Sustainability Language
Attitude-behavior gap
The persistent discrepancy between people's stated pro-environmental attitudes and their actual purchasing and consumption behaviour.
Definition
The inconsistency between what consumers say they value — sustainable, ethical, environmentally friendly products — and what they actually buy and do. Surveys regularly find 30–50% of consumers expressing intent to buy sustainably, while market shares of such products often remain below 5%.

Overview
What it means
Research explains the gap through psychological barriers (price sensitivity, convenience, habit and low-involvement "system 1" decision-making), situational constraints (availability, information overload, distrust of labels after greenwashing experiences) and measurement artefacts such as social desirability bias in surveys. Models distinguish attitude–intention and intention–behaviour sub-gaps.
How it is used
Marketers, behavioural scientists and policymakers use the concept to design interventions — default options, credible labels, price signals, product redesign — that close the gap rather than assuming attitudes will translate directly into demand. It also cautions against reading survey enthusiasm as a market forecast.
Why it matters
Sustainable consumption strategies that ignore the gap overestimate demand for green products and underinvest in structural change. The gap is a central reason why information-based campaigns alone rarely shift consumption at scale.
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.
