Net Zero Advertising: Marketers' Key Role in Achieving a Carbon-Free Future

From Data-Driven Solutions to Authentic Sustainability: Why the Advertising Industry Must Lead the Shift Toward Net Zero

A Mark: Advertising’s Role in the Climate Crisis

The impacts of climate change are no longer distant—they are being felt right now, across the globe. From Hurricane Milton to the rage of wildfires, rise of sea levels, and ecosystems teetering on the brink, one thing has become clear: no industry is exempt from accountability, and every action counts. Advertising, often seen as a driver of consumerism, now stands at a pivotal crossroads.

Despite its undeniable cultural influence, advertising also has a significant, often overlooked, environmental impact. A staggering 1 metric ton of CO2 is emitted for every million digital ad impressions, and considering the sheer scale of digital advertising, these emissions quickly add up. It’s a hidden cost we can no longer afford to ignore.

But there is hope. Advertising has always had the power to shape mindsets and drive societal change. If harnessed correctly, it can lead the charge toward sustainability. Ad Net Zero , an ambitious global initiative, is proof of this vision. Their mission: to bring the advertising industry to net zero emissions by 2030. It’s an audacious goal, but one that’s absolutely achievable—if we, as marketers, rise to the challenge.

Now, more than ever, the responsibility falls on us to act. The tools are there. The urgency is undeniable. And the stakes could not be higher.

A Brand: Ad Net Zero ’s Path to Sustainable Advertising

Ad Net Zero is not just another sustainability initiative—it’s a blueprint for change. Its five-point plan outlines clear, actionable steps that can be implemented today, allowing companies of all sizes to make a tangible difference in their carbon footprint.

Ad Net Zero’s framework centers on five practical actions:

1. Reducing emissions from all aspects of advertising production, distribution, and media planning.
2. Using carbon calculators to track and manage the environmental impact of every campaign.
3. Transitioning to renewable energy sources in every stage of the advertising process.
4. Encouraging sustainable consumption behaviors among consumers by promoting eco-friendly products.
5. Providing education and resources so that everyone in the advertising industry knows their role in cutting emissions.

A cornerstone of this approach is the AdGreen carbon calculator, a tool designed to measure the emissions generated by every stage of a campaign. From the energy used in creative production to the emissions produced by ad servers delivering impressions, it gives marketers precise insights into where their environmental impact lies. Armed with this data, brands can make informed decisions to reduce waste, optimize resources, and create campaigns that are both effective and sustainable.

Yet, as we know from the Ad Net Zero Global Media Sustainability Framework , the challenge goes beyond just measuring emissions—it’s about transparency. Media emissions account for up to 55% of total emissions for some companies, yet many brands struggle with accurate reporting and transparency. This lack of clarity breeds consumer distrust. Now is the time to change that.

In an era where 58% of global executives admit to greenwashing, consumers are increasingly demanding authenticity. Vague sustainability claims no longer hold weight. Ad Net Zero emphasizes that real progress is rooted in data-backed action. Brands must show their work—transparency is non-negotiable.

Ad Net Zero is helping our industry avoid two common pitfalls: greenwashing (overstating sustainability efforts) and green-hushing (under-reporting progress to avoid scrutiny). Both damage trust with consumers. The solution? Proving our efforts with data and making sustainability a normal part of how we do business, not just a special initiative. Marketers must remember: the journey to sustainability isn’t about being perfect. It’s about being honest, making progress, and demonstrating that progress with concrete numbers.

An Impact: Practical Actions for Marketers to Achieve Net Zero

The advertising industry is at a turning point, and marketers hold the key. Here are some steps you can take to immediately begin reducing your carbon footprint and contribute to the net zero mission:

1. Measure and Optimize the Carbon Footprint of Every Campaign

It starts with data. Use tools like the AdGreen carbon calculator to measure the emissions generated by each campaign. By identifying the stages that contribute the most to your carbon footprint—whether it’s production, distribution, or the ad servers—you can make targeted changes. For instance, reducing the number of unnecessary impressions or compressing digital files can dramatically cut emissions.

Improving ad targeting alone could reduce energy consumption by up to 30%, a significant step toward lowering emissions. These are not small numbers—they represent real impact.

2. Choose Sustainable Partners and Platforms

Marketers must be deliberate about who they work with. Every partner in the advertising chain—from production houses to media platforms—should share your commitment to sustainability. Opt for partners powered by renewable energy, and favor platforms that have strong sustainability credentials. It’s no longer enough to focus on cost-efficiency alone; sustainability must become a core metric.

Similarly, think about media optimization. Timing your ad deliveries during off-peak energy periods or selecting low-energy ad formats can contribute to significant carbon savings. These small but thoughtful actions add up.

3. Reduce, Reuse, and Recycle Creative Assets

We’ve all seen it: brands producing far more creative content than they ever use. This overproduction leads to unnecessary waste. By streamlining the production process, you can reduce the environmental toll of your campaigns. Additionally, optimizing digital creative for energy efficiency—by compressing files, for example—can significantly lessen the strain on servers.

4. Be Transparent with Consumers About Your Sustainability Journey

It’s time for honesty. In a world where greenwashing has damaged trust, consumers crave transparency. They want to know exactly how your brand is contributing to a sustainable future, and they expect you to back it up with real data. Don’t be afraid to share where you are on your journey, even if you haven’t reached your goal yet. What matters most is that you’re committed and making progress.

5. Leverage Media to Promote Sustainable Behaviors

As marketers, we have the power to shape not only what people buy, but how they behave. Use your campaigns to encourage sustainable choices—whether it’s reducing energy consumption, choosing eco-friendly products, or rethinking plastic use. Advertising can—and should—be a force for good.

Conclusion: The Time to Act Is Now

The path to net zero advertising is not an option—it’s a necessity. As marketers, we have a responsibility not just to our brands or our bottom lines, but to the planet. The stakes are higher than ever, and the time for action is now.

By using the power of data, aligning with sustainable practices, and embracing transparency, we can revolutionize how advertising operates. It’s time to step up and lead the charge.

Advertising has always been about shaping culture. Now, let’s use that power to shape a sustainable future.
