We Love Cities

An urbanizing planet

More than half of the world’s population lives in cities. And those numbers are growing: Urban populations are expected to double from the current 3.5 billion to 6 billion by 2050 and are already responsible for more than 70 percent of global CO2 emissions. Urban dwellers’ growing appetites for different food, goods and energy put more pressure on the world’s land, waters and climate.

The good news: Solutions exist that can meet the demand of urban lifestyles without exhausting the planet’s biological capacity. WWF is dedicated to increasing political leadership, public engagement and entrepreneurship to transform cities. We do this through four main initiatives:


We Love Cities invites people across the globe to show their support for the impressive efforts 46 impressive cities are making towards sustainability. Between April 26 - June 19, we welcome you to vote for your favorites, share what you love about them via photos and videos and to submit suggestions for how cities can become more sustainable. #WeLoveCities

WWF's Carina Bergström-Hansson claims that "the battle for a future where humans live in harmony with nature will be won or lost in cities". Here she explains why the creation of truly sustainable cities is absolutely crucial to winning this battle, and how initiatives like WWF's Earth Hour City Challenge, which focus on the transition towards a sustainable and renewable energy system is the key to success.
