Tanja runs Duke University’s biogas strategy, where she focuses on RNG market creation. Duke has prioritized biogas since committing to climate neutrality in 2007.
Tanja’s first efforts on biogas at Duke began at the University’s Carbon Offsets Initiative, where a key priority was to test the viability of swine waste-to-energy systems capable of meeting stringent environmental standards while generating offsets and renewable energy. Tanja leveraged private and public funding to build the Loyd Ray Farms (“LRF”) system, a partnership with Duke Energy, the Loyd Ray Farms and Google. Results from the project were then used to identify least-cost approaches for meeting NC’s REPS swine mandate and create a roadmap for scaling biogas development. Companies like Smithfield Foods and Dominion Energy are using concepts established by Duke to guide current biogas development commitments.
Beyond biogas, Tanja has investigated other offset types and teaches on topics including climate change mitigation, clean energy access and energy equity. Her current policy activities include helping the state’s natural and working lands initiative identify mechanisms to fund resiliency and carbon mitigation measures on agricultural operations. Tanja also co-leads an analysis to determine NC’s biomethane production potential from all organic waste sources.
Tanja graduated from Yale University with degrees in Geology & Geophysics and Studies in the Environment and holds a J.D. from The George Washington University Law School.
