Build an SBTi trajectory for an industrial SME

1SBTi: move from Bilan Carbone to a science-based trajectory

An SBTi (Science Based Targets initiative) commitment means a company defines emissions reduction targets aligned with climate science, has them validated by an independent third-party organisation, and publishes them on a public dashboard. The methodological framework is led by a partnership between CDP, the UN Global Compact, the World Resources Institute (WRI) and WWF. On 21 May 2026, SBTi published its 2026-2030 strategic plan, marking a shift from "ambition setter" to "transformation partner", with new treatment of companies missing their targets and the introduction of advisory services. At the time this guide was written, in May 2026, the reference standard is version 1.3.1 of the Corporate Net-Zero Standard (patch update published in April 2026), and version 2.0 was published in final form on 11 June 2026, following a second public consultation closed on 12 December 2025.

For an industrial SME, the first driver in 2026 is accumulated regulatory pressure: CBAM entered its definitive phase on 1 January 2026 and taxes the carbon in imports (what it costs in practice); in parallel, free ETS allowances for European producers (steel, cement, aluminium, fertilisers) are being phased out until completely removed in 2034, CSRD requires structured reporting on climate trajectories through ESRS E1 for companies with more than 1,000 employees and €450m turnover, which question their suppliers, and public buyers are starting to request SBTi commitments as a listing criterion. The second driver is access to funding: banks, insurers and investors now recognise an SBTi-validated trajectory in their climate risk assessments.

The third driver is more structural: the framework’s scientific foundation. Unlike self-declared net-zero commitments (such as "50% in 2030") that may be marketing, SBTi bases its targets on IPCC scenarios and requires calibrated annual reduction rates (4.2%/year for 1.5°C using ACA). This makes the trajectory defensible before an auditor, a demanding customer or an investor. The fourth driver is the signal sent to talent and customers: in premium B2B markets, the absence of an SBTi target is becoming an identified competitive disadvantage. By comparison, the sectoral trajectory set by SNBC 3 asks French industry for around -4.5% a year by 2030.

2When to commit and through which route: maturity, SME route or corporate route

The common mistake is rushing into SBTi before establishing the fundamentals. Three maturity criteria determine whether a credible trajectory can be submitted within 12 to 18 months.

First criterion: the baseline. SBTi validates the target using a recent, verifiable measurement including all three scopes. In practice, this means a scope 1+2+3 Bilan Carbone® formalised less than 24 months ago, ideally with an annual updating mechanism. For an industrial SME, scope 3 is the problem: the reported baseline must cover material purchases, upstream transport, downstream use of sold products and end of life. Many companies arrive with a robust scope 1+2 but incomplete scope 3, delaying submission by 6 to 12 months.

Second criterion: an identified reduction plan. SBTi does not validate a vague intention to "reduce emissions", but a credible trajectory. Management must have identified, quantified to an order of magnitude and prioritised the technological and operational levers that will make the target achievable. For an industrial SME, this typically means: electrifying thermal processes, sourcing recycled or bio-based materials, optimising buildings’ energy use, decarbonising the fleet.

Third criterion: capacity for public commitment. The commitment letter signed by the company leader is published on the SBTi dashboard with "Committed" status, making the absence of a validated target publicly visible if the 24-month timetable slips. Management must accept this visibility, and a senior function (CSR director, industrial director or general management) must lead the subject with a clear mandate. An SBTi trajectory led by a junior employee without executive committee support has little chance of completion on time.

SBTi has established a simplified pathway for small and medium-sized enterprises, the SME route. It is intended for companies whose combined scope 1+2 emissions remain below 10,000 tCO2e a year, which employ fewer than 250 people, whose turnover remains below €50 million, whose balance sheet total is below €25 million, and which do not operate in a mandatory FLAG sector (Forest, Land, Agriculture). At least three of these four criteria must be met in addition to the emissions ceiling.

For an industrial SME, the operational threshold is the 10,000 tCO2e scope 1+2 ceiling. This is very low once a site has a furnace, foundry, industrial drying or thermal process. A cement plant, aluminium foundry, glassworks or even an average-sized industrial bakery quickly exceeds it. The SME route remains relevant for low-emission industrial SMEs: electronics assembly, cold food processing, furniture, plastics processing without intensive heating. Above the threshold, the standard corporate route is mandatory.

