Across the world cities are failing to meet the needs of their people according to the inaugural Sustainable Cities Index from consultancy firm Arcadis. The Index explores the three demands of social (People), environmental (Planet) and economic (Profit) to develop an indicative ranking of 50 of the world’s leading cities. This year’s study found that there is no single city gaining top scores on all three metrics which highlights the difficult balance between the three. The top 3 cities overall are Frankfurt followed by London and Copenhagen. European cities dominate the top 10 with North America failing to make the top 10. Toronto is the only Canadian city to feature in the top 50, ranking 12 overall, 9 for environmental sustainability and inside the top 20 for people and profit. Read the full report.
