiency and long-term affordability. The City is planning to convert the remaining 1,100 streetlights in 2019. 

Green Building - When constructing or renovating municipal facilities, the City considers green building components and strategies to increase efficiency and occupancy comfort. 

Greenhouse Gas (GHG) Emissions Tracking - Louisville is working with Boulder County to update its 2014 Greenhouse Gas Emissions Study for the year 2016. 


E-bikes - In 2017 the City approved the use of Class 1 and Class 2 electrical assisted bikes (e-bikes) on all streets and trails. E-bikes are a great way to get more people on bikes and to ride more often and to more distant locations. As an alternative form of transportation, the use of e-bikes helps to lower carbon emissions.

Electric VehiclesThe City has invested funding in an electric vehicle for its fleet and has provided a Level 2 dual port EVSE charging station at the Louisville Public Library. 

Walkability & BikeabilityLouisville has 32 miles of contiguous bicycle trails throughout the city. We are also very proud of our walkable downtown with a Walk Score of 82! The US 36 bikeway provides a biking alternative for commuters as well as a great recreation opportunity. 

  • “First and Final Mile” Study - The city participated in this regional study and have begun to implement recommendations of the study by installing secure bike lockers on both sides of the McCaslin BRT stop.
  • Improvement to bike lanes are made as we repave major roadways.
  • New Underpass: In addition to our existing underpasses we are completing the South Street Gateway, and are planning a new one in 2018 under highway 42 at North End. In 2019, another underpass is planned under the BNSF tracks at Steel Ranch.
  • Open Space and Park Trails allow people to get around town in a great natural setting. 

Waste Management 

Recycling & Composting - The City implemented a residential “pay-as-you-throw” priced recycling and composting program in 2009, which, along with yard waste collection, diverts ~50% of Louisville’s waste stream from the landfill.

Green Purchasing - The City is committed to purchasing green products for special events. The City currently purchases biodegradable plates, napkins, utensils, and recyclable cups. It requires vendors to do the same for certain events.


Reuse Water - Coal Creek Golf Course, the Louisville Sports Complex, Miners Field and Dutch Creek Park are all irrigated with recycled water. 

Benchmarking - Facilities water usage is being benchmarked and plumbing upgrades are in process of being implemented across municipal buildings. 

A new, more efficient Waste Water Treatment plant (supported in part by a state grant) has been completed. This allows us to meet more rigorous standards in water treatment, reducing contaminants into Coal Creek.  The new plant uses more efficient pumps and blowers as well, reducing its energy use.  


Local Food & Agriculture

Community Garden The City partnered to develop the Louisville Community Garden in 2015, which maintains 20 plots for community members. 

Backyard Chickens The City of Louisville has approved the raising of a small number of chickens in residential back yards.
