New technology is making it possible to see shipping emissions in far greater detail than before. A system called EMMA, developed by Ocean OS, uses artificial intelligence alongside data from satellites and local sensors to track where emissions from ships come from and how they move through air and water.

After six months of testing in Plymouth Sound, the system has now been launched more widely. It brings together information that was previously scattered, allowing ports, regulators and other authorities to build a clearer picture of how maritime activity affects local air and water quality. This includes showing how pollutants build up in specific areas and how they travel once released.

The aim is practical decision-making. By understanding when and where emissions are having an impact, organisations can take targeted action to reduce pollution where it is within their control. Just as importantly, the data can also show when pollution is coming from elsewhere, helping to ensure responsibility is shared fairly.

The project is a collaboration between technology companies, academic partners and satellite specialists, with public funding support. The intention is to expand monitoring around more of the UK coastline, with the ambition that the system could support cleaner, lower‑carbon operations in major ports.

For Devon, and other coastal areas, approaches like this show how innovation can support the journey to net zero. Better data helps protect health, improve environmental standards and guide investment in cleaner transport and infrastructure without relying on guesswork.
