Why the cookie has to crumble
There are several reasons why the death of third-party cookies has become overdue.
Research consistently indicates increasing concern about data privacy, with younger consumers particularly worried. Policymakers have intervened in response, seeking to crack down on sales tactics that effectively plunder consumers’ web histories without their prior knowledge, in order to exploit their purchasing impulses. The EU’s General Data Protection Regulation (GDPR), which dates from 2016, served notice on third-party cookies in Europe. A number of US states have launched similar regulation. Even China has its own version.
Early implementation of these regulations, moreover, has only hardened attitudes. European users are now offered a consent pop-up every time they visit a website – a significant source of irritation. And some advertisers’ use of “dark” or deceptive patterns, such as forcing users to take a survey before they can opt out of personal data collection, has added to the anger, galvanizing support for privacy campaigns.
Another driver of the shift away from third-party cookies is growing awareness of the environmental impact of the technology sector. Concern around the increasing carbon footprint of data centers and the online advertising industry is a significant factor.
Indeed, a single digital ad campaign that receives one million impressions is estimated to generate the same volume of emissions as a round-trip flight from Boston to London. According to Scope3, programmatic advertising alone generates 215,000 metric tons of carbon emissions every month across five major economies. That’s the equivalent of burning about 24 million gallons of gasoline.
Regulators are prepared to work with the advertising industry to ease the transition, but they won’t bow to pressure to change course. Indeed, in many jurisdictions, regulators are already getting tougher with Big Tech. In the US, for example, the Department of Justice’s law suit against Google, which alleges monopolistic practices in Google’s adtech businesses, is scheduled to reach court in September.
