Businesses can help to reduce their carbon footprint through the use of IT, it has been suggested.John Buckley, managing director of environmental advice group Carbon Footprint, said companies could cut emissions by allowing employees to work offsite and by holding meetings via video conferencing - which could lead to a significant reduction in transport emissions."IT is a great enabler to help reduce carbon emissions and at the same time can reduce costs for the company in reductions in travel expenses and staff travel time," he commented.Mr Buckley added that in order to reduce emissions further employers must train staff to use standby modes and turn electrical equipment off when not in use."Computer servers are a significant source of energy wastage as well. Most servers are significantly under-utilised and over-specified for the jobs they do," he continued.According to a report by Zero Carbon Footprint, the average PC emits around 220kg of CO2 annually.
