I would love to get this, but never been able to find something that looks close to accurate. Remember that many countries also have different rules for B2C than for B2B, B2C rules being the most restrictive.
Usually, Germany and The Netherlands are the strictest countries, but I would not recommend to comply with their standards for all countries. For instance, if you move to double opt-in in France, as most of visitors are not used to it, you will end up with very few mailable leads.

Here are links i've collected. I would speak to local counsel and have them review your process chart first. There is no 100% perfect source on this one.
BUT, in general
US = opt out (but I would use double opt in)
ROW = opt in or double opt in
DE = double opt in
Default - use double opt in.
