Carbon Footprint Calculator | Shipping CO₂ Emissions

📘 How CO₂ emissions are estimated

• CO₂e (kg) = weight (tonnes) × distance (km) × emission factor (kg CO₂ per tonne-km). Includes a peak-season uplift if selected.
• Emission factors follow the GLEC Framework (Smart Freight Centre) and IMO 2023 fuel-efficiency baselines: ocean container ~10 g/t-km, air freight ~500 g/t-km, road ~60 g/t-km, rail ~22 g/t-km.
• ⚠ Estimates exclude well-to-tank (WTT) upstream fuel emissions, port handling, last-mile drayage, and refrigerated cargo (reefer adds ~10–20%). Use a verified ISO 14083 audit for compliance reporting.
• Carbon offsets shown are indicative AUD retail prices. True carbon neutrality requires third-party verified credits (Gold Standard, Verra/VCS, ACCU).
• Trees-equivalent assumes a mature tree absorbs ~21 kg CO₂/year over 40 years.
