That's a good analysis. Here's an excerpt: """ Under the constant scenario, an American who forgoes having a child would save 9,441 tonnes of CO2 – almost six times, on average, the amount of CO2 they would emit in their own lifetime, or the equivalent of making around 2,550 return aero­plane trips between London and New York. If the same American drove a more fuel-efficient car, drastically reduced his or her driving, installed energy-efficient windows, used energy-efficient lightbulbs, replaced a household refrigerator, and recycled all household paper, glass and metal, he or she would save fewer than 500 tonnes.
