This report defines and assesses options to establish an EU-wide green label with a view to promote the use of renewable energy coming from new installations as required by Art. 19 (13) of the Renewable Energy Directive recast (EU) 2018/2001 (RED II). The RED II highlights the role of consumers in transforming the energy system by purchasing green energy products. In order to do this, consumers must be provided with the necessary knowledge about green energy products and their features. Green energy labels are one of the tools that can provide easy to understand information to consumers regarding the sustainability of their energy and the contribution that their energy purchase makes to the transition to a zero-emission energy system.
