About this charity

Hear directly from ACE about its three main programs:

To achieve ACE’s mission of finding and promoting the most effective ways to help animals, we pursue three main programs: Research and Evaluation, Education and Outreach, and Fundraising and Grant-making.

Research and evaluation: Annually, ACE evaluates international animal charities in order to determine their effectiveness at reducing animal suffering. Our comprehensive evaluations process provides an in-depth look at each charity’s programs, track record, strategy, leadership, and culture in order to recommend them as either Top Charities or Standout Charities. Outside of our annual charity evaluation activities, we maintain a robust research program devoted to resolving uncertainties relevant to our work and to the animal advocacy movement as a whole.

Education and outreach: Through online and offline efforts, ACE educates people on how they can help the greatest number of animals. We produce informational videos aimed at explaining the concepts of effective animal advocacy to a broad audience. Our annual Guide to Effective Giving educates donors and advocates about where to invest their resources in order to help the most animals. Our internationally-based team speaks at conferences around the globe to share our work and reach more people interested in reducing animal suffering. We also support those working in the animal advocacy movement by publishing guidance, interviewing leaders and experts, and sharing advice on successful nonprofit practices and operations in order to increase effectiveness.

Fundraising and grant making: Since 2014, ACE has influenced more than $37 million USD in donations within the animal advocacy movement. We offer convenient giving opportunities, such as our Recommended Charity Fund and Movement Grants, for donors to support effective charities and promising projects working around the globe to reduce animal suffering. ACE is also committed to supporting quality research by awarding research grants through our Animal Advocacy Research Fund.
