Better for business, and for the
ISM transports almost 5,000 tonnes of materials and goods by river and sea each day, keeping around 250 lorry journeys off the South East’s busy highway network. That typically saves up to 90% of the carbon and particulate emissions of the equivalent road haulage.
Marine transport is also a safe, reliable and cost-effective transport option.
