View a list of the charities we reviewed during our recommendation process. Each charity is categorized by the type of advocacy they do as well as by their recommendation status. Read our animal charity reviews and learn why we believe our recommended animal charities will have the greatest impact on helping animals.
Our goal is to identify the most effective animal charities, not to rate or grade all organizations. Our charity recommendation process involves several sequential stages, with new recommendations being released in November or December each year.
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.
