1 Urban Planning and Climate Change: OECD s perspective Tadashi Matsumoto, Ph. D. Coordinator, National Urban Policy, Climate Change and Green Growth Cities, Urban Policies and Sustainable Development, OECD Presentation at CITIES IN THE AGE OF CLIMATE CHANGE 28 November 2017, Vienna, Austria

2 Introducing the OECD

3 Main lines of urban work at OECD Reviews of metro-regions and national urban policy to identify opportunities to address competitiveness, sustainability and governance challenges (China and Mexico, 2015; Vietnam, 2018) Horizontal analyses targeting, for example, urban competitiveness, climate change, port cities and green growth in cities (Governing the cities, 2015; The Metropolitan Century, 2015) Policy dialogue on urban issues to facilitate knowledge exchange and best practices to inform policymakers agendas (Roundtable of Mayors and Ministers) Statistical indicators on urban and metro-regions the fundamental tools for enhancing cross-country comparison and improving policy evaluation 3

4 OECD reviews on urban issues National Urban Policy Reviews Assess the role of central government in both explicit and implicit urban policies as seen through multiple lenses, including economic, social and environmental perspectives Poland, Korea, Chile, Mexico, China, Kazakhstan Metropolitan Reviews Applied its method for territorial reviews in over 25 cities and metropolitan regions, including, Valle de México (Mexico), Rotterdam-The Hague (The Netherlands), Chicago (USA), Toronto (Canada), Venice (Italy), Gauteng (South Africa), Guangdong (China).

5 The OECD regional/metropolitan database The RDB & MDB includes statistics on: Demographic, regional accounts, labour, innovation Social and environmental indicators Well-being/Quality of life To facilitate comparability : Regions classified in 2 Territorial Levels (TLs): TL2 Territorial Level 2 (337 regions) TL3 Territorial Level 3 (1708 regions) Classified by regional type : (PU, I, PR) (PRC, PRR) Cities classified as Functional Urban Areas (FUA) Database can be directly accessed from the OECD Statistical portal: OECD MDB: How s life in your region:

11 Making Cities Work for All : Cities tend to be more unequal than countries Gini coefficient of household disposable income, 2014 Source: Boulant, J., M. Brezzi and P.

Blöchliger (2016), "Fiscal Decentralisation and Regional Disparities", OECD Economics Department Working Papers, No. 1330, GDP per capita dispersion is now greater within countries than between countries

13 POLICY RESPONSES: HOW CAN URBAN POLICIES ADDRESS CLIMATE CHANGE? 13

14 Contributing to all dimensions of urban sustainability Identifying and promoting links between economic, environmental and social goals is both possible and critical to building cities that work. Sustainable development requires a search for policy complementarities Efficiency Equity Environmental sustainability Economic policies Sustained growth Economic reforms may increase equity Green growth policies can improve sustainability Social policies Social cohesion can increase efficiency (e.g., trust, security, knowledge) Social cohesion Inequality can be reduced without environmental harm (e.g., replace fuel subsidies with transfers) Environmental policies Green growth policies can boost innovation and efficient resource use Environmental degradation tends to hit disadvantaged groups more Environmental sustainability 14

15 Urban green growth Fostering economic growth and development through urban activities that reduce negative environmental externalities and the impact on natural resources and environmental services Green : urban activities (public and private) that reduce negative environmental impact (land-use, transport, buildings, energy, waste, and water) Growth : GDP growth primarily, but also urban quality of life

16 Urban green growth studies: Key messages Key local benefits of urban green growth: Green jobs (e.g. building energy retrofits) Urban attractiveness, through investment in public transport, etc. Competitive industry specialisation Land value increase through redevelopment Generating synergies across sectors is crucial (waste-to-energy, etc.) Land use as an anchor to other sectors Aligning financial incentives with green growth priorities Underlined importance of drivers of (green) growth: human capital, innovation and urban infrastructure

17 Compact City studies: Key messages Compact cities can not only be environmentally sustainable, but also economically viable and socially equitable. Investing in housing and public transport is crucial, in order to reduce negative impacts of compact cities and ensure equitable access to housing, services and jobs. Promoting compact city policies at the metropolitan scale is crucial.

18 Compact city policies: a comparative assessment (2012) Compact city policies can generate synergistic impacts: Compact city characteristics Environmental benefits Social benefits Economic benefits Shorter intraurban distances Fewer CO2 emissions, Less pollution from automobiles Higher mobility of lowincome households, due to lower travel costs Higher productivity due to shorter travel time for workers Better access to diversity of local services and jobs More efficient public service delivery - Higher quality of life due to access to local services (shops, hospitals, etc.) - Public service level for social welfare maintained by improved efficiency Skilled labour force attracted by high quality of life Greater productivity due to more diversity, vitality, innovation and creativity Lower infrastructure investments and cost of maintenance Source: OECD (2012), Compact City Policies: A Comparative Assessment
