As a leader, my guard against greenwashing is this: prioritize the authentic transformation over the appealing narrative.
That means:
Measure what hurts: Set ambitious, science-based targets for your biggest impacts, not your easiest wins.
Integrate, don't delegate: Make sustainability a core KPI for every department head, not just a side project for a separate team.
Lead with progress, not perfection: Communicate your journey transparently—share baselines, shortfalls, and course corrections, not just final victories.
Welcome scrutiny: Engage sincerely with critical voices; they reveal the blind spots your internal reports won't.
