Let's look at me: I don't own a car, live in a smaller town, move around mostly on foot, take public transportation, long distance mostly train. I have two kids and for years my electricity total was 1500kwh a year. Last year it was 1100kwh (heating is gas though, that's what my building has). All this and I do cook a lot with an electric stove. I bought some new appliances before the old ones were completely broken (although they were close) partly because the new ones were all very energy efficient.
But: I live abroad and take my kids to my parents once a year, and fly. Last year I flew four times, including intercontinental (albeit a true outlier of a year). I consume things produced all around the globe, either as items like phones, or food, and the food I do probably daily (I really like fruit, so bananas, mangos, avocados etc).
My point is: my carbon footprint is pretty low, and I try to be mindful about not wasting resources. And it's not that hard, I don't feel like I am missing out on something if I don't drive a car. But I still took my kids to Spain on a vacation, and we still flew there to sit on the beach. Giving that up is hard, and making them sacrifice their childhood fun is hard.
There's a range of what people are ready to give up. I would say I'm on the better side of it, but it's still not enough. Almost no one is ready to sacrifice, and we need almost everyone to sacrifice. Governments do lip service to these goals, but let's see how much countries like Spain sre ready to curb tourism, or countries like Germany and China that live off manufacturing to cut consumption. Who will give up their job to reduce carbon emissions?
The saying train wreck in slow motion has merit.
