Ford has instigated an energy-saving programme across its business, saying actions as simple as shutting down computers at night and weekends can make huge savings.
It estimates that 60 per cent of its employees globally don't shutdown their computers at the end of a working day. Doing do, it says, would save 16,000-25,000 metric tonnes of carbon dioxide a year and $1.2m (£800,000) in energy costs.
As a result, Ford is installing a new programme on its computers to maximise power saving potential. This will include a managed shutdown of all computers each night and weekend.
