On its website Natixis states: 'aware of  its social and environmental responsibility, Natixis has a sustainable development policy aiming at reducing its impact on the environment and being part of corporate social progress and open to civil society. This policy concerns both our businesses and our day-to-day behavior, with a growing commitment of Natixis' employees.' This policy is not publicly available on its website though.

In March 2009, as part of the responsible management of its activities and their consequences, Natixis adopted a policy to exclude all financing and investment in companies involved in the manufacturing, storage and trade of land mines and cluster bombs. This policy applies to the financing of these companies, to proprietary investment, to third-party asset management by Natixis Asset Management, which has also launched a customer awareness approach.
