This UN Environment flagship publication provides best practice guidance for cities and national governments to implement sustainable heating and cooling through four chapters on technology, local policy, business models and national policies and regulations, and a fifth chapter describing a methodology for cities to develop modern district energy. The publication is based on interviews, surveys and consultations with nearly 150 respondents from 65 cities around the world in order to gather expert and local stakeholder perspectives.

The toolkit supports the development of a long-term vision for sustainable urban transport that integrates transport planning with safety, social inclusivity, reduced air pollution, and carbon dioxide emissions. It provides a step-by-step approach on how to integrate mobility planning with urban planning, prioritize accessibility for all socio economic groups, prioritize shifts to sustainable transport modes and reduce environmental impacts.

How we choose to live as a society and as individuals – what houses and build, what food we eat and grow, how we spend our spare time, and what type of transport we use – will have an enormous impact on the trajectory of human history. This publication will help policymakers, individuals and other stakeholders understand what a holistic approach to lifestyle means and how different contexts require different lifestyle solutions.


Building upon previous work of the International Resource Panel on Decoupling Natural Resource Use and Environmental Impacts from Economic Growth, this report examines the potential for decoupling at the city level. While the majority of the world’s population now live in cities and cities are where most resource consumption takes place, both the pressures and potentials to find ways to reconcile economic growth, wellbeing and the sustainable use of natural resources will therefore be greatest in cities.
