What these figures can and can't tell you
This page shows figures side by side; it does not say that one product is better than another, and a carbon footprint alone cannot support such a claim (ISO 14044 §4.4.5, ISO 14067 Annex A). Screening estimate from listing data: not an ISO 14067-conformant study (no company data, no critical review) and not for marketing or comparative claims. Climate only: other environmental impacts are not assessed, so a lower figure does not mean a lower impact overall. Differences smaller than the uncertainty range on each product page are not meaningful. Method: ISO 14067 and PACT v3, see How it works.
