Project Drawdown has characterized a set of 93 technologies and practices that together can reduce concentrations of greenhouse gases in the atmosphere. It’s a gigantic project with a lot of data and analyses.
In the linked video, the author goes through the measures to find which one is the most cost effective in terms of ratio of rCO2 reduction and economic cost
The maybe surprising result is that building bike infrastructure to shift a not even big percentage of travels from cars to bicycles or ebikes, is very cheap and has a huge effect on emissions.
The premise is that all solutions should be implemented to have a significant effect, but some are easier done than other.

@delirious_owl it’s not about how fast you can go, it’s about the average speed of people moving in a city. Cars can go over 150kph and still their average speed in cities is about 13kph, that’s why their so innefficient as an urban transport.
I don’t know where you live but in most cities I’ve been and lived in, people on bikes don’t need to go fast. They need to move their children, their groceries, go to work in their everyday clothes and not end up sweaty 🤷♂️
@queermunist
When you’re late for work, you should be able to ride on a road that’s not full of pedestrians and that has passing lanes to safely go 30 kph.
We should build infrastructure that’s safe for pedestrians, safe for leiser riders in the slow lane, and also safe for normal commuters who are just trying to get somewhere.
@delirious_owl well, even on nice, flat, straight segregated cycling line, most people don’t go 30kph. Not even 25, i can see it easily here because it’s the max speed authorized legally around and not many people pass electric bikes.
Admittedly, I’m late most of time and ride around 30kph to make up for it, but the huge majority of people? They’re like 15-20 kph max, really. And it’s more than enough to go around the city 🤷♂️
