AI Videos in EcoLogits

We are happy to release our first methodology for assessing the environmental footprint of AI-generated videos. This is a major step forward in modeling new GenAI use cases beyond text generation, and this contribution is part of the work pursued with the GenAI footprint Alliance.

The GenAI footprint Alliance is a Publicis Groupe initiative dedicated to the common good. Its goal is to quantify and share reliable data on the environmental footprint of GenAI models for content production, and to integrate this data into open source tools. The alliance is led by Publicis France's CSR team, AXA, Engie, and Groupe La Poste/La Banque Postale as founding members, with support from FDJ United, Accor, L'Oréal, Orange, and Renault Group as partner members.

The research behind this work was conducted by the Sustainable AI Group (SAIG) with Sasha Luccioni, Boris Gamazaychikov, and Nidhal Jegham. The methodology was then operationalized in a corporate context through its integration into EcoLogits tools from CodeCarbon and the e-footprint modeling tool, developed by Publicis Sapient France and open-sourced within Boavizta.

The GenAI footprint Alliance also contributes to the Consortium IA durable supported by ADEME. The Consortium IA durable gathers Institut Louis Bachelier and CodeCarbon.

Why AI videos?

AI video-generation models are widely recognized as energy intensive. Academic work has discussed this growing concern, and recent studies on text-to-video systems show that video generation can be far more power-hungry than other modalities such as text or image generation, especially as duration and resolution increase (Delavande, Pierrard, and Luccioni, 2025). The discontinuation of OpenAI's Sora app in 2026 also highlighted the operational and economic challenges associated with scaling AI video generation.

At the same time, AI videos are now used across many industries, from social media content and professional film editing to customized online advertising. Models can generate longer videos, include audio tracks, and support high resolutions up to 4K, making them increasingly practical and versatile.

This growing diversity of use cases, combined with the environmental impact of each generated video, makes AI video generation highly relevant to address in EcoLogits today.

One key learning from this work is simple: the more you ask, the greater the environmental impacts. This depends not only on the number of videos generated, but also on the size of the model, the duration of the video, and the selected resolution.

How do we estimate these impacts?

The environmental impacts are estimated using a bottom-up methodology, similar to the one we have already published and continue to maintain for text generation. A core part of the method is estimating the direct electricity consumption of the servers and infrastructure that support AI video models.

This is where SAIG's work is being integrated into EcoLogits. They developed benchmarks of open models to understand how generation latency for a single video can be estimated from the requested duration and resolution, as well as the model and infrastructure provider. Their academic paper is still under preparation and will be available soon.

From the estimated electricity consumption and hardware use, we then deduce environmental impacts using a life cycle assessment approach. EcoLogits models provider data-center overhead and locations to estimate greenhouse gas emissions and water consumption during the use phase. It also accounts for hardware manufacturing impacts, reusing work from Boavizta, Hubblo, and academic research on AI hardware life-cycle impacts (Schneider et al., 2025).

Try it today

Impact estimations for AI videos are now available in all EcoLogits tools:

Try it on your own use cases, and feel free to share feedback with us directly on Discord or through our GitHub repositories.

You can also try these estimations in the e-footprint tool, which integrates the latest version of EcoLogits. It lets you model more complex usage patterns, create your own scenarios, and explore how different choices increase or reduce environmental impacts.

Improvements in generation latency estimation

We have made an improvement regarding how we estimate the generation latency (i.e. estimated duration of a request excluding network latency) for a request. Our new default estimation is based on time to first token and throughput metrics collected on OpenRouter for the supporter providers and models.

The new generation latency calculation is now:

\[ \text{generation latency} = \text{time to first token} + \frac{\text{output tokens}}{\text{throughput}} \]

With:

  • Time-to-first-token (TTFT) represents the average duration in seconds of the pre-fill phase for an LLM.
  • Throughput (TPS) represents the average number of output tokens generated per second, it helps estimate the duration of the decode phase for an LLM.

These two metrics are being collected from OpenRouter, a service that centralizes the access to many AI providers with a single API key. Since the service is widely adopted (over 30 trillion tokens per month) the average data should be representative of real-world conditions.

This work extends what was previously done to patch the energy and impacts overestimations we had in EcoLogits Calculator compared to the Python library. Having this new estimation method in our core methodology makes it more reliable and reusable in all projects that depend on EcoLogits.

It is important to note that the old method to estimate generation latency using the ML.ENERGY Leaderboard is still being used when TTFT and TPS values are not available on OpenRouter. This is the case for the Hugging Face inference provider that we support.

EcoLogits and CodeCarbon are joining forces

The year 2025 was a milestone for EcoLogits. We saw growing adoption, formed new partnerships, and made significant methodological progress. More organizations than ever are now using EcoLogits to estimate and reduce the environmental footprint of generative AI.

Today we are pleased to announce a major step forward: EcoLogits is joining the CodeCarbon non-profit. This collaboration unites two complementary initiatives, driven by a shared commitment to scientific excellence. Together, we aim to make environmental impact assessment for AI more accessible, transparent, and effective by building open source tools that are robust and widely trusted.

This alliance expands our technical and partnership capabilities, strengthens our methodological expertise, and increases our collective impact on the responsible digital ecosystem.
