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.

Mission and Vision

Our mission is to find and promote the most effective ways to help animals. Ultimately, our vision is a world in which no individual is given less than full moral consideration on the basis of any morally irrelevant feature of their identity, including species membership.

Charity Evaluations

We conduct charity evaluations to identify the organizations that will likely make the most significant difference for animals. We publish a list of recommended charities to promote organizations that can do the most good for animals with additional donations. We are transparent about our evaluation methods and processes and actively improve them each year.

We award grants through our Recommended Charity Fund and Movement Grants programs. The Recommended Charity Fund supports proven high-impact charities that help reduce animal suffering. Our Movement Grants program supports organizations or individuals that work in high-priority regions, use novel approaches, or focus on underrepresented animals. Together, these programs help build and strengthen the global animal advocacy movement.