In practice, the SME route speeds up validation (a few months versus 12 to 30 months for the corporate route), accepts simpler targets (1.5°C absolute reduction scenario, the only acceptable scope 1+2 scenario since July 2022) and does not require a quantified scope 3 target (only a commitment to measure and reduce). By contrast, the corporate route requires a quantified scope 3 target if scope 3 represents more than 40% of the total - the case for almost every industrial SME.

3Method and targets: ACA, SDA, near-term 2030 and net-zero 2050

Beyond choosing the route, SBTi offers two main methods for calculating targets (scientific foundations detailed in Foundations of Science-based Target Setting). The Absolute Contraction Approach (ACA) applies a uniform absolute reduction to all companies not specifically covered by a sectoral method. For near-term scope 1+2, only the 1.5°C scenario has been accepted since 15 July 2022 (4.2%/year rate): the former Well-Below 2°C scenario (2.5%/year) is no longer validated for scope 1+2 and remains only as the minimum acceptable for scope 3. This is the method used by around two thirds of validated companies.

The Sectoral Decarbonization Approach (SDA) is mandatory for intensive industries covered by SBTi sectoral guidance. As of May 2026, finalised methodologies cover: power generation, buildings, steel (July 2023), cement, aviation, chemicals (2025-2026). Methodologies under development cover aluminium, road transport, shipping, oil & gas and hydrogen: for these sectors, SBTi accepts an ACA target pending dedicated guidance, which will then apply. SDA uses decarbonisation pathways published by the International Energy Agency (IEA), expressed as carbon intensity per unit produced (tCO2 per tonne of steel, for example). For finalised sectors, ACA is simply not an acceptable option.

For an industrial SME with multiple activities, the real case is almost always a combination of methods (the official SBTi term): SDA applies to the covered process activity (cement plant, steelworks), ACA to the rest (fleet logistics, tertiary buildings, general purchases). SBTi verifiers expect this explicit combination, documented in the Target Submission Form. An application attempting to apply uniform ACA to a cement plant is returned for correction.

An SBTi trajectory is built over two mandatory horizons since the Corporate Net-Zero Standard. The near-term target covers 5 to 10 years (therefore 2030 or 2035 from 2026), with a reduction calculated through ACA or SDA. For ACA 1.5°C with a 2023 baseline and 2030 target, the calculation is: baseline × (1 - 0.042 × 7) = baseline × 0.706. A 29.4% reduction over 7 years, the minimum acceptable: since the methodological appendix of 14 April 2026, the annual rate is calculated dynamically according to the baseline and target net-zero year, with a 4.2%/year floor. For a 2025 baseline and 2030 target, the minimum falls to 21% (rather than 42% before the appendix), because the trajectory extends to net-zero 2050. The net-zero target aims at 2050 with at least a 90% reduction from the baseline; residual emissions (maximum 10%) can be offset using high-quality carbon credits, but only after actually reducing operational emissions by 90%.

For scope 3, a quantified target is mandatory once scope 3 represents more than 40% of the total. For an industrial SME, this is the general rule. The scope 3 reduction rate may be more flexible than scope 1+2 depending on the standard version, but remains demanding. Under the current V1.3 version, the minimum scope 3 target is a 2.5%/year absolute reduction, or alignment with suppliers’ SBTi-validated commitments (the "supplier engagement target" method).

The mini-calculator below simulates these orders of magnitude; for an official calculation, SBTi provides its own Excel Target Setting Tool (ACA + SDA). Important: this is educational. The official SBTi target may differ according to the method applied by activity, FLAG adjustments if the company is in food or forestry, and the standard version used at submission. Since V2.0 was published on 11 June 2026, a dual-track window allows a choice between V1.3.1 and V2.0 until 31 January 2028; afterwards, V2.0 applies to every new target.

4Methodological pitfalls (and sector-specific characteristics)

Five recurring pitfalls delay submission by several months or lead to outright rejection by SBTi verifiers.

