During the webinar on the SBTi Corporate Net-Zero Standard (CNZS) V2.0, we received more questions than we had time to answer—great to see so many questions! Here, we’ve compiled all the questions and answers, grouped by topic so you can jump right to the ones that are relevant to you.
These responses are based on the new CNZS V2.0 standard, published in June 2026, and on the clarifications we have received from the SBTi. Several parts of the regulatory framework are still under development, and supplementary guides and guidance are expected. Where this is the case, we have noted it in the response.

Seven changes are affecting most companies:
It is impossible to answer this question completely objectively, but we consider these to be the greatest risks and pitfalls:
The SME standard is incorporated into CNZS V2.0. Under V2.0, the distinction between SMEs and non-SMEs has been completely replaced by the classification into Categories A and B. Companies that were previously classified as SMEs are, in most cases, placed in Category B under the new framework; thus, Category B is, in practice, the successor to the SME category.
The definition is thus relatively similar, but the requirements differ. V2.0 is the only overarching framework, and the differences between Categories A and B are clearly stated throughout the document where the requirements differ. Although the requirements are not as comprehensive as those for Category A companies, Category B companies will find that the new standard imposes higher requirements than the previous SME standard did. Category B companies may find it easier to navigate the process using the standalone criteria document for Category B that SBTi published alongside V2.0.
In fact, the opposite is true. Choosing the most recent reporting year (MRY) as the base year does not imply a reset to zero. The inclusion of a third-party-reviewed assessment at the end of the cycle ensures that the targets reflect current reality and a forward-looking level of ambition.
If progress is insufficient, the targets for the next cycle are set based on a higher emissions baseline, which automatically makes the annual reduction rate steeper. There is no mechanism to reset the clock or smooth out the trajectory.
This closes a long-standing gap in accountability that existed in V1.

Goals that have already been validated remain in effect until your M5YR date or your target year, whichever comes first—provided that you do not need to recalculate your inventory or your goals before then.
If the date falls after 2028, you must use CNZS V2.0. If it falls in 2027, you may choose between V1.3.1 and V2.0.
Not immediately. However, a mandatory five-year review (M5YR) will be triggered before your target year, and during that review, you must assess your goals against the standard in effect at that time.
For M5YR targets that fall after February 2028, V2.0 is the only applicable framework. This means you will need to update your targets to meet the V2.0 requirements at that time, even if your original target year is several years in the future.
In short, yes. However, a recalculation of the base year due to structural changes or other valid reasons may trigger a recalibration and update of the targets. If this occurs after 2028 but before the mandatory five-year review (M5YR), your targets will need to be adjusted to V2.0 at that time.
In any case, we strongly recommend conducting a contingency review during the transition period to identify opportunities and risks given the new structure and the higher requirements in the objectives.
A recalculation of the base year due to significant changes in the greenhouse gas inventory (as defined in the base year recalculation policy) does not automatically trigger an update of the targets. Instead, it triggers a recalibration—the step in which the targets are assessed against the revised inventory and the criteria used in the validation process to determine whether an update to the targets is necessary.
If you update your targets before February 1, 2028, your company can choose between Version 1.0 and Version 2.0 of the standard. After February 1, 2028, Version 2.0 will be mandatory.
Changes to the standard never take effect immediately, and older versions are phased out gradually, giving companies plenty of time to adjust.
If you switch to V2.0 before the target year, as in your example, you have the option to choose a shorter period than the prescribed five years for the first target cycle. This is C9.2(a), and it is entirely voluntary. If your company chooses this option, you can set a shorter transition target. Otherwise, C9.2(b) applies.
For all subsequent target cycles, C9.2(b) applies as the standard, which means that the targets must span five years.
The same answer as above.
The submission date determines which standard applies. You may submit your work according to V1 in January 2027.
The SBTi Corporate Net-Zero Standard is the global framework for how companies set science-based climate targets—that is, targets aligned with what climate science requires to limit global warming to 1.5°C. To date, over 11,000 companies worldwide have set targets within the SBTi framework. Version 2.0 is a direct response to ten years of experience, consultations, and pilot tests, and represents one of the most important climate policy documents for the business world in 2026.
