What are market-based measures in transport decarbonisation?
Market-based measures are becoming an important part of transport decarbonisation. They help companies reduce logistics emissions when direct access to low-emission transport solutions is limited, fragmented or not yet available on every route.
For cargo owners, freight forwarders, transport platforms and companies with Scope 3 logistics emissions, this matters. Many businesses want to reduce transport-related emissions, but they do not always control the vessel, truck, aircraft, barge, route or fuel decision. Market-based measures help bridge that gap.
In simple terms: market-based measures allow companies to financially support lower-emission transport solutions and claim the related CO₂e reduction through a controlled accounting and reporting system. In transport, this is often done through Book & Claim, digital registries and certificates that document the environmental attribute of a low-emission transport service.
What are market-based measures in transport?
Market-based measures in transport are mechanisms that allow companies to account for and report emissions reductions from low-emission transport solutions, even when the physical transport service and the buyer’s own shipment are not directly connected.
Smart Freight Centre describes its Market Based Measures Program as enabling market-based accounting approaches for transportation greenhouse gas emissions, with a focus on flexible chain-of-custody models including Book & Claim. The program aims to stay consistent with the GLEC Framework and ISO 14083 (Smart Freight Centre).
In practice, market-based measures can help companies support sustainable fuels, electric transport, low-emission freight services or other transport decarbonization solutions. The environmental benefit is recorded, allocated and retired according to a methodology, so the buyer can use the reduction for reporting or customer claims.
Why do market-based measures matter for logistics emissions?
Market-based measures matter because transport supply chains are difficult to decarbonize through direct action alone.
A company may have ocean freight emissions across global trade lanes, road transport across multiple countries, air freight through different carriers and inland transport managed by logistics partners. Sustainable fuels or low-emission services may be available in one part of the network, but not on the exact route where the company ships goods.
Market-based measures make it possible to connect demand and supply more efficiently. Companies can support low-emission transport where it is available, while the resulting CO₂e reduction is allocated to the buyer through a controlled system. This helps accelerate demand for sustainable fuels and low-emission transport services across the market.
The International Transport Forum describes Book & Claim as a model that enables environmental attributes of low-emission fuels or services to be procured independently of their physical delivery, helping match demand with supply when they are physically disconnected (International Transport Forum).
How do market-based measures work in practice?
Most market-based measures in transport follow the same basic logic.
First, a low-emission transport solution is deployed. This could be sustainable marine fuel, HVO100 in road transport, sustainable aviation fuel, low-emission inland shipping or another verified lower-emission transport service.
Second, the emissions reduction is calculated and documented. This requires data on the fuel or service, the baseline, the emissions factor, the transport activity and the reduction achieved.
Third, the environmental attribute is issued as a certificate or unit in a registry. This certificate represents the right to claim a specific CO₂e reduction or low-emission transport service attribute.
Fourth, the certificate is allocated and retired. Once it is retired, it can no longer be sold, transferred or claimed again.
This structure is designed to make climate claims traceable and to prevent double counting.
What is the role of Book & Claim in market-based measures?
Book & Claim is one of the most important chain-of-custody models for market-based measures in transport.
In a Book & Claim system, the physical fuel or low-emission transport service is separated from the environmental attribute. The sustainable fuel is used where it can create impact, while the related CO₂e reduction is recorded in a digital registry. A buyer can then claim that reduction when the certificate is allocated and retired.
RSB explains that Book & Claim decouples sustainability attributes from the physical product and registers them as Book & Claim Units, or BCUs, in a registry (RSB Registry).
This is especially useful in freight transport. It allows companies to support decarbonization even when sustainable fuel is not physically available on their own route or shipment. For the climate, what matters is that fossil fuel is replaced and the environmental attribute is claimed only once.
What is the difference between market-based measures and direct emissions reduction?
Direct emissions reduction means the company reduces emissions in its own physical activity or directly purchased service. For example, a transport company may run its own trucks on HVO100 or electricity. A shipper may contract a carrier to use sustainable fuel on a specific route.
Market-based measures are different because the reduction does not always need to happen in the buyer’s exact physical transport flow. Instead, the buyer supports a low-emission transport activity elsewhere in the transport system and receives the verified environmental attribute.
That does not make market-based measures the same as carbon offsetting. Strong transport market-based measures are designed to create reductions within the transport value chain itself. That is why they are often linked to transport insetting, not external compensation.
Are market-based measures the same as carbon offsetting?
No. Market-based measures in transport are not the same as traditional carbon offsetting.
