Greener pensions, greener choices : linking investments to sustainable behavior

This paper examines how offering sustainable investment options influences sustainable consumption behavior. We combine a natural experiment in which individuals receive an option to switch to a pension plan with a strong sustainability profile with detailed household register data. This sustainable option improves sustainable consumption, as reflected in electric vehicle adoption and reduced vehicle emissions. The effect is primarily driven by individuals who do not choose the sustainable plan. We show that making sustainable investment available can create positive spillover effects on other sustainable behaviors, highlighting the potential of financial tools to support broader societal change.
