Urbanization, globalization, and climate change are three mega-trends posing challenges for urban sustainability. Half the world is now urban, and cities are growing rapidly, yet urban poverty and slums are increasing. Cities generate most greenhouse gas emissions and waste. Sustainable development requires integrated rather than sectoral policies, new business models, public-private partnerships, and regional cooperation to overcome social, political, and institutional barriers to creating value locally and globally.
