WE ZeroMarketing Decarbonization Certification
WE Zero is the first program that makes marketing decarbonization certifiable. It gives teams a rigorous, performance-based path to measure, reduce, and verify the carbon footprint of their marketing — from media spend to creative production to Scope 3 disclosure — with certification granted independently by the Global Network for Zero.
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 independent certification has ever verified a company's progress in 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 — and verified through independent review.
WE Zero — Verified
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
For teams running continuous, performance-weighted carbon optimization across every active campaign, with measurable, verified reductions year over year.
- Quarterly CCS reviews
- YoY emissions reduction of 20% or more
- Full Scope 3 marketing disclosure
WE Zero — Pioneers
The flagship tier for marketing organizations operating at net-zero carbon: verified, independently reviewed, and aligned with SBTi-informed targets.
- Net-zero verified marketing
- Independent third-party verification
- Pioneer registry listing
