Applicable rules first
Flag, port, protected-area and local environmental rules take priority over generic statements.
Operational efficiency
Maintenance, routing, speed, energy management and shore-power use where available can influence fuel and emissions.
Marine protection
Anchoring, discharge, waste and wildlife interactions should reflect local protections and competent marine practice.
Supplier expectations
Partners should comply with applicable law, act responsibly and avoid misleading environmental claims.
Evidence before claims
Environmental statements should be specific, supportable and proportionate to the action actually taken.
