Is there a list of companies and the organizations/social policies they support/donate to

I tried looking for a list that named the major retailers/companies and the organizations/social policies/political campaigns they support or give money to. The reason being is it's good for everyone to be aware of so we know where we are putting our money.

I would be greatly surprised if a list like this isn't somewhere on the Internet. Aren't companies required to give this sort of information? And I feel like you guys would be the exact people to ask to find such a list.

Thanks so much for the help!
