This seems like a useful fundraising tool to target people who are unwilling to give their money to wherever it will do the most good, but I think it should be flagged that if a person is willing to donate their money to wherever it will do the most good then they should do that rather than donate to the best animal giving opportunities for the purpose of ethical offsetting. See Ethical offsetting is antithetical to EA.
