Urban population distribution
• The environmental footprint of cities is far larger than their physical boundaries
• Atmospheric pollution : 60 – 70 % of global derived GHG emissions is from cities
• Local environment: high concentration of particulate matter is a danger to health– Annually 5.3% of the deaths worldwide (3.1
million) are attributable to air pollution. (WHO)

Environmental Impact of Urbanization
• Water: high levels of contamination where the population density is high and the sanitation standards are low
• Waste :1.7-1.9 billion tonnes, or 46 % of global waste
• Tools for measuring, reporting and verification of environmental data
• Urban CDM – with Gwangju
• Conducting city-level assessments: the GEO Cities series.
14
Working with the Building sector
• Sustainable Building and Climate Initiative (SBCI)– Over 18 private sector partners including big
companies all over the world – Advocating and developing a common voice for the
building sector together with a benchmarking system to assess the environmental performance of buildings
15
UNEP: Working with the Building sector
• Sustainable Social Housing Initiative (SUSHI)
• Sustainable Building Policies in Developing Countries (SPoD)
16
Key Strategic Partnerships
• Support local authorities and the building sector stakeholders and establish networks of cooperation
• Incorporate resource efficiency into urban policies and design
• Promoting common tools for city/buildings environmental data and assessment.

Summary of UNEP’s approach
Towards Rio + 20Elements of a Global Initiative on Cities
• Platform for consultation and for sharing best practices among city managers/urban planners
• Developing common metrics for sustainable cities, (e.g., for GHG emissions, city environmental performance assessments, Common Carbon Metric in the building sector, etc)
• Promote clean energy and energy efficiency and to support technology transfer and climate finance
Towards Rio + 20Elements of a Global Initiative on Cities
• Mainstreaming mitigation/adaptation concerns into development policies and plans • Low carbon mobility and sustainable transport• Switching to green building practices through the
adoption of building energy codes
• Successful implementation of waste and water management policies• Strengthen legislation to secure water quality• Utilize economic instruments• Implement the 3Rs in waste management• Change consumption patterns to avoid waste
generation
Towards Rio + 20Elements of a Global Initiative on Cities
• Promote planned growth• Advocate public participation and
Incentives for relocation)• Adopt sustainable land management
• Upscale efforts on protected area expansion and species conservation
