About
Scale provides strategic guidance and technical support to help clients set and achieve ambitious goals for climate action and natural resource stewardship. We believe that natural and working lands must be central to both fighting and adapting to climate change: they hold the key to generating the negative emissions humanity needs to get to net zero, and are essential to the longterm health and wellbeing of every species on the planet. Forests, grasslands, agricultural lands, and whole ecosystems are the only climate tech that provides food, water, shelter, and spiritual sustenance.

Claire Jahns is Founder and Principal of Scale. Scale grew out of Claire's independent consultancy, which she started in 2018. Recent clients include the U.S. Climate Alliance and its member states, Rhodium Group, and the Marin Agricultural Land Trust.
Claire served as Assistant Secretary for Climate Issues at the California Natural Resources Agency under Governor Edmund G. Brown. In this role, she led development of California’s Natural and Working Lands Strategy and adoption of California’s first quantitative goals for GHG reductions derived from natural climate solutions. Prior to this, Claire served as a project director at The Nature Conservancy, where she worked with landowners, public officials, and other partners to develop solutions at the intersection of agriculture and biodiversity conservation in California and the American West. Claire was an economist at the Chicago Climate Exchange from the Exchange’s opening in 2003 to 2007, and contributed to the world’s first exchange-based carbon credit and offset transactions.
Claire holds a Masters of Environmental Management from the Yale School of Forestry & Environmental Studies, an MBA from the Yale School of Management, and a BA from Oberlin College.
