2016 CDP global cities report, It takes a city: The case for collaborative climate action. 

The report draws from the CDP disclosures of 533 cities across the globe, and explores the economic opportunities to both cities and the private sector from working collaboratively on climate change.

Action by cities will be essential to achieving the ambitious goals of the Paris Agreement – and cities will need to collaborate with a wide range of stakeholders to substantially reduce greenhouse gas emissions, adapt to the effects of climate change, and benefit economically and socially from a low carbon environment.
