Capital one converted the points/miles into cash and donated it to a relief agency for Haiti. Delta does not have a lot of details on their donation of skymiles.

They list major American Charities who do have oversight. I have no knowledge other than what you can find on the internet. In the past I have donated miles on other airlines to organizations that help US military personal fly home.
Other points for Japan.
