Deutsche Bank Transition toward a sustainable and climate-neutral economy Non-Financial Report 2022 In-house ecology Water Water is an increasingly scarce resource in many countries worldwide, and Deutsche Bank takes a variety of steps to conserve water. For example, in 2022 Deutsche Bank installed sensors in new offices to detect leaks and automatically cut off the water flow. For example, water flow is stopped when floors are not occupied, which prevents waste, such as when a tap is accidentally left running. Low-flow aeration faucets and water-efficient products are installed whenever new services are required or facilities are refurbished. Water consumption in 2022 was again lower year-on-year. However, it is increasingly difficult to achieve further significant reductions owing to the success of earlier efforts. As in previous years, Deutsche Bank’s water came exclusively from the municipal water supply or other public or private water utilities. No surface water, ground water, seawater, produced water, or third-party water is used. Water is not recycled or reused.

The previous year is always adjusted to January to December. Average uncertainty is +/- 10% for all KPIs. 2 The reasons for changes to prior-year figures include updates to historical data (such as billing updates) and methodology changes 3 Actual water consumption data is based on meter readings and invoices. Water figures are extrapolated for each building based on occupied area and refer to potable (municipal) water only. 4 All FTE metrics use an annual average from the period October 1, 2021, to September 30, 2022 (83,454) 5 All floor area metrics use an annual average derived from data for the period October 1, 2021, to September 30, 2022 (2.846 million m²) 68
