Global Citizenship Report 2017

Transparent Reporting of Operational Climate Impacts Citi reports our Scope 1, Scope 2 and Scope 3 GHG emissions in both our annual Global Citizenship Report and in our CDP response. We began reporting on the direct environmental impacts of our operations in 2002 and have submitted data to CDP every year since 2003. We follow the GHG Protocol Corporate Standard and Scope 2 Guidance for measuring and reporting both market-based and location-based Scope 1 and Scope 2 GHG emissions. We also report Scope 3 CO 2 emissions from employee air and train travel and project- financed thermal power plants in our Citizenship Report, and Scope 3 electricity transmission loss and employee commut- ing data to CDP. In 2017, Citi received a score of A- on our climate change impact reporting for 2016 data. Disclosure of Scope 1, Scope 2 and Scope 3 GHG emissions is also a component of the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD), under metrics and targets. As we continue to assess climate-related risks and opportunities, we will also determine whether additional targets and metrics are needed, beyond those we currently report, to manage, measure and track our performance.

Sustainable Building Principles at Work The renovation of our global headquarters in New York, for which we plan to seek LEED Platinum certification, is on track to be complete by 2020. With this renovation, we are improv- ing indoor air quality by installing direct outside air systems, which balance recirculated air with outside air. We are also using low-emitting adhesives, sealants, paints, coatings, floor- ing and composite woods. Water-conserving plumbing fixtures could save up to 100,000 gallons of drinking water each day, and our cogeneration plant, fueled by natural gas, will produce heat and electricity on-site, reducing the building’s carbon footprint by 30 percent — a key contributor to our commitment to meeting the NYC Carbon Challenge. Outside the building, we preserved the mature trees lining Greenwich Street and planted new ones. We also put in more than 8,500 square feet of new plantings and a 3,500-square-foot lawn. When the project is complete, we will recapture approximately 2 million gallons of water annually from the building’s roof and reuse more than 80,000 gallons to maintain the plantings in the plaza. Nearly all the demolition waste from the project is being recovered, reused or recycled. The way we procure energy for our buildings is another import- ant consideration for our environmental footprint. In 2016, we established a contract to purchase energy for our data center in Roanoke, Texas, through a collaboration between Citi Realty Services (CRS) and our subsidiary, Citi Energy Inc. (CEI). The Texas data center marks the first collaboration between the two groups. Through this project, Citi will use green e-certified renewable energy for 100 percent of the data center’s electricity usage and has worked with a retail electricity provider to arrive at a pricing structure that provides renewable power at an attractive price point. The CRS and CEI teams are proactively identifying additional projects to partner on to help us meet our renewable energy needs and energy reduction goals. 64
