Klaus Kümmerer

Prof. Dr. Klaus Kümmerer serves as a faculty member at Leuphana University Lüneburg, Germany, where he leads research at the Institute for Sustainable Chemistry and Environmental Chemistry and the International Sustainable Chemistry Collaboration Centre. His work focuses on establishing sustainable chemistry as a fundamental guiding principle for the chemical sciences.

Kümmerer's research interests center on sustainable chemistry as a holistic framework that transcends traditional chemical subdisciplines. He argues that sustainable chemistry must consider the entire lifecycle of chemical products, from initial design through end-of-life considerations. His work emphasizes the need to move beyond conventional green chemistry approaches by addressing fundamental questions about resource limitations, thermodynamic constraints, and the societal function of chemical products. Kümmerer advocates for designing chemicals with appropriate reactivity and lifetimes specific to their intended use contexts.

His publications reveal a strong focus on the philosophical and practical foundations of sustainable chemistry, examining how chemical science can contribute to broader sustainability challenges while maintaining its scientific integrity. The research demonstrates particular attention to the limitations of current approaches like the Twelve Principles of Green Chemistry and explores how sustainable chemistry can inform circular economy models while acknowledging thermodynamic realities.

Kümmerer actively participates in international discourse on sustainable chemistry, with his work recognized by the United Nations. In May 2016, sustainable chemistry was acknowledged by the UN as one of the most important approaches for sound chemicals management, reflecting the significance of his contributions to the field. His conceptual framework extends beyond technical solutions to include business models like chemical leasing and emphasizes the role of chemists in designing for sustainable disassembly and natural degradation.
