Carbon Calculator - Brazil

A small, browser-based CO₂ emissions calculator for trips in Brazil. It lets you pick origin/destination (Brazilian state capitals), auto-fills the distance, and estimates total CO₂ emissions based on the chosen transport mode. It also shows environmental equivalents and a simple impact analysis with recommendations.

📚 Features

• Select origin and destination from all Brazilian capitals
• Auto-calculates distance (with a road-distance approximation and specific route overrides)
• Transport-mode emission factors (g/km) driven by a single configuration file
• Calculates total CO₂ emissions (supports round trip and monthly frequency)
• Shows environmental equivalents (trees, smartphone charges, kWh, and “average car km”)
• Impact analysis (Low/Medium/High) with recommendations

🚀 Built With

• HTML5
• CSS3 (responsive layout + design tokens via CSS variables)
• Vanilla JavaScript (ES Modules)
