First Commission report on real-world CO2 emissions of cars and vans using data from on-board fuel consumption monitoring devices
climate.ec.europa.eu
Today, the Commission published its first report on the real-world CO2 emissions of new passenger cars and vans. The report is based on data collected in 2021 from fuel consumption monitors installed on-board of these vehicles.

EDIT clarifications:

  • the article is from the European Commission. This thing comes from a serious study based on hard facts and data.
  • Check this comment by @wooster@startrek.website, who reported the data.
  • Note that plugin hybrids are still better than pure ice, but they were expected to be much better.

It’s not a typo: plug-in hybrids are used, in real word cases, with ICE much more than anticipated.

In the EU, fuel consumption monitoring devices are required on new cars. They studied over 10% of all cars sold in 2021 and turns out they use way more fuel, and generate way more CO2, than anybody thought.

The gap means that CO2 emissions reduction objectives from transport will be more difficult to reach.

Thruth is, we need less cars, not “better” cars.

    2-7kg personal vehicles are optimal efficiency, 20-70kg personal vehicles allow for everyone to do anything (okay some of the larger electric wheelchairs blow past 70kg pretty easily, but allow me some artistic licence).

    Even busses aren’t amazing on vehicle weight per person: 16,000kg for 50 people is 320kg per person. Good suburban trains bring that back down to 230kg per person.

    So for cars to be viable your 5 seater needs to be 1600kg max. And one needs to actually use those seats.

      Maybe, but even after that there is a human component, people make mistakes and need time to react and need traffic lights and such. That’s why buses are still more efficient, you only need 1 human driving and reacting which controls the whole bus rather than 10 (50 / 5) who all need to individually react.

        I was intending it as an indication that individual cars are hard to justify.

        Additionally cars have inefficiencies around parking (time/energy spent doing it, space required) that PT doesn’t.

        They are only a good solution when ignoring/socialising so many of the costs and prioritising things that are really not important (or from a lack of imagination of what else is possible)
