The idea of the 15-minute city (or neighbourhood) is an important one for reducing carbon emissions, and for making livable, vibrant cities - cities where you can meet most of your daily needs within 15 minutes walk or bike ride from your house, and destinations further away are connected by quality public transport. Unfortunately, it has attracted some conspiracy theories, so the term "15 minute city" itself might be falling out of favour - but the idea is a good one.
