Decarbonising Maritime Shipping: Regulatory Landscape
March 2026
Maritime shipping accounts for approximately 3% of total global greenhouse gas emissions and at the current rate, could increase to 10% by 2050. Governments and regulators worldwide are implementing regulatory frameworks to help decarbonise the sector. This report explains the changing regulatory landscape across the IMO, EU, and UK, focusing on three main areas: optimising emissions and energy efficiency, providing infrastructure and enforcing compliance, and influencing digital solutions. The report helps maritime stakeholders to navigate the increasingly complex regulatory environment and its implications. It concludes that operators that proactively adopt compliance measures, engage with digital solutions, and invest in energy efficiency technologies can position themselves to thrive in the zero-carbon maritime sector of the future.
