Economic Slowdown or Decarbonization? Understanding Brazil’s Emission Pathways Through IPAT Decomposition

This commentary discusses Brazil's GHG trends focusing on the pre-and post-2015 Paris Agreement periods.The evidence in this perspective piece indicates that since 2015, Brazil's slowdown in carbon dioxide (CO₂) emissions growth has been driven mainly by weaker gross domestic product (GDP) per-capita growth rather than an acceleration in carbon-intensity gains.The Kaya identity decomposes CO₂ into four multiplicative drivers: Population (P) × GDP per capita (A) × Energy intensity of GDP (E/GDP) × Carbon intensity of energy (CO₂/E).The last two are summarized as carbon intensity (T), or emissions per unit of activity.Changes in total emissions thus come from demographic expansion, income growth, and technology or structural shifts that may reduce the carbon required to produce a unit of output.
