A 'Robin Hood tax' on all transactions between financial institutions that has been proposed by a coalition of charities, unions and aid agencies could help make homes more energy efficient.
It is anticipated that the tax will raise up to £250 billion a year to help tackle climate change, fight poverty and protect public services.
According to the campaigner's website: "The UK poverty-fighting charities who are supporting the Robin Hood tax have highlighted tackling child poverty, reforming the welfare system, investing in affordable housing and making homes more energy-efficient as the key issues to be tackled."
Oxfam, Barnardo's, The Salvation Army and ActionAid are among the organisations that are calling for support for the levy on financial dealings between banks.
An online campaign has just been launched in the UK starring actor Bill Nighy to try to gather support for the tax, which will see money split between domestic services and international development projects.
By making homes more energy efficient in an effort to tackle climate change, the tax will also help households to save money on their energy bills.
Cutting energy bills is a concern of businesses as well as homes, according to a recent survey carried out by the Carbon Trust.
From the survey of over 700 business people across the UK, energy prices was found to be the greatest worry.
