AB 2674 California Assembly · 2025-2026 Regular Session

State Air Resources Board: internet website: methane emissions data.

Summary

The California Global Warming Solutions Act of 2006 designates the State Air Resources Board as the state agency charged with monitoring and regulating sources of emissions of greenhouse gases. Existing law requires the state board to approve and begin implementing a comprehensive short-lived climate pollutant strategy, as specified, to achieve a reduction in the statewide emissions of methane by 40% below 2013 levels by 2030, and requires methane emissions reduction goals to include specified targets to reduce the landfill disposal of organics. The state board has implemented regulations pursuant to the act for the purpose of reducing methane emissions from municipal solid waste landfills. This bill would require the state board to post on its internet website temperature and monitoring data received by the state board regarding methane emissions from landfills.

MODERATE

The Senate amendment adds an entirely new topic to AB 2674: it now requires the State Air Resources Board to publicly post temperature and monitoring data on methane emissions from landfills on its website. The original financial abuse prevention provisions for depository institutions are retained but repositioned after the new environmental sections. The bill's title was expanded to cover 'air pollution' in addition to 'financial institutions.'

SCOPE

A new Section 1 adds legislative findings and declarations about California's 2010 landfill methane regulations (LMRs), noting opportunities to improve them using new technologies and data, and that publicly posting data will increase trust and transparency for communities near landfills.

The bill's short title was expanded from 'relating to financial institutions' to 'relating to financial institutions. air pollution,' reflecting the addition of the environmental transparency requirement.

REQUIREMENT

A new Section 2 adds Health and Safety Code Section 39732, requiring the State Air Resources Board to post on its internet website temperature and monitoring data it receives regarding methane emissions from landfills.

TECHNICAL

The original financial abuse provisions (Division 21, Financial Code) were repositioned after the new methane sections but their substantive content appears unchanged. The section numbering for the financial code provision still reads 'SECTION 1' in the amended text, which appears to be a drafting error since it should logically be Section 3.
