Clicks and Climate: How Digital Advertising Impacts the Carbon Conversation

Nick Maumus, Assistant Media Planner

Sustainability is a buzzword in every industry, and it will only become more prominent as the climate crisis continues to grow. But when “carbon emissions” is mentioned in conversation; we default to thinking about the energy sector, big oil companies, and that dreaded Honda Civic revving its engine every early morning. What we forget is the prevalent and material impact caused by the digital world, and more specifically, advertising and media.

Firstly, carbon emissions in digital advertising are very real and have a much more prevalent impact than most of us realize. For context; 1M impressions creates 1 metric ton of CO2e (One passenger on a round-trip flight from Boston to London), and Google serves about 30 billion on an average day! 

Scope 1, 2, and 3: Categorizing Carbon Emissions

In terms of how we identify and categorize these carbon emissions; there is the Scope framework, which is divided into three categories.

When we think of this in the context of media, the supply chain is not necessarily raw materials or manufactured inputs as might be the case for a computer chip manufacturer. For brands and agencies, the supply chain is most evident in the programmatic marketplace, where each publisher has multiple bid requests for every ad slot, and buyers are bidding on it all.

Additionally, every transaction and exchange of data that occurs on the programmatic supply chain releases a variable amount of carbon emissions; the larger and less efficient the supply chain, the more carbon is emitted. Publishers often duplicate ad bids for the same slot on overlapping DSPs and direct partnerships, leading to unnecessary and wasted transactions.

Measuring Media Emissions

Media emission measurement partners, such as Scope3, have entered the space to analyze programmatic publishers and raise awareness of their environmental impact. They provide a comparative ranking of the publisher’s total carbon footprint, their programmatic supply chain, and how their footprint breaks out among ad selection; media distribution; and creative delivery. 

Another valuable resource is a study conducted by Fifty-Five titled The Carbon Footprint of Media Campaigns. This public study examines the carbon emissions generated by a one-month mock omnichannel media campaign. The fascinating part of this study is how they were able to analyze the emissions from the four digital channels they chose to include. In their findings, they discovered that 323 Tons of CO2e were released over the course of one-month. However, if advertisers take sustainable digital advertising best practices into account, they can bring that total down on average 32% to 218T. 

Sustainability and Advertising: A Win-Win Partnership

Every impact, whether large or small, makes a difference in the climate issue. It is important that we spread awareness and resources to educate ourselves, and our industry, on the ways we can each drive change. In the context of programmatic supply chains, MFA (Made for Advertising) sites and ad-cluttered platforms are much less environmentally friendly—and on top of that, advertisers typically avoid these sites anyway. 

So, an incentive makes itself clear; a more efficient campaign is a cleaner campaign, and a cleaner campaign is a more effective campaign. All in all, understanding areas of improvement while maintaining the integrity of our campaigns can lead to bottom line improvements and notable environmental impacts. Next time you are in planning or see an innovative media placement, I invite you to explore the associated carbon journey and how you might be able to include sustainable digital advertising practices into your value chain. 

AdAge: Hot Takes From Upfronts 2025

Despite the evolving media landscape and continual doomsaying about the death of linear, upfronts arguably remain the most pivotal week of the year for TV networks. Billions of dollars in ad commitments take shape during the annual industry showcase, providing a view into the evolving dynamics of media buying—and the tech that will measure those investments.

Ad tech played a pivotal role in the 2025 upfronts and NewFronts, with Google, Yahoo, Netflix and Fox driving home the importance of AI- and data-driven ad tools for marketers. Gen Z once again dominated the demographic conversation, with tailored lineups and targeted content, while the dynamics between streaming and legacy networks continued to play out against a backdrop of Trump’s tariffs, increasing economic uncertainty and a fragmented media landscape. Amid so much disruption and reinvention, we turned to the experts for their key takeaways from TV’s biggest week.

Walled Gardens: Is the Grass Really Greener?

Katie Flores, Associate Director of Programmatic Media Investment

According to a report published by AI Digital, 83% of digital ad revenue is projected to be controlled by Walled Gardens by 20271. A walled garden refers to how platforms such as Google, Meta, Apple, and Amazon control their platform insights and information such as ad inventory, user data, and performance metrics, limiting outside access.

