The California Air Resources Board will hold a virtual public workshop to support the development of California’s Corporate Greenhouse Gas Reporting Program, established by Senate Bill (SB) 253 (Wiener, 2023), and the Climate-Related Financial Risk Disclosure Program, authorized by SB 261 (Stern, 2023). SB 219 (Wiener, 2024) amended both programs, extending certain deadlines and implementing other administrative changes. The workshop will consist of a morning session where staff will present an overview of the above-mentioned legislation, a timeline for regulatory development, and an overview of feedback received from stakeholders from our December 2024 California Climate-Disclosure Information Solicitation. Additional presentations will include a comparative analysis of greenhouse gas accounting and reporting mechanisms that currently exist across various regulatory and voluntary programs.
