“…To help fill this gap, this assessment reviewed studies that focus on urban-scale GHG abatement or which could be applied at the urban scale. Although several city-specific studies exist (Bioregional and the London Sustainable Development Commission, 2009;Gomi, Shimada, & Matsuoka, 2010;Hickman et al, 2011;Lazarus et al, 2013;Phdungsilp, 2010;Zhang, Feng, & Chen, 2011), they generally do not use consistent methods or assumptions as each other, and it is difficult to determine whether abatement potential in one particular city could be broadly applicable across cities. As a result, to develop a globally consistent set of abatement potential estimates for urbanscale technologies and practices, we relied first on widely cited international studies of global GHG abatement potential, especially the International Energy Agency's Energy Technology Perspectives (IEA, 2012a).…”
