Carbon-Neutral Shipping Cost Calculator

Project freight-related greenhouse gas emissions and the offset or inset spend required to make a shipping programme carbon-neutral for a reporting period.

Total number of parcels or freight consignments you plan to cover.
Mean chargeable weight per shipment in kilograms.
Door-to-door distance travelled by each shipment.
Use the appropriate factor for your dominant transport mode, expressed in grams of CO2e per tonne-kilometre.
Defaults to $0. Enter the per-tonne price for high-quality credits or operational insets.
Defaults to 0%. Represents emission cuts from efficiency projects before offsets are applied.

Validate emission factors and credit quality with sustainability specialists before marketing carbon-neutral shipping offers.

Examples

  • 2,500 shipments, 6.5 kg each, 820 km average distance, 520 g/tkm factor, $18/t credits, 12% operational reduction ⇒ Carbon-neutral shipping load: 6.11 tonnes CO2e after applying 12.00% operational reductions. Budget: $109.92 at $18.00/t.
  • 1,000 shipments, 12 kg each, 450 km average distance, 410 g/tkm factor, optional fields blank ⇒ Carbon-neutral shipping load: 5.54 tonnes CO2e. Budget: $0.00 at a $0.00/t credit price.

FAQ

Which emission factor should I use?

Select the factor published by recognized databases such as Smart Freight Centre or GLEC for the dominant leg of transport. Use air freight factors for express lanes and trucking factors for regional ground services.

Can I include packaging improvements?

Yes. If lighter packaging or right-sizing reduces average shipment weight, update the weight input and adjust the operational reduction percentage to capture the verified savings.

How often should I recalculate?

Update the inputs whenever shipment volume, lane mix, or offset pricing changes materially. Many retailers refresh this monthly to manage accruals and supplier invoices.

Does this guarantee carbon neutrality?

The calculator quantifies tonnes and budget based on your inputs. You still need to procure high-quality offsets or insets and document claims per standards such as the GHG Protocol and ISO 14068.

Additional Information

  • Emission factors expressed in grams per tonne-kilometre scale parcel weight and distance into total CO2e.
  • Operational reductions represent verified process improvements that lower emissions before offsets.
  • Offset budget multiplies net tonnes by the per-tonne credit or inset price you negotiate with suppliers.
