Citizen Centric Cities: Sustainable Cities Index 2018 Summary

Core Content

The Sustainable Cities Index (SCI) 2018 evaluates the sustainability of 100 global cities based on three pillars: People (social), Planet (environmental), and Profit (economic). The report emphasizes the importance of a citizen-centric approach to sustainability, highlighting how cities must address both current and future needs of their residents. It also explores the impact of digital transformation on urban life and sustainability performance.

Main Pillars and Key Findings

1. People Pillar (Social Sustainability)

• Measures quality of life, health, education, income equality, crime, and digital services.
• Edinburgh ranks first in the People sub-index due to a highly educated and healthy workforce, low crime, and equitable income distribution.
• Top 10 cities in the People sub-index include smaller European cities, developed Asian cities, and U.S. cities like San Francisco.
• U.S. cities generally score lower in the People sub-index due to higher income inequality, crime, and limited public transport access.
• Latin American cities are clustered in the bottom quartile, with Santiago and Buenos Aires performing relatively better in health and education, but struggling in economic and environmental performance.

2. Planet Pillar (Environmental Sustainability)

• Focuses on green spaces, air pollution, water and sanitation, waste management, low-carbon infrastructure, and natural disaster preparedness.
• Stockholm leads the Planet sub-index due to low emissions, good air quality, and sustainable infrastructure.
• Northern European cities like Frankfurt and Stockholm are successful in balancing economic prosperity with environmental stewardship.
• U.S. cities generally have below-average energy use profiles, with Chicago, Houston, and Los Angeles in the bottom half of the sub-index.
• Latin American cities such as São Paulo and Salvador score well in green spaces and air quality, but waste management remains a challenge.
• Emerging cities in Asia and Africa face significant environmental challenges, including limited green space, high air pollution, and poor waste management.

3. Profit Pillar (Economic Sustainability)

• Evaluates economic performance, ease of doing business, tourism, global economic networks, transport infrastructure, and digital connectivity.
• London, Singapore, and Hong Kong top the Profit sub-index, reflecting strong economic performance and efficient business environments.
• U.S. cities such as New York and Seattle score well in Profit, with Seattle being a balanced city across all three pillars.
• Mid-ranking cities often score evenly across all pillars, indicating broad challenges in sustainability.
• Cities in the bottom quartile, particularly in Africa and Asia, struggle with output, ease of doing business, and innovation infrastructure.

Key Insights and Challenges

• Citizen Needs are Hierarchical: Basic needs like affordability, access to food and water, and shelter are critical. Failure to meet these can lead to dissatisfaction.
• Digital Transformation is a Double-Edged Sword: While digital services can enhance citizen engagement and urban management, they may also increase inequality and disproportionate influence by elites.
• Emerging Needs are Gaining Attention: Cities are increasingly addressing digital connectivity, mobility, and disaster preparedness as part of their sustainability strategies.
• Innovation and Resilience Matter: Cities with low-carbon transport, green spaces, and effective waste management are more likely to be sustainable.
• Economic Foundations are Crucial: Robust local economies, job creation, and ease of doing business are essential for long-term sustainability.

City Clusters and Trends

1. Balanced Innovators (35 cities)

• Average ranking: 21st
• Strengths: Strong in People and Profit sub-indices
• Characteristics: Embrace digital transformation, automated systems, and data-driven governance

2. Post-industrial Opportunists (33 cities)

• Average ranking: 49th
• Strengths: Focus on People and Planet
• Characteristics: Often U.S. cities undergoing post-industrial transitions, balancing immediate change with long-term sustainability

3. Evolutionary Cities (19 cities)

• Average ranking: 84th
• Weakness: Poor Profit performance
• Characteristics: Include Western cities like Athens and emerging market cities with informal economic activities

4. Fast-growing Megacities (13 cities)

• Average ranking: 85th
• Weakness: Weak Profit and Planet performance
• Characteristics: Reflect rapid urbanization and economic growth, but face environmental and social challenges

Conclusion

The report underscores that true sustainability is not just about rankings but about meeting the needs of citizens both now and in the future. Digital technologies are reshaping urban experiences, but economic and environmental foundations remain crucial. Cities must balance short-term changes with long-term planning to ensure resilience and citizen well-being. The SCI 2018 serves as a call to action for city leaders to focus on inclusive, sustainable, and forward-looking policies.
