Intel CEO Paul Otellini joined a call on Thursday for Group of Twenty (G20) finance ministers and central bank governors to implement policies that encourage investment in environmentally friendly technologies and agree on a more effective climate treaty.
He was the only head of a major high-technology to sign the letter drafted by the Copenhagen Climate Council.
Otellini and the other signers of the letter, which include business leaders, academics and scientists, are members of the Copenhagen Climate Council. The group was created to build awareness for the UN Climate Change Conference, scheduled to be held in Copenhagen in December.
"We believe that this year we are at an historic crossroads. Either we establish a new more effective global climate treaty to tackle the climate problem, or we jeopardise our common future," the group wrote in the letter, which was also published in the International Herald Tribune newspaper.
"Either decision-makers lay the foundation for sustainable, economic recovery - or we will hand huge risks to our children," the Copenhagen Climate Council said.
