LinkedIn Post 10: CBGA-DISAGGREGATE: Building-Level Transparency
Your portfolio is 12% more efficient than last year. Compliant. On track.
But your buildings are not.
Portfolio-level aggregation is useful for climate impact reporting and board-level communication. But it's dangerous as a governance mechanism. It hides individual building non-compliance behind portfolio averages.
CBGA-DISAGGREGATE requires building-level carbon outcome reporting alongside portfolio-level figures. Each building gets:
An explicit carbon budget allocation for the budget period
Tracked progress toward that allocation
A compliance status (on-track, at-risk, non-compliant)
Individual accountability
This makes non-compliance visible. It prevents buildings from being hidden in the average. And it forces a conversation: which buildings are falling behind, and why?
Most organisations don't do this. It's uncomfortable. It requires facilities teams to own building-level targets, not just portfolio targets. But it's the only way to ensure your governance is real, not illusory.
