Integrating learning from the GHG accounting and MFA communities is essential to advance our understanding of urban sustainability. with horse manure and coal ash. In Europe, concerns about supplying materials to cities were discussed in the early 1900s, and continued (after a hiatus) into the late twentieth century from a new perspective of environmental impact, leading to the development of methods for economy-wide material flow analysis (MFA) and their application to cities (Barles 2010). This method, used in many current studies of urban metabolism, allows for tracking of material inputs, changes in stock, export of goods, and release of waste and pollution; indirect material requirements to support these flows can also be computed. While the MFA methodology also draws on energy analysis and is considered to be readily adaptable to include energy, in practice there is wide variation in the inclusion of embodied energy components. At the start of the 21st century, concerns about climate change prompted several U.S. cities to adopt the U.S. Mayor’s Climate Protection Agreement,1 and cities began implementing community-wide urban energy studies in a bottom-up manner for greenhouse gas (GHG) accounting (Bailey 2007).2 Mayors in the European Union (EU) adopted similar covenants by 2011.3 Through organizations such as ICLEI,4 such city-scale GHG accounting efforts spread worldwide, including to cities in the developing world. In the early years, cities took a boundary-limited view, tracking community-wide use of electricity, natural gas, and
