AdTech’s Carbon Footprint: Curation’s the Solution

February 24, 2025

The digital advertising industry is evolving rapidly, but its environmental impact is often overlooked. Every online ad impression, auction and data transfer requires energy, contributing to carbon emissions. As programmatic advertising scales, so does its ecological footprint, making sustainability a growing concern in AdTech.

The Hidden Carbon Footprint of Digital Ads

Programmatic advertising relies on complex infrastructures, including data centers, real-time bidding (RTB) systems and ad exchanges. A single RTB transaction involves multiple players and processes, consuming significant energy. According to estimates, the global digital advertising ecosystem generates over 200 million metric tons of CO₂ annually—comparable to the carbon footprint of some small countries.

How Curation Can Drive Sustainable Advertising

Curation in programmatic advertising is emerging as a solution to minimise energy consumption while improving efficiency. Here’s how:

Reducing Bid Duplications: Traditional programmatic auctions waste energy with redundant bids. Curation streamlines transactions by eliminating unnecessary requests, reducing computational waste.

Enhancing Supply Path Optimisation (SPO): Curated marketplaces focus on quality, enabling direct, efficient inventory buying. This minimises data transfers and server loads, reducing carbon emissions.

Improving Targeting Efficiency: AI-driven curation targets high-intent audiences, cutting wasted ad spend and reducing unnecessary ad requests, lowering energy consumption.

Encouraging Sustainable Media Partnerships: Curation prioritises premium and eco-friendly inventory, supporting sustainable publishers with energy-efficient operations.

A More Sustainable Future for AdTech

As brands and agencies seek to balance performance with sustainability, adopting curated ad-buying strategies is a step in the right direction. Beyond carbon footprint reduction, curation enhances transparency, efficiency, and ROI—making it a win-win for both businesses and the environment.
