Wingstop discloses only 50-restaurant Scope 1+2 emissions while operating 2,500+ locations. Scope 3 data is absent entirely despite chicken's material deforestation and water footprint. A 2024 shareholder resolution explicitly called out the absence of system-wide climate policy. Waste initiatives exist but lack verified targets.
Wingstop scores 35/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified May 2026.
That places Wingstop joint 482nd of 847 companies scored, and joint 20th of 49 in Food Service / Restaurants.

Its three lowest-scoring questions, and what the evidence didn't show.
2024 shareholder resolution stated Wingstop 'does not transparently provide any GHG emissions data from either its operations or supply chain.' Chicken wings rely on intensive poultry farming and soy feed—material upstream footprint unquantified and unaddressed.
Full-system trajectory likely rising in absolute terms.
No deforestation-free commitment, no TNFD disclosure, no nature policy, no supplier sustainability requirements.
