How It Works

How to Calculate Carbon Offset Costs

Carbon offsets let you compensate for emissions by funding projects that reduce CO2 elsewhere.

Formula

Cost = CO2 Tons * Price per Ton

Typical Prices

  • Renewable energy credits: $5-15/ton
  • Forest conservation: $10-25/ton
  • Direct air capture: $100-600/ton

    • Worked Example

    Offset a 12-ton annual footprint at $15 per ton.

    co2_tons = 12price_per_ton = 15
    1. 01Total cost: 12 * $15 = $180 per year
    2. 02Monthly: $180 / 12 = $15/month
    3. 03Daily: $180 / 365 = $0.49/day
