How we verify

The method behind every badge is public. Here is how we tier businesses, score sustainability, and keep the data honest.

Three trust tiers

Every listing carries exactly one badge, reflecting how far we have checked it. Badges are never mixed with paid placement.

Listed
Listed
A real listing with basic details checked for existence. No sustainability score yet.
Documented
Documented
The business has at least one registry-confirmed certification, or a published ESG report.
Verified
Verified
An externally assured ESG report, or two or more registry-confirmed credentials.

Badges are auto-recomputed and never bought: they reflect verifiable signals, not a paid plan.

The 4-pillar rubric

Each pillar is scored 0 to 3. We publish no single blended average: each pillar stands on its own so you see genuine strengths and weaknesses, not one number hiding them.

Pillar What it measures
EnvironmentEnergy, emissions, water, waste, materials and impact on biodiversity.
SocialLabor conditions, safety, local community, and supply-chain fairness.
GovernanceOwnership, business ethics, compliance and accountability.
TransparencyHow openly the business discloses evidence, and whether it can be verified.
Score Meaning
0No evidence, or an unsupported claim.
1Early: a stated commitment and first signs of action.
2Solid: consistent practice with public evidence.
3Leading: independently verified results, improving over time.

Data provenance & community flagging

Every listing records where it came from: self-submitted, claimed by its owner, or compiled by the ViCo team. Expired certifications stay visible for transparency, but the badge they earned is dropped.

Anyone can report inaccurate information or greenwashing directly on a listing. Each report opens a review ticket for a staff member to re-check.

Verification is never for sale

Businesses can pay for visibility: featured placement, a richer profile, a sector banner. No one can pay to be verified or to raise a sustainability score. If that were for sale, the badge would mean nothing.
