Driving sustainability in our facilities The comprehensive sustainability strategy for our real estate portfolio includes increasing the energy efficiency of our buildings, converting to renewable energy for our internal operations, reducing and/or eliminating underutilized space, and ensuring sustainability in the way we operate these facilities. To achieve and maintain our Scope 1 and 2 GHG reductions, we have invested US$45 million between fiscal 2018 and fiscal 2022 to implement hundreds of efficiency projects such as improving airflow in our labs, installing LED lighting, and optimizing our mechanical equipment. We are in the process of finalizing our investment plans through fiscal 2025 to meet our new net zero Scope 1 and 2 goal. Investments in renewable energy over the past 15 years have helped us drive down our Scope 1 and 2 emissions. Our strategy includes a combination of renewable energy purchases, onsite solar installations, green power contracts with local utilities, and power purchase agreements (PPAs) that add new renewable energy to the local electricity grid, such as our wind PPA in Texas. In fiscal 2021, we sourced 1.3 million MWh of renewable energy, including 100 percent of the electricity used at Cisco facilities in the United States, Canada, and several European countries. We sourced 200 GWh of solar renewable energy certificates (RECs) generated in North Carolina and continued to participate in Duke Energy’s Green Rider program to increase the amount of local renewable energy we procure for our Research Triangle Park campus. We continued to expand our renewable electricity purchases in India in fiscal 2021 by entering into new long-term and short-term PPAs in the country. These agreements bring our total electricity sourced from renewables in India to 66 percent, from 2 percent in fiscal 2015. We also continue to engage with green power providers and buyers to accelerate the use of renewable energy through the Clean Energy Buyers Association (CEBA) 1 and the EPA’s Green Power Partnership . Embracing hybrid work Cisco’s hybrid work model and our collaboration tools reduce the need for business travel and commuting and the resulting emissions. While about half of our employees were in the office four to five days a week pre-pandemic, less than a quarter want to be in an office three or more days a week when offices reopen. In much the same way that work has fundamentally changed, the purpose of our physical space must change too. Therefore, we are transforming our offices to be centers of collaboration—places where people can come together for collective work and connection. In the hybrid world, we’ll best use our offices by transforming them into spaces optimized for teams to innovate, collaborate, and connect. As a part of our hybrid work strategy, we will continue to expand the number of green-certified buildings in our portfolio and embed green building principles into our standard workplace design and daily operations. Our first LEED-certified building was built in 2009. By the end of fiscal 2021, 32 Cisco facilities were certified by LEED, CASBEE, BREEAM, or by another comparable green building certification, and seven were in progress. The fully certified facilities represent 3.7 million square feet of LEED- certified space, which is about 20 percent of Cisco’s global real estate portfolio. We have over 35 locations around the world with onsite electric vehicle charging stations that support GHG reductions in commuting and business travel emissions. We are also continuing to electrify our car fleet in Europe and expect it to be fully electric by 2030. At the end of the fiscal year, 25 percent of our fleet was electric. To reduce our Scope 1 and 2 GHG emissions, we’ve completed hundreds of energy efficiency and renewable energy projects over the past five fiscal years. 360 projects 118 GWh of energy avoided 52,250 metric tonnes of CO2e avoided In fiscal 2021 24 projects 6.6 GWh of energy avoided 2700 metric tonnes of CO2e avoided 1.
