View a list of the charities we examined during our recommendation process. Each charity is categorized by the type of advocacy they do as well as by their recommendation status. Read our reviews, and see the small number of highly recommended organizations available to donors who are seeking to make the greatest impact with their donations.
Recommending effective animal charities is one of our highest priorities. We conduct brief evaluations of many organizations to identify the most promising candidates, then research those organizations' methods and achievements in greater depth. While success is defined partly by the organization under consideration, ACE's evaluations always consider the effectiveness of an organization from the perspective of reducing the largest amount of suffering.
ACE has conversations with leaders in the effective altruism and animal advocacy movements to better understand how we can improve our efforts and to help evaluate how other groups are faring.
We maintain a listing of all reviews from previous rounds of recommendations. Whenever we update a charity review, the old versions will appear in this archive.
