House factors versus sector materiality
How to reconcile your firm’s house ESG factors with sector-specific materiality when comparing listed companies.
House ESG factors protect consistency across a firm. Sector materiality protects relevance for a given listed company. An ESG factor comparison that ignores either side frustrates someone in the room.
Map, then explain overrides
Start by mapping house factors to the peer set. Where a house factor is weakly material for the sector — for example certain emissions intensity metrics for an asset-light software listing — say so and show the house factor anyway with reduced weight in the narrative, rather than dropping it quietly.
Elevate sector-critical factors
If every peer faces process-safety exposure, that factor deserves space even when the house list treats it generically under “social.” Call the elevation out so compliance teams see you did not invent policy.
Write for two readers
Compliance readers want the house list covered. Portfolio readers want the factors that could move the thesis. A good comparison pack serves both by using house-factor order in the table and sector narrative in the commentary.
A Leeds example
For a northern multi-asset desk comparing three listed utilities, we kept the firm’s biodiversity factor in the table while elevating water stress and network resilience in the executive page. Both audiences left with language they could defend.
