ABSTRACT

The allocation of responsibility for greenhouse gas (GHG) emissions – and, hence, climate change – is an important global policy debate. Indeed, the importance of responsibility is explicitly recognized in the United Nations Framework Convention on Climate Change (UNFCCC) allocation of ‘common but differentiated responsibilities’ among countries for addressing emissions.1 As shown in Chapter 1, urban areas – which are now home to more than half of the world’s population – clearly have an important role to play in facilitating reduced emissions; yet the contribution of urban areas to emissions is often unclear.
