AI's Unseen Emissions: Marketers Acknowledge Impact, Lag on Measurement

A new survey from sustainability consultancy 51toCarbonZero indicates that while a majority of marketers acknowledge artificial intelligence is increasing carbon emissions, only 36% are actively tracking their full environmental footprint. The findings, released in late July 2026, highlight a significant disconnect between awareness and action within the industry regarding AI's energy demands.

The rapid adoption of AI across creative generation, media optimization, and data processing consumes substantial computational power. This power translates directly into energy usage and, consequently, carbon emissions from data centers. For brands increasingly scrutinized on their environmental, social, and governance (ESG) performance, this unmeasured impact represents a growing reputational risk and a blind spot in their sustainability reporting.

The Unmeasured Footprint

The core issue is a lack of standardized methodology and tools for measuring the specific carbon cost of AI marketing operations. Unlike broader Scope 1 or Scope 2 emissions, calculating the granular impact of a generative AI campaign or a programmatic bidding algorithm requires specific data from cloud providers and adtech vendors, which is often not readily available or transparent. Marketers are left to estimate or ignore, rather than precisely account for, these digital externalities.

This mirrors earlier challenges in measuring the environmental impact of digital advertising more broadly, where ad delivery and data transfer also contribute to energy consumption. However, AI's intensive processing requirements amplify this concern significantly. As AI becomes more integral to campaign execution, the industry faces pressure to develop metrics beyond traditional media KPIs to include environmental ones.

"While the lion’s share of marketers surveyed by 51toCarbonZero believe AI is increasing emissions, just 36% are tracking their full impact."

The onus will increasingly fall on adtech platforms and agencies to provide clearer data on the energy consumption of their AI models and services. Without this, brands risk accusations of greenwashing or, at best, incomplete sustainability disclosures. The expectation for transparent reporting on digital carbon footprints is likely to grow from consumers and regulators alike, pushing marketers to find ways to quantify what is currently an invisible cost.

What comes next

The industry is still in nascent stages of developing robust frameworks for AI carbon accounting. This will require collaboration between adtech vendors, cloud providers, and sustainability experts to establish common standards and reporting mechanisms. Marketers will need to integrate these new metrics into their planning and media buying processes, potentially favoring AI solutions that demonstrate lower environmental impact.

This shift will necessitate new conversations with adtech partners about their infrastructure and energy sources. For agencies, it presents an opportunity to develop consulting services around AI sustainability, helping clients navigate this complex reporting landscape. The future of responsible marketing will demand not just effective campaigns, but also ecologically mindful ones.
