CO2e emissions from transport
CO2 emissions from transport on a per tonne basis rose by one per cent during the year. This was principally due to an increase in delivery distances for aggregates and asphalt. We are looking at new metrics for monitoring the carbon and energy efficiency of our delivery fleet as the traditional measure such as fuel consumption and CO2 per tonne delivered can mask improvements in performance as a result of increased activity.
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 both aggregates and cement.
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.
