ACCOUNTABILITY REPORT ENVIRONMENTAL AND SOCIAL RESPONSIBILITY 2021 Managing our direct environmental impact

Natixis’ business travel policy has set out rules ensuring the safety and comfort of employees during business trips, while contributing to the policy of optimizing costs and managing the environmental impact of these trips. This policy applies to Natixis and its subsidiaries, excluding Financial investments in France. The subsidiaries and branches abroad establish travel rules that are consistent with the Group’s Worldwide Travel policy. This notably includes rules on business travel that has an environmental impact: when a destination can be reached by both rail and air, trains are V now compulsory for a number of destinations in France and Europe (depending on journey time); economy class is compulsory for domestic flights, flights between V European countries and intercontinental flights of less than four hours; the use of taxis and the reimbursement of mileage expenses are V governed by rules on specific use (approval by manager, exceptionalcircumstances).Natixis also prefers that its employees use green taxis (hybrid vehicles) for business travel. Management of resources 7.4.4 The Workplace Department managing Natixis’ Real Estate ensures optimum resource management by closely managing the various resources used: energy (electricity, heating and cooling utilities), water and paper . Each building it manages has a budget for energy consumption, which is monitored on a monthly basis.

In France, Natixis has optimized the energy consumption of its buildings for several years with the roll-out of variousmeasures: the Technical Building Management system (BMS) to closely V monitor the use of lighting, heating, cooling and air (automatic switching off of lights and air conditioning, optimizationof heating and cooling consumption with better consideration of the outside temperature); a re - lamping policy with the use of LED light bulbs; V installation of motion sensor lighting systems in common areas. V In addition, on eight pilot sites, in order to better monitor the electricity consumption of buildings, the Smart Impulse solution coupled with sensors makes it possible to distinguish the different consumptions related to IT, lighting, ventilation, and heating and cooling if produced by electricity. This monitoring makes it possible to highlight any deviations, and on this basis, the implementationof corrective actions. In addition, the implementation of cleaning during the day was systematized in buildings to reduce the extent of use of the building and therefore its energy consumption. This environmental gain is accompanied by a societal gain for the employees of Natixis service providers, benefiting from a better quality of life through daytime working hours. These different measures combined with awareness-raising and employee engagement via a guide to green actions , challenges and conferences make it possible to observe a downward trend in the energy consumption of buildings since 2010. In addition, as part of the profit-sharing agreement, Natixis and its subsidiaries in France offer a bonus to each employee if the objective of reducing energy consumption is collectively achieved. The specific situation related to COVID-19 in 2020 and 2021 directly impacted the energy consumption of buildings: an increase in consumption : the legal obligation to constantly V renew the air in air-conditioned buildings leads to the permanent operation of air renewal systems that were previously only triggered on an ad hoc basis. In addition, the continuous injection of outdoor air requires that the heating or air conditioningsystems be operated to regulate the temperatures; a reduction in consumption : as employees have benefited greatly V from remote working, the real estate portfolio has been rationalized (closure of certain buildings, adapted configuration of the remaining buildings), resulting in a reduction in the energy consumption of Natixis buildings. It should be noted that this decrease is qualified by the transfer of energy consumption to the homes of employees, which Natixis is unable to assess.

Energy: less and better

7.4.4.1

Reduction of energy consumption The reduction in energy consumptionof Natixis buildings has been a trend observed for more than 10 years. In 2015, Natixis signed a Paris Climate Action partnership with the City of Paris with an objective of a 30% reduction in the energy consumption of its buildings in the Paris region between 2010 and 2020. At the end of 2020, the decrease was 47%. The reduction in energy consumption must now continue, particularly as part of the building master plan. It is now included in the Natixis strategic plan with the aim of -40% between 2019 and 2024.
