Companies that decide to make wide-ranging energy-efficiency changes are more likely to save money than competitors who choose to do little or nothing, according to a green business expert.Despite the possibility of an initial financial outlay, businesses that choose to embed green-minded measures in their company planning have an increased chance of reaping financial benefits than those making limited changes, claimed Dr Martin Gibson, programme director at Envirowise.He identified transport as an area that firms are increasingly considering when looking to make environmental savings, with the IT sector in particular seeing an increasing level of awareness of the importance of green issues.Dr Gibson explained, "With an overarching strategy - and employees appointed as champions to deliver on the strategy and all the workforce aware of it - then any goal is achievable," Dr Gibson stated."And yes, transport efficiency is going to be increasingly important for businesses, and the IT and computing worlds are waking up to their environmental impacts."Figures provided by the Carbon Trust indicate that if a business reduces its energy usage by 20 per cent it can make cash savings equivalent to a five per cent increase in sales.