The report also states that 90% of consumers spend their online time within these walled garden environments. Wow, 90%! That means only 10% of users spend their online time engaging with media that we can gain insights from and create leverageable audience segments to optimize against. Walled Gardens can pose a risk to the media ecosystem but also have undeniable benefits.

What is a Walled Garden & Why Are They So Attractive?

Walled Gardens have dominated the media industry for years. But why? Well, the attraction of working with Meta or Netflix for example should be obvious. The latter reported that their daily average viewing duration was two hours and in 1H’24, consumers streamed over 94 billion hours of content2. Mass reach is an understatement. And Meta has mass reach locked down. Facebook has over 3 billion users. The rich, complex, and extensive user data stores gathered from those 3 billion users are just one of the many things that sets Meta apart. 

With the further deprecation of cookies and tracking capabilities, these Walled Garden’s first-party data stores will become even more sought after by marketers looking to gain deeper insights into their consumers. Their precision targeting capabilities are vast, the platforms are widely recognized and engaged millions of times a day, and buying on a platform such as Meta allows for a complete campaign journey from launch, campaign optimizations, and campaign wrap-up measurement. 

Along with the ease of working with a partner throughout the campaign cycle, Walled Gardens can also provide a full view into the consumer journey from discovery to purchase

The Dark Side: Transparency and Black Box Measurement

All of this sounds incredible, but what does it mean for a platform that isn’t a Google or Apple, or Meta? Well, sometimes the grass isn’t always greener inside of these Walled Gardens. Issues such as transparency, data collection and ownership, inflated inventory and fee costs, and trust are just the beginning.

Transparency has always been a hot topic when it comes to the Googles and Metas of our world. These companies have the right to withhold or provide a client with any information or data that they choose. And the transparency issue goes far beyond data but also applies to how the company’s ad tech algorithms work, how ads are served and where, and what audiences are seeing them. This is often referred to as Black Box Measurement and it’s something that the advertising industry is just starting to unpack and examine. How do you challenge and trust a platform that acts as judge, jury, and executioner without third party validation? This is a question that we as media buyers and planners should ask ourselves daily.

The Automation Illusion: When Simplicity Hides Complexity

Since third party measurement partners aren’t allowed to be utilized within these platforms, brands must rely on the honesty of the publisher, that they are providing them with the correct data, and that the data that brands can ingest into the platforms are actually being used for their intended purposes. The lack of transparency seems to be only increasing, under the guise of enhanced performance through automation. 

For example, Google’s Performance Max and Meta’s Advantage+ are newer products that significantly reduce advertiser control of where ads are serving and how they are appearing. While these platforms promote simplicity and automation, allowing their algorithms to handle the work as ‘best practice,’ good advertisers must scrutinize these directives, recognizing the platforms’ inherent drive for monetization. 

While we can’t directly track and validate these platforms with 3rd parties, we can conduct test & learns and other forms of measurement to make our own informed decisions. 

Scrutiny around transparency has come from not only platform users but government officials as well. This pressure has led to some closed ecosystems experimenting with ‘clean rooms’ to provide partners with more insights than ever before. For example, in 1H’24, Amazon launched AWS Clean Rooms ML. 

This product allows Amazon partners to use AWS’s proprietary machine learning technology to create audience modeling and predictive insights without Amazon having to disclose any of their raw data. It’s a step in the right direction but is it enough?

History Repeats: From Prime Time TV to Prime Video

I often compare Amazon Prime and Netflix, who just recently announced they will stop reporting paid subscribers come 1Q’25, to how media buyers viewed the Prime-Time daypart ‘back in the day.’ Before we had the granular and specific audience data reporting tools, us media buyers would pay ABC, CBS, and NBC exorbitant costs to air in those three to four hours of content a night solely because Nielsen’s Household reporting panel of 0.01% of the US population told us those shows had the highest ratings on tv. 

