TAP Air Portugal scores 27/100 (Significant gaps) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified July 2026.

That places TAP Air Portugal joint 636th of 790 companies scored, and joint 3rd of 9 in Aerospace.

TAP Air Portugal reports Scope 1 and 2 emissions but withholds Scope 3 data entirely. Absolute emissions rose post-COVID with no reduction targets set. The airline relies on regulatory SAF mandates, greenwashing offset schemes, and industry-wide net-zero 2050 aspiration rather than science-based near-term goals.
