Where feasible, we have estimated the impacts representative of Citi’s financing and facilitation activities. Our impact measurement methodologies align with our accounting approach, reporting our share of the impacts proportional to our financial share of the transaction. Impact Calculation Methodology Summary Citi initiatives help to create measurable impacts for communities across the world. To estimate the environmental and social impacts of Citi-financed projects and activities we looked at the following metrics: • Avoided GHG emissions refers to the amount of GHG emissions avoided because of Citi’s share of financing for renewable energy, green affordable housing and energy efficiency projects. GHG emissions avoidance is calculated by applying regional electric grid factors to Citi’s share of financing across three types of activities, including a low-carbon source replacing energy use from the grid, energy efficiency upgrades and green housing units that are LEED-certified. Impacts reflect the per annum benefit as opposed to benefit over entire project life. • For renewable energy projects, total project capacity for energy is calculated as the annual capacity factor applied to the total project size per annum and multiplied by the CO 2 emissions factor. • For energy efficiency upgrades, the average household energy savings is calculated as the average household energy use multiplied by the percentage of energy savings per thousand U.S. dollars invested. The result is multiplied by the total warehouse value and the CO 2 emissions factor.
