Method v1.0 · preliminary

How we score

Each product gets a score from 0 to 100, built only from documents the manufacturer or an independent certifier published. We score each barcode separately, because sheens and bases can differ.

75–100 Excellent50–74 Good25–49 Poor0–24 Bad
Indoor air (40)VOC under 5 g/L+15
VOC 5–50 g/L+8
Maker states tinting adds no VOC+10
Emissions tested (GREENGUARD, CDPH, LEED emissions)+15
Ingredient hazards (35)Start at 35, then for each Safety Data Sheet warning:
Cancer, genetic damage or reproductive warning for the paint itself−15
Cancer warning for dust only (titanium dioxide, silica, clays)−3
Skin or respiratory allergen−8
Organ toxicity or acute toxicity−8
Serious eye damage or skin corrosion−5
Aquatic toxicity, flammable, aspiration hazard−3
Transparency (15)Full ingredient list published (e.g. Health Product Declaration)+15
Environmental data sheet or partial disclosure+8
Safety Data Sheet only+3
Independent verification (10)Ingredient or health certification in the certifier's registry+10

Rules we never break

  • No estimates. If something isn't documented, it earns zero points and says "not disclosed."
  • No score without a current US Safety Data Sheet and a documented VOC figure.
  • A cancer, genetic damage or reproductive warning for the paint itself caps the score at 59.
  • Self-awarded seals don't count. Certifications are checked in the certifier's registry.
  • No brand pays for, sponsors or influences a score. Makers can send newer documents to correct a listing.

Scores are preliminary until our method completes independent expert review.
