Smarter campaigns, cleaner footprint

By Avril Tomlin-Hood

Why sustainable digital media buying is a triple win for credit unions, and how to get started.

Sustainability is hugely important to mission-driven brands like credit unions. It aligns with your co-operative DNA, strengthens local communities, and helps members thrive—not just today, but for future generations.

Of course, digital advertising is also hugely important. It’s a cost-effective way for brands to target the right people with the right messages at the right times. However, behind every online ad are servers, algorithms, and data centres that consume significant amounts of energy. Every wasted impression burns energy, and energy burned is emissions added to our atmosphere.

This raises a tough question: how can you run effective campaigns without adding unnecessarily to your carbon footprint?

Houston… we have a problem. Studies reveal up to 40 percent of display advertising is wasted, while 8.5 percent of all paid traffic across major platforms is invalid.

That’s where sustainable digital media buying comes in. By choosing smarter strategies, credit unions can stretch their marketing dollars further while lowering their environmental impact. The result? Campaigns that perform better, are more cost effective, and leave a lighter footprint on the planet. Win, win, and win. 

The hidden costs of inefficient digital marketing

While our digital world comes with environmental benefits like reduced travel when meetings can happen online and less paper use, there is a downside. The internet, including the ads, email, tracking tech, and data centres that power it, generates a significant environmental toll. Here are some stats that raised our eyebrows when we read them:

• The digital ecosystem accounts for roughly 3.7 percent of global greenhouse gas emissions, on par with the entire aviation industry. (Source)
• Within that ecosystem, digital advertising alone may contribute about 1.7 percent of total emissions, rivaling sectors like shipping in its impact. (Source)
• A recent study found that web tracking adds about 21 percent more data transmission, leading to approximately 11 million metric tons of extra emissions each year. (Source)

Inefficient digital marketing just adds to the cost. Up to 40 percent of display ads are wasted, and 8.5 percent of paid traffic is invalid (source). Wasted ad impressions, inefficient targeting, and excessive digital complexity don’t just drain budgets, they also generate unnecessary carbon emissions.

Every wasted impression burns energy, and energy burned is emissions added to our atmosphere.

For credit unions, the stakes are especially high. Throwing away ad dollars and adding to digital pollution doesn’t align with your ethos of being grounded in community values, responsible stewardship, and trust.

Benefits of sustainable media buying

Reduce environmental impact
By cutting digital waste, such as invalid traffic, poor targeting, and excess impressions, you shrink your campaigns’ carbon footprint. It’s a statement of your community-first values as much as it is a marketing strategy.

Improve ROI
Target fewer, more qualified impressions, optimized in real-time. That means every ad dollar works harder and your campaigns perform better.

Support ESG commitments
Sustainable media buying helps credit unions demonstrate real commitment to environmental, social, and governance goals.Innovate for good
Emerging sustainable ad technologies and decarbonized media buying strategies are already reshaping how financial brands advertise (source). It’s an opportunity to take a lead.

Sustainable media buying proves you don’t have to choose between smarter campaigns and a cleaner footprint—you can achieve both.
