The Intention-Action Gap: Why Good Intentions Don't Reach the Checkout
97% of people say they are prepared to act more sustainably. 13% actually change their behavior. The distance between those two numbers is the intention-action gap. It is the single most expensive and least examined line item in sustainable brand growth — and it's measurable.
An 84-Point Problem Nobody Has Priced
The Sustainable Marketing 2030 Report puts stated intent at 97% and behaviour change at 13%. NYU Stern's Sustainable Market Share Index shows sustainability-marketed products generating around a third of all CPG growth from under a fifth of market share.
Both things are true at once: the demand is real, and most of it never converts. Brands respond by spending more on communicating the commitment, which addresses the 97% who are already persuaded.
The gap does not close with more awareness. It closes by removing whatever specific barrier sits between belief and basket — and that barrier is different in every category.
THE FRAMEWORK
How We Measure and Close It
1. Size the gap
Determine how large your intention-action gap is, by category and by stage of the consumer experience journey — and how it compares to your competition. This is the 5C Landscape Assessment.
2. Locate the barrier
Identify where along the path to purchase intent is actually leaking: price, convenience, credibility, packaging legibility, or habit.
3. Build the intervention
Develop the content, messaging and tactics that close that specific gap — then test them.
4. Prove the behavior change
Measure the shift in purchase intent and behavior, not in recall.

Frequently Asked Questions
Research tells you what people say. Gap analysis measures the distance between what they say and what they do, then prices it.
Almost all of them do — that is the 97%. The commercially useful question is which of them act, and what stops the rest.
Frequently, and it is often the real blocker: a sustainability goal that never makes it from the ESG report into the brand plan.
The gap exists in every category we have measured; only its size and location differ. That is the finding, not the assumption.
The assessment is a sprint, not a study. You get a sized gap and a prioritised list of barriers, not a 200-page deck.
