We support each other in our commitments to helping others and learning about effective giving. We aim to create a culture where people are inspired to give more, and give more effectively. We believe that charitable donations can do an astonishing amount of good. However, the impact can vary wildly depending on where we donate. Because the difference between charities is astounding, it is important that we donate to the most effective charities if we want to have a significant impact. Giving What We Can was conceived of by Oxford philosopher Toby Ord. He was inspired by the ideas of ethicists such as Peter Singer to commit to donating a large proportion of his income to effective charities. In November 2009, Toby and fellow Oxford philosopher Will MacAskill launched Giving What We Can as an international community of people who were committed to giving more, and giving more effectively. Giving What We Can was one of the first in a growing network of like-minded organisations focused on effective altruism, the project of using evidence and reason to figure out how to best contribute to helping others, and taking action on that basis.
