No. Payment covers the assessment process, not the outcome. The rubric is public. The same ten questions are applied to everyone. A company that submits evidence of rising emissions and no targets will still score low.
Public scores are based only on what’s publicly available. Many companies, especially SMEs, have strong sustainability practices that aren’t documented online. The Enhanced Assessment lets you submit that evidence so your score reflects your full picture — not just what Google can find.
Challenge any question with evidence — it’s free. If your evidence supports a different score, we’ll update it. All changes are logged publicly. You don’t need to pay to challenge a score.
Free public scores are generated within 24 hours. Enhanced assessments take 3–5 working days after you submit your evidence.
Possibly — but that’s a disclosure gap, not a judgement on your practices. A 50-person manufacturer might have excellent environmental practices but score 25 because none of it is documented publicly. The Enhanced Assessment exists for exactly this — submit your actual data and your score will reflect what you’re really doing.