We trusted this data because of Nielsen’s longtime standing as a consumer reporting titan, similar to how we in the media industry trust the statistical data that Meta and Amazon supply us with. Looking back, we now know that Nielsen’s murky in-home panel system fraudulently reported inaccurate age, sex, and content data resulting in millions of ad dollars lost to inaccurate targeting tactics3. Even when it comes to billion-dollar, household institutions, question, examine, and challenge everything.   

Thus far we have covered issues with transparency, concerns over data ownership, and Black Box measurement processes. Which leaves us with one last thing to discuss, and that’s money. The premium content that a Netflix or an Amazon Prime provides to us consumers sure does come at a premium cost. 

In addition to award-winning content, their large user bases/scale, time spent in-platform, white-glove service offerings, measurement capabilities, and high-quality ad experiences mean that our bargaining power goes out the door if we want to continue engaging with our clients’ in-platform target audiences. 

All in all, Walled Garden pricing can be as inflated as these companies want since media buyers must purchase their content via Direct IO and not on the open market. Demand is high and supply is low. Econ 101!  

Regulatory and Industry Pushback: Cracks in the Walls

We are at the whim of these Walled Garden companies, and they know they hold the chips, but some government officials, tech companies, smaller publishers, and media buyers are trying to reclaim some of this power. On a global scale, the EU’s Digital Markets Act of 2023 has put a spotlight on creating fairer and more competitive marketplaces by regulating Walled Garden platforms from abusing their position in the market. 

In the United States, the California Consumer Privacy Act allowed California residents the right to share or exclude their data, and US antitrust laws aim to reduce monopolization of certain sectors where it has occurred. 

On a smaller scale, publishers, agencies, and ad tech companies are coming together to collaborate on solutions such as clean rooms, contextual and AI predictive targeting methods, building identity alternatives like UID 2.0, and sharing transparent rate/fee cards to challenge the way these closed ecosystems operate. 

For example, LiveRamp is continuing to grow its global data community to help solve inadequacies in available measurement and audience insights. While these Walled Gardens are closing in, innovations in data collection and collaboration from every corner of the industry are expanding.

Looking Ahead: Will 2026 Bring More Openness?

As we look at the rest of 2025 and 2026, will we see Walled Gardens continue to grow or will we see open access to their inventory across different platforms and increases in data and measurement transparency? 

For example, smaller-scale DSPs plan to start selling Amazon Prime inventory beginning in 2H’25, which will remove the costly commitments and barriers of entry of buying directly with these partners. Hopefully, this trend continues in a forward direction and more and more Walled Garden platforms will follow suit as we move into 2026.

Balance the Power but Don’t Ignore the Value

In conclusion, Walled Garden companies are necessary for the industry and economy, have undeniably advanced targeting capabilities, captivating and alluring content, and billions of users who engage with their platforms for hours on end. 

However, the lack of transparency, accountability, data ownership and measurement, and insights into where and when ads run is a problem that simply cannot be ignored. When planning for 2026, keep an eye out for publishers with ad tech partnerships that can provide complete clarity into their data control and usage capabilities, reporting and measurement potential, transparent cost and fee structures, and last but not least, partners you can trust.

Time, Safe, Stay: How Real Stories Drove Real Impact on International Epilepsy Day

This year, on International Epilepsy Day, Epilepsy Ireland and Connelly Partners joined forces once again to launch a powerful nationwide campaign focused on one clear message: Time. Safe. Stay. It’s a simple mantra — but one that could make all the difference if you ever witness someone having a seizure. 

Turning Stats Into Stories

How do you take a public health message and make people really care? You make it personal.

Backed by robust research from Amárach, the campaign centred around the lived experiences of people with epilepsy. Research showed that 88% of people in Ireland believe there’s a lack of understanding of epilepsy amongst the general public. So we got to work – putting real voices, real faces, and real emotions front and centre. These weren’t just testimonials. These were open, honest conversations about life with epilepsy. Fear. Frustration. Strength. Hope.

By showcasing these stories, we aimed to create empathy, spark curiosity, and ultimately, leave a lasting impression about the importance of seizure first aid — Time. Safe. Stay.

