Interim GHG Emissions Thresholds of Significance Webinar

The Long Range Planning Division held a public webinar on Tuesday, September 8, 2020, to present draft "interim" greenhouse gas (GHG) emissions thresholds of significance. 

The PowerPoint presentation for the webinar is available here

A recording of the webinar is available here.


The Planning and Development Department (P&D) is proposing interim GHG emissions thresholds of significance. The thresholds will establish when an individual project creates significant cumulative impacts to climate change under the California Environmental Quality Act (CEQA). The interim thresholds will apply to new development in unincorporated areas of the County.

The County currently has GHG emissions thresholds of significance for industrial stationary source projects. The interim thresholds will apply to all other types of land use projects. Therefore, the County must update its Environmental Thresholds and Guidelines Manual to include the interim thresholds.

P&D staff is working with Ascent Environmental to develop the interim GHG emissions thresholds. P&D will release the draft interim GHG emissions thresholds in late August for public review, in advance of a public outreach meeting in early September. This website will update with more information as it becomes available.

P&D expects to take the interim GHG emissions thresholds of significance to the County Planning Commission on October 14, 2020.

The County is also updating its Climate Action Plan and expects to complete the update in 2022. These interim GHG emissions thresholds of significance will be reviewed as part of the CAP update, and will become adopted as final thresholds upon adoption of the updated CAP.
