Reducing energy use across city operations and facilities makes good economic sense for several reasons. Cities both own and occupy their buildings and will directly save money from investments made in energy efficiency. Thus, the up-front capital investment in energy efficiency will return to city budgets in the form of reduced energy spend in the future. This fact sheet provides an overview of the ways city officials can finance energy efficiency investments in municipal buildings.

This resource is part of the City Energy Project Resource Library. Launched in 2019, the library is the culmination of 6+ years of work on the ground in 20 U.S. cities to reduce energy use in large buildings. The City Energy Project is a joint project of IMT and the Natural Resources Defense Council (NRDC). For more information, visit
