Check out the EPA’s stats on ghg emissions at this LINK. 28% of emissions total are from non-agriculture/shipping transportation, and if you break that down then 57% of the 28% are light duty vehicles, all larger road vehicles are 23%, and aircraft are 9%.

Since 2005 emissions carbon-equivalent total of the USA has fallen about a billion metric tons thanks to awareness and federal programs to reduce and eliminate emissions, almost exclusively in the Electrical Power sector.

So even if you cut out all consumer non-business transport you’re left with 72% of emissions. A person who votes to curttail polution does more good than a person who drives a hybrid.
