Consumer Reports, along with a coalition of other privacy organizations and advocates, submitted an application to the Colorado Department of Law urging certification of the Global Privacy Control as a legally recognized universal opt-out mechanism under the Colorado Privacy Act. The Colorado Privacy Act was enacted in 2021 and provides that consumers may use universal tools to opt out of data sales and targeted advertising. In 2023, the Colorado Department of Law promulgated regulations setting up a registry of certified universal opt-out mechanisms that companies will be legally required to respect. The Global Privacy Control currently has over 75 million active users, is open-source and free to implement for user agents and companies, and has already been legally recognized by California regulators as a valid opt-out mechanism. Consumer Reports is urging Colorado to include Global Privacy Control in its registry of recognized opt-out signals.
