Formula
CO₂/ano = árvores × 22 kg; energia = árvores × 35 kWh; água = árvores × 2400 L/ano
About this calculator
The Tree Benefits Calculator estimates the environmental gains from planting one or more trees. Based on average values per tree, it calculates annual CO₂ reduction, energy savings, and water retention. For instance, a mature tree can absorb about 22 kg of CO₂ per year, reduce energy consumption by 35 kWh, and capture approximately 2,400 liters of rainwater. This tool is ideal for demonstrating the positive impact of reforestation in personal, community, or business projects.
How it works: the user inputs the number of trees planted or planned. The calculator multiplies that number by fixed factors (22 kg CO₂, 35 kWh, 2,400 L) to obtain annual totals. These values are scientific averages, but can vary by species, climate, and tree age. The tool serves as an initial guide for environmental awareness and planning, not replacing detailed technical assessments.
When to use? In urban forestry projects, carbon offsetting, environmental education, or to calculate the benefit of an orchard or garden. It is also useful for companies reporting sustainability goals. Cautions: results are estimates; factors like location, maintenance, and tree type affect actual values. Consider using more precise data for formal reports.
Frequently asked questions
Are the CO₂, energy, and water values accurate for any tree species?
No, they are general averages. Fast-growing or native species may have different values. Check specific data for your region and species.
Does the 35 kWh energy saving per tree apply to homes?
Yes, it is an average of shading and cooling provided by a mature tree, reducing air conditioning use. The actual value depends on location and tree.
How does the calculator account for tree age?
It assumes mature trees (10+ years). Young saplings have smaller benefits. For long-term projects, consider growth over time.
Can I use this calculator to offset carbon emissions from an event?
Yes, as an initial estimate. For formal offsetting, use certified methodologies and more detailed calculations based on tree type and location.
What does the 2,400 liters of water retention per tree mean?
It is the average amount of rainwater a tree intercepts and absorbs, helping prevent floods and recharge aquifers. The value varies with canopy and soil.
