Absolute decoupling
Definition
Decoupling is absolute when an economic driving force (such as GDP) grows while the associated environmental pressure (such as greenhouse gas emissions or resource use) is stable or declining. It contrasts with relative decoupling, where the pressure still rises but at a slower rate than the economy (OECD usage since 2002).

Overview
What it means
OECD work formalised decoupling indicators comparing growth rates of environmental pressures and economic drivers; absolute decoupling has been observed for some pressures in some countries (for example sulphur oxide emissions in OECD economies), while relative decoupling is far more widespread.
Analysts caution that meaningful climate decoupling must also be total (all emissions, including consumption-based), global, sustained over time and fast enough for climate targets.
How it is used
Governments, the OECD and researchers use decoupling indicators to assess green growth claims and environmental performance. Debates over whether absolute decoupling of material use and emissions is achievable at global scale feature prominently in green-growth and post-growth literature.
Why it matters
Climate stabilisation requires emissions to fall in absolute terms, not merely grow more slowly than GDP. Evidence of sustained, global, absolute decoupling of emissions and material throughput remains limited, which is why the term carries so much weight in sustainability strategy debates.
Definitions and controversy
Territorial accounts can show national absolute decoupling while consumption-based (footprint) accounts do not; the feasibility of worldwide absolute decoupling at sufficient speed is contested.
