Daniela Schiffer and Markus Schulz are the minds behind the Klima-Taler app – a climate protection concept born from their decades of experience in environmental communication. Both have long been working at the intersections of climate protection, digitalization, and societal change. Their key insight: knowledge alone is not enough to change behavior – it takes incentives to break away from familiar paths, and partners who help shape new ones. With this understanding and the conviction that change is possible, can even be fun, and that good ideas need to be shared, they support cities, towns, and municipalities in implementing regional climate protection concepts with Klima-Taler.
