In January 2026, SBTi announced the milestone of 10,000 companies with validated targets: a clear signal that SBTi Science Based Targets initiative companies how to join climate targets is no longer a “best-in-class” curiosity, but a requirement that is increasingly showing up in procurement, tenders, and supply-chain ESG scorecards. If you work in a B2B SME, the typical question is straightforward: “How do I join and get targets validated that will stand up to due diligence and audits?”
What SBTi is and why it’s now the reference standard for corporate climate targets
SBTi is a framework with technical criteria and a third-party validation process (via SBTi Services) for “science-based” climate targets—i.e., aligned with pathways to limit global warming (notably 1.5°C). The practical difference is that you’re not just stating an intention: you’re adopting verifiable rules on boundaries, coverage, and methods.
The B2B distinction that matters is:
- Commitment: the company publicly declares it intends to set SBTi targets.
- Targets validated: the targets have been assessed and approved against SBTi criteria.
Validation reduces greenwashing risk in claims to customers and investors, because it makes it harder to “choose” convenient boundaries or exclude relevant parts of the value chain.
SBTi is also a “common language” across sectors. Procurement teams can compare different companies using a similar grid: scope coverage, base year, methods, and time horizon ambition.
Near-term vs net-zero: two different levels, not interchangeable
Near-term targets are the operational horizon. Typically we’re talking 5–10 years: budgets, capex, energy efficiency, electrification, supplier engagement.
Net-zero targets are the long-term architecture. This is where rules on residual emissions and the role of removals come in—without confusing “net-zero” with generic offsetting.
Why now (operational box)
Pressure has increased for two very concrete reasons:
- Mass adoption: more companies with validated targets means more downstream requests to suppliers.
- Data quality: credible targets require more robust GHG inventories, especially for Scope 3. This affects ERP, energy data, LCA/EPD, and supplier engagement processes.
Sources: SBTi “Companies taking action”; SBTi Criteria (PDF).
Which companies can join SBTi and what prerequisites you need (data, boundaries, governance)
The prerequisite that most often blocks validation is one thing: a GHG inventory that is not consistent with the GHG Protocol or has boundaries that cannot be traced. Before talking about targets, you need to get “what you’re counting” in order.
“Hard” prerequisites on data and boundaries
At a minimum you need:
- A GHG inventory compliant with the GHG Protocol (minimum boundaries).
- Definition of organizational boundaries (control approach or equity share).
- A single, consistent base year across scopes, with traceability of calculations (audit trail).
If accounting isn’t aligned, validation can stall or require rework.
Coverage, materiality, and limits on exclusions
Here SBTi is very clear:
- If Scope 3 is ≥ 40% of total emissions, it must be included in near-term targets.
- Scope 3 targets must cover at least 67% of Scope 3 (with limited exclusions).
- You cannot exclude more than 5% of Scope 1+2 and no more than 5% of Scope 3.
This answers the typical buyer question: “Can we leave out the difficult categories?” In general, not beyond those limits.
Governance: who really needs to be involved
Governance is a practical requirement, not an org-chart exercise:
- Internal ownership: often the CFO (numbers, controls) and CSO/sustainability lead (methods, roadmap).
- Data controls: audit trail, versioning, recalculation policy.
- Scope 3 accountability: procurement, quality, R&D, logistics.
- Claims and communications policy: avoid mismatches between marketing and SBTi targets.
B2B examples: why the data and functions involved change
- Manufacturing: Scope 3 is often dominant (raw material purchasing, inbound/outbound transport, product use). Procurement and R&D become central.
- Services/IT: more weight on Scope 2 (offices, data centers, electricity). Energy management and IT/data are decisive.

How to join SBTi step by step: commitment, pathway choice, and submission for validation
The operational side is more straightforward than it looks—if you come in with your data ready.
Step-by-step (real process)
- Registration on the SBTi Services Validation Portal
- Choice: commit or submit directly
- Preparation: submission form + tool/methodology
- Contract and fee
- Interactions with the validator and responses to clarification requests
- Publication of approved targets
Source: SBTi FAQ.
Reputational rule: 24 months after the commitment letter
After the commitment letter, the company has 24 months to submit targets for validation. If it doesn’t, the status may show as “Removed” on the Target Dashboard. In a tender, this can become a bigger issue than not joining in the first place.

Choosing the right pathway
The typical choice is:
- Near-term only
- Near-term + net-zero
If the company is eligible as an SME, there is a pathway with a dedicated checklist and more manageable requirements for an SME (including fees). Check eligibility and required documents before setting up the project.

