Wizz Air reports verified Scope 1/2 emissions and multi-category Scope 3 data, but absolute emissions are rising as the airline expands its fleet toward 500 aircraft by 2030. The 25% intensity-reduction target by 2030 is unvalidated, intensity-only, and showing stagnation. An upheld UK advertising ruling in November 2024 banned claims of being 'one of the greenest' as misleading.
