Dell says it has enforced its commitment to being an energy efficient and carbon neutral company by joining The Climate Group. Dell is the first computer company to have joined the global non-profit organisation.

The computer manufacturer has already lowered its carbon intensity (its ratio of carbon emissions to economic activity), but has pledged to reduce this by a further 15 percent by 2012. It has also pledged to make its manufacturing operations and company facilities carbon neutral beginning this year.

"The Climate Group is delighted to welcome Dell as our first IT member. Dell revolutionised the PC business, and we believe it can do similarly great things for the IT industry's efforts to reduce greenhouse gas emissions. Dell's extensive product reach into homes and offices creates the potential to make an even greater contribution to creating a low-carbon economy," said Chris Walker, director of The Climate Group.

The Climate Group works with business and government leaders to address climate change and accelerate the transition to a low-carbon economy.
