The 21st GreenPort Congress will take place at Portsmouth International Port 7-9 October 2026, reinforcing the Solent’s position at the forefront of sustainable maritime innovation and environmental leadership in the port sector.
Organised by Mercator, GreenPort Congress is an annual conference and networking event for the global port community. The conference focuses on sustainable environmental practices, decarbonisation, and reducing the carbon footprint of port operations. It brings together decision-makers, environmental managers, and industry leaders to discuss the latest developments in sustainable port and terminal operations.
The selection of Portsmouth International Port as host port and venue reflects its growing reputation as a leading example of environmental ambition in action. Owned by the people of Portsmouth, the port is actively reshaping its operations to reduce emissions and accelerate the transition to cleaner maritime activity.
With bold plans to become one of the UK’s first zero emission ports by 2050 and to achieve net zero port operations by 2035, Portsmouth International Port is positioning itself as a “living laboratory” for new technologies and sustainable solutions. These ambitions are closely aligned with both Portsmouth City Council’s climate change strategy and the UK Government’s Maritime 2050 vision, ensuring local action contributes to national and international decarbonisation goals.
The port is also committed to collaborative environmental progress, having signed the Portsmouth Green Partnership Charter, reinforcing its role as an active partner in driving air quality improvements and reducing the city’s overall carbon footprint.
Portsmouth is looking forward to hosting this year’s GreenPort Congress, an important event in the industry calendar. We pride ourselves on being a leader in sustainable and innovative maritime operations, and take our role as a city-owned port seriously by making sure we work with the community and customers who share our values. The event in October will take place in our carbon neutral terminal, one of the UK’s most sustainably advanced buildings, and delegates will be given an insight into the green technologies we have here at the port.
Mike Sellers Director at Portsmouth International PortAs the sector faces increasing pressure to decarbonise while maintaining operational efficiency and global competitiveness, the 21st GreenPort Congress will provide a timely platform to share best practice, explore emerging technologies, and accelerate practical solutions for a more sustainable maritime future.
