Exclusions vs engagement: different tools, different governance needs

Exclusions define boundaries. Engagement defines a monitored process. Both can be credible, but they require different controls and evidence.

The distinction

Exclusions Binary control: “do not own”. Credibility comes from clear scope and consistent enforcement.
Engagement Time‑bound process: “own, monitor, influence, escalate”. Credibility comes from objectives, traceability, and escalation discipline.

Exclusions as controls

Exclusions are easiest to audit. A third party should be able to verify that holdings comply with the stated boundaries.

Engagement as a process

Engagement is harder to evidence because it involves time and judgement. Credibility requires a structured approach: objectives, timeline, and escalation.

Objective Specific and measurable enough to evaluate progress (not a broad sustainability promise).
Timeline A defined horizon; engagement without time is indistinguishable from inaction.
Escalation What happens if progress is insufficient: voting, restrictions, or exit—documented.

What evidence looks like

For professional review, evidence is not tone. It is traceable artefacts:

Exclusions

Holdings alignment

Rules mapped to holdings, with clear thresholds and consistent application.

Engagement

Recorded process

Objectives, interactions, progress checks, and escalation decisions recorded over time.

Common pitfalls

  • Engagement described as a substitute for exclusions without clear escalation.
  • Exclusions communicated broadly but defined narrowly or with unclear thresholds.
  • Language that implies outcomes (“impact”) without a reporting structure that can evidence them.
