Leipzig has been participating in the international certification system "European Energy Award" (EEA) since 2009. The annual implementation report in a handy brochure format provides information on the progress of this complex municipal climate protection project. It is a central element of citizen communication and is therefore designed to be inviting, clear and understandable: Instead of complicated technical terms and long texts, we opted for playful, bright covers, clear structure, airy layout, short texts without numbers, infographics and illustrations.
