More Than Just Carbon: Waste and Supply Chain Metrics Matter Too

Written by Jack Linnett (Co-founder & CEO)

Waste and supply chain metrics build trust that carbon alone cannot. Modern sustainability demands a full picture to avoid credibility gaps and unlock real opportunities.

Carbon's Headline Bias

Carbon dominates headlines, but focusing solely on it tells only half the story. Waste remains highly visible to customers through packaging and recycling, while supply chain—often 70–90% of emissions via Scope 3—carries the heaviest regulatory and impact weight. Selective carbon reporting risks perceptions of cherry-picking.

Why Waste and Supply Chain Matter

Customers experience waste daily; mismatched claims erode trust instantly. Supply chains drive outsized emissions, drawing regulator scrutiny and investor demands for transparency. Comprehensive metrics reveal faster wins: waste reduction cuts costs quickly, and supply chain engagement boosts reputation beyond CO2 efforts.

Full Picture Builds Credibility

Stakeholders—investors, NGOs, shoppers—expect holistic views. Boards gain context for strategy, comms teams craft regulator-safe narratives, and brands differentiate through verifiable breadth. Trust emerges from integrated progress, not single-metric spotlights.

Measure Beyond Carbon

Carbon starts the conversation; waste and supply chains complete it. Show performance across all fronts to earn lasting credibility.