Carbon offsetting usually compensates emissions through projects outside the company’s value chain, such as forestry, renewable energy projects or carbon removal. Market-based measures for transport focus on reducing emissions within the transport sector itself.
For example, a company with ocean freight emissions can use a Book & Claim mechanism to support sustainable marine fuel use in the shipping sector. A company with road transport emissions can support HVO100 use in road transport. In both cases, the reduction takes place inside the transport value chain.
This is why market-based measures can be an important tool for transport insetting. They help companies move from compensation outside the chain to reduction within the sector where the emissions occur.
What are EACs in transport decarbonisation?
EAC stands for Environmental Attribute Certificate. It is a broad term for a certificate that represents an environmental attribute, such as a CO₂e reduction or the use of a low-emission fuel or service.
In electricity markets, similar certificates are used to represent renewable energy attributes. In transport, EAC is increasingly used as an umbrella term for certificates that document and transfer the environmental benefit of low-emission transport solutions. Katalist describes EAC as a broad umbrella term for instruments that document, transfer and enable claims on environmental benefits across sectors, fuel types and registry designs (Katalist).
For transport decarbonisation, an EAC can represent the environmental benefit of sustainable fuel use or a low-emission transport service. The exact meaning depends on the methodology, registry and claim rules behind it.
What are LETS in market-based transport accounting?
LETS stands for Low Emission Transportation Service.
In the context of market-based measures, LETS describes the low-emission freight service that creates the environmental benefit. This could be a transport service performed with sustainable fuel, electricity, hydrogen or another lower-emission solution, depending on the methodology.
The term is used in the transport decarbonization market to describe the underlying service that creates the emissions reduction. In simple terms: the LETS is the low-emission transport activity, while the certificate or unit represents the claimable environmental attribute linked to that activity.
For companies, LETS are important because they connect the market-based claim to a real transport service, not only to an abstract certificate.
What are BCUs in Book & Claim systems?
BCU stands for Book & Claim Unit.
A BCU is usually the unit created in a Book & Claim registry to represent the environmental attribute of a sustainable fuel or low-emission transport service. It can be issued, transferred and retired according to the rules of the registry.
The RSB Book & Claim Registry uses BCUs to register sustainability attributes that have been decoupled from the physical product. The registry tracks and retires BCUs to support credible sustainability claims (RSB Registry).
In practice, a BCU is one way to name the tradable or claimable unit in a Book & Claim system. Other systems may use different names, but the core function is similar: document the environmental attribute and make sure it is only claimed once.
What are TIECs in Book & Claim?
TIEC stands for Transferable Instrument with Entitlement to Claim.
It is a term used to describe a transferable instrument that gives the holder the right to make a claim about a specific environmental attribute. In Book & Claim discussions, TIEC is used to create more precise language around what exactly is transferred from the party creating the reduction to the party making the claim.
The International Transport Forum lists TIEC as “Transferable Instrument with Entitlement to Claim” in its Book & Claim terminology (International Transport Forum).
A practical way to understand it: a TIEC is not the low-emission transport service itself. It is the instrument that carries the right to claim the associated environmental benefit, under the rules of a Book & Claim system.
What are market-based instruments?
Market-based instruments is the broadest term in this field.
It can refer to any instrument that enables environmental benefits, emissions reductions or low-emission service attributes to be purchased, transferred, allocated or claimed through a market mechanism. EACs, BCUs and TIECs can all be considered types of market-based instruments, depending on the system.
In transport decarbonization, market-based instruments are often used to create demand for sustainable fuels and low-emission freight services. They allow companies to support decarbonization beyond their own direct fuel supply, while still maintaining a clear chain of custody for the environmental claim.
What is the difference between EACs, LETS, BCUs, TIECs and market-based measures?
The terms are related, but they do not mean the same thing.
Market-based measures are the overall accounting and reporting approach. They describe the mechanism that allows companies to use market systems to support and claim transport emissions reductions.
Market-based instruments are the transferable instruments used within that approach. They carry the environmental attribute or the right to claim it.
EACs are a broad category of certificates that represent environmental attributes, such as CO₂e reductions or sustainable fuel attributes.
LETS are the low-emission transport services that create the emissions reduction in the first place.
BCUs are Book & Claim Units, usually issued in a Book & Claim registry to represent a claimable environmental attribute.
TIECs are transferable instruments with entitlement to claim. They describe the right to make a claim about the environmental attribute.
A simple way to remember it: LETS create the reduction. EACs, BCUs or TIECs carry the claim. Market-based measures define the accounting approach.
How do market-based measures prevent double counting?
