Sign your Pledge
I hereby recognize that I can use part of my income to do a significant amount of good.
Since I can live well enough on a smaller income, I pledge that from 11 juillet 2024 and for the rest of my life or until the day I retire, I shall give at least 10% of my income to whichever organisations can most effectively use it to improve the lives of others.
I make this pledge freely, openly, and sincerely.
I'm motivated to take this pledge today..

Is a pledge legally binding?No. A pledge is a voluntarily commitment and enforced solely by your own conscience. In some circumstances, it may be best to resign from your pledge by filling in our depledging form.What if I’m not ready to pledge?Set yourself a reminder for later, or get in touch if you’d like to discuss anything! In the meantime we encourage you to donate to an effective charity, browse our resources, sign up to our newsletter, follow us on social media, attend an event, join an effective altruism group.What do you mean by effective charities?Some organisations are especially good at using donations to improve the world. They tend to work on unusually promising interventions, use scientific evidence to plan their activities, and seek out ways to increase their own impact. Our website provides recommendations for specific charities and guidance for doing your own evaluations.
