An Oxford-based charitable organisation that aims to change the world’s giving culture and encourages members to donate 10% of their lifetime income has now received pledges of more than $2.5 billion. The charity is guided by principles of effective altruism, using reason and evidence to find the best opportunities to do good. Julian adds: 'Ultimately, we want to change the world’s giving culture, so that giving effectively and significantly is the norm. We're very interested in reaching first-time donors and providing them with support so they can begin their journey of effective giving. We offer a wide variety of resources for these sorts of individuals, including cause area write-ups, charity recommendations, an effective giving guide, member profiles, events, and plenty of other material that can help make them more effective givers.'
