The Alexander Dennis Enviro 500 is a bus from Alexander Dennis. The register lists production years 2018 to 2026; the fuel entered is diesel. The Enviro 500 is a three-axle double-decker bus unveiled in 2002; Kowloon Motor Bus in Hong Kong took the first examples. In 2014 it was superseded by the Enviro500 MMC, and the North American variant has been built in Nappanee, Indiana, since 2014.
The vehicle is classified in the category "Transit and other bus" for transit and other buses. The matching CO2 limit is 261 g/tkm (US). This is a category ceiling per tonne-kilometre from the US rules, not a measurement on the individual vehicle; it sets how much CO2 the category may emit at most per tonne carried per kilometre and is the reference value for fleet comparisons.
