Wondering whether carbon neutral shipping means your parcel emits nothing? It doesn’t. It usually means emissions are measured, then balanced by offsets or cleaner-fuel claims, so check what sits behind the label.
This guide sits within the wider topic of green logistics, which looks at how goods can move with fewer emissions.
| Item | Value |
|---|---|
| Share of SBTi-validated companies with targets naming upstream transport (September 2025) | 8.8% (1,046 of 15,564 companies) |
| Scope 3 emissions compared with Scope 1 and 2, on average | 26 times larger |
| Ocean freight’s share of global CO2 emissions | Roughly 3% |
| Active vessels able to run on alternative fuels | 1.5% (2,493 of 165,000 vessels) |
| Carbon-intensity cut required of international shipping by 2030 | 40% from 2008 levels |
The figures come from Lloyd’s Register’s analysis and a freight forwarder’s Ship Green page. They can change, so check the source before you rely on them.
What a carbon neutral label actually claims
A carbon neutral claim is an accounting balance, not a physical fact. Someone measures the emissions from moving goods, then compensates for them in some way. The ship still burns fuel and the container still has a footprint.
Sustainable Travel International, which sells offsets, puts the case this way: moving goods around the world isn’t going away, and fully decarbonizing shipping will take time. Its argument is that offsets let businesses support climate projects now while they keep cutting their own shipment emissions.
That is a fair description of the idea, but it also shows the limit. Neutral means “balanced on paper”, so the quality of the measurement and of the balancing method decides whether the label is meaningful.
Why shippers are asking for it
Pressure comes largely from Scope 3 reporting. According to Lloyd’s Register, Scope 3 emissions are on average 26 times larger than a company’s direct Scope 1 and 2 emissions. For many retailers and manufacturers, transport is the largest single piece of that total.
The GHG Protocol’s Category 4 covers upstream transportation and distribution. In September 2025, 8.8% of companies in the SBTi database (1,046 of 15,564) had validated near-term targets naming it. The sectors with the most such companies were:
- Food and beverage: 152 companies
- Textiles and apparel: 91 companies
- Pharmaceuticals: 89 companies
- Retail: 70 companies
Shoppers add to the push. A 2021 Sifted figure quoted by Sustainable Travel International says 91% of consumers want to see an “eco-friendly shipping” option at checkout. That is a survey figure quoted by an offset seller, so treat it as a sign of interest rather than proof of behaviour.
How shipping emissions get measured
No neutrality claim is better than the number underneath it. The GLEC Framework was developed by the Smart Freight Centre in 2016 and aligns with the Greenhouse Gas Protocol, according to a software vendor’s guide. The same guide says it now integrates with the ISO 14083 standard, and a companion post reports that version 3.2 was published on 23 October 2025.
The guide describes three ways to calculate a shipment’s CO2e:
- Primary data: real fuel use and distances for the shipment, which is accurate but hard to get because most carriers don’t share it.
- Default data: industry-average factors, which are easy to use but ignore vessel type, route and speed.
- Modelled data: shipment details combined with vessel models, a middle path that needs advanced tools.
The guide’s default example multiplies a factor of 49 g CO2e per km by 19,700 km for a container from Shanghai to Antwerp, giving 965 kg CO2e. A separate primary-data example, a vessel using 4,600 tonnes of fuel to carry 15,000 TEU, works out at 1,046 kg CO2e per TEU. The two come from different examples, so don’t compare them directly. They do show that the same label can rest on very different methods.
Offsetting versus insetting
Most carbon neutral shipping uses offsets: you pay for climate projects outside your supply chain. Sustainable Travel International says its projects are independently verified by standards such as the Gold Standard and Verified Carbon Standard, which evaluate criteria such as additionality, permanence and leakage.
The alternative is insetting. Gateway Lines, a freight forwarder, says ocean freight produces roughly 3% of global CO2 emissions and that insetting removes emissions from the shipping system itself. Its description is that sustainable marine fuel replaces fossil fuel on working vessels, tracked through a Book and Claim system so nothing is counted twice.
Both are sellers’ descriptions, so test them rather than assume them. The practical differences are:
- Offsets fund projects elsewhere, while your freight still burns the same fuel.
- Insetting aims at the fuel used in the chain that moves your cargo.
- Either way, the claim is only as strong as the verification behind it.
Why the fleet limits what the label can mean
Even a well-measured claim runs into the state of the fleet. Lloyd’s Register notes that the IMO’s revised GHG Strategy requires international shipping to cut its carbon intensity by 40% from 2008 levels by 2030. Of 165,000 active vessels, just 1.5% (2,493) could run on alternative fuels, and 41% of the global fleet is 25 years old or more.
Policy is also unsettled. As of Lloyd’s Register’s November 2026 analysis, the proposed Net Zero Fund, a $150-per-tonne charge on shipping CO2 emissions meant to raise some $120 billion a year, remained unagreed after the IMO’s April 2025 meeting ended without consensus.
So a shipment can be called neutral while the vessel is a conventional one. That is why the label says little about the ship itself.
Beyond the label: other ways to cut freight emissions
Compensation is only one lever. For the final leg of a journey, electric delivery vehicles are one option that changes the vehicle rather than the paperwork.
Goods that travel back also carry emissions, a topic covered in the guide to reverse logistics.
Questions to ask before you trust a label
Whether you buy shipping or read a supplier’s report, a few checks separate a solid claim from a slogan:
- What was measured, and does the method follow the GLEC Framework or ISO 14083?
- Is the number based on primary, default or modelled data?
- Is the balance made through offsets or insetting, and who verifies it?
- Is each reduction claimed only once?
- What is being done to cut emissions on the shipment itself?
Frequently asked questions
Does carbon neutral shipping mean zero emissions?
Show answer
No. The shipment still produces emissions. Neutral means they are measured and then balanced through offsets or a fuel-based reduction claim.
Is carbon neutral shipping the same as offsetting?
Show answer
Often, but not always. Offsetting funds projects outside the supply chain, while insetting, as Gateway Lines describes it, aims at reductions inside the shipping system.
Which standard is used to calculate shipping emissions?
Show answer
The GLEC Framework is widely used for logistics emissions and, according to this vendor guide, integrates with ISO 14083. Ask any provider which method and data type it uses.
Is there a global carbon charge on shipping?
Show answer
As of Lloyd’s Register’s November 2026 analysis, no. The proposed levy remained unagreed after the IMO’s April 2025 meeting.
