My understanding is that motorcycles (especially modern motorcycles) produce significantly less CO2 equiv than modern cars - in no small part due to their ability to not get caught in traffic.
Most commuters are 1 person per vehicle.
CO2 is only a small part of the story
the motorcycle used 28% less fuel than the comparable decade car and emitted 30% fewer carbon dioxide emissions, but it emitted 416% more hydrocarbons, 3,220% more oxides of nitrogen and 8,065% more carbon monoxide.
So yeah. Not exactly great. And btw our option on those hydrocarbons have changed a LOT in the last 13 years when this was published. See the decline of diesels post dieselgate.
That story is over a decade old and looks at motorcycles that aren’t anything close to modern standards.
Modern 4 stroke motorcycles are more fuel efficient and all around less polluting than cars.
None of this really matters as the best form of transportation is obviously mass transit, walking or bicycle but it does make sense to split out motorcycle.
That’s just not true though.
Motorcycles do not have to meet the same stringent requirements as cars because they aren’t classified as cars.
This holds true in most “western” nations.
They’re allowed higher emissions and put out more emissions per person than cars do.
You guys can downvote me all you want but 1 person in 1 car emits less emissions than 1 person on 1 motorcycle.
This is NOT an argument for cars but an argument AGAINST a single user motorized transport.
This doesn’t negate the argument against cars but it’s strange to see people arguing FOR another form of motorized transport rather than walkable cities OR mass public transportation.
You do know that almost all modern on-road motorcycles are CARB-compliant, right? Oh, but what about those small motorcycles? https://www.transportpolicy.net/standard/us-motorcycles-emissions/ As of 2006, all Class I and II motorcycles must be compliant with few exceptions.
I don’t know where you are getting your numbers for your claims. These are some significant assertions that, even prima facie, don’t make sense.
1 person in 1 car emits less emissions than 1 person on 1 motorcycle
Even from just a thermodynamics standpoint, this assertion not only feels wrong, but is wrong. Maybe a two-stroke motorcycle could out-emit a modern SOV.
Can you link those findings? I find this hard to believe since cars are so much heavier than motorcycles. Maybe a full van, is better emissions per capita? But with a single user for a car I am skeptical but open to being shown to be wrong
2022 numbers show motorcycles at 2/3rds the GHG emissions as cars.
So 2 people in 1 car is better than 2 motorbikes but 1 motorbike is easily better than 1 car.
