Green port programme

A green port programme is a structured scheme by which a port measures, reports, and reduces its environmental footprint and rewards cleaner ships. The European benchmark is EcoPorts, run by ESPO, whose Self-Diagnosis Method and PERS certification track air quality, waste, water, and energy. On the ship side, the Environmental Ship Index (ESI), administered through IAPH and used by over 60 incentive providers, scores a vessel’s NOx, SOx, and CO2 performance and shore-power readiness, letting ports grant discounted dues to high-scoring ships. Together they form the incentive layer of a port’s energy-transition and sustainability strategy.
