The Challenge

M&S needed to scale its refill program despite traditional LCA processes being time- and cost-intensive, a lack of standardized comparative data to demonstrate the net environmental benefit of reuse, and a need for ISO-compliant outputs to support transparent marketing and reporting.

The Solution

CarbonBright's AI-powered platform ran cradle-to-grave assessments across multiple SKUs rapidly, modeled varying usage and reuse scenarios to generate comparative impact data, and produced audit-ready outputs aligned with ISO 14040, 14044, and 14067.

The Results
  • 10x faster LCA turnaround than traditional workflows
  • Environmental breakeven reached after just 2 reuses of aluminum refill containers
  • ISO-compliant, audit-ready reports strengthened transparency and stakeholder trust
  • Faster refill program rollout backed by data-driven insights
