Wizz Air is Europe's fastest-growing aviation polluter, with absolute emissions up 40% since 2019 despite intensity gains. The airline relies entirely on jet fuel, has no meaningful renewable energy strategy, and was caught greenwashing by UK regulators. Growth plans to 500 aircraft by 2030 guarantee further emission increases.

The airline competes on ultra-low fares and has become one of Europe's largest carriers by fleet size.
Direct competitor in European ultra-low-cost carrier segment; similarly exposed to greenwashing and intensity-only targets.
