Shoppers believe specifics. Everything else reads as greenwash

The easy green era is over

Years of vague eco-labels trained shoppers to squint. Add regulators fining fuzzy claims, and “eco-friendly” on pack is now a liability unless you can prove it. The research question shifted from “do they care?” to “which exact claim do they believe — and pay for?”

What holds up in testing

• Specifics beat slogans: Verified numbers — recycled share, repairability scores — outperform generic green language.
• Price still bites: Stated green intent fades at the till. Use trade-off methods to find real willingness to pay.
• Category rules differ: Sustainability decides some purchases and barely registers in others. Test per category.
• Age myths mislead: Young buyers voice more concern but don't automatically pay more. The attitude–behavior gap is ageless.

Ask with trade-offs, not ratings

Direct “how important is sustainability?” questions flatter everyone. Conjoint and MaxDiff force choices between price, convenience, and green attributes — that's where true priorities show. Then claims-test the winning messages before media spend.

It's compliance work too

Under EU green-claims rules and copycats elsewhere, unproven messaging risks fines, not just eye-rolls. Pre-launch claims research doubles as legal cover. Budget it like that.
