Liane Randolph, the Chair of the California Air Resources Board (CARB), is set to retire on September 30, 2025. Governor Gavin Newsom has announced that Lauren Sanchez, his Senior Climate Advisor, will take over as Chair.
This change comes at an important time for California, as the state pushes for ambitious climate goals while managing emissions regulations and economic growth. Randolph has led significant initiatives toward a carbon-neutral California. Sanchez is known for her role in crafting this bold climate strategy and is expected to continue that momentum.
Randolph’s extensive career spans over 20 years in environmental and utility regulation, including her role at CARB since 2021 and as a commissioner at the California Public Utilities Commission. She has worked tirelessly to meet the state’s climate targets and advocate for communities most affected by pollution.
CARB has been a crucial force for environmental protection since its founding in 1967, responsible for regulating air quality and implementing greenhouse gas limits. Randolph’s predecessor, Mary Nichols, set high standards, and Randolph expanded on that legacy, navigating complex challenges in climate policy.
During her time as Chair, Randolph achieved several key milestones:
- Developed the 2022 Scoping Plan to reach carbon neutrality by 2045.
- Implemented a ban on new gasoline-powered vehicles by 2035.
- Ended agricultural burning in the San Joaquin Valley to cut down pollution.
- Expanded the Community Air Protection program to many at-risk communities.
- Directed nearly $10 billion in investments through Cap-and-Trade revenue.
- Launched innovative projects, including satellite technology for methane leak detection.
As Sanchez prepares to step in, she brings a diverse background in climate policy and a commitment to science-based solutions. Her experience includes advisory roles at the federal level and significant educational credentials in environmental studies.
Governor Newsom has highlighted Randolph’s contributions, calling her service an “honor” and praising Sanchez as a trusted advisor ready for the challenges ahead. Sanchez’s leadership will be vital as California faces ongoing environmental challenges, including legal battles over emissions regulations and the pressing need to manage wildfires while ensuring equity in climate initiatives.
Experts point out that California’s climate efforts are critical not just for the state but also as a model nationwide. According to a recent survey by the Public Policy Institute of California, 78% of Californians support stricter state regulations on air pollution, showing a strong public desire for action on climate issues.
Looking ahead, Sanchez is expected to focus on strengthening community protections, enhancing accountability for corporate emissions, and promoting zero-emission vehicles. The transition of leadership at CARB signifies a pivotal moment in California’s environmental journey, promising to uphold and advance the fight against climate change.
As CARB aims to maintain its leadership role, the agency’s continuous innovation will be key to tackling emerging climate threats effectively. Stakeholders, including environmental groups and vulnerable communities, anticipate a robust approach from Sanchez that will drive forward the state’s clean energy agenda.
In summary, Liane Randolph’s retirement marks the end of a significant era in California’s environmental governance. With Lauren Sanchez at the helm, backed by Governor Newsom, CARB is poised to lead California through the challenges and opportunities that lie ahead in the fight against climate change.
