Animal Charity Evaluators (ACE) uses evidence and reason to serve people who want to help animals. Trillions of animals experience extensive but avoidable suffering on farms and in the wild, which motivates our team to contribute to a world where all animals can flourish regardless of their species. We work toward this by identifying where donations can best help animals and awarding grants to promising projects that help animals around the globe.
Hey Ula, great question! This year we conducted an influenced-giving analysis to assess ACE’s counterfactual impact on funding via our Charity Evaluations and Movement Grants programs. We aim to publish the full reports on November 29th.
During our last fiscal year (April 2023-March 2024) the total reported ACE-influenced donations to the charities recommended during that time was $8.5 million, and we estimate that $3.7 million of this would not have been donated if not for ACE’s influence. The upcoming report will thoroughly explain how this was calculated.
Our charity recommendations last for two years. We don’t guarantee that any charity is re-evaluated or re-recommended, so charities know to prepare for that when their two-year recommendation cycle ends. For some charities, being recommended by ACE might be their first introduction to certain donors. Anecdotally we’ve also found that some donors choose to continue donating to formerly recommended charities.
We expect that being recommended for the first time, leads to a greater increase in funding than retaining a recommendation. The same seems likely for a recommendation for a newer intervention or animal group, or for a younger charity compared to the budget impact of a recommendation for a well-known charity. According to a recent survey, ACE’s annual influence per charity has varied anywhere from about $150,000 to $1,000,000+. Some of those gifts might not be fully counterfactual (this will also be further explained in the report coming out next week). Assessing budget impact and change in recommendation status is something we need to examine further though, so we’ll be expanding our impact assessment work this year to include more than just our quantitative counterfactual impact on funding.
Considering each of our Recommended Charities have significant room for more funding, we suggest donating to our Recommended Charity Fund because these gifts are currently being matched. Donations will help all 11 of our Recommended Charities that we estimate will have an exceptional impact for animals with additional donations.

Thanks Steven, great question! In short: yes we do, and no there isn’t :-) We think GiveWell’s approach of using GiveDirectly as a benchmark makes sense for GiveWell, and we’ve had several team discussions about whether we could take a similar approach. One step in this direction is to seek to get to the same unit of animals helped/suffering averted for each charity to make it easier to compare across charities, and we’ve sought to do that this year through our use of AIM’s Suffering-Adjusted Days (SADs) model. (You can read more about our 2024 cost-effectiveness assessments here.) However, while we found this helpful for this year’s Evaluations, it’s not always possible to reach a meaningful SADs estimate given limitations such as the long-term or speculative nature of some charities’ programs, a lack of reliable data around charities’ achievements, a lack of evidence on the relative cost-effectiveness of different animal advocacy interventions, and the diverse range of programs conducted by the charities we evaluate. We’re also not aware of any charities in the animal advocacy space that share GiveDirectly’s room for additional funding and potential for scaleability.
Instead, we currently base our recommendation decisions on a set of decision guidelines that align with our evaluation criteria (see here for the guidelines and additional context), and use these to score charities against one another. It’s possible that in future a sufficiently scalable charity will emerge, and the animal advocacy movement will have sufficient evidence and data for us to produce reliable cost-effectiveness assessments for all the charities we evaluate, but at the moment this doesn’t seem realistic.
Currently, our Recommended Charities are those we’ve identified as the most impactful giving opportunities for animals based on the information we have available. Considering each of our Recommended Charities have significant room for more funding, for those looking for impactful donation opportunities, we suggest donating to our Recommended Charity Fund that supports all 11 of our Recommended Charities and where gifts are currently being matched.

That’s a great question and one that we spent a lot of time considering in this year’s round of evaluations. We aimed to use SADs in all cost-effectiveness analyses and attempted to find a way to quantify each charity’s impact using the SADs unit. We have found that for more indirect work, such as GFF’s programs, quantifying the number of animals affected is largely speculative and requires a number of assumptions. For these cases, we decided to not make the assumptions needed to estimate the SADs averted but to stop at an intermediate unit in the analysis. For GFF, this was the number of people reached through their programs per dollar. Our reasoning for avoiding highly speculative assumptions is based on one of our guiding principles, which is to follow a rigorous process and use logical reasoning and evidence to make decisions. For cases like GFF, we focused more on their Theory of Change analysis to guide our decision-making. We are excited about their work because China farms around 50% of the world’s farmed animals, and GFF has made inroads with getting animal welfare on the government’s agenda, which could have significant expected value in the long term (although we didn’t model this explicitly).
Overall, we believe that interventions with a long theory of change (such as some policy interventions) and meta-interventions are often too speculative to estimate the number of animals affected and therefore the SADs averted. This appears to be consistent with the existing research in the animal advocacy movement, where the existing cost-effectiveness estimates focus on direct interventions (corporate campaigns, institutional outreach) and avoid quantifying indirect interventions (research, movement building). We will review our methods in the coming months and will reconsider how we compare charities that do more indirect work.