• An outdated or unverifiable baseline. SBTi requires less than five years at submission, but in practice it must be much more recent to remain credible. A 2019 Bilan Carbone® used in 2026 for a 2030 target will be challenged.
• Underestimated scope 3. Reporting 30% then finding 70% once properly measured costs 6 to 12 months of remodelling. The reference remains the GHG Protocol Scope 3 Standard.
• Including offsets in the trajectory. Since April 2024, carbon credits are permitted only for residual emissions, after at least a 90% reduction. A target of 50% reduction + 40% offsetting is rejected.
• Confusing absolute and intensity targets. ACA works in tonnes, SDA in tonnes per unit produced. Intensity targets are accepted only in sectors covered by SDA, with an absolute consistency check.
• Neglecting the CBAM link. For a foundry or cement plant, decarbonising furnaces creates value twice: the SBTi target progresses, and the loss of free ETS allowances (100% in 2034, CBAM timetable) is cushioned by low-carbon investments.

5The validation process: from commitment to publication

The official validation pathway, detailed step by step in the SBTi Corporate Manual, follows five fixed steps, to be completed consecutively over 18 to 30 months.

• Step 1 - Commitment letter. The company leader signs a commitment to set a target within 24 months. The company appears as "Committed" on the public dashboard; missing the deadline changes it to "Commitment Removed", more damaging than not having signed.
• Step 2 - Target development (6 to 12 months). Consolidated scope 1+2+3 baseline, method choice by activity, near-term and net-zero target calculations, preparation of the Target Submission Form.
• Step 3 - Application submission. Submit through the SBTi Services portal and pay fees (varying by SME route / corporate).
• Step 4 - SBTi verifier review (official SBTi SLA: around 30 working days once under review; in practice 3 to 6 months including the queue). The SBTi validation team checks methodological compliance against SBTi Criteria and Recommendations V5.2, the baseline, scope 3 ambition and V1.3 or V2 alignment depending on submission date.
• Step 5 - Approval and publication. "Targets set" status, permission to use the SBTi logo, mandatory annual progress reporting.

6Costs and opportunities: the economic balance for an SME

For direct costs, the budget is bounded and predictable. SBTi validation fees: around €1,150 excl. VAT for the SME route, around €8,800 excl. VAT for a corporate near-term target alone at the bottom of the fee schedule (companies with <€250m turnover), and €13k to €15k excl. VAT for a combined near-term + net-zero package. For the food sector: allow around $7,500 extra for FLAG validation, on top of the fees above (2026 SBTi Services schedule expressed in USD, turnover tiers; indicative conversion). Consultancy support: €15k to €40k excl. VAT to structure the scope 3 baseline, model targets and prepare the Target Submission Form, depending on the maturity of the initial Bilan Carbone®. The hidden internal cost: 0.3 to 0.8 FTE over 12 to 24 months in CSR management, finance and industrial functions. For an industrial SME with 80 to 250 employees, two cost readings coexist. External budget (what you invoice): €20k to €55k excl. VAT = SBTi validation fees + consultancy support. Full investment: €60k to €120k spread over two financial years, including valued internal time (0.3 to 0.8 FTE). This distinction avoids overstating the actual cost when benchmarking suppliers.

First measurable benefit: maintaining access to premium B2B markets: in tenders from major purchasing organisations (automotive, aerospace, retail, construction), SBTi commitment becomes a listing criterion, sometimes a supplier prerequisite (the SBTi Trend Tracker 2025 quantifies progress by sector). Losing a tender for lack of a validated trajectory quickly amounts to hundreds of thousands of euros in annual turnover. Second benefit: the funding premium: European banks increasingly incorporate climate trajectories in their risk assessments, and a validated target can serve as an indicator in loans whose margin depends on sustainability performance (sustainability-linked loans, Bpifrance green loans, CEE loans).

Third benefit: shared payback with regulatory obligations. Since the Omnibus I Directive, CSRD directly applies only to companies with more than 1,000 employees and €450m turnover, but the SBTi trajectory provides the climate data (ESRS E1) those customers request from suppliers, and structures responses to CDP and EcoVadis questionnaires: a single methodological investment serves multiple requests. For an SME exposed to CBAM, the SBTi trajectory mechanically makes thermal decarbonisation investments pay before free ETS allowances disappear completely in 2034. Fourth benefit: talent attraction: among engineers and senior executives under 40, SBTi commitment influences employer choice, particularly in industrial areas with recruitment shortages.

The economic risk lies in relative inaction: being the sector’s last SME without a validated trajectory when its three main customers make it a criterion.

