As part of its commitment to environmental sustainability and promoting green building practices in its more than 4,400 restaurants, this Earth Day, Tim Hortons is announcing a new initiative to replace all existing lighting fixtures in restaurants across Canada and the United States with energy-efficient light-emitting diode (LED) lighting from Philips. The conversion program will see 485 restaurants outfitted with LED lighting in 2014 alone, translating to an estimated 6.4 million kilowatt hours (kWh) in energy savings.
