Regulatory Guidance Documents

ARB’s cap-and-trade regulation, which appears at sections 95800-96023 of title 17, California Code of Regulations, is a set of rules that establishes a cap on greenhouse gas emissions and provides market-based compliance mechanisms to covered entities.  

ARB staff prepared an Cap-and-Trade Applicability Guidance to describe associated applicability requirements.

How to "Opt-in" to the Cap-and-Trade Program?

Entities that are in one of the sectors covered under the Cap-and-Trade Program, but that are not already covered entities because they emit less than the threshold of 25,000 MTCO2e annually, may choose to opt in to the program.  An opt-in covered entity is an entity that voluntarily chooses to participate in the program and agrees to be subject to all rules and requirements applicable to covered entities.  In order for an entity to voluntarily participate in the Cap-and-Trade Program as an opt-in covered entity, we request that you submit the Opt-in Request Form to the California Air Resources Board’s Executive Officer for approval.  For further details on the opt-in process, please see the Opt-In Covered Entity Guidance Document.
