# CO

## Trees are a “natural antidote” against CO_{2}.

### Through photosynthesis, trees absorb CO_{2} from the atmosphere by returning oxygen. A tree absorbs, on average, about 10kg of CO_{2} per year, so you can easily calculate how many trees you need to absorb the CO_{2} you produce.

Tree can be an intuitive way for measuring C0_{2}. Therefore we can measure the carbon footprint of anything, even of our way of life, measuring it in trees. The more C0_{2} we generate, the greater our impact on the planet is, the greater is the amount of trees we need to keep the planet in balance.

On the opposite we can imagine the C0_{2} we generate in terms of trees that we subtract to planet balance.

Although there are trees of very different shapes, sizes and characteristics, the United Nations Convention on Climate Change (UNFCCC) states that a tree absorbs each year an average of about 10kg of C0_{2}, ie 27g per day.

To understand therefore how many trees you need, you can simply divide by 10 the annual CO_{2} amount expressed in kg, or by 27 the daily CO_{2} amount expressed in grams.
