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

Electric appliances use energy. Power plants make energy often times by burning fossil fuels. By calculating the amount of fuel needed to power your router we can also calculate the amount of pollution as a result.

Essentially someone did the calculation and reached the power needs for a year and compared the resulting pollution to the amount that could be absorbed by a tree.

Solution, go plant a tree and let your router run.
