The environmental impact of cities goes beyond the impact on the health and well-being residents. Cities have a strong influence on the environment at the national, regional and global levels. The urban dimension of climate change, water, energy, biodiversity, chemical, wastes, trans-boundary air, and river pollution and pollution coastal areas, is becoming more and more evident. Recognizing this, UNEP and UN-HABITAT have started an iniciative to emphasise the link of local environmental issues and global policies.
