Anecdotally, I did.
At least, I am no longer buying 400L of oil for my furnace every month, and our cars are cheap(ish) EVs.
So at least for direct oil usage I went to zero.
Today everyone get's a car. Some might be EVs (fueled by coal power) but others are not.
And every year world CO2e emissions go up.
And every day we pretend it's ok because it went up by less that it would have if we had put it up even more. But we need them to come down, not just go up less quickly. And we needed that in 2000. Not "we might manage it in 2030".
I would also look at both the rise of cheap EVs and the size of the ICEs people outside of rich western countries are buying. American SUVs are an outlier caused by heavy subsidies but the cost of buying and operating them is prohibitive in many places, not to mention narrow roads and storage cutting into the appeal. There’s a reason why you see so many cool cars only available outside of the U.S. market and most of them get whole number multiples better mileage than the median American vehicle.
Then we congratulate ourselves.
And I am a doom munger when all I see is hopium.
