What's this about?
In this episode of ClearCast, ClearTrust founder Deepankar Biswas sits down with Phil Benedictus and Damien Thomson, the co-founders of Net Zero Media, to discuss how advertising emissions are being tracked, measured, and minimised.
What you'll learn:
The hidden carbon footprint of digital ads Discover how ad formats, programmatic delivery, and server infrastructure contribute to emissions.
How Net Zero Media tracks ad emissions Learn about their methodology for calculating carbon across media types—from display to video.
Where the ad industry is falling short Understand the regulatory blind spots, walled gardens, and data access issues slowing down green innovation.
How brands can cut emissions without cutting spend Explore practical ways to optimise creative, placement, and delivery while staying sustainable.
Top Takeaways
Ads are polluting more than you think The digital ad industry has a larger carbon footprint than aviation—yet few marketers are tracking it.
Skippable video is both costly and carbon-heavy Low engagement and high emissions make some formats doubly inefficient.
Measurement is the missing link Without emission visibility across media buys, sustainability is just a buzzword.
Sustainable advertising is performance advertising Reducing waste, optimising formats, and cutting carbon can all align with better ROI.
