🌱 GreenLeaf - CO₂ Calculator App

GreenLeaf is an Android application designed to raise awareness about environmental preservation by calculating the estimated amount of CO₂ removed from the atmosphere based on tree planting.

📌 Why We Developed This App

Deforestation and wildfires in biomes like the Brazilian Cerrado release enormous amounts of CO₂, worsening climate change. We created GreenLeaf to:
✅ Show the positive impact of tree planting in reducing atmospheric CO₂.
✅ Encourage reforestation by making the benefits measurable.
✅ Promote environmental awareness in a simple and interactive way.

🛠️ Technologies Used

• Developed with MIT App Inventor (a visual programming tool for Android apps).
• Simple and intuitive interface for easy use.

📱 How It Works

1. User Input:

   • Upon opening the app, the user is prompted to enter the number of trees planted (as a whole number).

2. Automatic Calculation:

   • The app calculates how much CO₂ can be removed from the atmosphere based on scientific estimates (each tree absorbs ~22 kg of CO₂ per year on average).

3. Result Display:

   • The app shows the total CO₂ reduction in kilograms (kg).

🔹 Key Features

✔ Simple & Fast – Just input the number of trees and get an instant result.
✔ Educational – Helps users understand the environmental impact of tree planting.
✔ Lightweight – Small APK size, compatible with most Android devices.

📥 Download & Installation
