Green Practices in Programmatic Advertising: Towards a More Sustainable Ecosystem
Environment, society, and economy.
These three pillars together form the foundation for building a truly sustainable programmatic environment. Sustainability is no longer optional; it is a shared responsibility. While we seek profitability, we must also ensure that our decisions respect both people and the planet. This is a challenge that we must embrace.
A Sector with Significant Impact… and Huge Potential for Change
Few realize that digital advertising has one of the highest carbon footprints within the technology ecosystem. According to various studies, it ranks in Category 3 (the most critical) due to factors such as:
The constant growth of the sector
The need for servers and massive data processing
The implementation of tools like artificial intelligence
The inefficiency of delivering ads on a massive scale, often poorly optimized
In addition, there is growing pressure: advertisers and agencies are demanding more sustainable practices from their partners. This will shape the future of programmatic advertising: those who adopt a greener supply chain will gain a competitive edge.
Why Should We Focus on Sustainability?
Let us return to the three pillars. Focusing on sustainability is not just an ethical gesture; it is also a smart and strategic decision.
1. Social and Environmental Awareness:
Reducing energy consumption
Adopting renewable energy
Responsible use of artificial intelligence
Active involvement of teams in the sustainability transformation
2. Efficiency and ROI:
A more precise and targeted ad delivery prevents wasted inventory
Improved return on ad spend (ROAS)
Reduced economic and environmental impact
In short: if we are more efficient, we are also more sustainable.
The First Step: Minimizing Wasted Impressions
One of the key strategies is avoiding inefficient ad impressions. The more times we show an ad to someone who does not need it, the more energy we waste—and the more budget is wasted.
This starts with effective human management. The Account Managers responsible for managing campaigns play a critical role:
Transparency in the supply chain
Clarity in key performance indicators (KPIs)
Audience optimization
Proper coordination with advertisers and trading desks
Although machines play a role, strategic vision remains human.
“Not Too Much, Not Too Little”: Balancing Targeting and Frequency
Sometimes, we fall into the trap of trying to reach the perfect user… too many times. However:
Excessive targeting leads to data processing overload
Inefficient retargeting overwhelms the user
High frequency can saturate the audience and reduce ad effectiveness
Technology is powerful, but sustainability requires balance.
Greener Partners: An Extension of Your Commitment
As in nature, everything is interconnected. The partners we choose to collaborate with matter as well.
Working with partners who use renewable energy, manage their data centers well, or implement sustainable practices strengthens your own green strategy. Ultimately, your chain is only as strong as its weakest link.
Measuring to improve
We cannot know if we are sustainable if we do not measure ourselves first. There are already tools available to calculate the carbon footprint of our campaigns, identify bottlenecks, and optimize processes. This is the first step toward meaningful change.
Supply Path Optimization (SPO)
The concept of Supply Path Optimization (SPO) goes beyond performance. It involves eliminating unnecessary intermediaries, reducing the number of resellers, and optimizing the programmatic supply chain to reduce costs and emissions.
A more direct and efficient supply chain is also a greener one.
More Efficiency in Formats
Did you know that video is one of the most energy-consuming formats?
Every video we load, every unnecessary part of the ad served and processed… it all adds up.
Fortunately, solutions already exist that optimize delivery and reduce the "weight" of ads, better adapting to the publisher and the user. Choosing the right formats is also a sustainable decision.
The Future We Will Build
Digital advertising is not going to stop. On the contrary, it will grow with AI, 5G, and new technological developments. However, this growth must be guided by a sustainable mindset.
In the short term, regulations will become stricter. Brands will be more demanding. And sustainability will no longer be a “nice to have”; it will become a fundamental necessity.
The future will no longer just be about targeting the right audience. It will be about doing so responsibly, protecting the planet for future generations.
Greenwashing should become a thing of the past. And social and environmental awareness should become the economic DNA of our industry.
What If We Start Today?
By embracing more eco-friendly strategies, optimizing ad delivery, using data more responsibly, and choosing the right partners, we can significantly reduce our carbon footprint.
The best part is that we will be actively contributing to the change towards a more sustainable, responsible, and human-centric digital advertising ecosystem.
