Yahoo recently announced a plan to become carbon-neutral by the end of this year by making its own processes more efficient and contributing to reductions in carbon emissions around the world.Carbon neutrality can be achieved by purchasing carbon offsets, in which a company pays a separate company to reduce its greenhouse gas emissions, instead of reducing its own.
While Yahoo does buy carbon offsets, the search engine company does not intend to count those offsets toward its carbon-neutrality goal, says KC Mares, director of Yahoo data center strategy.Instead, Yahoo is completing projects on its own, such as one to replace stove cooktops in impoverished areas of the world with energy-efficient models.
Yahoo has made its own operations more efficient in a number of ways. The company builds its own data centers and has third parties build Yahoo computers to its own specifications. “We essentially control the entire footprint, so we can make it very efficient,” Mares says. Yahoo uses virtualization to improve efficiency, asks suppliers to deliver everything in reusable packaging, and places data centers where ambient air is cool, lessening the need for air conditioning, he says.
Data centers don’t need to be kept at 70 degrees Fahrenheit anyway, as many are, he says. They can survive just fine at 85 degrees, he says. Yahoo doesn’t use air conditioning to cool data centers for two-thirds of each year.Yahoo’s green computing goals were driven mostly by users, who are increasingly looking for information on how to help the environment on the Yahoo Web site.“We’re driven mostly by customer demand,” Mares says.
