Is that "official" figure from Toyota, or from an independent testing group? A huge number of manufacturers have been caught or admitted to, cheating on their emissions figures - including CO2 levels. Claimed figures are basically worthless.
Why would you think that a compact hybrid would have only slightly better CO2 performance compared to a city bus per passenger? It doesn't even make sense for the vehicle as a whole. Googling around, I came up with this:
https://www.bbc.com/future/article/20200317-climate-change-cut-carbon-emissions-from-your-commute https://www.bbc.com/future/article/20200317-climate-change-c...
...shows that your figure is 90g per km for the bus as a whole, not per km/passenger.
Every chart I've seen on co2 or fuel use per mile per person, busses, bicycles, and rail are king. Ride shares are the absolute worst because of all the wasted miles....followed by private SUV and car use.
If you do a google image search for "co2 emissions per passenger mile" you can see endless charts from different studies.
- mattlondon 5y agoThe raw data is here from TfL, the people who run the buses in London: https://tfl.gov.uk/corporate/transparency/freedom-of-information/foi-request-detail?referenceId=FOI-2096-1718 https://tfl.gov.uk/corporate/transparency/freedom-of-informa... tl;dr: - single-deckers are ~900g/km, - double-deckers are ~1300g/km - hybrid are 675-780g/km So anywhere between 800% to 1500% worse than a decade-old hybrid. Of course, if the bus has 24 to 45 passengers on it, then it is better on a per-passenger basis than me in my car with my wife and kid. I couldn't find any rider-ship data from TfL, but they often appear kinda empty outside of rush hours.
