I don’t get it where is the emission coming from bicycle trips?
- s0rce 6y agoI guess you have to eat a bit more if you ride more, I certainly notice when I bike to work (5mi each way, 300ft climb) that I need to eat a bit more food. Certainly no where near the energy of a car though but its not zero. Assuming you want to maintain your weight.
- vinni2 6y agoThat’s a strong assumption. I for one wouldn’t eat less if I stopped biking. I commute to work, do shopping and go everywhere by bike throughout the year. I don’t own a car.
- s0rce 6y agoJust my experience. I stopped biking to work due to COVID and I eat less than before. I tried to just go for a 5mi ride in the morning but I'm not motivated w/o the commute and just take the dog for a walk instead.
- bradlys 6y agoAre you saying you have a mythical body that burns no calories when biking? Or are you saying you'd be willing to gain more weight because you'll never change your diet?
- Robotbeat 6y agoIt's interesting because the food you eat makes a big difference then on your commute. A diet high in beef or fresh fruit could actually make your commute WORSE than an electric car. Biomass is not a particularly low emissions energy source.
- pessimizer 6y agoI would assume from the manufacture of the bicycle.
- vinni2 6y agoReally? Manufacturing a bicycle has only 10x lower carbon footprint than manufacturing an electric car? Doesn’t sound logical to me.
- kgwgk 6y agoThe bike does need energy to move.
- dfgdghdf 6y agoTrue, but adults need around 30 mins exercise per day anyway so we can take the carbon budget from that.
- amarshall 6y ago> vehicle life cycle emissions considered emissions from the manufacture of vehicles, with aggregate carbon values per vehicle type (cars, motorcycles, bikes and public transport vehicles) derived assuming typical lifetime mileages, mass body weights, material composition and material-specific emissions and energy use factors. and > The observed e-bike share was 4.5%; therefore, average emissions include 4.5% e-bike, 95.5% normal bike. It’s not totally clear to me if the emissions required to produce the energy the human burned to power the bicycle are included—it would certainly vary quite a bit based on the food.
