 The LIB urges #COP30 to put biodiversity at the core of climate policy. Without healthy ecosystems, there are no nature-based solutions. „Climate and species protection are two sides of the same coin.”

Our appeal to COP30:
Integrate biodiversity into national climate plans.
Strengthen research and monitoring.
Base decisions on scientific evidence.
