CO2e emissions from transport

CO_2e emissions from transport on a per tonne basis fell slightly during the year. There was an increase in the cement business line due to some operating difficulties that required material to be transported further but this was offset by better vehicle scheduling in asphalt, aggregates and concrete. We now have a higher percentage of our own vehicles meaning we can track fuel use more accurately and provide fuel efficiency training for all our drivers. Rail deliveries increased slightly for aggregates but cement was static.

A project to optimise order handling and vehicle scheduling in the aggregates, asphalt and concrete business lines is ongoing. The aim is to improve vehicle use and reduce fuel costs. The project is focused on the effective and efficient use of our delivery fleet through the introduction of vehicle optimisation software, GPS and a material resource planner (MRP) to schedule internal deliveries.
