What is it about?

This paper synthesizes the evidence from a large body of empirical research on whether economic growth can be decoupled from resource use and greenhouse gas emissions. It reviews studies on energy, exergy, materials, CO₂ and total GHG emissions to assess how often relative or absolute decoupling has actually been observed, and under what conditions.

Why is it important?

This paper is important because it moves beyond mapping the literature and asks what the evidence actually shows. Its main conclusion is that while relative decoupling is common, absolute decoupling at the scale and speed needed for climate and sustainability goals is rare. It argues that observed decoupling trends are not enough on their own, and that they need to be complemented by sufficiency-oriented strategies and strict absolute reduction targets.
