Cisco has come up with a number of solutions to cut down on emissions from transportation and commuting. Cisco Virtual Office offers full IP phone, wireless, data, and video services, providing more than 16,000 employees the opportunity to work from anywhere. This translates to roughly 19,000 metric tons of CO₂ saved every year. Additionally, Cisco TelePresence offers high-quality sound and video for virtual conferences, which helps curtail emissions from energy use. In 2009, Cisco purchased 37 percent of its electricity globally from renewable energy sources.