Thank you for your question. We refine our methods each year and we don’t think that recent changes mean that we can no longer rely on the decisions we made in 2023.
Specifically about cost-effectiveness, in the past ACE has identified limitations of direct cost-effectiveness analyses and found it less helpful to directly estimate the number of animals helped per dollar. Instead, we began exploring ways to model cost-effectiveness, such as achievement scores and the Impact Potential criterion. Since then, the animal advocacy movement (namely Welfare Footprint Project, Ambitious Impact, and Rethink Priorities) has invested in research that enables quantifying animal suffering averted per dollar and in turn, we’ve evolved our methods. However, we think it is still remarkably challenging to do these calculations and draw conclusions from them, and that using proxies is still a reasonable approach.
Additionally, while we’ve introduced a theory of change criterion to formalize our assessment of charities’ assumptions, limitations, and risks, we have already been taking these factors into account during our decision-making in the past. Our other two criteria, room for more funding and organizational health, were included in our methods in both years.
In summary, while we see recent improvements as a step forward, we wouldn’t claim that 2023 charities were evaluated with a less rigorous methodology.

Hi, great (and topical) question! Yes, some ACE staff use generative AI models such as ChatGPT and Claude to help generate ideas or to help draft lower-priority internal documents. However, we don’t use such models for external or high-priority documents given the various limitations of AI models (such as the risk of factual errors, biases, and plagiarism), and we also don’t input information that could be potentially sensitive.
We apply a similar principle to image generation models. Given the risk of AI-generated images being seen as misleading in certain contexts, potentially casting doubt on, e.g.. photographic evidence of farm investigations, we instead use images from public-domain sources, prioritizing ethically aligned sources such as We Animals Media.
Personally, the most useful AI tool in my day-to-day work is Perplexity, which cites its responses and can be really helpful for locating research papers. I also find ChatGPT and Claude helpful for summarizing research, cleaning up documents, and advising on spreadsheet formulas. A newer tool is Google’s NotebookLM, which seems very useful for distilling information from a wide range of sources.
For more information you can check out ACE’s Responsible AI Usage policy. We also have an internal document where staff share AI use cases with one another, so you could consider introducing something similar at your own organization if that sounds helpful!

Thanks for your questions! This year we decided to use Ambitious Impact’s new unit SADs (Suffering Adjusted Days) in our cost-effectiveness analysis. This allowed us to provide the estimate in a unit that could directly compare the suffering across different interventions and animal species. For example, we could compare in the same unit the welfare improvement of cage-free campaigns, crate-free campaigns, and institutional meat replacement campaigns (see Sinergia’s review). We found SADs especially useful for more direct interventions, where the welfare improvement and the number of animals affected can be quantified with some certainty. Note that because SADs are a recent methodology that hasn’t been finalized yet, we expect that some of the estimates we used might change. Although we found SADs very useful in our cost-effectiveness analysis, we plan to discuss in our coming strategic sessions whether we will keep using this methodology in our evaluations, and for which interventions it might be more or less suitable. Depending on our strategic priorities and capacity, we will consider refining and updating the current estimates, as well as producing estimates for more interventions and species.

Thanks for the question! None of our current Recommended Charities work on cultivated protein sources, though we have previously recommended charities working on this (such as Good Food Institute and New Harvest) and awarded Movement Grants to projects in this area (such as Cellular Agriculture Australia). We’d certainly be open to considering charities and Movement Grant applicants working on this in the future.
— Max
At ACE we currently prioritize farmed and wild animals, so none of our Recommended Charities work to reduce the use of animals for scientific purposes (i.e. research, testing, and science education).
If you’re interested in organizations and institutions that are focused on this area, here are few great options to explore:
There are also government-funded alternatives centres around the world like the European Centre for Validation of Alternative Methods (ECVAM).
