In 2008, The City started using tallow (animal waste from rendering) as its feedstock for biodiesel for 180 diesel fleet vehicles. A 20% tallow biodiesel blend is used in summer months, which reduces GHG emissions by about 18% compared to petroleum diesel. For the remainder of the year a 5% blend is used. The GHG savings presented are also captured within The City\'s overall corporate emissions inventory. Other \"Green Fleet\" initiatives include use of hybrid vehicles, an idling reduction policy, preventative maintenance and “right sizing.

In 2002, The City moved Calgary\\\'s light rail transit system to wind power. The City of Calgary ‘Ride the Wind’ program uses zero-emissions wind energy to power Calgary’s light rail transit system. The program, in partnership with ENMAX and Vision Quest Windelectric (now TransAlta Wind) is now in its eighth year, saving an estimated 46,000 tonnes CO2 in 2008, and over 220,000 tonnes since 2001. Ride the Wind was the first public light rail system in North America powered entirely by the wind. Although the CTrain itself does not produce CO2 emissions, the supply of electricity used for CTrain traction power used to originate from coal or natural gas powered facilities that do produce greenhouse gases. Using wind-generated power currently reduces CO2 and as the CTrain lines are extended, the savings in emissions will also increase.

On March 12, 2007, City Council approved The City of Calgary participating in the development of the Calgary Downtown District Energy Project. The Calgary Downtown District Energy Project involved the construction, operation and maintenance of a heating plant located in the city’s downtown core that provides space heating and domestic hot water services through an underground thermal distribution system to existing and future buildings and new developments in the downtown core. The project will result in an overall reduction of greenhouse gas emissions from the city core and improvements in local ambient air quality.

The City of Calgary partnered with ENMAX, the municipally owned power utility, in \'Greening the Grid\', an initiative that will generate enough green energy by 2012 to fulfill 100 percent of the city government\'s operational needs. It\'s a major change: in the province of Alberta, much of the electricity is produced by fossil fuels, particularly coal, and significant GHG emissions are produced in the process. To meet GHG reduction targets and move plans into action, The City of Calgary committed to a long-term 20 year supply agreement with ENMAX energy to meet its corporate electricity needs through renewable energy sources and renewable energy certificates. \'Greening the Grid\' has opened the door for more energy innovation in municipal operations and the community. The City is currently the largest user of green electricity in Canada and the number one user – by percentage – of green electricity in North America. Phase 1 Complete - 75% Green Electricity; Phase 2 In Progress - 100% Green Electricity by 2012.
