Trees Saved Formula:
From: | To: |
Definition: This calculator estimates how many trees are saved based on the amount of paper recycled and the average paper yield per tree.
Purpose: It helps individuals and organizations understand the environmental impact of their paper recycling efforts.
The calculator uses the formula:
Where:
Explanation: The amount of recycled paper is divided by the average paper yield per tree to determine how many trees were effectively saved from being cut down.
Details: Recycling paper conserves natural resources, reduces energy consumption, decreases landfill waste, and helps preserve forests.
Tips: Enter the amount of paper recycled in kilograms and the paper yield per tree (default 12 kg/tree). All values must be > 0.
Q1: How accurate is the 12 kg/tree default value?
A: This is an average - actual yield varies by tree species, size, and paper type.
Q2: Does this account for different paper types?
A: No, for more precision, adjust the paper per tree value based on your specific paper products.
Q3: What's the environmental impact of saving one tree?
A: One tree can absorb about 21 kg of CO2 per year and provide oxygen for 2 people.
Q4: How can I estimate my paper recycling amount?
A: Weigh your paper waste or use standard weights (e.g., office paper ≈ 4.5 kg/ream).
Q5: Does recycling paper really save trees?
A: Yes! Recycling 1 ton of paper can save 17 trees, according to the EPA.
