Absolute decoupling
A state in which an economy grows while the environmental pressure it causes falls in absolute terms — the form of decoupling that genuine green growth requires.
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.
Review
Public comments appear only after editor acceptance. Draft comments stay in the review queue.
Reviewers choose the definition or an overview paragraph, leave a comment or replacement, and attach evidence or a source link.
Editors compare reviewer cards side by side. AI may help find agreement, conflicts, unsupported claims and possible source issues.
Only an editor-accepted synthesis changes the public page. Reviewer identities are shown only with consent and an editorial decision to attribute them.
Submitted reviews stay private until an editor decides whether to accept and attribute them.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
