Key message:
Integrated, metropolitan-wide policy approach for urban sustainability
1. Experience in OECD cities: compact city policies
2. Urban green growth in dynamic Asia
3. OECD work on metropolitan indicators

The concept of compact City
… not at a city scale (in an administrative term), but at the metropolitan scale.
… not only for small- and medium-sized cities, but it is relevant to cities of all sizes, even to mega-cities!
Dense and proximate development patterns
•Urban land is intensively utilised
•Urban agglomerations are contiguous or close together
•Distinct border between urban and rural land use
•Public spaces are secured
Urban areas linked by public transport systems
•Effective use of urban land
•Public transport systems facilitate mobility in urban areas
Accessibility to local services and jobs
•Land use is mixed
•Most residents have access to local services either on foot or using public transport

Compact city policies’ contribution to
urban sustainability
Compact city characteristics
Environmental benefits
Social benefits Economic benefits
Less automobile dependency
– Fewer CO2 emissions
– Less pollution from automobiles
– Lower transport costs
– Higher mobility for people without access to a car
– Improved human health due to more cycling and walking
– Development of green jobs/ technologies
Shorter intra-urban distances
– Fewer CO2 emissions
– Less pollution from automobiles
Higher mobility of low-income households, due to lower travel costs
Higher productivity due to shorter travel time for workers
More efficient public service delivery
- Public service level for social welfare maintained by improved efficiency
Lower infrastructure investments and cost of maintenance

Compact city policies can generate synergistic impacts:

1. Set explicit compact city goals
2. Encourage dense and contiguous development at urban fringes
3. Retrofit existing built-up areas
4. Enhance diversity and quality of life in urban centres
5. Minimise adverse negative effects

• Income growth raises demand for:
– personal living space
– personal mobility
– energy consuming appliances (air conditioning, etc.)
• How to de-couple income growth and GHG emissions?
• How to accelerate necessary actions at an earlier stage of income growth and minimize the environmental consequences?
Economic growth, consumer
behaviour and greening of cities

Accessibility to public transport
• Methodology
– Distance (5 or 10 minute walk from stations) based on road network
– Average frequency (>=5 or < 5 times per hour) is combined with distance
• Result
– 51% of city’s population are living in the area accessible by public transport (3 % of very high, 7% high,
34% medium, 6% low accessibility)
Very high
