Dutch people cycle an average of 2.6 kilometres each per day. If this pattern was replicated worldwide, the study suggests, annual global carbon emissions would drop by 686 million tonnes.
This mammoth figure exceeds the entire carbon footprint of most countries, including the UK, Canada, Saudi Arabia and Australia.
Just narrowing the space for cars and adding continuous walking paths plus protected bike lanes will get you pretty far. The goal isn’t that every single person should travel by foot or car every time, it’s to make it more common to use those travel modes in general.
And build passenger trains.
