Dell is claiming that its the first major computer manufacturer to commit to neutralising the carbon impact of its worldwide operations in a "significant extension of its global climate policy and environmental stewardship".

"Never before in the history of business have we seen such a critical need to build a worldwide community dedicated to improving the environment", Michael Dell, the company's chairman and CEO said.

"Leadership starts at home, which is why we are going carbon-neutral, but this should only be the beginning of building long-term partnerships with customers, stakeholders and suppliers of all sizes to team up and make a difference for the Earth we all share", Dell said.

Dell also issued a challenge to its rivals to join in "a long-term, carbon-neutral commitment to our shared Earth".
