Digital advertising is now linked to 5.5% of global greenhouse gas emissions, roughly 450 million tons of CO2e each year, even as ad budgets keep climbing. One reason stands out in the dataset, programmatic and real time bidding drive huge server demand while high bandwidth video and repeated retargeting turn “engagement” into energy use. The contrast gets sharper when you compare formats and targeting styles, from video ads at 1.2 tons of CO2e per 1,000 impressions to static images at 0.3, so the real question becomes what is being optimized and what is being overlooked.
