Who published green data book?

The term "Green Data Book" isn't a universally recognized or standard title for any specific publication. To help you find what you're looking for, could you provide more information?

For example:

* What is the subject matter of the book? Is it about environmental data, environmental policies, green technology, or something else?

* What year was the book published?

* Do you have any other details about the book? (For example, the author, publisher, or specific topic covered)

With more information, I can try to identify the specific publication you're asking about.
