This work is independent, reflects the views of the authors, and has not been commissioned by any business, government, or other institution. The authors of the report confirm that: 1. There are no recommendations and/or any measures and/or trajectories within the report that could be interpreted as standards or as any other form of (suggested) coordination between the participants of the study referred to within the report that would infringe EU competition law; and2.
