Customer solutions For more than 30 years, Cisco has been helping businesses, communities, and countries transition to a digital economy. More recently, we have been helping them adapt to a low-carbon economy, as well. Our industry has an important role to play. For example, a lifecycle analysis focused on the Webex Desk Pro found that avoiding 24 commute trips per year in the San Francisco area by using the device at home could offset the entire lifecycle greenhouse gas emissions associated with the Desk Pro. Our technology can also be used to help the world prepare for the outcomes of a changing climate—such as to monitor grid reliability, enable grid decarbonization, monitor transportation and water systems, and support the workplace of the future. For example, through Webex by Cisco, AnyConnect VPN, and TelePresence, Cisco is providing the tools that make it possible for millions of employees to work from home daily. These technologies also reduce GHG emissions associated with commuting and other business travel. Enabling smart buildings for the future of work Cisco’s Smart Building solutions can help our customers reduce their energy use through low-voltage Power over Ethernet (PoE) smart switches that provide network- based monitoring and control of temperature, lighting, air quality, and other building characteristics. Using these solutions, facilities operators can monitor systems and devices, manage energy use, track occupancy levels to protect occupants’ health and safety, and troubleshoot issues. As an example, when ASHRAE , the world’s leading building standards organization, moved to a new corporate headquarters, it partnered with Cisco and NTT to retrofit a 43-year-old building into a secure, innovative, and sustainable workspace. The building’s universal PoE foundation, powered by Cisco, allows all systems to be managed over the network through an integrated building management system. ASHRAE’s new building uses this technology to securely enable an intelligent reception system, space-specific HVAC optimization program based on occupancy, and an energy management system combined with an onsite solar energy system that enables the building to consume less power than it generates. A smarter power grid for Enel As Italy’s largest electricity provider, Enel needs to make sure that its services are reliable. We’ve partnered with Enel to help keep the lights on by creating a smarter, more efficient power grid. Enel is working with Cisco to introduce innovative solutions for agile grid operation, regulation, and supervision. Using Cisco technology, Enel can monitor its energy grid and preemptively address any faults or failures that threaten the network. Cisco is also helping Enel connect its grid to renewable energy sources like solar and wind energy at scale, speeding the transition to a low-carbon electricity grid. Together, Cisco and Enel are making energy more reliable, more affordable, and more sustainable. FUTURE INTRO POWER INCLUSIVE 2021 Cisco Purpose Report | csr.cisco.com | ESG Reporting Hub 81
