Ad Net Zero Australia – Shared Learning Forum – Reducing Media Emissions in Practice: WPP Media and OMG | 2025

In this session, we hear brilliant case studies of organisations reducing media’s emissions, through innovative use of data and technology.

Firstly, Matt Stephens from WPP Media shares how they use granular emissions data from Scope3 to identify the sweet spot between emissions and performance – at scale. This technology has already been scaled across many clients, with ambitions to roll out even further.

We then hear from Blake Power and Ashley Wong from OMG media agency Hearts & Science, about their pioneering work. Blake shows how reducing media emissions is a powerful performance lever, and Ashley shares the story behind the Renewables Engine that identifies low-carbon opportunities in real time.

This session is relevant for anyone involved in the media supply chain, from advertisers and agencies through to ad tech and vendors. Additionally, this is inspiring for anyone looking to decarbonise their supply chain, with learnings that are applicable across all areas.
