Global Cities and their Response to Climate Change

Decision-makers in cities have realized their pivotal role in addressing climate change, and they are responding accordingly. This thesis presents three papers that explore the process of responding to climate change in cities, highlighting the situation in selected global cities with varying economies and development priorities. The methodology for conducting an urban greenhouse gas inventory in three Chinese cities is detailed in the first paper, illustrating issues of economic development and climate change mitigation in a transitional economy. Next, the greenhouse gas emissions savings of various strategic mitigation plans are quantified for Toronto, demonstrating the aggressive actions needed in developed cities to approach carbon neutrality. The third paper explores issues associated with climate change in three developing cities, emphasizing the need for synergic development incorporating strategies for both mitigation and adaptation. The thesis concludes with an overview of the importance of innovation and further research to future responses to climate change.
