Below expectationsPending Review

Tortilla Mexican Grill has published minimal sustainability data since its 2022 ESG report. No Scope 1, 2, or 3 emissions figures disclosed; a 2022 SBTi net zero commitment shows no follow-through. Claims 100% renewable electricity and zero waste to landfill lack third-party verification. Expansion from 84 to 120+ sites means absolute emissions are rising unmeasured.
