June 12, 2026
At the half-year mark, it has already been a marathon year for those keeping pace on climate standards and guidance, from the Greenhouse Gas (GHG) Protocol’s proposed guidance overhaul, AIM Platform releasing their V.1 Standard & Guidance, and the heavily anticipated Science Based Targets initiative (SBTi) Corporate Net-Zero Standard (CNZS) V2.0, released on June 11.
With SBTi’s largest revision to their Standards to date, the signal to the 11,000+ companies with targets and those considering targets is clear: focus on real, measurable emissions cuts, with growing recognition for the work companies do inside their own value chains. The ripple effects reach well beyond the companies that hold targets: their customers and suppliers now have new tools at their fingertips to pursue decarbonization, and it is in everyone’s interest to see the opportunity this creates across the value chain.
For companies investing in value-chain decarbonization such as insetting, this clarity is exactly what ClimeCo and other leaders in the space advocated for, empowering companies to act with confidence. The new Standard is anchored in commercial and geopolitical reality, recognizing that companies do not control everything in their value chains and shaping its target-setting and performance guidance to reflect that challenge. CNZS V2.0 puts value-chain action and market-based instruments at the center of how a company is expected to deliver on its target. It moves the central question from Can I do this? to Here’s how it counts.
Below is ClimeCo’s expert analysis of where the final Standard landed on the issues that matter most, including where it reflects feedback we offered during the second public consultation.
Timing Matters More Than Ever: Accelerated Implementation
The big news on timing: SBTi pulled implementation earlier than the late-2025 draft signaled. V2.0 takes effect February 1, 2027, with submissions accepted from the first quarter of 2027. Just as important, companies with existing validated SBTs do not have to wait; they can already use the mechanisms allowed under CNZS V2.0, such as market-based instruments, to show progress toward their current targets. The companies that prepare now will be best positioned when V2.0 becomes the default.
Scope 3 and Market-Based Mechanisms Gained Clearer Standing, for Now
This is the headline for anyone investing in reducing value-chain emissions (insetting): market-based instruments can be used to show progress toward science-based targets. Chapter 4 outlines an implementation hierarchy that prioritizes direct emissions reductions at the source, then activity-pool actions, then sector-level actions where direct decarbonization is not feasible. Market instruments like energy attribute certificates (EACs) can support action at both the activity-pool and sector levels. This is what ClimeCo has advocated for all along, because market-based instruments connect supply and demand for emission reductions and let both scale as fast as possible.
Pragmatism by Design
Companies who already have validated SBTs will be allowed to use market instruments to show progress toward their targets. In a notable change, market instruments have only a 12-month temporal alignment window (down from 24 months in the late-2025 draft CNZS), though there is flexibility if justified by longer production cycles, storage periods, or product lifespans.
Stepping into new and helpful territory, SBTi also acknowledges and allows co-claiming – for example, a brand and a retailer both claiming Scope 3 reductions from one intervention at an upstream supplier. This kind of value chain collaboration is what Scope 3 was designed to incentivize.
Start Now, Not Later
Under R27.1, SBTi recommends that companies acquire market instruments progressively across the target timeframe rather than deferring purchases to the end, unless supply constraints or market availability prevent it. In other words, build a steady, credible procurement strategy now rather than wait.
Scope 2 Remains Flexible
On Scope 2, V2.0 preserved the flexibility ClimeCo advocated during the open response period, with deliverability-region requirements, including practical exceptions, such as interconnection rights and aggregated multi-region contracts. Hourly matching functions as a reporting and recognition mechanism rather than a barrier to entry. Companies retain room to build procurement strategies that work in the real world.
Ongoing Emissions Responsibility (OER) Program Is Official
The OER program is where CNZS V2.0 finally puts the voluntary carbon market on the record. It offers three recognition levels – Engaged, Advanced, and Leadership – up from two tiers in the late-2025 draft. Eligible contributions include emissions reductions and carbon removals, and remain optional until 2035, after which Category A companies must procure eligible carbon removals.
Credible Third-Party Integrity
One of the most consequential commitments in the new Standard is SBTi’s pledge to recognize credible third-party integrity frameworks. It means high-integrity instruments validated against trusted external criteria can be counted with confidence, and book-and-claim approaches now have the clearest standing they have ever had.
Interoperability on The Horizon
Encouragingly, the GHG Protocol’s recent AMI whitepaper suggests companies will be able to report actions that the SBTi now says count, which means the accounting and reporting pieces are beginning to align with the same logic.
The work now is translating that signal into credible low-carbon transactions: identifying where value-chain action is possible, choosing high-integrity instruments, executing, then sharing and celebrating real, measurable progress.
