Who should act, when, and how to reduce risks from AI? A database of over 2200 mitigations of AI risks, categorized by five taxonomies
There are many ways to reduce AI risks, from changing how AI systems are built to helping society adapt. But how do we make sense of so many mitigations? Who should carry them out, and when? To answer these questions, we built the AI Risk Mitigation Repository, described below:
The AI Risk Mitigation Repository and Taxonomy turns a long list of ideas into clearer next steps: who should act, when, against which risks, and how. It is part of the MIT AI Risk Initiative, which aims to increase awareness and adoption of best practices to address AI risks across the ecosystem.
There are several ways to use the AI Risk Mitigation Repository:
The repository is free to view and use. You can browse all 2,206 mitigations in our interactive data explorer, where you can filter and compare them by any of the five taxonomies and by source document, or download the full dataset as an Excel file (0.8 MB) to use in your own analysis.
The data is licensed under CC BY 4.0, so you can reuse and adapt it with attribution. If you build something with the repository, we'd love to hear about it.
We carried out a systematic review following a published protocol and PRISMA reporting standards. We searched academic and grey literature databases (Scopus, arXiv and Crossref), screening over 12,000 records, and asked 104 experts in AI risk to suggest additional documents, who nominated 90 more. From these we included 47 frameworks, taxonomies and structured lists of AI risk mitigations, and extracted 2,206 individual mitigations into the repository.
We developed the AI Risk Mitigation Taxonomy by iteratively grouping the extracted mitigations and revising the categories based on feedback from 45 experts. Each mitigation was then classified against this new taxonomy, along with four existing taxonomies, using LLM-assisted coding, which we checked against human reviewers. Full details are in the paper.
We included 47 documents published between 2018 and 2026, about half of them in 2025. They come from academic researchers, government and public bodies, non-profit research institutes, industry and standards organizations, and include examples such as the International AI Safety Report, the NIST AI Risk Management Framework's Generative AI Profile, and the EU General-Purpose AI Code of Practice.
To be included, a document had to propose a structured list or framework of AI risk mitigations that applies across sectors. We excluded documents focused on a single sector, a single type of AI system, or a single risk. The full set of inclusion criteria can be found in the paper.
The repository shows how mitigations are proposed in the literature, not which ones organizations actually use or how effective they are. It doesn't cover every law, standard or software toolkit, and some documents contributed many more mitigations than others: the five largest supplied 39% of all records. Around half the documents (23 of 47) were themselves reviews, so some mitigations may be counted more than once.
Classifying mitigations also involves judgement. Many are described vaguely or as goals rather than actions, and agreement between reviewers varied across the five taxonomies. The taxonomy trades some nuance and depth for clarity and accessibility. It doesn't yet capture feasibility, effectiveness, or how mitigations depend on each other. We expect it to evolve as the field develops, and we welcome feedback.
