Biggest change you can do is bike to all your workouts. I see so many people drive 4 miles for a bike workout. Wtf. Also to make life easier and less wasteful I use Tannus solid tires on my training bikes
BINGO. That and how about just racing locally? I saw a study that shows flying is significantly more problematic for the climate that driving (obviously it depends on how much you're driving)
But I also agree that changing your diet to plant-based is huge as well because that's three times a day (or more if you're a triathlete) you can decide not add as much to the climate problem
Hmm, let's do some back-of-the envelope estimates here:
Replace 4 miles driving with cycling, say 4x/week and both ways. That's 1600 miles/year less driving, say 50 gallons less gasoline burned and thus ~500 kg CO2 less emitted.
Change diet from "average" to "no beef" cuts from 2500 to 1900 kg CO2e/year, so ~600 kg CO2e less emitted -- for a diet at 2600 kcal/day (
http://shrinkthatfootprint.com/...arbon-footprint-diet). Scale this up by 50% for a triathlete and you get ~900 kg CO2e less emitted.
Replace 2 triathlons with flights with local races you drive to. Say that's 1000 miles flying each way, so 4000 miles total. Let's use 0.2 kg CO2e/passenger mile (
https://carbonfund.org/calculation-methods/) to get ~800 kg CO2 less emitted from cutting those flights (less however much more you emit by driving).
Interestingly, they're all of similar impact, from an order-of-magnitude perspective. Diet changes might have a bit more leverage because you can be more extreme in moving to low-carbon foods, and once you cut out extraneous driving for training and flying to races it's clearly of top importance.
