Wizz Air argues that business class should be banned from all short-haul flights, as business class travelers have twice the carbon footprint of those in economy class.

Currently, Wizz Air’s emissions per passenger are the lowest of all its competitors, at 57.1 g/passenger/km, according to November 2019 figures. The company’s ultra-discount business model, high flight saturation (95% in the first half of 2020), and efficient cabin design allow for sustainable flight and low carbon emissions.

Over the next 10 years, emissions per passenger would be cut by an additional 30%, says forbes.hu.
