Abstract: This project sets out to determine the total material requirement of the City of York using a ‘Material Flow Analysis' and then to calculate the Ecological Footprint associated with the consumption of these materials. Taken together, these indicators can provide a comprehensive framework for understanding the various pathways that the City could take in order to move towards sustainability as well as enabling the more effective communication of ideas about sustainable lifestyles to the City's residents.

Executive Summary
1.
In November 2001, the Stockholm Environment Institute at York (SEI-Y), based at the University of York, initiated a study to measure the quantity of food and materials that the residents of York consume annually and to determine the resultant ‘ecological footprint' - a measure of the City of York's impact on the local and global environment. The study was funded by Norwich Union and was produced as a contribution to the Energy Saving Trust's ‘Planet York' campaign and the City of York's Local Agenda 21 - Better Quality of Life Strategy.

The purpose of a material flow analysis (MFA) is to follow and quantify the flow of materials in a defined situation and over a set period of time. The end products of the MFA for York are detailed input-output tables showing the flow of all materials associated with non-industrial consumption that entered and left the city during the year 2000. These materials include the weight of fuel (the ‘energy carriers') required to produce the consumption items and bring them to York, to build York's infrastructure, to provide domestic heat and lighting, for personal transportation and so forth. Also accounted for are the ‘hidden flows' of materials that do not enter the economy for example, the removal of overburden during mining or waste trimmings from forestry.

While MFA provides valuable information concerning the total throughput of materials within York, the ecological footprint provides an understanding of the environmental pressures of these material flows. It considers the amount of productive land and water ecosystems in hectares (ha) that York requires to provide the goods and services that it consumes and to assimilate the wastes that it produces. Some of this land will be found within York itself while the rest will be in other countries and continents. The footprint includes the notional forest land area that would be required to sequester the carbon from carbon dioxide (CO 2) emissions (and emissions of other major greenhouse gases (GHGs) converted into CO2 equivalents) due to fossil fuel combustion. The study focuses on energy use; food, food packaging and food miles; housing, non-food consumables, waste, transport, water supply and other infrastructure....