A Multi-Platform Approach That Hit Home

To maximise impact, we launched a multi-channel campaign — from powerful digital storytelling to social media, DOOH and more – ensuring visibility at both national and regional levels. Media volunteers bravely stepped up to share their experiences with press. Interviews delivered a deeply human look at epilepsy’s daily challenges.

Listen to the full Supercharged (RTE Radio 1) interview here.

A video campaign, voiced by legendary Radio DJ Rick O’Shea, was broadcast on Sky Television. 

Digital out-of-home adverts brought the message into busy shopping centres and high-footfall areas throughout the Capital and regionally, as well as in Galway’s Eyre Square. 

Digital Display ads featuring our media volunteers ran across various digital platforms, providing lots of touch points for the Irish public to engage with this important message.

Social media lit up – and were amongst the most successful strands of this multi-faceted campaign. TikTok alone delivered 1M+ impressions,  reaching 538k accounts with an exceptional 17.36% engagement rate — well above platform norms.

Across META (Facebook and Instagram), the campaign reached 570K users, blowing past the original goal of 157K, with an impressive 2.78% engagement rate, significantly above the 0.20% industry benchmark. 

Our Digital Audio campaign over-delivered – achieving a 90% Listen Through Rate (LTR) and reaching 40K+ unique users

The results proved that human connection is still at the heart of effective storytelling.

The Intersection of AI, Brand Safety, and Sustainability in Ad Tech

Abby Versaggi, Assistant Programmatic Media Buyer

I recently attended Scope3’s inaugural Landscape conference in New York City, where I had the opportunity to explore not only Scope3’s new and potentially game-changing ad tech but also the key challenges facing our industry—brand safety, supply chain optimization, sustainability, and the evolving role of AI. Here are some of the top takeaways from the conference:

The key themes of the day were safety, sustainability, and growth, with a strong focus on implementation. If a new technology can’t be demonstrated, used, deployed, and mastered, it won’t be adopted effectively—making proper execution essential for industry-wide change.

The Challenges of Brand Safety in Programmatic Advertising 

Current brand safety tools have fallen short, and the industry—particularly in programmatic advertising—continues to struggle with transparency.

Sustainability, media quality, and brand safety are all interconnected. A lack of innovation has made it difficult for advertisers to access URL- or page-level data, creating significant challenges in transparency. 

AI-Powered Solutions for Brand Safety

Recognizing the need for a better approach to brand safety, Scope3 announced an AI-powered brand safety and suitability product. This new tool gives advertisers greater control over the content their ads appear on while reducing unnecessary content blocking.

We know AI uses a lot of energy to make decisions. So does the current digital advertising ecosystem, especially programmatic. The differences are:

  1. We have the chance to develop AI systems with sustainability in mind, unlike how the programmatic ecosystem was developed. 
  2. AI can also replace and streamline tech, as it is more forgiving of inconsistent data due to its ability to learn and model.

For example, blocklists and category filters have traditionally flagged keywords on a page without considering their context, often leading to the blocking of safe content. Scope3’s AI-powered brand safety agent addresses this by analyzing the full context of any piece of online content, ensuring that decisions align with a brand’s exact requirements. Advertisers can also provide feedback to refine the model over time.

Low-quality and Made-for-Advertising (MFA) sites host excessive low-value content and drive inefficient ad spend. With custom AI agents, advertisers can avoid bidding on these sites; therefore, reducing unnecessary energy consumption and wasted ad dollars. 

Custom AI Models For Greater Transparency

This new ad tech allows brands to build their own models based on their business goals, and criteria for brand suitability. It can be integrated into Demand-Side Platforms (DSPs) and Supply-Side Platforms (SSPs) to offer a more comprehensive view beyond just a site name. 

Additionally, it explains to advertisers and publishers why content was blocked and allows them to adjust parameters as needed. This helps solve the black box problem that many AIs face by making data-driven decisions more observable and understandable. 

