Gatwick cut its Scope 1 emissions 34% since 2021, but its total reported footprint rose 1.4% in 2025 as reported aircraft emissions climbed. The Northern Runway expansion was approved despite the examining authority's warning that its emissions could materially affect UK carbon targets. Its net-zero claims rest partly on offsets and on renewable electricity certificates.

Gatwick's printed Scope 3 table for 2025 appears to be misaligned, with figures shifted by a row. We score the figures as printed, except the landing and take-off figure, which doesn't match Gatwick's own per-passenger figure and so isn't used. If Gatwick publishes a corrected table, we'll re-score.
