WE ZeroMarketing Decarbonization Certification
WE7 is the first company to certify marketing decarbonization. WE Zero is the recognized standard for teams that measure, reduce, and verify the carbon footprint of their marketing — from media spend to creative production to Scope 3 disclosure.
Why this matters now
Marketing is the last unmeasured carbon frontier. Every year, digital advertising alone generates over 60 million tonnes of CO₂e — yet no standard existed to certify teams actively decarbonizing it. WE Zero closes that gap.
Three certification levels
Every level is benchmarked against the Campaign Carbon Score (CCS) — a performance-weighted measure of marketing carbon intensity in gCO₂e per 1,000 impressions.
WE Zero — Verified
Baseline decarbonization
For teams that have measured their marketing carbon footprint, eliminated the highest-emitting waste, and committed to a public reduction roadmap.
- Annual CCS baseline established
- Top 3 waste channels eliminated
- Public commitment published
WE Zero — Leader
Active optimization
For teams running continuous, performance-weighted carbon optimization across every active campaign — with measurable, audited reductions year over year.
- Quarterly CCS audits
- YoY emissions reduction ≥ 20%
- Full Scope 3 marketing disclosure
WE Zero — Pioneers
Net-zero marketing
The flagship tier for marketing organizations operating at net-zero carbon — verified, audited, and third-party validated against SBTi-aligned targets.
- Net-zero verified marketing
