easyJet scores 1 point higher than Ryanair on SINK's sustainability index.
easyJet is more sustainable according to SINK's open sustainability index, scoring 24/100 vs Ryanair's 23/100 — a difference of 1 points.
Ryanair scores 23/100 on the SINK sustainability index (Significant gaps). Ryanair's emissions are rising sharply while it claims climate leadership. Absolute CO2 grew 80% since 2022; intensity targets mask this reality. The airline relies entirely on fossil jet fuel, has minimal SAF uptake beyond EU mandates, and CEO O'Leary publicly undermines the company's own net-zero strategy. Multiple regulatory bodies have found misleading climate claims.
easyJet scores 24/100 on the SINK sustainability index (Significant gaps). easyJet reports robust emissions data with third-party verification, but absolute emissions rose 7.93% in FY2024 while the airline carried more passengers. Its SBTi target is intensity-based, not absolute reduction. The company faces multiple greenwashing allegations from regulators and NGOs, and has no meaningful renewable energy strategy despite being a fossil-fuel-dependent operator.
Both companies are rated on the same 10-question SINK rubric: Scope 1/2/3 carbon footprint, energy source, nature and biodiversity, resource use, water, emissions trajectory, science-based targets, transparency, and controversies. Scores are 0–100, based on public data, and fully reproducible.
