On December 29, 2023, the Colorado Attorney General (the “AG”) announced that the Global Privacy Control (“GPC”) will become the first universal opt-out mechanism (“UOOM”) the AG considers valid under the Colorado Privacy Act (the “CPA”). Effective July 1, 2024, controllers subject to the CPA will need to treat Colorado consumers’ privacy preferences submitted through browser signals that conform to the GPC specification as consumers’ requests to opt out of data sale or targeted advertising.
