A Perspective on the Legal Uniformity of Aviation Carbon Costs Under CORSIA and EU ETS: Are Some Emissions More Equal than Others in the Current Scenario?

Must EU ETS and CORSIA carbon costs be identical across airline business models? This paper finds a per-tonne uniformity to be legally well-grounded and no right to deductions for connections, shipped cargo, multi-class cabin configuration, special services, or tankering procedures, while the geography involved does already differentiate costs. It then asks whether narrow, service-based credits for carrying passengers with reduced mobility and other special services should exist.
