Just a word of caution about web directories. There are dozens of Irish web directories claiming to be ‘the’ green directory. Also several other directories claiming that there list is 'the most comprehensive'.
The problem is that the prices to be listed vary from FREE to several hundreds of Euro per Year! So one cannot be listed in them all.
The online Golden pages.ie might not be the best but at least you know that the business has a phone number and an address.
Anyway Happy New Year!
