The Alexander Dennis Enviro 500 (E500) is a bus from Alexander Dennis. The register lists production years 2016 to 2017; the fuel entered is diesel. The Enviro 500 (E500) is the designation of the three-axle Alexander Dennis double-decker in its North American form; the base Enviro500 range was unveiled in 2002, with the first vehicles going to Kowloon Motor Bus in Hong Kong.
The vehicle is classified in the US category "Class 8 vocational vehicles" (heavy vocational vehicles other than tractors). The matching CO2 limit is 224 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. A double-decker carries more passengers on two decks than a single-decker on the same road footprint.
