Crazy idea for pollution control

I was thinking strongly over the weekend for some solution to "pollution control". For understanding pollution, I have noted down following points.

1. I'm not good in chemistry, but still have some idea of CO₂ (Carbon dioxide) & O₂ (Oxygen). They are the chemicals behind polluted air and fresh air.
2. CO₂ is majorly generated by Automobiles, Air conditioners, fridges etc., what we use everyday for convenience and luxury.
3. O₂ will be generated by Trees. Trees have a huge advantage, they not only produce O₂, they also consume CO₂. Its kind of double bonus.

Everybody know the solution now, Plant trees and end pollution . People knows this from years and still nobody is doing that.

I feel there should be a mechanism which will calculate the pollution created by each individual and which will also tell how many trees they have to plant to balance the pollution. And if we can found that mechanism, government can make it mandatory to plant trees to balance their own pollution. People should not ask for an  excuse saying, it is very costly affair to get land in cities for planting trees. Because cars, air conditioners & refrigerators are also costly things.

If it is difficult for people to follow this, companies who manufacture cars, air conditioners & refrigerators can take it as a responsibility and plant trees. They can charge some additional money to customers for this. So where ever they have more sales they have to plant more trees.

It is in my thought process and I welcome all your feedback in comments section.
