Sustainable Cities

WWF is working with governments, city networks and businesses to reduce the global footprint of cities and to promote attractive One Planet lifestyles.

The battle for life on Earth will be won or lost in cities.

Executive Secretary, Convention of Biological Diversity, Ahmed Djoghlaf

An urbanizing planet

Over half the world’s population now lives in cities, and the urbanization trend is expected to continue steadily until the middle of this century. Urban populations are expected to double from the current 3,5 billion to 6 billion by 2050. In other words, over the next four decades, humanity will be building as much urban infrastructure as we have built so far throughout history.

Cities have huge footprints

The global footprint of cities is quite daunting. Both directly through urban sprawl, but even more indirectly through consumption in cities. Urban dwellers’ growing appetites for various food groups, goods and energy services put increasing pressure on the world’s land, waters and climate. More than 70 per cent of all fossil fuel related CO2 emissions today are generated by residents in cities.

Attractive urban One Planet lifestyles

The good news is that solutions already exist that can provide urban dwellers with attractive lifestyles within their fair share of the planet’s biological capacity.

However increased political leadership, public engagement and entrepreneurship are all required if these solutions are to be instrumental in making such a positive transformation of cities possible. WWF’s emerging work on sustainable cities aims to inspire and support this transformation.

Finance Toolkit for Sustainable Cities

Over half the world’s population currently reside in cities, which are responsible for well over 70% of global CO2 emissions. As the trend toward urbanization continues, it is projected that hundreds of trillions of dollars will be invested in urban infrastructure and use in the coming three decades. WWF is convinced that these investments must be leveraged to ensure the creation of sustainable cities thereby reversing the trend of escalating emissions.

We Love Cities
We Love Cities invites people all over the world to show their support for the impressive efforts finalist cities of the Earth Hour City Challenge are making towards sustainability.

What WWF is doing

  • The Earth Hour City Challenge: is an initiative designed by WWF to mobilize action and support from cities in the global transition towards a 100% renewable future. It also aims to stimulate the development and dissemination of best practices for climate mitigation and adaptation.
  • Urban Solutions: a global inventory of learning cases from sustainable urban development.
  • Low Carbon Cities initiative: exploring low carbon development models in different cities in China in order to learn from and replicate successful experiences.

WWF's Carina Bergström-Hansson claims that "the battle will be lost or won in cities". Here she explains why the reinvention of sustainable cities are absolutely crucial, and how initiatives like WWF's Earth Hour has pinpointed the transition towards a sustainable and renewable energy based future.
