Intertek has met its near-term SBTi emissions targets early with verified 54.7% absolute reductions in Scope 1+2 by 2025. However, Scope 3 disclosure remains narrow—only 3 of 15 categories quantified—and critical supply chain emissions unquantified. Water, waste, and biodiversity lack measurable data. A greenwashing enablement controversy via its CarbonZero certification service undercuts credibility.
Intertek scores 41/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Scores are free. Nobody can pay to change a score, speed it up or hide it. Last verified August 2026.
That places Intertek joint 390th of 1,023 companies scored, and joint 24th of 30 in Consulting / Professional Services.
