You can create a site global lookup column by creating a site column at the root of the site collection. Point the lookup column to a list in the root site of the site collection, and all children sites can now use the site column looking up the root list.
This can also be used further down in the hierarchy; if you create a site column at one level in the hierarchy, all children sites also have access to that site column.
