Why TUI Group lands here

One of the clearest real-world contrail-avoidance programs.

0best in the world: 78.5100

That is 4.2 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 TUI Group 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.

Where the points are

25.7 of the 100 points are still on the table for TUI Group. The three largest sit here:

  • 7.0

    SAF deployment and market-building

    18.0 of 25 earned

  • 6.5

    Customer participation, checkout donation, and sustainability access

    3.5 of 10 earned

  • 3.0

    Fleet efficiency and operational decarbonization

    9.0 of 12 earned

  • SAF deployment and market-building

    SAF

    18.0 / 25

    rough grade 4 of 5Bevidence ×0.907.0 points still available

    The airline shows real SAF activity through use, procurement, or market-building rather than long-dated ambition alone.

  • Contrail avoidance and non-CO₂ action

    Contrails

    22.5 / 25

    rough grade 4.5 of 5Aevidence ×1.002.5 points still available

    TUI reported 526 contrail avoidance flights in 2025 and framed contrail avoidance as an operational program, not a theoretical concept.

  • Fleet efficiency and operational decarbonization

    Ops

    9.0 / 12

    rough grade 4 of 5Bevidence ×0.903.0 points still available

    Fleet renewal and operating-efficiency work are visible and material.

  • Climate governance and transparency

    Governance

    8.7 / 10

    rough grade 4.5 of 5Aevidence ×1.001.3 points still available

    Public reporting is strong enough to compare targets, governance structure, and climate claims across reporting cycles.

  • Customer participation, checkout donation, and sustainability access

    Customer

    3.5 / 10

    rough grade 5 of 5Eevidence ×0.356.5 points still available

    Customer-facing sustainability participation is less developed than at the best booking-path leaders, which caps this pillar despite TUI's climate strengths elsewhere.

  • Ground operations, waste, and circularity

    Ground

    3.6 / 6

    rough grade 3 of 5Aevidence ×1.002.4 points still available

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

  • Community and nonprofit investment

    Community

    4.2 / 6

    rough grade 3.5 of 5Aevidence ×1.001.8 points still available

    Community or nonprofit support is visible and quantified rather than symbolic.

  • Climate advocacy and sector collaboration

    Advocacy

    4.8 / 6

    rough grade 4 of 5Aevidence ×1.001.2 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.
  • B×0.90Good disclosure with small limits.
  • 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 TUI Group overall is rated high.

We can tell you which points are cheapest to win

Two of the eight areas, booking-path participation and published uptake, are the ones our own real-money research speaks to directly: a redesigned donation step roughly doubled giving across three carriers, with no cost in brand favorability or booking intent.
