I wrote this in response to a reply comment (since deleted). But I spent enough time that I wanted to post it:

You can make massively meaning differences every day with minor personal decisions. If everyone in the US did them it would have a significant global impact.

1. Replace all bulbs with LEDs. 2. Set your AC warmer at home, in the thermostat in your hotel rooms, and anywhere else you can 3. Eat as little meat as you can 4. Replace your car with an EV or highly fuel efficient hybrid 5. Get the highest efficiency AC/Heater 6. Change vacation plans to avoid CO2 emission 7. Install Solar PV. 8 Lower your hot water temperature 9. Repair instead of replace 10. Up the R value of your insulation...

You can make a huge dent (more than 50%) in your personal CO2 footprint. PARTICULARLY as a member of an industrialized society. You can make more impact than a dozen people in a developing country.