More details regarding the framework for third-party recognition of commodity certificates will be provided in the near future.
Projects and market instruments are valid tools for implementing and monitoring targets, provided they meet the integrity criteria set forth in the standard. They remain valid throughout the entire target cycle, including under any legacy provisions where applicable.
The mechanism is essentially the same. A certificate representing the environmental attributes of the biogas is transferred and canceled to substantiate a claim.
For electricity EACs, there is now an established framework based on “near,” “new,” and “now”: “near” refers to the delivery region, “new” refers to the age of the production facility, and “now” refers to hourly or annual matching. Corresponding criteria for biogas are expected in Q4 2026.
Book-and-claim and mass balance instruments are not categorically excluded, but must meet the integrity criteria and be reported separately from the physical greenhouse gas inventory. A company cannot offset biogas credits against physical Scope 1 emissions—they are reported separately, as a system contribution.
EACs are not being eliminated, but their role is changing. Under V2.0, they serve as an execution tool within the implementation hierarchy rather than an accounting mechanism, and they are reported separately from the physical inventory instead of being offset against it.
To be valid, e-EACs (certificates of origin) must meet three criteria:
The requirements will take effect when V2.0 opens for validation on February 1, 2027. Long-term market instruments such as PPAs, VPPAs, and multi-year certificate agreements signed before that date are covered by so-called “legacy protection” for the remainder of the agreement’s term. Short-term and ongoing spot purchases of unallocated EACs are not covered by this provision. Detailed guidance for electricity is expected in Q4 2026, and corresponding criteria for other commodity certificates during the same period.
A noteworthy update: Version 2.0 explicitly allows the same tools used for Scope 2 to also be used for electricity in the value chain—that is, electricity that falls under Scope 3, such as in purchased goods and services or in the use of sold products. Both independent EACs and (virtual) PPAs are approved instruments. Where you know where the electricity is consumed, the matching must take place within the same supply region. Where the location is unknown, the activity pool may be defined more broadly, for example, nationally or regionally.
Under V2.0, the ambition level for Scope 2 is anchored in the physical inventory, while market-based instruments are used as implementation tools and reported separately.
Whether certificates for low-emission district heating (such as from waste heat or renewable sources) will qualify as approved market instruments under the implementation hierarchy depends on the upcoming guidance on commodity certificates and on the framework for third-party verification. Both are expected in Q4 2026.
We will provide further details on the exact procedure once the SBTi has published its guidance. Until then, it should be safe to purchase market-based instruments, as long as they meet the integrity criteria.
A clarification is needed here. Companies with a projected annual increase in electricity consumption of more than 20% must use the absolute emissions reduction method. For all others, there are still two options for Scope 2 targets under V2.0: absolute emissions reduction, based on the physical location-based inventory, and an LCE alignment target based on an increased share of low-carbon electricity.
Companies that opt for absolute reduction may still use RECs, PPAs, and other qualifying market instruments as mitigation measures within the implementation hierarchy. The difference is that these are reported separately from the physical inventory rather than being offset against it.
RECs and guarantees of origin will not disappear, then. They will shift from being an accounting mechanism to being an implementation mechanism—a difference that is both significant and easy to overlook.
Yes, and this is one of the more business-critical changes to reporting in V2.0.
The standard clearly states that measures and their results must be reported based on the level in the implementation hierarchy to which they belong, and that measures at the activity pool and sector levels must be reported separately from the physical greenhouse gas inventory. They must not be offset against it. Measures at the activity level that reduce the physical inventory support claims of emission reductions. Measures at the activity pool and sector levels that are not reflected in the physical inventory support only claims regarding system contributions.
Mixing these together in reporting would allow a company to overstate its direct emissions reductions—which is exactly what the separation requirement is designed to prevent.

For Category A companies, all Scope 3 categories that individually account for more than 5% of total Scope 3 emissions must be subject to targets. This is a higher threshold than the previous coverage threshold of 67%.
