Abstract
Environmental impacts of cities are a growing concern because of the expanding
population, growing demand of natural resources and production of pollutants to
the environment. The urban metabolism concept stands on the basic ground that
all the movement or flow of materials within an urban system can be accounted
systematically. The Economic Input–Output analysis method is applied to the
city of Barcelona, Spain as a system boundary to estimate the materials and
energy resources required for and the environmental emissions resulting from
activities in the economy. Economic input–output analysis is used as an
approach to analyze a town metabolism with a demand-based approach. Many
inputs and outputs ranging from residential, transportation, consumptions and
services can be looked upon in the urban system. Some of the resulting impact of
a city are not always immediate and direct, therefore only a complete
examination of the urban system could observe those resulting impacts. Through
urban metabolism approach, decision are hoped to be made in a more deliberate
and systematic way. Limitation to the practice of urban metabolism via
economic input–output analysis such as lacking of local and regional data is also
addressed.
Keywords: urban metabolism, economic input–output analysis, greenhouse
gases emission intensity, Barcelona.
