Most materiality assessments start the same way: list a set of ESG topics, survey a handful of stakeholders, plot the results on a two-by-two grid, and call it done. The output looks rigorous. In practice, it rarely survives contact with a board that wants to know why "biodiversity" and "data privacy" landed in the same quadrant.
The problem isn't the topics — it's the assumption that every stakeholder's view should count equally. An investor's read on climate transition risk and a community group's read on local water use are both legitimate inputs, but they aren't interchangeable, and treating them as such produces a matrix that satisfies no one.
Weighting stakeholder input differently, based on influence, exposure, and proximity to the business, is what turns a materiality assessment from a compliance checkbox into a genuinely useful strategic input. It also happens to be closer to what CSRD's double materiality requirement actually asks for: understanding impact materiality and financial materiality as related but distinct lenses, not a single averaged score.
In our own double materiality tool, we build this in directly — assigning adjustable weights to seven stakeholder groups, then letting a business see how the resulting matrix shifts when regulator concerns are weighted more heavily than, say, media sentiment. The exercise usually surfaces one or two topics that were quietly under- or over-stated in the unweighted version.
None of this replaces judgment. Weighting is a starting point for a conversation with the board and leadership team about where the real exposure sits, not a substitute for it. But it's a much better starting point than a matrix built on the fiction that every voice in the room carries the same weight.
You can try a stakeholder-weighted matrix yourself with our Double Materiality Assessment tool, or contact us if you'd like to commission a full materiality assessment for your business.
