WELL Building Health-Safety Rating In 2021, as a result of our health and safety practices, we received the International WELL Building Health-Safety Rating for all Citi facilities globally, including offices, operations centers, data centers and retail locations. This seal helps assure our employees and customers that our buildings are safe and healthy environments. The seal is awarded to businesses that meet rigorous scientific standards, maintenance protocols and emergency plans to address concerns related to COVID-19 and other infectious diseases now and into the future. WELL Portfolio Program Building on the success of the WELL Health-Safety Rating, Citi joined the WELL Portfolio Program — a benchmarking program for measuring and improving organizational health performance across facilities. The WELL Portfolio Program leverages the strategies of the WELL building standard, the leading health-focused building standard. As a participating organization, Citi will receive an annual portfolio score based on our work to support and enhance the health and well-being of employees and customers who work in and visit our buildings every day. consumption by 15.7%. We also reused 77% of the facility’s furniture to reduce waste, and we were able to effectively manage c onstruction-related w aste, capping the volume sent to landfill at 31.7 kg/m 2 , which is 15% below the industry standard. • Paraguay (EDGE Advanced): We earned our first EDGE Advanced Certification for our Agrovet Offices in Paraguay. The Excellence in Design for Greater Efficiencies (EDGE) certi - fication system evaluates buildings in three resource categories: energy, water and materials. We earned Advanced Certification through the use of features that increase energy efficiency by 63% (mainly related to the building’s heating and cooling systems), increase water efficiency by 20% through high-efficiency accesso - ries in restrooms and reduce embodied energy of materials used for interior spaces by 89%. • China, Taiwan, United States (LEED Volume Program): We accomplished LEED v2009 certification for 11 bank branches through the LEED Volume Program and achieved LEED v4 Gold for our fourth retail prototype. All new and renovated bank branches will be LEED Certified based on this model. We are also planning a significant renova - tion of Citi Tower in London, headquarters for our Europe, Middle East and Africa region. For this project, which we expect to complete in 2025, we are prioritizing sustainable building principles and employee well-being in alignment with LEED, BREEAM and WELL standards. By renovating the existing building, rather than demolishing it to build a new struc - ture, we will avoid releasing an estimated 100,000 metric tons of embodied carbon, equivalent to 21,748 passenger vehicles driven for one year. 3 We are designing Citi Tower London for energy efficiency from top to bottom, within the constraints of an existing building, and are factoring carbon emissions into our decision-making process. The building will feature rooftop solar panels generating more than 52,000 kilowatt-hours per year annually — enough to power 18 average UK homes 4 for one year.