Best practice: the “data pack” first
Reduce back-and-forth with SBTi Services by preparing a single package:
- inventory and boundaries
- Scope 3 mapping by category
- methods and assumptions
- notes on exclusions and coverage
An internal “validation” (a red-team style review) before submission helps avoid delays.
Micro B2B example (typical)
An automotive supplier receives an OEM request: it makes a commitment immediately to send a signal to procurement, then plans 6–12 months to consolidate priority Scope 3 (e.g., Cat.1 purchases and Cat.4 transport) and define aligned targets.
At this stage it helps to repeat the SEO question coming from the business: SBTi Science Based Targets initiative companies how to join climate targets mainly means “how not to waste time on rework.”
How to set SBTi targets for Scopes 1, 2, and 3: methods, criteria, and common mistakes to avoid
The key point is coverage. If Scope 3 is material, you can’t treat it as an appendix.
Technical criteria to keep on the table
- Scope 3 is mandatory in near-term targets if ≥40% of the total.
- Scope 3 coverage ≥67% of Scope 3 emissions (considering reported + excluded).
- Maximum exclusions: 5% for Scope 1+2 and 5% for Scope 3.
Source: SBTi Criteria (PDF).
Methods and approaches (terms you’ll encounter)
- Absolute contraction approach: absolute emissions reduction.
- Sectoral decarbonization approach (SDA): alignment to sector pathways where applicable.
- Supplier engagement target: useful when Scope 3 dominates and the lever is getting suppliers to set targets.
- Separate targets for material categories (when it makes sense for clarity and management).
Common mistakes that cost weeks
- Intensity targets used where they are not allowed or not suitable for the specific case.
- Inconsistent base year across scopes or unmanaged recalculations.
- Underestimating Scope 3—especially Cat.1 Purchased goods and services—and then having to redo everything.
- Exclusions beyond 5% that make the target non-compliant.
Source: SBTi Criteria (PDF).
Scope 2: market-based vs location-based (and what changes in the energy strategy)
The distinction directly affects levers such as:
- energy contracts, PPAs
- certificates (GOs/RECs) and how they’re managed
- data granularity
As a market trend, there is discussion of a possible tightening toward approaches closer to “real-time alignment.” Treat it as a direction of travel, not a definitive requirement today.

Box: offset ≠ SBT
Carbon credits do not replace SBTi reduction targets. If you use them for claims, they must sit in a logic separate from target compliance, and they must not cover up a lack of decarbonization.
This is a point that often comes up in the query SBTi Science Based Targets initiative companies how to join climate targets: joining doesn’t mean “offsetting,” it means reducing under clear rules.
How much it costs and how long it takes: timelines, fees, internal resources, and consulting
Timelines depend more on data maturity than on filling out forms.
SBTi Services validation timelines (SOP figure)
- Corporates: 40–60 business days from the validation start date (depending on the service)
- SME: ~21 business days estimated
Source: SOP Target Validation (SBTi Services, January 2026).
Fees (SME checklist figures)
For SME-eligible companies:
- $1,250 for near-term or net-zero “only”
- $2,500 for near-term + net-zero The checklist notes these are reduced fees compared to standard fees of $9,500+ (plus VAT where applicable).
Source: Target Validation Application Checklist for SMEs (October 2024).
End-to-end timelines (realistic, depend on complexity)
- 8–16 weeks for a Scope 1+2 inventory in “data-ready” companies
- 3–9 months if Scope 3 requires supplier data collection
Useful milestones: data readiness → target model → submission → clarifications → approval → publication.
Typical internal resources
You almost always need:
- sustainability lead
- energy manager
- controlling
- procurement
- IT/data (bills, meters, travel, spend mapping)
- legal/comms for claims and disclosure
When consulting makes sense
It makes sense when:
- you’re in sectors with specific standards (e.g., FLAG, power, buildings, automotive)
- you have M&A and base-year recalculations
- you want to reduce rework before submission

What happens after approval: monitoring, reporting, updates, and the role of carbon credits and offsetting
After approval, the most
Key rule: review at least every 5 years
There is an obligation to review at least every 5 years. The “trigger date” matters: from that point the company must conduct the review, submit results and, if necessary, update targets.
Source: SBTi guidance on five-year target reviews.
Example timeline (from SBTi guidance)
- Targets validated March 2021
- Review trigger: end of March 2026
- Submit results: by end of September 2026
- If an update is needed: submit new targets by end of March 2027
Source: SBTi blog on five-year target reviews.
Internal MRV: what to set up
You need practical MRV:
- monthly or quarterly KPIs
- data quality checks and audit trail
- recalculation policy (structural changes, methodologies)
- alignment with corporate reporting and customer requests (without making unverified legal claims)
Carbon credits and offsetting: where they fit (and where they don’t)
SBTi is centered on reductions. Credits can come in as “beyond value chain” action or to neutralize residual emissions in coherent approaches—especially when talking about high-integrity removals. They must not become the way to avoid action on energy, processes, and the supply chain.
Minimum checklist for procurement of credits (if you use them for extra claims):
- standard and registry
- vintage and retirement rules
- additionality
- reversal risk and permanence management
- geographic and sector alignment, when relevant
Tokenization: useful for traceability, not for “doing SBTi”
Tokenization can help with audit trail and traceability, for example:
- serialization and linkage to a registry
- on-chain retirement and proof-of-retirement
- supplier portal with verifiable attestations of credits retired for extra claims
It does not replace SBTi requirements on inventories, boundaries, and targets. It supports transparency, not an alternative to validation.
B2B commercial impact
Staying “active” on the dashboard and meeting review/update requirements reduces reputational risk and helps with customer requests. Conversely, a status change due to non-compliance can weigh on tenders and renewals.
