Joseph Worswick, VP EMEA and Global Head of Sustainability, OpenX. In conversation with John Horsley.
Why Sustainability in Advertising Is a Commercial Imperative
0:0028:00Why the first carbon-neutral ad network proves sustainability and programmatic performance are not in conflict
Joseph Worswick wears two hats at OpenX: VP EMEA and Global Head of Sustainability. OpenX became the first ad network to achieve certified carbon neutrality, a milestone that changed the conversation about environmental responsibility in programmatic.
In this conversation Worswick explains why sustainability in advertising is a commercial discipline as much as an ethical one, how eliminating MFA sites simultaneously reduces waste and improves performance, and why independent third-party validation rather than self-reporting is the only credible approach.
Tell us about your dual role at OpenX
“I wear two hats. VP of EMEA, managing our buyer development team with brands and agencies. And Global Head of Sustainability covering internal sustainability practices and educating the market on what they could be doing.”
Worswick describes a dual role reflecting the belief that sustainability cannot be siloed from commercial operations.
Tell me about becoming the first certified carbon-neutral ad network
“We were the first ad network to become carbon neutral and get that independently certified. Not self-reported. We worked with third-party entities that can assess what we are doing as a company and really validate that.”
Certification distinguishes genuine achievement from marketing positioning.
How does sustainability in programmatic improve commercial performance?
“Eliminating made-for-advertising sites from the supply chain reduces carbon-intensive page loads and ad calls without delivering genuine audience value. Eliminating them reduces the environmental footprint and improves performance at the same time. Clean supply and better performance are aligned.”
The clearest illustration that sustainability and performance are not in conflict.

“We are one of the founding partners with AdNet Zero. We value that partnership and what they are striving to do for the industry. Without industry-wide standards for measuring advertising-related emissions, sustainability claims cannot be compared or verified.”
AdNet Zero is the infrastructure that makes individual commitments meaningful at scale.
What can brands and agencies do to improve advertising sustainability?
“Start by measuring. Understand the carbon footprint of your campaigns and supply chain choices. Then work with partners who have independent certification. The industry is at an early stage but the direction is clear.”
Pragmatic guidance for organisations at the beginning of the sustainability journey.
