In Center for Biological Diversity v. County of Los Angeles (2025) 112 Cal.App.5th 317, the Second District Court of Appeal invalidated an EIR for a specific plan that contemplated expansive development on 12,000 acres in the Antelope Valley. The Court of Appeal held that the EIR improperly relied on the State’s cap-and-trade program to account for the project’s GHG impacts. In an unpublished portion of the opinion, the Court also held that the EIR’s analysis of wildfire impacts was inadequate.
Background
In 2019, the County of Los Angeles approved the Centennial Specific Plan, an expansive development on 12,000 acres of land in the Antelope Valley. The project, proposed by Tejon Ranch Company (Tejan), included residential, commercial, and industrial uses. Shortly after the County approved the project and certified its associated EIR, two environmental groups (Center for Biological Diversity and Climate Resolve) filed writ petitions alleging that the EIR lacked adequate analysis and mitigation regarding the project’s GHG emissions and wildfire risk.
The trial court granted the petitions in part. The trial court determined (1) the EIR’s discussion of GHG emissions improperly relied on state cap-and-trade regulations to reduce greenhouse gas emissions impacts below the level of significance, and (2) the EIR failed to analyze off-site wildfire impacts beyond the Centennial project site. Tejan appealed and the environmental groups cross-appealed.
The Court of Appeal’s Decision
The Court of Appeal affirmed the trial court’s decision—holding that the EIR’s discussion of both GHG emissions and wildfire risks were deficient.
GHG Impacts
The Court concluded that the EIR violated CEQA by applying the cap-and-trade program to the project’s estimated unmitigated emissions, minimizing the scope of the project’s impact and thus rendering the EIR prejudicially misleading.
The cap-and-trade program sets a statewide cap on GHG emissions and allows covered entities to buy, bank or sell allowances. Tejon argued that the EIR could utilize cap-and-trade offsets from the project’s energy and fuel suppliers in its analysis of the project’s GHG emissions even though it was not itself a “covered entity” under the program. In applying these “offsets,” the EIR concluded the program would reduce unmitigated emissions from 157,642 to 6,834 metric tons of carbon dioxide per year, and therefore, GHG emissions stemming from the project were “less than significant.”
The Court rejected this approach. According to the Court, though the project’s energy suppliers may be required to surrender compliance instruments to counterbalance the emission increases associated with the project’s electricity and fuel usage, CEQA does not contemplate the application of cap-and-trade offsets to a project’s GHG emissions if it is not a “covered entity” under the program. The Court explained that land use developments such as the Centennial project are not covered by cap-and-trade, and therefore, it was inappropriate to claim the project’s emissions from electricity and mobile sources would be offset by cap-and-trade.
The Court also deemed Tejon’s crediting of offsite emissions reductions to the Centennial project’s analysis unlawful as it violated the “additionality” requirement. Under CEQA Guidelines section 15126.4, subdivision (c)(3), GHG emissions reductions must be “additional” to other emissions reductions required by law, such as those under the cap-and-trade program. The Court stressed the importance of this requirement, noting that if non-additional projects were credited with offsets, it would result in the “double-counting” of emissions that have already been identified in calculating the emissions reductions necessary to achieve the cap-and-trade program’s statewide goals.
Tejon also argued the EIR’s GHG analysis was not misleading as the EIR did not actually claim “mitigation credit” for the emissions it asserted would be offset under cap-and-trade. The mitigation measures section of the EIR, however, included a table showing a 100-percent reduction in total emissions when accounting for cap-and-trade. That table was accompanied by an analysis which stated that cap-and-trade was a “lawful CEQA mitigation measure to reduce GHG emissions.” The Court concluded that this discussion would reasonably lead readers to presume that the cap-and-trade program would offset the project’s unmitigated emissions to zero, which was misleading.
Wildfire Impacts
The Court also affirmed the trial court’s ruling that the EIR’s wildfire impacts discussion was inadequate. Though the project included “substantial” off-site features that were linked to wildfires, the analysis concluded there were no dangerous fire hazards from such features without providing support to reach that conclusion. The Court found the discussion lacked any connection between the threshold criterion for off-site wildfire impacts and the County’s conclusion that the off-site features would not result in significant wildfire impacts.
The County concluded that overall wildfire hazard impacts would be reduced to less than significant with the application of Mitigation Measure 3-9, which required the preparation of an on-site Fuel Modification Plan in compliance with local fire safety ordinances. But the Court found that the EIR provided no specifics or analytical link as to how this mitigation measure would apply to off-site features or reduce off-site risks.
