The information technology industry accounts for about 2 per cent of global carbon dioxide emissions – about the same as the airline industry. Although the technology is increasingly power-efficient, more innovation and design are required to offset the growing use of computers, especially in China and India.
“The focus on innovation has led to a host of developments, through green ideas and exotic new equipment,” says Sumir Karayi, chief executive of 1E, a power management software vendor that claims to have cumulatively saved its customers 4m metric tonnes of carbon dioxide emissions.
