Environmental Impact Calculator

Estimate your project’s environmental benefits:

Carbon Offset Formula

• Annual kWh generation × local grid carbon intensity (kg CO2/kWh)
• Example: 10,000 kWh × 0.45 kg CO2/kWh = 4,500 kg (4.5 tons) CO2 offset

Tree Equivalent

• Approximately 50-100 trees planted per ton of CO2 offset
• Example: 4.5 tons = 225-450 tree equivalents

Vehicle Miles Avoided
