The Unassuming Economist

From a paper by Claudia Amadei, Cesare Dosi & Francesco Jacopo Pintus:

“Declines in the energy intensity of national gross domestic product cannot be simply taken as evidence of a country’s contribution to global decarbonization, notably when they come from structural changes that relocate energy-intensive production abroad. Here we analyze the role of offshoring in shaping energy intensity trends in a panel of 15 countries of the Organisation for Economic Co-operation and Development between 1970 and 2021. Using both a decomposition analysis and a structural econometric model, we show that shifts in the composition of national output not mirrored by equivalent changes in domestic consumption patterns significantly and persistently reduce national energy intensity. These findings support the need to move beyond production-based climate metrics and to incorporate global supply chains for a more reliable assessment of national decarbonization pathways.”
