🌿 Carbon Credit Calculator — ACCU Income

Estimate your annual income from Australian Carbon Credit Units (ACCUs). Calculate revenue from human-induced regeneration, environmental plantings, soil carbon, and other carbon farming methods.

Quick answer: For 500 hectares at 10 tCO2/ha/year and $35/t = 5,000 ACCUs worth $175,000 annually. Income varies by method, region, and carbon price.

🌿 Calculate Carbon Credit Income

Total hectares where carbon farming practices are implemented
Soil: 0.5-5 t, Planting: 5-20 t, Regeneration: 3-15 t
ACCU spot price $30-45. Voluntary market $15-25. Govt contracts $25-35.
Annual Carbon Income
Total ACCUs per Year
Income per Hectare

📐 How Carbon Credits Are Calculated

Total CO₂e sequestered = Area (ha) × Sequestration Rate (tCO₂/ha/year)
Annual Income = Total CO₂e × Carbon Price ($/t)
Income per Hectare = Sequestration Rate × Carbon Price
  1. Measure eligible area — hectares where practice change is implemented
  2. Determine sequestration rate — based on method, rainfall, soil type
  3. Check current carbon price — ACCU spot, voluntary market, or contract
  4. Calculate annual credits — multiply area by sequestration rate
  5. Calculate annual income — multiply credits by carbon price

📊 Worked Example

A farmer in NSW converts 500 hectares to environmental plantings. Sequestration rate: 12 tCO₂/ha/year. Carbon price: $35/t ACCU.

Total CO₂e = 500 × 12 = 6,000 tonnes/year
Annual Income = 6,000 × $35 = $210,000
Income per Hectare = 12 × $35 = $420/ha/year

Over a 10-year project, this generates 60,000 ACCUs worth over $2 million in gross revenue.

❓ Frequently Asked Questions

Annual carbon credits = Area (ha) × Sequestration rate (tCO2/ha/year) × Carbon price ($/t). Example: 500ha × 10t × $35 = 5,000 ACCUs worth $175,000 per year.

Human-induced regeneration (natural regrowth), environmental plantings, soil carbon sequestration (improved grazing management, stubble retention, reduced tillage), savanna fire management, and reforestation.

Soil carbon: 0.5-5 tCO2/ha/year. Environmental plantings: 5-20 tCO2/ha/year. Human-induced regeneration: 3-15 tCO2/ha/year. Rates vary by rainfall, soil type, and management.

As of 2026, ACCU spot prices range from $30-45 per unit. Voluntary market credits trade lower at $15-25. Long-term government contracts offer $25-35 fixed.
