Internet ads – you probably see hundreds, maybe thousands a day without thinking about them. But it turns out the process for serving those ads involves a highly complex digital supply chain that generates 7.2 million tons of carbon emissions annually. That’s why ad-tech veteran Anne Coghlan is on a mission to decarbonize media and advertising with Scope3.  A lifelong lover of logic and problem-solving, Anne earned her Master’s at University College London in the Philosophy of Mathematics, later joining digital advertising company AppNexus in 2015. There she met future Scope3 co-founder Brian O’Kelley and helped to develop many of the technologies that underpin digital ad delivery today.  When Anne left the ad industry to join supply chain tech company Waybridge, she began to notice that a lack of consideration for sustainability and energy consumption existed across both industries.  So, in 2021, she reunited with O’Kelley and other AppNexus alumni to found Scope3, a public benefit corporation aiming to decarbonize advertising and media by better measuring the carbon emitted from digital display and video ads. In 2023, Anne made AdAge’s 40 under 40 list and secured the #2 most influential person in performance media on PMW’s Power 100 List, but the COO of Scope3 is just getting started.  Hear Anne Coghlan share how her love for math ultimately led to co-founding a startup, why online ads only scratch the surface of Scope3’s potential use cases, and what the future holds for decarbonized digital media.
