In terms of accounting for emissions decoupling, a recent study by the Breakthrough Institute (Hausfather, 2021) highlights that 32 countries have managed to demonstrate economic growth while CO2 emissions declined since 2005, even when accounting for emissions embodied in the goods consumed in a country. However, they note with caution that these economies are already wealthy-service driven economies and that very few examples are present from low- or middleincome countries based on extractive industries and energy-intensive manufacturing to date. While this study can present a departure narrative of consumption-based emissions and absolute decoupling as we switch to clearer technologies, we must not forget that extraction and resource dependence remain intact on the supply side – supplies and sinks being the two sides of the same coin of the decoupling phenomena.