7Key takeaways

Building an SBTi trajectory for an industrial SME is a structuring programme engaging management over 12 to 30 months, requiring strong upstream fundamentals (scope 3 Bilan Carbone, quantified reduction plan, executive committee sponsorship), and delivering a reputational asset and an industrial decision-making framework over 25 years.

Three concrete actions for the next 6 months:

• Consolidate scope 3 measurement if incomplete, targeting coverage of GHG Protocol categories 1 (purchases), 4 (upstream transport), 11 (use of sold products) and 12 (end of life).
• Map reduction levers with an order of magnitude for impact and an associated investment timetable.
• Prepare management’s decision file with explicit cost, timescale and added value.

Once these three building blocks are in place, submission is 12 months away and target publication 18 to 30 months away depending on the route chosen.

Frequently asked questions

1How much does an SBTi trajectory cost for an industrial SME in 2026?

Allow for three cost categories: SBTi validation fees (varying by profile, SME route more accessible than corporate), specialist consultancy support for modelling (€15,000 to €40,000 excl. VAT depending on scope 3 complexity), and internal team time costs (0.3 to 0.8 FTE over 12 to 24 months). The external budget, SBTi fees and consultancy, lies between €20,000 and €55,000 excl. VAT; valuing internal time brings the full investment to €60,000 to €120,000 over two financial years, excluding decarbonisation investments themselves.

2What is the difference between SBTi and CSRD (ESRS E1)?

They are distinct but converging frameworks. CSRD is a European regulatory obligation for structured climate trajectory reporting, restricted since the 2026 Omnibus I Directive to companies with more than 1,000 employees and €450m turnover. SBTi is a voluntary framework for scientific target validation. In practice, the two converge: ESRS E1 requires reporting whether the company has 1.5°C-aligned targets validated by an independent third party, and SBTi provides precisely that third party. Having an SBTi trajectory mechanically facilitates CSRD compliance.

3When should the SME route be used rather than the corporate route?

The SME route is accessible to companies below 10,000 tCO2e in combined scope 1+2, employing fewer than 250 people, with less than €50m turnover and €25m assets, outside FLAG sectors (at least 3 of these 4 criteria in addition to the emissions ceiling). In practice for a French industrial SME, this threshold is rarely met once there is a furnace, foundry or thermal process site. The SME route remains relevant for light industrial SMEs (assembly, cold plastics processing, food processing without intensive heating). Above the ceiling, the corporate route is mandatory.

4Is my existing Bilan Carbone® sufficient, and what scope 3 precision should I target?

Minimum baseline conditions: less than 24 months old, scope 1+2+3 coverage (at least material GHG Protocol categories 1, 4, 11 and 12 for an industrial SME), methodology consistent with the GHG Protocol Corporate Standard. An ADEME Bilan Carbone® is compatible but often needs reworking (2 to 4 consultant weeks) to align emission factors and boundaries. For scope 3 precision: the first submission allows spend-based estimates for general purchases, but expects physical data with a Base Empreinte® factor or EPD for main material purchases (steel, aluminium, polymers). Target coverage: minimum 67% of scope 3 for near-term targets, with a progression towards supplier-specific data.

5Can carbon credits be used in an SBTi trajectory?

The position confirmed since the April 2024 public debate: no for intermediate reductions, yes only for residual emissions under the net-zero 2050 target. In practice, the company must first reduce operational emissions by at least 90% through actual decarbonisation (efficiency, electrification, material substitution, supply chain optimisation) before considering offsetting the residual 10%. Even for that 10%, SBTi recommends high-quality credits with additionality and permanence guarantees - typically removals rather than avoidance.

6What if my sector is not covered by an SDA method?

The Absolute Contraction Approach (ACA) applies by default. For industrial SMEs not covered by SDA (assembly, furniture, plastics processing, food processing, textile processing), ACA sets a minimum 4.2%/year reduction for 1.5°C in scope 1+2 (the well-below 2°C scenario has not been acceptable for scope 1+2 since July 2022; it remains an ambition floor for scope 3). ACA also applies to scope 3 with a minimum absolute rate of 2.5%/year. If several activities coexist and only one is covered by SDA, combining methods (SDA + ACA) is both permitted and expected by the Validation Team.
