The demand for investment solutions is changing. Investors are increasingly concerned about directing their savings to companies that behave responsibly, or even directly financing sustainable development projects. The challenge for asset managers is therefore to offer sustainable finance solutions, which are developed with a long-term vision of the impacts of the underlying investments, capable of combining a return and providing measures of impact. Asset managers owe it to their clients to make informed investment decisions that carefully consider financial, operational and reputational risks. As such, their fiduciary duty expands to consider non-financial impacts (impacts on the environment and on society) in their search for long-term profit. Corporate practices of asset managers should at least meet or exceed the standards imposed on the invested entities, it is as such mandatory for asset managers to integrate sustainability into their own operations and to be transparent about targets and progresses made.
