The Digital Euro and energy considerations: Can the ECB introduce the Digital Euro considering the potential energy requirements?

The ECB has two mandates its primary and secondary mandate. Its primary mandate has been the focus of many discussions but its secondary mandate is less frequently discussed. Nevertheless this mandate has important objectives and should not be considered obsolete. This article examines the legal status of the secondary mandate of the ECB with regard to climate change. In particular this article will consider the role of the secondary mandate with regard to the Digital Euro and energy targets. The Digital Euro can be used as a monetary tool and improve payment systems. However, depending on its design the Digital Euro can use a considerable amount of energy. This article concludes that if the design of the Digital Euro does not impact the monetary objectives, the secondary mandate of the ECB determines the design of the Digital Euro.
