GEO-6 for Cities is a derivative product of the Sixth Edition of Global Environment Outlook (GEO-6), the UN Environment’s flagship report, which outlines the current state of the environment, illustrates possible future environmental trends and analyses the effectiveness of policies. This report will encourage urban stakeholders to get involved in finding environmental solutions for cities including sustainable livelihoods, sustainable transport, urban biodiversity, food production, sustainable infrastructure, energy, resilience, etc. GEO-6 for Cities will complement the sixth GEO by demonstrating the interactions and feedback loops between social, economic and environmental drivers and assessing how different policy options can result in more sustainable development for pathways for cities.
