David Ligh

Senior Advisor

David retired from Exxon Mobil Corporation in 2022, completing over three decades of external affairs experience representing global energy companies before government officials and external stakeholders on a full range of priority issues, including energy, ESG, petrochemicals and tax. He established a strong reputation for leveraging his technical background and training with his extensive experience working with policymakers and stakeholders on improving policy proposals and developing new approaches to achieve business objectives.  

David advised senior company executives on setting advocacy priorities and positions within national trade associations. He also served on several state-level business association boards and policy committees to establish priorities and positions and engaged with policymakers and stakeholders directly to achieve consensus. He worked on steering committees for several voter initiative campaigns and developed a broad advocacy campaign strategy for a novel transportation policy designed to reduce life-cycle transportation emissions from current and future vehicles.

David began his professional career as an environmental engineering consultant working on air pollution control and permitting, air toxics and water quality assessments and monitoring for clients in oil and gas, aerospace, mining, food production, utilities, and government.

David holds a B.S. in Environmental Biology and B.A in Applied Ecology from the University of California, Irvine, and a M.S. in Environmental Engineering from the University of Southern California.
