10 Cities and Energy Sustainability OECD Green Growth Studies Compact City Policies Propose compact city strategies and ideas for achieving better outcomes and highlights governance challenges for implementing practical strategies. The contribution of the compact city to urban sustainability 3. More district-wide energy utilisation and local energy generation Less energy consumption per capita, fewer CO2 emissions Development of green jobs/technologies More energy independence Indicators related to compactness Indicators related to the impact of compact city policies Dense and proximate development patterns Urban areas linked by public transport systems Accessibility to local services and jobs Environmental Social Economic 1. Population and urban land growth 2. Population density on urban land 3. Retrofitting existing urban land 4. Intensive use of buildings 5. Housing form 6. Trip distance 7. Urban land cover 8. Trips using public transport 9. Proximity to public transport 10. Matching jobs and homes 11. Matching local services and homes 12. Proximity to local services 13. Trips on foot and by bicycle 14. Public space and green areas 15. Transport energy use 16. Residential energy use 17. Affordability 18. Public service

11 Cities and Energy Sustainability Current study framework Objectives Make cities more resilient, and contribute to inclusive and sustainable growth thorough urban energy policy. Make cities more energy-efficient and energy self-sufficient by reducing energy consumption, and increasing energy production and storage within cities. Key Questions Why urban energy matters? How inclusive growth and resilience can be achieved through enhancing urban energy sustainability? What are the effective urban strategies for enhancing energy sustainability? How can energy sustainability of the cities be measured? Components of the study Analytical framework study Case study Policy recommendations Timeline 2014: Background paper draft including urban energy trends 2015: Report draft including policy recommendations, and Workshop (tbc)

12 Outline of contents (Draft) 1. WHY URBAN ENERGY MATTERS? Resilience of cities Response to the environmental issues Economic aspects of urban energy 2. WHAT SHOULD BE CONSIDERED IN URBAN ENERGY? Energy trends of cities Characteristics of the cities and energy Tools for urban energy efficiency and energy self-sufficiency 3. POLICY PRACTICES (Case studies) Energy trends in the city, Characteristics of energy consumption and production of the city, Challenges and opportunities of urban energy, Urban energy policy practices, and Governance and organizations, etc 4. POLICY RECOMMENDATIONS Effective strategies to enhance energy sustainability of cities (e.g. Effective for different levels of spatial units, Governance, the way to measure energy sustainability of cities) 12

13 WHY URBAN ENERGY MATTERS? Urban areas have large impacts 80.0% Population and GDP in the metropolitan areas 70.0% 68.8% 69.4% 60.0% 50.0% 48.2% 54.1% 52.7% 57.4% 44.4% 40.0% 36.2% 30.0% 20.0% 10.0% 0.0% OECD ASIA North America Europe number of metropolitan areas Population Metropolitan areas: metro areas with a population of 500,000 or more GDP

14 WHY URBAN ENERGY MATTERS? Cities will consume more energy Mtoe 14,000 Estimated energy demand in cities Cities as a % of world 75% 12,000 73% 12,374 70% 69% 10,000 67% 9,785 Energy demand 65% 8,000 6,000 4,000 2,000-7,908 Energy demand 3,198 49% Urban population (million) Energy demand 54% 3,927 Urban population (million) 4, (Population: 2005) % Urban population (million) Source: Energy data from IEA (2008), Population data from UN population database (2011) Note: Calculated by the data including US, EU, Australia, New Zealand, China, Tokyo and Moscow 60% 55% 50% 45%

15 WHY URBAN ENERGY MATTERS? Resilience of urban energy Great East Japan Earthquakes One of the urban block in Tokyo provided electricity to the electric power company. Wide area power failure by Great East Japan Earthquakes; March 11, 2011 Power failure ratio by prefecture

16 WHY URBAN ENERGY MATTERS? Response to the environmental issues Apparent southward shift of European cities due to climate change ( ) Source: OECD (2010), Cities and Climate Change

17 WHY URBAN ENERGY MATTERS? Economic aspects of urban energy OECD - Indices of real energy prices for end-users, (base year 2010) OECD OECD Europe USA Japan Source: Data from IEA (2014), Energy prices and taxes quarterly statistics first quarter 2014

18 WHAT SHOULD BE CONSIDERED? Characteristics of the cities and energy CO2 emissions from ground transportation in large metropolises

19 WHAT SHOULD BE CONSIDERED? Energy trends of cities Energy data at city level (examples) Tokyo (Japan) (2010) Güssing (Austria) (2010) Population 13,161,751 4,337 Energy consumption (TJ) 723, Energy consumption per capita (GJ/capita) Energy production (TJ) 4, Energy production per capita (GJ/capita) Energy self-sufficiency 0.7% 71.0% Source: Own calculation based on the documents of Tokyo metropolitan government and Güssing 19

20 WHAT SHOULD BE CONSIDERED? Tools for urban energy efficiency and energy self-sufficiency Factors to be considered for sustainability of urban energy (examples) Innovation Energy consumption, conservation Energy production Energy storage Energy management Characteristics of the cities Natural environment Urban density Size of the cities Industrial structure Energy consumption structure Energy supply and production structure Spatial units Regions FUA Cities Districts 20

21 Collaboration between IEA and OECD (ideas) Inputs and exchange of information How can energy consumption and energy production at city level be measured? e.g. by sectors, by fuel types and units of measurement How can development and innovation of increasing energy efficiency of the cites be encouraged? How can public sector and private sector including energy producers collaborate for enhancing sustainability of urban energy? Knowledge sharing and networking etc Collaboration in the events including workshops Sharing best practices 21
