    Jon Costantino has 19 years of professional experience finding solutions to problems between business and all levels of government. He has worked in the field of resource protection directly in the public and private sectors, specializing in climate change policy and air pollution control. He is currently a registered lobbyist with the State of California, the Executive Director of the Association of Carbon Market Participants (ACMP), and splits his practice between regulatory and legislative work. In 2011, Jon was appointed by California Governor Jerry Brown as a member of the Central Valley Regional Water Quality Control Board. The Board is one of nine regional state agencies responsible for water quality in California.

    After graduating with a Civil/Environmental Engineering degree from UC Davis, he began his public sector career in permitting and enforcement at a local air quality district. Prior to leaving for the private sector, he managed California’s historic AB 32 climate change program out of its infancy within the California Air Resources Board’s Office of Climate Change. He has developed internationally followed policies and implemented programs with billion-dollar implications to California’s largest industries. As a Senior Advisor in the firm’s Government and Regulatory Practice Group, his focus is on managing complex issues for clients in the area of environmental protection, specializing in California’s climate change and clean energy programs. Mr. Costantino enjoys the multidisciplinary aspect of the position, which frequently requires working with attorneys throughout the firm on a wide range of issues and practice areas.

    He has been a highly sought-after source of information and opinion by mainstream and industry-specific media. He has provided live TV and radio interviews on the subject of AB 32 and climate change policies, and is a recognized authority in the field of climate change regulation.

    In addition to his local engineering work and his climate protection management experience,  Mr. Costantino was the lead legislative analyst at the California Air Resources Board where he made technical and policy recommendations on both state and federal legislation. During his seven years in California’s Capitol, he built a broad portfolio of expertise covering California’s biggest industries and most powerful stakeholders, including water, agriculture, construction, energy and all aspects of transportation fuels.
