Urban areas contribute significantly to global greenhouse gas (GHG) emissions, in particular carbon dioxide (CO2), with some estimates suggesting this contribution may be as high as 80 percent.

Abstract

Urban areas contribute significantly to global greenhouse gas (GHG) emissions, in particular carbon dioxide (CO2), with some estimates suggesting this contribution may be as high as 80 percent. This reflects the concentration of people and economic activities in urban agglomerations and the high levels of energy consumption associated with residential, production, and mobility needs. The negative externalities associated with congestion and pollution tend to increase with urbanization. Nevertheless, in most cases, major cities have lower per capita CO2-equivalent emissions (CO2e) than at the corresponding national level. As cities assume a higher profile in the area of climate change, many are recognizing the potential to reduce emissions and are committing to voluntary reduction targets. In the last 20 years, many cities in industrialized countries have developed climate change plans. More recently, cities in developing countries have followed suit, as in the cases of Mexico City and Bangkok. The analysis is structured in four main sections: the first compares inventories across cities according to criteria applied to collect and organize data, the second analyzes the emissions context of each city through a set of indicators, and the third compares the main components and measures of each city’s mitigation plan. The last section draws some conclusions with regard to the coherence, effectiveness, and efficiency of city mitigation plans.
