The city’s stated goals for its local government operations are to reduce greenhouse emissions 12% under 2005 levels by 2012, 15% by 2015, and 20% by 2020.  In 2012, the City Council passed a resolution adopting the 20% by 2020 energy reduction goal.

Last updated: October 2015

Performance Management Strategies List All

Knoxville updated its greenhouse gas emissions and energy inventory in 2014 which showed the city to be on track for its goals.  The city does not have a dedicated source of funding for implementation work toward its goals; funding for projects is on a case-by-case basis through grants or departmental operating funds.

Knoxville maintains a timeline of sustainability projects, including projects for internal operations, on its sustainability website and updates it annually to include the progress of projects and milestones the city has achieved.  Knoxville publicly shares its success in increasing energy efficiency in local government operations through its sustainability blog and website.  The city allocates funds within the Office of Sustainability budget for ongoing EM&V and operations and management of ESCO project. 

Knoxville has two fulltime employees working to implement energy efficiency projects in government operations. The city's energy service performance contract includes an employee education component geared to impact employees’ energy use behavior.  We did not find other information regarding whether Knoxville offers financial or non-financial incentives for energy efficiency actions to departments or individual staff.
