If there is only one thing you could do to influence climate change caused by the US, it should be lobbying for a gas tax.
In the 70s, Europe chose to reduce oil consumption with a robust tax on gas. The US chose to do it with fuel economy standards. The standards were worked around by auto companies selling SUVs.
If we had today a $4/gallon tax on gas, we'd have fewer roads, denser development, and much lower carbon emissions.
The gas tax is a political lightning rod, but increasing it would help our planet. It's hard for me to say which of many effects would be biggest, but if you and your kids could help get a gas tax put in place, you'd be doing the world a great service.
