Saudi Arabia has had an active delegation at every IPCC meeting over three decades - no excuse to be unaware, they always manage to scrape as close as possible to rejection from the process. By the way we misrepresent by saying "Saudi Arabia" - petro-dollars are only existential for an autocratic government (similar applies to gas-putin) - Arabian population would benefit from less climate change (their region will approach uninhabitable in summer - pity COP was not in July - note how they moved world-cup).
