Keith L. Kline, ORNL

Keith L Kline

Distinguished Scientist, Environmental Sciences & Climate Change Science Institute

Keith was raised on the family farm in Michigan and earned a BSc from University of Michigan School of Natural Resources in Ann Arbor, and a Masters from Framingham State University, International Education. Keith's current work focuses best practices for a resilient bioeconomy and international standards to support rural development. Keith's professional career began with projects that involved renewable energy systems, sustainable agriculture and forest management. Current research aims to apply scientific approaches and causal analysis to reduce regulatory barriers associated with faulty modeling assumptions and improve understanding of drivers of change in land cover. This work identifies innovations to promote beneficial “land-use change” (improved management of natural resources and implementation of nature-based solutions); integrated agro-silvo-pastoral and urban production systems; and practical approaches to support adaptive management and continual improvement. Keith contributes to voluntary international standards initiatives addressing global barriers to a resilient and sustainable bio-economy including verifiable and practical approaches for carbon accounting and common-sense approaches to monitoring and evaluation. Keith was honored to be elected Fellow of the American Association for the Advancement of Science (AAAS) in 2024. Current research supports the Biofuture Project; standards for measuring performance of a resilient and circular economy; the the reduction of uncertainties in land-system modeling.