In addition, emissions-intensive activities (EIA) in the value chain must be identified during target validation and disclosed publicly in the subsequent reporting cycle. Companies must also actively engage with suppliers and customers as part of their implementation efforts.
The supplier alignment target (formerly known as the engagement target) carries over into V2.0 as a valid option for Scope 3 targets, so existing engagement targets can be mapped over.
In the long term, for category-specific emissions, the parties in the value chain will need to achieve residual levels themselves—not merely set scientific climate targets—in order for long-term alignment goals to be achieved.
There is no general coverage percentage for Scope 3 in V2.0. Instead, Category A companies are only required to include material Scope 3 categories and emission-intensive activities (EIA). These are defined as categories that account for 5% or more of total Scope 3 emissions.
Based on SBTi’s research and analysis, this generally corresponds to 80–85% coverage of Scope 3, which is higher than the current standard’s threshold of 67%.
The SBTi is developing an Interoperability and Recognition Framework and is expected to begin publishing guidance starting in Q4 2026. The framework will establish criteria and processes for recognizing third-party tools and certification frameworks across several categories, including technical tools, electricity certificates, commodity certificates, and carbon credits. It is not yet clear whether and how the framework will address the recognition of science-based standards at the supplier level.
Based on the general direction of the standard, we can say that, in order to be considered “in transition,” a supplier must demonstrate progress toward a science-based target—and that the SBTi’s own validated targets are the clearest path to achieving this. Whether targets validated under other frameworks will be formally recognized as equivalent is precisely the type of question the interoperability framework is intended to answer.
Yes, the concept carries over. The “supplier alignment target” in V2.0 is the same concept as the previous “supplier engagement target”: a goal to increase the proportion of Tier 1 suppliers—measured by emissions or purchase value—that are in the process of transitioning or are net-zero compliant. Your existing target can be mapped to the V2.0 methodology.
The most important difference is that the long-term alignment targets in V2.0 require suppliers to have actually achieved residual levels, not merely to have set a scientific climate target. The ultimate ambition is therefore higher for long-term targets set in a new cycle.
Supplier alignment targets provide continuity for companies that had a supplier engagement target during V1. Since all targets a company sets must be forward-looking in their ambition, you are required to report the results against the previous target as part of your reporting.
Two upcoming resources—“Methods, Metrics, and Pathways” and “SBTi Assurance Framework”—which are expected to be published starting in Q4 2026, will provide greater clarity on the specific technical details.
The same answer as above.
See the answer below.
Whether a category is included in the scope of the short-term target depends on materiality. If your company excludes commuting from the five-year target, this should mean that the category accounts for less than 5% of total Scope 3 emissions. However, Scope 3 categories that account for 5% or more of emissions are reassessed for each new base year during each target validation. It may very well be the case that as emissions decrease in today’s dominant categories, the share of other categories rises above the 5 percent threshold, and they must then be included in the scope of the short-term target for the next target cycle. Important to note: if a category’s share rises above the 5 percent threshold midway through the cycle, as a result of reductions in other categories, this does not mean that the category must be added to the short-term target midway through the cycle.
Long-term targets are voluntary for Scope 3, but if your company chooses to set them anyway, they must cover all Scope 3 emissions. The exceptions available for short-term targets do not apply to long-term targets.
OER is a framework within SBTi v2.0 that governs how companies take responsibility for ongoing emissions while working toward net-zero. Important to understand: OER is not a way to exclude emissions from climate targets. It is a separate track—and a complement to the reduction targets—that measures ongoing responsibility.
Carbon credits cannot be counted toward Scope 3 targets. Emissions reductions in the value chain must be achieved through actual measures, and credits are excluded from the greenhouse gas inventory.
In V2.0, for the covered Scope 3 emissions, SBTi grants recognition under Ongoing Emissions Responsibility (OER). OER covers remaining Scope 1, 2, and 3 emissions during the target cycle and has three levels:
Starting in 2035, Category A entities will be required to offset at least 1% of their Scope 1–3 emissions through carbon sequestration, a percentage that will increase linearly to 100% by the net-zero year. For long-lived greenhouse gases, at least 10% of that portion must be offset through long-term sequestration, which will also increase to 100%.
