Input–Output Subsystems: Agro-Industrial CH4 and Services CO2 Emissions in Uruguay

This paper analyzes methane emissions of the agro-industrial subsystem and carbon dioxide emissions of the services sectors subsystem in Uruguay in 2004. The relationship of these subsystems with the rest of the economy is analyzed through input–output methodology employing a multiplicative decomposition. This is combined with an additive decomposition for the study of the linkages within them. This approach allows us to study the importance of these subsystems as units in the economic structure as well as to analyze in detail the relationship between the different branches in each of the subsystems. The results depict in which sectors mitigation policies are more effective, and if they would be better tackled through technical improvements and better practices, or through demand policies.
