The Scope 3 Challenge: Why Indirect Emissions Are the New Brand Risk

Written by Jack Linnett (Co-founder & CEO)

For most companies, Scope 3 isn’t just the biggest part of their footprint — it’s the hardest to measure.

📊 On average, 70–90% of total emissions come from Scope 3: suppliers, logistics, product use, and end of life.

⚠️ That makes it the biggest blind spot in sustainability reporting — and the fastest-growing source of regulatory and reputational risk.

The challenge:
- Supply chains are complex and global
- Data is inconsistent and often incomplete
- Customers and investors still expect clarity

The risk:
- Overstating progress if Scope 3 is ignored
- Greenwashing accusations if claims lack evidence
- Missed opportunities to cut emissions where they matter most

Scope 3 is complicated. Your messaging doesn’t have to be.

At Earthmark, we:
✅ Quantify Scope 3 data and benchmark it against sector peers
✅ Structure it into clear, customer-safe proof points
✅ Translate complexity into language stakeholders understand — without losing legal substance

Because the new brand risk isn’t just failing to act on Scope 3. It’s failing to explain it.

👉 Are your Scope 3 disclosures building trust — or creating risk?
