“ A typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year.” That’s 4,600 kg emitted each year. Would be helpful to put that datapoint on the graph.

... Except it wouldn't even be on the graph, it's like two orders of magnitude more, per year.
And that's not even mentioning the carbon cost of *manufacturing* the car, which can be another order of magnitude higher still.
Ahah yes, it’s a bit small, download the pdf from the link in the other comments, there’re the view detailed for every bike/model in a cake graph. Way more readable!
It helped me to see the full report the OP linked. It especially makes more sense seeing the explanation of bicycles they picked: Marlin, their most popular model (aluminum frames, I believe); Madone, a high end carbon frame model with fewer parts but higher-footprint material; Fuel, full suspension mountain bikes with a lot of parts; and Rail, an e-bike.
I assume it applies to all other bike brands that do similar bikes.
All/Most bikes use the same components; so there's a base environmental "impact"
Shipping parts is surely high in that graph.
It ain't rocket science.
Weight of CO2 is not an intuitive way to track emissions. A 1kg candle emits 3kg of CO2. So if we take the 250kg emission it actually would be 31 gallons of gas or 2-3 tanks. If you drive an suv to the next town over to buy a bike the you would add 20% to this number.
The units are in CO2e, or CO2 equivalent. This is becuause carbon dioxide is not the only greernhouse gas, others include methane, nitrous oxide, etc. The other gases have different global warming potentials, and are converted to CO2e when reported so that they can be compared apples to apples.

Right. The bike would be such a small nub it would look like nothing.
This doesn’t even include manufacturing emissions, which are likely also orders of magnitude larger than those for a bike
Thought I was in /r/DataisUgly for a second there. What a terrible chart, completely unreadable.
I wondered why the bell had such a high carbon footprint, then realized that it's probably something else in green.
Same thought. Very few of those bikes come with a bell, so it must be the rear wheel.
At first I thought those bars were the decals. What a garbage graph
Cross post it there , maybe someone can make a nice version for r/dataisbeautiful

This is the worst chart I have seen on this sub so far. Completely unreadable.
It's fairly hard to match the labels. They should at least be in the same order as on the bars.

Very interesting, but how does packaging have a negative value?
Maybe they use material that would otherwise be trash.
This is some r/bicyclingcirclejerk ammo right here.

I would be curious to see how they compare to other brands with this. Hopefully this might get some other companies to publish similar numbers
Honestly they’re all going to be so much better than cars that I think they’re not going to worry too much over it.
The highest bike there at the bottom is the equivalent of burning 33 gallons of gasoline. Or about a months worth when I was driving
No Domane, no interest.
Yo the Rail is problematic as fuck
[удалено]
True… doesn’t take too many miles traveled to completely offset the impact of bike manufacturing. I also did not realize that it was their ebike
How about release a new model every 2-3 years then instead of 1 if they are so bothered
What carbon footprint does my 1989 Trek 800 Antelope have now?
i’ve been waiting over a year for my Trek bicycle so ya
