How do they come up with the correlation of CO2 emissions and planting trees?

Question

I recently saw this: “An average router consumes 6 watts of electricity an hour. Leaving a router on for a year creates about 24 KG of CO2. If you switch your router off for an average of 8 hours a day, that’s the equivalent of planting one tree.” I have no idea what flair this falls under.

Answer 1

Electricity usually is generated by some sort of CO2 producing action if not from dams, nuclear power, or solar. They take the average CO2 production needed to generate one kw over a massive sample size. Then they take the average CO2 absorbing rate of one tree over a massive sample size. They do some math and say, “x amount of kw used equals 1 tree.”
