“Which means that Copenhagen, a city of 1.2 million people, saves $357 million a year on health costs because something like 80% of its population commutes by bike.” #CityMakingMath

The EU is one of the world’s most fossil-import-dependent economies. In 2023, imports met 58% of its energy demand -near pre-crisis levels - leaving consumers exposed to price shocks. That’s far above China (24%) & India (37%); only Japan (84%) & South Korea (80%) rely more.
