Abstract
This paper applies the ecological footprint method to the Brazilian economic input-output (IO) model. The footprint method calculates the amount of land required to support economic activities and absorb the wastes they generate. In the case of IO models, the footprints are allocated to sectors corresponding to distinct activities within the economy. The Brazilian IO table is available from the Instituto Brasileiro de Geografia e Estatística (IBGE). The footprint assessment, which is used as a basis for this study, is available from the Global Footprint Network (GFN). The IO-footprint model is produced in a spreadsheet, which allows the user to trace back the assumptions and data sources used to build the model. The analysis determines the ecological footprint intensity of 42 Brazilian economic sectors and can be used to develop more sustainable manufacturing processes. The assessment’s results show which sectors have
the greatest footprint based on per R$ 1 million and their total annual output. The dairy products industry has the highest footprint per R$ 1 million of final demand, whereas the steel mill sector has the highest footprint when the total annual industrial output of each sector is considered. The model construct may be used to identify the sectors that contribute the most to the final footprint of each industry. This information is a starting point for companies concerned with sustainable manufacturing and interested in the life cycle assessment of their products and services.
