Cities/Metro-regions matter to efficiency objectives
•Cities are key engines of national economies. Most of the largest
OECD metro-regions have a higher GDP per capita than their national
average, a higher labour productivity level, and many of them tend
to have faster growth rates than their countries.
•Agglomeration economies. The concentration of jobs and firms can
be beneficial: pooled labour markets, backward and forward linkages
among firms, and knowledge spill-overs can lead to higher
productivity growth.

population live in distressed areas)
• Exclusion of immigrants

But, results from the CGE model: by 2030, metro-
regions will loose attractiveness if they continue to pollute
Changes in Attractiveness and Local Pollution Emissions across
Metro-regions
Urban strategy for green growth should be based on:
1.Effectiveness at curbing emissions, increase resilience to
climate change, reduce pollution and resource
Eg: Green Growth for a new generation of sustainable urban
policies
and resource
3.Fiscal sustainability
2/ Seeking complementarities
Implications for a new urban policy paradigm
•Conditions for successful compact city and densification policies
include typically mixed land uses, mass transit services and urban
amenities
3/ Capacity to act depends on governance models
•Strategic planning can ensure complementarities •Urban finance
needs to be streamlined (access to revenues, but also review of
side effects) •Vertical coordination is key (national governments
have a key role to foster inter- municipal collaboration, provide
incentives and sanctions)

Medium impact
Among Sectors….
Land-Use Zoning
e.g. in transport (In London,
congestion charge + bus services improvements)
GREENING LOCAL FINANCE
Optimising the opportunities for local finance, including
“greening” city revenue sources
National and sub-national expenditures on environmental
protection
in OECD countries (2005) Cities bear a substantial share of
expenditures related to climate change, e.g. environmental
protection
Reform of fees and charges to discourage driving
Fuel and parking taxes
Reform of property taxes and development fees to discourage
sprawl
Development fees to internalise cost of extending public
services
Taxes such as split-rate property taxes that encourage development
of urban land
Incentives and removing barriers for brownfields
redevelopment.
Revenue sources are not neutral (eg: property tax in Toronto, land
sales in Chinese cities favour sprawl)
What about non OECD Cities?

Some Policy Recommendations
Develop climate change adaptation strategies and
integrate environmental objectives in the regional
economic development strategy (Green PRD)
Provide incentives for inter-municipal coordination
at the local level (e.g. grants for inter-municipal
responses, or pre-conditions for infrastructure responses, or
pre-conditions for infrastructure
financing)
between inter-city competition and co-operation )
Deepen regional coordination in the Greater PRD
that includes Hong Kong and Macao
Fully implement evaluations of lower-level officials
based on environmental performance
with spatial development issues (e.g. urban growth
boundaries, and density targets)

Specific policies for economic development in townships
Greening public investment and purchasing – in infrastructure,
building, transport, communication networks and utilities. New
neighborhoods provide an opportunity to incorporate these
technologies early enough for them to be cost-effective, including
through public private partnership. City decision makers can also
reduce future energy consumption and reduce the potential for urban
fragmentation and social isolation by orienting new developments
and redevelopment projects around transportation hubs.
Supporting greener local industries by improving the eco-efficiency
of production, easing the way for green start-ups and training
local workers.
Applying green growth in fast-growing cities in developing
countries.
for green start-ups and training local workers. To attract
higher-value added industries, it can be cost-effective to create
incentives or impose regulations for reducing air and water
pollution from existing industries (Shenzhen and Guangzhou provided
examples of these incentive programmes (and stricter
regulations).
Raising consumer awareness through consumer education and lowering
the cost of green technology purchases. City authorities have the
ability to enable private-sector partnerships that can lower energy
costs for residents while creating jobs with energy system
companies (ESCOs)
Catalysing research and the development of the green-tech clusters
that will become the engines of cities’ green economic growth over
the long term. Research clusters need not be high-tech. By taking
advantage of nearby natural resources that can be used for
renewables (e.g. solar, wind, hydropower and biofuels, cities can
attract green technology firms with opportunities for low and
high-skilled jobs.