It is important to distinguish between two things: credits purchased under the OER are reported separately from the inventory and must not be presented as emission reductions. Furthermore, the same credits cannot be double-counted toward both OER recognition and the mandatory removals requirement after 2035.
In practice, this means th carbon offsetting s outside the value chain are given a clearly defined role in the standard.
At zeromission.se/resurser, we share a separate resource document—available for free download—that specifically addresses how companies can communicate their use of carbon credits.
Credits purchased under the OER are completely outside the scope of the physical greenhouse gas inventory and cannot be used to claim emission reductions toward Scope 1, 2, or 3 targets.
What a company can claim is recognition at the relevant OER level (Engaged, Advanced, or Leadership) once the SBTi has confirmed this at the end of the target cycle.
The SBTi Claims Policy is a separate resource, still under development, with publication planned for early 2027. It will define exactly how this may be communicated externally.
Yes. Reported emissions from all Scope 3 sources will be included in the calculation of the mandatory target, even if a category is not included in the near-term target.

The question leaves room for interpretation, but provides an opportunity to highlight internal governance.
As a general principle, CNZS V2.0 requires that objectives be approved and monitored at the highest level of governance (board of directors or equivalent), with supporting governance structures in place to ensure their implementation.
Responsibility for annual reporting and for the assessment at the end of the target cycle should therefore rest with senior management, with operational input from the sustainability and finance functions.
There is no direct connection or interoperability between CNZS V2.0 and ESRS.
The SBTi does not require compliance with the ESRS. However, compliance with the ESRS can fulfill parts of the SBTi’s transition plan requirements, provided the right components are included.
CNZS V2.0 has been developed in close coordination with the GHG Protocol, particularly in two areas: time-matching of Scope 2 emissions and the use of market instruments. The standard includes provisions specifically intended to align with the upcoming GHG Protocol guidance, “Actions and Market Instruments (AMI),” particularly regarding the reporting of market instruments and project-based measures separately from the physical inventory.
However, the SBTi makes no assumptions about the outcome of the GHG Protocol’s revision process. None of the standard’s criteria should be interpreted as an indication of, or an assumption regarding, where the GHG Protocol’s guidance will ultimately land. Any targeted changes to reporting aspects in CNZS V2.0 will be considered only after the GHG Protocol’s revision is complete.
Category A companies must ensure an audit—at a minimum at the “limited assurance” (limited assurance)—which covers Scope 1, Scope 2, and Scope 3 emissions for the target’s base year, calculations of low-carbon emissions, emissions from material emission-intensive activities, and other metrics used in setting the target.
The SBTi has not yet decided whether to maintain a “registered list” of verification providers. Instead, the SBTi will develop criteria and processes for recognizing third-party frameworks, standards, and programs, where applicable. Where no recognized framework is available, the SBTi’s Assurance Framework will define the scope of the assurance work to be performed by the third-party assurance provider.
Version 2.0 explicitly requires that the goals be approved at the board level, which means that senior management still needs to be present. Frame the initial discussion around risk management and strategic positioning—transition risks and demands from customers and procurement agencies are terms that boards respond to.
Practical arguments for internal buy-in:
For the CFO specifically, the internal carbon pricing mechanism under OER is a useful starting point. It translates the emissions profile into a financial figure, making the investment calculation for emissions reductions concrete and comparable to other capital allocation decisions.
The honest truth is that the process is more demanding in V2.0 than it was before. Starting data collection early and getting the governance in place is the single most important thing a first-time company can do.
Companies that wish to set goals in accordance with the new standard can no longer follow industry guidelines and standards published prior to CNZS V2.0.
All industry guidance and industry standards will be revised to be compatible with CNZS V2.0. Once the applicable industry-specific guidance or standard is published, it may, in some cases, take precedence over CNZS V2.0—in which case, this will be specified in the documentation.
