Drivers whose vehicles have been idling for long periods can now be sent a text message to their phones alerting them to the opportunity to conserve fuel.

This is one of a range of tools available to fleet managers using sophisticated tracking and telematics to manage their vehicles.

System developers are building environmental reporting tools that allow managers and drivers to be much more proactive and find ways to reduce fuel consumption and emissions.

One tracking company, Masternaut, has launched an environmental initiative which it calls GreenerFleet.

It pulls together a range of Masternaut developments, such as satellite navigation and real-time tracking, and provides a measurement and management system designed to reduce carbon emissions.

Reports will display the performance of vehicles, drivers and routes, helping managers to identify poor driving practices, unnecessary mileage and excessive idling.

A live ‘carbon calculator’ links accurate vehicle mileage to the vehicle’s CO2 emissions.

GreenerFleet will be able to provide monthly, weekly and daily carbon footprint figures for each vehicle and driver.

Martin Port, managing director of Masternaut, said: “We are committed to innovation to meet the ever-changing needs of customers and we have had interest from existing customers who have pledged to reduce their carbon footprint. We all need to do our bit and our new tools give industry an easy-to-implement solutions that will enable real reductions in CO2.”

Whether or not drivers will appreciate being told to “turn it off” by text, remains to be seen and unless it is handled sensitively, drivers might hit back at Big Brother-style intervention.
