Decoupling, also referred to as dematerialisation of the economy, refers to the disconnection or separation of economic and social well-being from the use of biophysical resources. According to the MEFA (Material and Energy Flow Analysis) framework, decoupling may occur in at least three relations: (1) economic growth – as measured by GDP growth – may be decoupled from material and energy throughput (an increase in ‘efficiency’ leading to ‘dematerialisation’); (2) material and energy throughput, decoupled from social well-being (‘sufficiency’); and (3) social well-being, as it becomes decoupled from economic growth (‘equity’) (Haberl et al., 2004). This is shown in Figure 1.
According to Haberl et al. (2004), studies on the relation between economic growth and national material throughput reveal three patterns: (1) ‘no decoupling’; i.e. material throughput increased faster or as fast as GDP (see Eurostat, 2002); (2) ‘relative decoupling’, a situation where the amount of material or energy needed to produce USD1 of GDP declines over time – this be observed in many countries (see Eurostat, 2002; Fischer-Kowalski and Amann, 2001; Schandl et al., 1999); and (3) ‘absolute decoupling’ in the sense that the aggregate materials and energy throughput of an economy declines over time while GDP continues to grow. This has taken place in a few industrial economies such as Germany or the Netherlands (Eurostat, 2002), although trade patterns must be taken into account, because decoupling may be the result of outsourcing production of raw materials or energy-intensive production.
