GEO for Cities aims to inform, engage and support dialogue among city decision makers and other actors involved in urban issues. The GEO-6 report identified urbanization as one of five main drivers of environmental change and also looked at the impact on cities and city residents of related challenges such as climate change, biodiversity loss and pollution.

The GEO for Cities looks at these issues but also presents the types of solutions that can lead to environmentally sustainable and just cities. The GEO for Cities process is led by two co-chairs, guided by an Advisory Committee of organizations focused on urban and environment solutions (ICLEI, C40, Cities Alliance, IIED, ODI, IIHS, GCSE), has been drafted by around 20 expert authors and supported by the GEO Secretariat. The environmental and urban challenges outlined in this report require urgent and sustained attention from everyone involved in building or managing cities.

Some of the questions explored here concern the past and present. What are the urban dynamics that have resulted in environmental degradation and inequality? How can we overcome barriers to create a more sustainable future in different types of cities? How are cities affecting fresh water, land, biodiversity, the oceans and air? And how are changes in these dimensions of the environment affecting cities?

Other parts of the report address the future: What are innovative, ground-breaking visions for an environmentally sustainable and just future in cities for both people and nature? What are some of the pathways for transformative actions in cities and where can we find stories of success and hope? The report covers a wide range of environmental, social and economic issues while providing key starting points to take action and convert transformative visions into reality.
