Specifically, 80–90% of Americans underestimate the prevalence of support for major climate change mitigation policies and climate concern. While 66–80% Americans support these policies, Americans estimate the prevalence to only be between 37–43% on average. Thus, supporters of climate policies outnumber opponents two to one, while Americans falsely perceive nearly the opposite to be true.
Yes ultimately these changes need to come from government, but people will throw an actual fit over giving up meat, cars, homes. That popular people's government won't remain popular for long tbh, there would have to be some concessions in other areas to extract these things. My thought is possibly a combination of lab grown meat to replace animal agriculture (this tech is coming, but our government could put more money into R&D for this), giving everyone an appropriate home/apartment/townhouse or whatever is deemed necessary, full employment for people with good paying jobs. People will still get mad as hell about single family homes but idk, there would definitely need to be some give and take
