Animal Charity Evaluators

Animal Charity Evaluators (ACE), formerly known as Effective Animal Activism (EAA), is a US-based charity evaluator and effective altruism-focused nonprofit founded in 2012. ACE evaluates animal charities and compares the effectiveness of their different campaigns and strategies. The organization makes charity recommendations to donors once a year. Its stated purpose is finding and promoting the most effective ways to help animals.

History
Animal Charity Evaluators was formed in 2012 as Effective Animal Activism, a division of 80,000 Hours, by the Centre for Effective Altruism. It rebranded as Animal Charity Evaluators (ACE) in 2013. Australian philosopher Peter Singer sits on the organization's advisory board.

Since its inception, ACE annually published recommendations for charities to donate to based on their impact and effectiveness, under two categories: "top" and "standout". When it published its 2023 recommendations, it moved away from these categories, instead moving to only "recommended" charities. This was intended to more fairly represent the charities present and better support the animal advocacy movement.

Recommendations
ACE publishes its recommended charities once a year in November, ahead of Giving Tuesday. In 2023, ACE's recommended charities were Faunalytics, Legal Impact for Chickens, New Roots Institute (formerly known as the Factory Farming Awareness Coalition), Shrimp Welfare Project, The Humane League and Wild Animal Initiative.

In 2022, ACE recommended Çiftlik Hayvanlarını Koruma Derneği, Dansk Vegetarisk Forening, Fish Welfare Initiative, the Good Food Institute and Sinergia Animal.

Reception
Marc Gunther reviewed ACE in a 2015 article for Nonprofit Chronicles, stating: "[T]he work of Animal Charity Evaluators (ACE) is relevant to nonprofits of all kinds. As its name suggests and, on a very modest budget, ACE evaluates animal charities. Its work could inspire those who want to evaluate charities in other sectors—education, the environment, that arts, whatever." He further noted: "The point is, Animal Charity Evaluators is asking the right questions–the kind all nonprofits should be asking themselves."

Peter Singer mentions ACE's work in his 2015 book The Most Good You Can Do and in an online article for Salon. He describes their recommendations as a form of "altruistic arbitrage", picking the low-hanging fruits of animal activism, which he describes as worth supporting.

In 2017, Harrison Nathan and the animal rights group SHARK criticised ACE, suggesting they were biased in favour of charities associated with one charity founder, Nick Cooney. Nathan and ACE engaged in an exchange of open letters and responses.
