easyJet scores 1 point higher than Ryanair on SINK's sustainability index.
easyJet is more sustainable according to SINK's open sustainability index, scoring 25/100 vs Ryanair's 24/100 — a difference of 1 points.
Ryanair scores 24/100 on the SINK sustainability index (Significant gaps). Ryanair's 20.1 Mt CO₂e footprint rose 7.8% year-on-year, driven by capacity growth to 300 million passengers by 2034. SAF remains negligible (2% from January 2025, meeting regulatory minimum only). An upheld ASA greenwashing ruling, ACM warning on offset claims, and documented climate lobbying deterioration—including CEO rejection of 2050 net-zero—undermine stated targets.
easyJet scores 25/100 on the SINK sustainability index (Significant gaps). easyJet publishes verified emissions data and holds an SBTi-validated intensity target, but absolute emissions rose 43% year-on-year while the airline remains 99%+ dependent on fossil jet fuel. Supply chain emissions are largely unmeasured, and recent regulatory findings and NGO warnings expose greenwashing in net-zero claims and offset reliance.
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.
