One for the World is an organization that uses rigorous, data-driven charity selection to recommend the most effective charities to donate your dollars to. By giving at least 1% of your income to these effective charities, you can maximize your impact and fight extreme poverty.


Our Beginning

One for the World began at the Wharton School in 2014 when Kate Epstein and Josh McCann started a conversation about how MBA students could make a huge positive impact by giving to effective charities. Many students and young professionals want to make charitable giving a part of their everyday lives, but don't know which charities to give to, or don't have the time to research charities in detail. One for the World strives to make that decision easier.


Since 2014, One for the World has grown to over 300 members, building a movement across six schools. Together, we have donated $161,535 to effective charities since 2014, and are on course to donate $150,000 in 2018 academic year (July 1 to June 30) alone.

"One for the World is a small, but very important development in the fight against the devastating effects of extreme poverty."

— Charlie Bresler, Ph.D, Executive Director, The Life You Can Save


Our Mission

One for the World seeks to grow the effective altruism movement. We critically assess which charities are having the most impact, because the charities that you donate to are going to be the biggest factor in determining how much good you can do. We make donating to these effective charities easy by providing a list of recommended and vetted charities that you can trust. By focusing giving only to the best organizations, you can have an impact even with a small donation.

One for the World has partnered with The Life You Can Save to compile a list of recommended charities based on extensive research and analysis. One for the World’s portfolio consists of 20 highly effective charities, of which we have designated five as One for the World Top Picks.
