Freight Carbon Offset Cost Calculator — Logistics Scope 3 Emissions

Calculate freight carbon emissions and offset cost for your logistics operations. Model Scope 3 transport emissions and find the cost of a carbon-neutral shipping program.

Quick answer: Carbon offset prices: $8–$25/tonne CO₂ for basic offsets, $20–$60/tonne for high-quality verified offsets. A 10-truck fleet driving 1.2M miles/year emits ~370 tonnes CO₂ — offsetting costs $3,000–$22,000/year.

How to Use This Calculator

Enter annual tonne-km volume — from your TMS or carrier reports — weight per shipment × distance, summed annually.
Select freight mode — auto-fills emission factor. Air is 30–50× more carbon-intensive than ocean; intermodal 60–70% less than truckload.
Set offset price — use verified carbon standards (VCS, Gold Standard) for credible offsets — budget $15–$50/tonne.

Worked Example

$3M freight spend, FTL dominant, 5M tonne-km, 90g CO₂/tonne-km, $18/tonne offset, 100% offset.

Annual CO₂: 5M × 90 ÷ 1M = 450 tonnes
Offset cost: 450 × $18 = $8,100/yr
As % of freight spend: 0.27%

Carbon offsetting is very affordable relative to freight spend — typically 0.1–0.5%. More impactful: modal shift from air to ocean (cuts emissions 95%, saves freight cost too) or fleet electrification. Offsets should complement reduction efforts, not replace them.

Frequently Asked Questions

Scope 3 includes indirect emissions from the value chain — for most companies, freight and logistics is the largest Scope 3 category. Under GHG Protocol guidelines, companies categorise freight emissions as Category 4 (upstream transport) or Category 9 (downstream transport). Many corporate sustainability targets now include Scope 3 reduction commitments.

Offsets verified under Verified Carbon Standard (VCS/Verra), Gold Standard, or American Carbon Registry. Look for permanence (forests that won't be cut), additionality (wouldn't have happened without offset revenue), and third-party verification. Avoid cheap, unverified offsets — they undermine credibility. Price premium for quality is worth it.
