Is your carbon footprint above or below the national average - and if it’s above do you feel bad about it? There are some good calculators online which quiz you on every aspect of you lifestyle. For what it’s worth I’m below average on most metrics - food consumption, energy usage (average sized home with good rating), don’t drive (work from home), only one kid, etc. However, I do fly a fair bit including one long haul every couple of years (12 hour return flight to visit family) - and that alone bumps me right back up to around the national average. I feel kind of bad about it, but there you go.
