green cities in the world

Best Practices for turning your city into one that’s green is tougher that just having a decent urban plan and stricter codes. But they can start with having More Parks because 75% of the population of the world is expected to be living in urban areas by the year 2050.

So solutions for mass transit will also be needed to get people around more easily and quickly without needing their own vehicle are one of the key elements to a city going green.

And while we still have quite a long way to go when it comes to making our cities green, creating competitions and a bit of competitiveness between cities for first place can only be a good thing.


As the world becomes increasingly urbanized, building and keeping sustainable cities will be challenging. Even as urgent warnings ring globally on the climate crisis, C40 estimates that the world’s cities emit more than 70% of the world’s carbon dioxide.
