Calculate CO2 emissions for shipments by weight, distance, and transport method with environmental equivalents
This calculator estimates CO2 emissions based on internationally recognized emission factors for different transport methods. The calculations consider both the weight of the shipment and the distance traveled.
Calculate emissions for e-commerce product shipping, compare transport methods for sustainability reporting, and understand environmental impact of logistics decisions.
Answers about emission factor accuracy, eco-friendly transport methods, tree equivalent calculations, and carbon offset programs.
How accurate are the emission factors?
The emission factors used are based on internationally recognized standards from DEFRA and EPA. They represent average values for each transport method. Actual emissions may vary based on vehicle efficiency, load factors, and route optimization.
What is the most eco-friendly shipping method?
Shipping by train and sea (ship) typically have the lowest carbon emissions per ton-km. Air freight has the highest emissions. Truck emissions fall in between. For long distances, consider combining methods (e.g., truck to rail to ship).
How are tree equivalents calculated?
Tree equivalents are calculated based on the average amount of CO2 a mature tree absorbs per year (approximately 22 kg). This provides a relatable way to understand the scale of emissions, though actual carbon sequestration varies by tree species, age, and environment.
Can I offset my shipping emissions?
Yes, many carbon offset programs allow you to purchase carbon credits to neutralize your shipping emissions. This calculator helps you understand the scale of emissions before choosing an offset program. Consider reducing emissions first through efficient routing and transport method selection.
Strategies for consolidating shipments, optimizing routes, choosing efficient transport methods, and selecting local suppliers to reduce emissions.
Reference values for CO2 emission factors by transport method
Truck: 0.089 kg CO2 per ton-km (medium-duty diesel)
Ship: 0.015 kg CO2 per ton-km (container ship)
Air: 0.592 kg CO2 per ton-km (freight aircraft)
Train: 0.028 kg CO2 per ton-km (electric rail)
