World GDP is about $87.25 trillion and California GDP is about $2 trillion, so California has more than 2% of world GDP. You could make the case that that's a more important metric than population.
Is that real, or a side effect of the number of companies which are basically ghost-chartered in Delaware?
> Delaware does have a higher CO2 emission rate per capita, tho (nearly 50% more than California)
I wonder how much of that is due to increased heating necessary during winter...
