> Hardly anything the IPCC says seems to translate into policy.
Following their reports multiple countries have adopted measures directly citing those reports, with targets based on those reports. E.g. to maintain warming below X C, we'll have to reduce by Y our annual CO2 emissions, so we'll ban new internal combustion engine cars sales starting 20ZZ, while also doing this and that.
Sure, where Y is either woefully inadequate or never hit and ZZ is typically far enough in the future that it's too late to have a meaningful effect, and can be reversed anyway before it comes to fruition. The likelihood that "eat less meat" is going to make it into meaningful policy changes seems pretty low.
