Making progressPending Review

Toast Ale demonstrates genuine circular economy integration and transparent governance, but emissions tracking shows backsliding: 187 tCO2e in 2024 versus 150 in 2023, a 25% increase undercutting credibility. Strong on supply chain visibility and nature partnerships; weak on energy strategy and water quantification. Net Zero 2030 lacks SBTi validation.
