Capital cities aren't usually the first places you'd think of when it comes to green, clean, pollution-free spaces. Luckily, some cities like Oslo are making sustainability a top priority.

Oslo has pledged to become a carbon neutral city by 2030, and this film highlights how urban planners, politicians, and businesses of different kinds work hard to ensure a sustainable future for the destination and its people.
