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.
