Why United Airlines lands here

Best overall mix of SAF scale, customer participation, and disclosure.

0best in the world: 78.5100

That is 2.7 points behind the best-scoring carrier in the world, which itself only reaches 78.5. No carrier reaches 80, and 13 of 32 score below half marks.

What this score is built from

Eight decision areas, weighted by what moves emissions now

Each area is graded against what United Airlines publishes, then scaled by how well that work is evidenced. Contrail avoidance carries the same weight as sustainable aviation fuel, because both are available today.

    SAF

    23.0 / 25

    rough grade 4.5 of 5Aevidence ×1.002.0 points still available

    Contrails

    10.0 / 25

    rough grade 2 of 5Aevidence ×1.0015.0 points still available

  • Climate governance and transparency

    Governance

    9.3 / 10

  • Customer participation, checkout donation, and sustainability access

    Customer

    8.6 / 10

    rough grade 4.5 of 5Aevidence ×1.001.4 points still available

  • Ground operations, waste, and circularity

    Ground

    3.9 / 6

    rough grade 5 of 5Devidence ×0.652.1 points still available

    There is some evidence of ground or waste action, but the public detail remains limited.

  • Community and nonprofit investment

    Community

    5.4 / 6

    rough grade 4.5 of 5Aevidence ×1.000.6 points still available

    United discloses unusually concrete community figures, including cash, in-kind, employee, and customer-supported giving.

  • Climate advocacy and sector collaboration

    Advocacy

    5.4 / 6

    rough grade 4.5 of 5Aevidence ×1.000.6 points still available

    The airline is visibly engaged in sector collaboration, policy work, or broader climate signaling beyond internal operations.

Evidence codes

  • A×1.00Current quantified disclosure or clearly documented live program.

  • C×0.80Older-cycle, group-level, proxy, or incomplete quantified evidence.
  • D×0.65Fragmented or partial proxy evidence.
  • E×0.35No credible public evidence; floor only.

Grades are recorded to the nearest half point, so the published pillar score is the authoritative figure and the grade is a rounded description of it. Evidence quality for United Airlines overall is rated high.
