The start of a new year is a great time to set meaningful goals, and making sustainability one of them is a smart choice.
Advertising technology continues to grow at an incredible pace, but so does its environmental footprint. In 2025, we saw major progress. According to IAB Europe, 74% of companies now view sustainability as a core business priority, and nearly half are actively measuring the carbon footprint of their digital media. That’s double the figure from 2024! It’s a big step forward, but challenges remain. Common standards and education are still lacking.
The rapid adoption of AI in adtech has amplified the conversation around sustainability. While AI brings precision and automation, it also increases computing load and energy use. This makes carbon footprint tracking and emissions reduction more critical than ever.
Why Sustainability in Adtech Matters More Than Ever
Three developments made 2025 a turning point:
Standardized measurement is here. Ad Net Zero and the WFA’s Global Alliance for Responsible Media introduced and updated the Global Media Sustainability Framework (GMSF). This framework provides voluntary standards for calculating and reporting greenhouse gas emissions across six media channels: digital, TV, out-of-home, print, audio, and cinema. The June 2025 update operationalized digital formulas and aligned with global protocols, making it easier for brands to include media emissions in Scope 3 reporting.
Emission transparency is scaling in programmatic. Data providers and platforms are integrating emissions into planning and buying. Scope3 expanded access to GMSF categories, and partnerships in 2025 embedded carbon tracking into creative and media workflows. Sustainability is moving from after-the-fact reporting to proactive decision-making.
Simple actions make a big difference. Compressing video files, reducing non-viewable impressions, and cutting low-quality placements are proving that lower carbon doesn’t mean lower performance.
The industry finally has the tools and standards to act. Now it’s about using them.
Our Mission
Neuwo’s mission is simple: make context work harder for performance, privacy, and sustainability. By helping clients activate contextual intelligence instead of ID-heavy strategies, we reduce unnecessary data movement and improve relevance.
The biggest drivers of emissions in adtech are well known: heavy data transfers, inefficient supply paths, and wasted impressions. Practical steps like compressing video files, reducing bid duplication, and prioritizing quality inventory can make a measurable difference. Contextual targeting is emerging as a powerful sustainability lever. By reducing reliance on identity graphs and minimizing unnecessary data movement, context helps cut waste while improving relevance.
For advertisers, agencies, publishers, and platforms, sustainability isn’t just a compliance checkbox, it’s becoming a competitive advantage. Brands want greener campaigns. Agencies need frameworks to deliver them. Publishers and SSPs are under pressure to optimize infrastructure and prove their role in a low-carbon supply chain.
How Neuwo Fits In
At Neuwo, we believe context can do more than drive performance; it can drive sustainability. Our APIs and audience solutions are designed to cut unnecessary data movement and deliver more relevant placements, helping advertisers follow best practices that reduce emissions and fit with industry sustainability standards such as the “Global Media Sustainability Framework.”
For advertisers and brands, this also means adding brand safety signals to ensure campaigns run in suitable environments without over-blocking, which reduces waste and improves efficiency.
More to add, our technology is built with sustainability in mind. Neuwo’s models are trained on LUMI, one of the most energy efficient supercomputers in the world. LUMI is powered by renewable energy and uses advanced heat recovery systems to warm local communities, making it a benchmark for green computing. Every contextual decision we deliver is backed by infrastructure designed to minimize environmental impact.
If you’re ready to make your advertising greener without compromising performance or safety, our team is here to help turn that goal into reality.