Market-based measures prevent double counting through registries, unique certificates, clear allocation rules and retirement.
A credible system should record when a CO₂e reduction is created, who owns or receives the related environmental attribute, and when the certificate is retired. Once retired, the same reduction should not be sold, transferred or claimed again.
The Book and Claim Community notes that certification of environmental attributes does not automatically validate the legitimacy of the certificate itself. The certificate, unit or token also needs robust system controls, governance and claims management (Book and Claim Community).
That distinction is important. Sustainable fuel documentation proves that the fuel meets certain criteria. A Book & Claim registry proves who has the right to claim the environmental benefit and whether that claim has already been used.
Which standards and frameworks are relevant for market-based measures?
Several standards and frameworks are relevant for market-based measures in transport.
Smart Freight Centre’s Market Based Measures Framework and MBM Specification are central references for logistics emissions reporting. SFC states that the MBM Framework and MBM Specification set rules for reporting emissions under its Conformity Assessment Scheme, and that the framework is being revised to version 2.0 (Smart Freight Centre).
Other relevant frameworks include the GLEC Framework, ISO 14083, the GHG Protocol, ISO 22095 and sustainability certification schemes for fuels such as ISCC, RSB and REDcert. The exact combination depends on the transport mode, fuel type, market, reporting purpose and customer claim.
For companies, the key is not only which standard is named, but how the system applies it. The methodology should be transparent, auditable and fit for the type of claim being made.
How do market-based measures support Scope 3 reporting?
Market-based measures can help companies address Scope 3 transport emissions when they do not directly control the transport asset or fuel choice.
A cargo owner may buy logistics services from a freight forwarder. A retailer may ship goods through multiple carriers. A manufacturer may have ocean freight, road transport and air freight emissions across its value chain. In all these cases, the company may need a credible way to reduce and report transport emissions without physically managing the fuel supply.
Market-based measures can allocate verified CO₂e reductions to the company’s transport footprint. When supported by strong documentation, registry controls and third party verification, this can provide a clearer basis for Scope 3 reporting and customer communication.
When should a company use market-based measures?
A company should consider market-based measures when it wants to reduce transport emissions, but direct physical access to low-emission transport is limited.
This is common when sustainable fuel is not available on a specific route, when the company does not control the carrier, when shipments are spread across many logistics providers or when freight forwarders want to allocate reductions to many end customers.
Market-based measures are also useful when a company wants to scale action quickly. Instead of waiting until every route, carrier and fuel contract is ready, the company can support low-emission transport where it is available and claim the corresponding reduction through a controlled system.
What should companies look for in a credible market-based measure?
A credible market-based measure should be transparent, traceable and verifiable.
Companies should look for a clear methodology, reliable emissions calculations, proof of the low-emission transport activity, third party verification, unique certificates, registry-based allocation and retirement, and strong rules to prevent double counting.
They should also check whether the solution is connected to real transport decarbonization. A strong market-based measure should not only move certificates around. It should help create demand for sustainable fuels or low-emission services in the transport sector itself.
For companies seeking a practical and scalable solution, platforms like Decarb Desk provide a centralized way to manage Book & Claim transactions, allocate CO₂e reductions, and ensure traceability and compliance across transport modes.
How does FincoEnergies apply market-based measures in transport?
FincoEnergies applies market-based measures through solutions such as GoodShipping, Biofuel Swap and Decarb Desk.
GoodShipping supports ocean freight insetting through the use of sustainable marine biofuels. Biofuel Swap supports road insetting through HVO100, with an average CO₂e reduction of 85% compared to diesel. Decarb Desk provides the digital platform and registry to create, allocate and retire CO₂e reduction certificates across transport modalities.
The reductions are generated through sustainable biofuels in transport, documented with traceability data and supported by third party verification. This makes it possible for cargo owners, freight forwarders, resellers and platforms to allocate CO₂e reductions to customers, shipments or reporting periods in a controlled way.
What is the key takeaway on market-based measures in transport decarbonisation?
Market-based measures help companies act on transport emissions when physical decarbonisation is complex, fragmented or not yet available on every route.
They are not a replacement for operational improvements, electrification, efficiency or direct sustainable fuel use. They are a practical tool to accelerate action across global logistics chains, especially where companies have Scope 3 emissions but limited control over the physical transport operation.
The most important point is integrity. Market-based measures only work when the reduction is real, the certificate is unique, the claim is traceable and the retirement is final.
Used well, market-based measures can help companies move from climate ambition to measurable transport decarbonisation, while supporting the growth of sustainable fuels and lower-emission freight services across the market.
