The City of Los Angeles (LA) Light Emitting Diode (LED) street lighting project is the largest LED street lighting retrofit ever undertaken globally—a collaboration between the LA Bureau of Street Lighting, the LA Mayor’s Office, the LA Department of Water & Power, and the Clinton Climate Initiative (CCI) Cities Program. Over five years (2009-2014), the project will replace 140,000 of the city’s more than 209,000 street lights with LED technology, which is expected to enhance the quality of municipal street lighting, reduce light pollution, improve street safety, and save energy and money. The US$56.9 million investment required will provide an estimated US$10 million in annual energy and maintenance cost savings (68.6 GWh/year) while avoiding at least 40,500 tons of CO2e emissions each year.
