Case Study: Zayo builds an accurate emissions inventory for 49,000+ global sites with Optera

Zayo reduces verification time by 4 weeks with Optera

Zayo, a leading provider of communications infrastructure services, faced the significant challenge of building its first greenhouse gas (GHG) inventory for over 49,000 global sites. A major hurdle was the lack of utility bill data for approximately 45,000 of these locations. To establish a baseline for science-based targets and reporting, Zayo enlisted the expert services of Optera to help navigate this complex data collection and calculation process.

Optera collaborated with Zayo to form working groups, creating tailored models for emissions estimation where actual data was unavailable. This partnership enabled Zayo to complete a verified inventory. The results were substantial: Zayo improved its CDP climate score from a D to a B, reduced third-party verification time by four weeks, and received SBTi validation for its net-zero by 2045 target. Optera's ongoing support was crucial to these achievements.
