The expertise gained on green energy courses could help firms to save money, since one source has suggested there are more than just environmental benefits to certain innovations.

General manager of the Carbon Trust Footprinting Company (CTFC) Euan Murray claimed that the most carbon emissions are often produced in unlikely places and cutting them down can lead to financial savings.

He suggested that professionals who have taken green energy courses will be best placed to work out the optimum way of making operations more environmentally friendly.

Mr Murray said: "If a business wants to reduce either its overall emissions, or the emissions produced through making a specific product, it is important that it works with experts."

In his opinion, the popularity of green improvements is continuing to grow as more and more firms realise the savings that can be made and the impact they can have on the environment.

The CTFC works with businesses and consumers to help with the measurement, certification, reduction and communication regarding greenhouse gases.
