To be totally honest, I didn’t actually check and just assumed. However, my read of the style guides is that you don’t capitalise the second word in hyphenated titles if there’s a prefix (source).
That seems unusual to me but fair enough—however in this case we’re talking about a proper noun (the name of an organisation), not a common noun that happens to be in a title/heading (e.g. ‘Non-trivial Efforts to Improve the Future are Possible’).
