Abstract

Greenhouse Gas (GHG) emissions are the main driver of global climate change, impacting ecosystems, economies, and societies. In Brazil, these emissions stem from agriculture, land-use change, the energy sector, and industrial processes. Despite the extensive data from SEEG, the lack of structural analysis linking states and sectors hinders the identification of inter-regional and intersectoral patterns. This work models these interactions using bipartite networks, analyzing structural and temporal patterns from 1973 to 2022. The results indicate a transition from industrial centers to agricultural and energy regions, contributing to more efficient public policies.
