To ensure that the use and development of AI is in line with planetary boundaries, this inventory of initiatives brings visibility to Green AI collaborative projects that aim to reduce or minimize the environmental impacts of AI.

These projects were selected following consultation with members of the Coalition for Sustainable AI. They are organised into sub-categories according to how they address AI environmental issues.

Standards

Roadmap for AI environmental sustainability standardization

The objective of this roadmap is to ensure efficient use of resources, reduce confusion, promote consistency in the measurement of the environmental impact of Artificial Intelligence (AI), and facilitate the widespread adoption of best practices in that regard. Contributors wish to work towards non-conflictual standards to measure the environmental impact of AI and encourage collaboration between international standardization bodies to avoid, as far as possible, the duplication and overlaps of standards.

Environmental Impacts of Artificial Intelligence Working Group

This standard defines a measurement framework for reporting on environmental indicators for training models and deriving inference on Artificial Intelligence (AI) systems. This includes harmonized measurements of compute intensity (e.g. energy use) with associated environmental impacts (e.g. carbon dioxide (CO2) emissions, or water consumption). This standard describes methodologies to separate the measurement of AI-specific compute (i.e. data centres used for AI training or inference) from general purpose compute (e.g. data centres used for other purposes like cloud services).

Software Carbon Intensity for AI

The purpose of this proposed specification is to assist AI practitioners in understanding and reducing the carbon footprint of AI systems. By making informed choices about model design, computational efficiency, and deployment strategies, practitioners can minimize emissions while maintaining performance. A working group is developing a methodology for calculating the carbon emissions rate (SCI score) of AI software systems, including both classical AI and generative AI applications. This specification aims to provide a reliable, consistent, and comparable measure that practitioners can use to set targets and track progress in reducing carbon emissions throughout the AI lifecycle.

Best practices

Engagement Kit for Frugal AI

The French Ministry of Environment, in partnership with the Hub France IA and AFNOR Standardisation, is publishing and submitting for consultation a list of best practices on frugal AI for public and private stakeholders. Each organisation can adapt this list and cite it in AI charters, such as ethics charters. This list aims to encourage organisations that adopt it, to have a reasoned development of the technology, by questioning the need for AI above all and by promoting efficient AI systems. This list of best practices aims to propose operational and achievable actions.

Measuring & Reporting tools

Code Carbon

CodeCarbon is a lightweight software package that integrates into a Python codebase. It estimates the amount of carbon dioxide (CO2) produced by the cloud or personal computing resources used to execute the code. It then shows developers how they can lessen emissions by optimizing their code or by hosting their cloud infrastructure in geographical regions that use renewable energy sources

Net Carbon Impact Assessment Methodology for ICT Solutions and case Study Calculators

The European Green Digital Coalition developed science-based methods to estimate the net environmental impact of real-life digital solutions across sectors – Energy/Power, Transport, Construction/Buildings, Smart cities, Manufacturing, Agriculture. The main outcomes of the EGDC Phase I were a science-based method to calculate the net climate impact of given solutions, Case Study Calculators, which contributed to refining the Net Carbon Impact Assessment Methodology, and deployment guidelines to provide recommendations for green digital transformation in each of the six sectors.

BoAmps

This project is composed of a standard datamodel (with tools to fill it easily) and an open data space for collecting and sharing energy consumption measures from AI systems. The goal is to shed light on the materiality (hardware and power consumption) induced by the use of AI, with the aim of deducing the environmental impacts associated with their use, with a systemic approach. This database could then be used to convert electricity and resources into a multi-criteria environmental impact, based on user-specific references to enable LCAs to be carried out.

Green Digital Action Working Group on Sustainable AI

The Green Computing pillar of the Green Digital Action (GDA) initiative, under the auspices of the International Telecommunication Union (ITU) together with over 50 partners, has embarked on a comprehensive three-phased project to tackle the challenge of the absence of clear, standardized metrics for measuring AI’s environmental footprint. The first phase involves an overview and meta-analysis of current efforts to measure the environmental impact of AI. In the second phase, the project will develop a comprehensive measurement and testing plan. Finally, the third phase will implement this plan, assessing the environmental impact of various AI scenarios and workloads.

Call to action

Impact AI

This research project examines AI projects oriented towards the public interest with a focus on sustainability and develops a transdisciplinary auditing method to evaluate their contribution to societal transformation and ecological sustainability. The goal is not only to make the social impact of AI systems measurable but also to identify concrete actions for their responsible use. To bridge scientific analysis with practical applicability, the evaluation method developed will be made publicly available. This ensures that both trained experts and organisations can directly foster the auditing method. In this way, Impact AI contributes to strengthening the sustainable use of AI systems and enabling informed decisions for technologies that serve the public interest.
