I'd guess transportation plays a bigger role, but not sure.

US emissions are ~29% transportation and ~27% electricty generation [1]. The US uses ~13x as much oil [2].

Natural Gas isn't particularly dirty. Coal and petroleum only make up 24% of power generation in the US [3]. Fossil fuels make up ~9% of electricity production in France [4].

>Natural Gas isn't particularly dirty

Just a small nit but the OP was referencing CO2. Natural gas is cleaner than other fossil fuels. “Clean” != low carbon (although it’s lower than other fossil fuels)
