TL;DR

Consent Mode v2 adds two new required parameters: ad_user_data (consent to send user data to Google for advertising) and ad_personalization (consent for personalised advertising), joining existing analytics_storage and ad_storage. Required for advertisers using Google services in the EEA/UK. Implement via a CMP integrated with GTM: set default consent state (denied for EEA, granted for other regions), CMP updates consent when users make choices, Google tags automatically adjust (cookieless pings when denied, full tracking when granted). Consent Mode enables modeled conversions — Google estimates conversions from non-consenting users using machine learning.
