The City of Nashville’s Livable Nashville Recommendations guides the city’s municipal sustainability actions.

Climate Mitigation Goal

The Recommendations establish a goal to reduce greenhouse gas emissions from municipal operations by 80% by 2050, with interim reduction targets of 20% by 2020 and 40% by 2030. To meet this goal, the city must reduce per capita emissions by 4.01% annually.ACEEE was unable to project if the city will achieve its near-term GHG emissions reduction goal for municipal operations because insufficient GHG emissions data were available for our analysis. 

Energy Reduction Goal

The Recommendations include a goal to reduce building resource-use by 80% by 2050, with interim reduction targets of 20% by 2020 and 40% by 2030. Additionally, the city's Department of General Services is developing a plan to achieve a 20% average reduction in energy and emissions across 9% of city buildings by square footage by 2024. The plan also calls for retrofitting 12.5% of city buildings by square footage to LEED Zero standards from 2026 to 2032.  

Renewable Energy Goal

Nashville adopted a renewable portfolio standard that has a goal to use 100% renewable energy by 2041. The Recommendations also state the intention to install 10 megawatts of renewable energy by 2020.

Efficiency Efforts in Water ServicesList All

City-wide water efficiency and goals

The Metro Water Services has not established any water efficiency programs, policies, or goals. The City of Nashville does have a water loss strategy, which involves replacing old water mains, reducing leakage rates, quickly repairing leaks, and running a MeterSense Meter Data Management System that evaluates water losses.

Water plant efficiency and self-generation

The City of Nashville has established an energy management strategy aimed at increasing energy efficiency throughout the city’s water service operation system. This strategy is focused at analyzing and optimizing energy usage in treatment plants and in watershed management operations. Metro Water Service has upcoming energy reduction projects designed and ready for construction. These projects include solar panel installation at three of the plants, switching to fine bubble aeration at the Whites Creek wastewater treatment plant, designing and pursuing LEED certification on all new buildings, and utilizing digester gas from the Dry Creek wastewater treatment plant in a CHP system.

Nashville’s wastewater treatment plant uses biogas captured from the treatment process to generate electricity onsite. Metro Water Services utilizes approximately 75% of its digester gas onsite to assist in biosolids production at the large Central Wastewater Treatment Plant. The digester gas is used to power the dryers and boilers instead of purchasing natural gas. By refining the use of the digester gas, Metro Water Services saves nearly $1,000,000 by not purchasing natural gas.
