The 2019 edition of Cities100 will provide recognition for 100 of the boldest projects from leading cities around the world working to address sustainability and build a greener future. The publication will highlight solutions that are replicable and scalable, working to lower emissions and address the issues that cities face as a result of global climate change. The final selection of 100 solutions will be announced at the C40 Mayor's Summit in Copenhagen in October 2019.

 Showing ground-breaking city solutions 

Cities100, now in its fourth year, is a publication by Nordic Sustainability and C40 Cities which seeks to identify, connect and communicate the most ground-breaking solutions to the problems of climate change that impact cities today. The final 100 city solutions will serve as a guide to creating the resilient and sustainable urban environments of the future.

Cities100 aims to:

Ensure that cities demonstrating true leadership in addressing climate change are globally recognized;

Share highly replicable ‘best practices’ across cities and draw attention to outstanding performances and integrated solutions that have achieved a high level of success.

The Cities100 will give cities:

Prestigious recognition on a global scale with the 100 selected projects announced during the C40 Mayors Summit 2019 in Copenhagen;

Extensive global media coverage for the cities and their projects;

Recognition via the Cities100 publication by C40 and Nordic Sustainability.
