How To Get A GDP Breakdown For Sub-industries?

Hi guys,

I need for a project to get the data of the GDP of countries by sub-industries and the best would be to have it breakdown using the Global Industry Classification Standard (or an other advanced standard that shows sub-industries).

I wasn’t able to found data that was that much precise (most GDP by sectors or some big sectors by not going into industries & sub). So maybe the data needed is on a special website that I don’t know or is hardly accessible by a simple Google search.

Thanks for any response / upvote / help.
