More than half of Yorkshire's businesses are still oblivious to a new 'green' energy tax.

In a regional survey by Yorkshire Electricity, more than half of those asked knew nothing about the Climate Change Levy, which will be introduced this April.

Part of the Govern-ment's environmental strategy to reduce the UK's carbon dioxide emissions, YE thinks the levy could increase commercial energy costs by up to 15 per cent.

The company, like Bradford's Chamber of Commerce & Industry, is offering firms a range of energy efficiency tips to help cope with the new cost.