AI’s Role in Sustainable Programmatic Advertising

If we don’t address the inefficiencies in programmatic advertising, we risk wasting millions of tons of carbon. AI has the opportunity to add to these emissions or counteract these inefficiencies. Scope3 has developed a way to do the latter, ensuring sustainable evolution of the programmatic landscape.

Celebrating Women at SXSW: A Look Inside The FQ Lounge

Claire Eisenberg, Director of Corporate Communications

This year, we kicked off International Women’s Day at The Female Quotient Lounge at SXSW. The Female Quotient empowers millions of women globally by fostering inclusive workplace cultures through community building and visibility initiatives. As an agency that knows a thing or two about the importance of understanding your audience, their mindsets and motivations, this activation spoke to us.

As we entered the lounge, we were greeted by a library of books for the taking, all written by female authors, a partnership with UrbanStems to give women their flowers (literally), an agenda filled with powerful speakers and lots more.

One of the highlights was the “Advancing Healthcare for Women” panel, where experts came together to discuss the power of community, accessibility and using technology for good.

Here are our key takeaways:

Use technology and don’t be afraid of it. Our medical system is siloed, but with the support of AI, we can provide more holistic care, treating the entirety of the patient. – Dr. Sharon Malone

Innovation should be synonymous with accessibility. – Erica Taylor, Ph.D.

What Being Single Has Taught Me About Contextual Targeting

Valentine’s Day hits differently when you’re newly single, but hey—heartbreak has a way of teaching some unexpected lessons. My girlfriend recently broke up with me, and let’s just say I’ve had plenty of time to reflect. Here’s what being single has taught this CPer about contextual targeting.

❤️‍🩹 It’s all about being in the right place at the right time 

Contextual targeting focuses on hitting consumers at a time when they’re primed to receive your message. When approaching a girl you’ve never spoken to before, you want to make sure the time and place are right to make the biggest impact.

❤️‍🩹 Sometimes audiences are hard to reach, but understanding their habits makes it easier to get your message across 

Reaching niche audiences can be very difficult, but contextual targeting allows you to place your brand around the content that this audience would be consuming. Similarly, when you have a very specific type of girl in mind, understanding what they like can make it much easier to create a connection.

❤️‍🩹 Sharing cookies used to be the way to get to someone, but with more focus on consumer privacy, we need to look to alternative options 

With cookies eventually being sunset due to consumer privacy restrictions, advertisers have utilized contextual targeting to reach their audience. Nowadays, there is a much greater emphasis on safety around strangers. Buying a drink for someone (the human equivalent of sharing cookies) might not be the way to approach a girl.

❤️‍🩹 Surrounding yourself with relevant conversation makes the connection stronger and more authentic

When using contextual targeting, your ads will always show up around relevant content. When looking for someone to approach for a conversation, it will always be easier if you have similar interests to focus the conversation around.

❤️‍🩹 Keywords can often mean different things to different people 

Contextual targeting allows you to show up around keywords that otherwise might show up on a blocklist. For example, the word “shooting” might appear on a traditional blocklist, but for a brand looking to advertise around basketball content, it takes on an entirely different, brand-safe meaning. Similarly, an ex-girlfriend might have enjoyed being called “honey,” but this won’t be the case with everyone you meet.

Love at First Sight: Inspiring Generosity Through the Gift of Vision

We teamed up with global nonprofit Seva Canada to showcase the transformative power of sight restoration – crafting an acquisition strategy and campaign to attract new donors.

Together, we launched the “Love at First Sight” campaign, featuring beautiful photography captured by Nepali eye patients. The images told the powerful stories of the people and moments they had missed most—now brought into clear focus following eye treatments, including cataract surgery and glasses.

Bringing the campaign to life: We equipped Nepali eye patients with cameras after their sight was restored. They received training on how to use the cameras and documented heartfelt glimpses of their world—families, friends, pets, homes, and even birds soaring through the sky.

Forging an emotional bond with our audience, the campaign drove a 55% year-over-year increase in new donors.

Even amidst the challenges posed by the Canada Post strike during the critical holiday giving season, the campaign achieved remarkable success.

The Seva Canada business was won via our Vancouver office and supported by a global creative team to bring the campaign to life.
