Every year, Animal Charity Evaluators (ACE) invests several months in evaluating animal advocacy organizations in order to find those that are working effectively and are able to do the most good with additional donations. Our goal is to help people help animals by providing impactful giving opportunities that reduce the most suffering possible. This year, we are excited to announce that we have selected four Top Charities:
We are also pleased to recommend Essere Animali, the Good Food Fund, and Vegetarianos Hoy as new Standout Charities. Additionally, Sinergia Animal and Sociedade Vegetariana Brasileira retained their status as Standout Charities after being re-evaluated this year, and Anima International has been added to our list of Standout Charities.
