TL;DR: The Science Based Targets initiative (SBTi) is the global standard-setter for corporate climate targets aligned with the Paris Agreement 1.5°C pathway. As of early 2026, more than 10,263 companies have validated targets and the SBTi is finalising its Corporate Net-Zero Standard Version 2.0, mandatory for all new submissions from 1 January 2028. Net0, an AI infrastructure company serving governments and global enterprises, automates the greenhouse gas inventory, target-setting, scenario planning, and disclosure workflows that SBTi validation now demands.

Key Takeaways

• 10,263 companies had fully validated SBTi targets by February 2026, collectively representing approximately 40% of global market capitalisation, according to the SBTi Target Dashboard and SBTi Trend Tracker 2025.

• Validated near-term targets grew 40% (from 6,954 to 9,764) and net-zero targets grew 61% (from 1,441 to 2,325) in 2025, per the SBTi Trend Tracker 2025.

• The second consultation draft of the Corporate Net-Zero Standard V2.0 was released in November 2025. V1.3 remains valid for new submissions until 31 December 2027; V2.0 becomes mandatory from 1 January 2028.

• V2 introduces cyclical validation (Entry Check → Initial Validation → Renewal Validation), a mandatory transition plan within 12 months of initial validation for Category A companies, and a new Ongoing Emissions Responsibility framework replacing Beyond Value Chain Mitigation.

• SBTi targets are now embedded in mandatory disclosure regimes including the EU CSRD / ESRS E1 and California SB 253, raising the compliance stakes for multi-country enterprises.

What the Science Based Targets Initiative Is in 2026

The Science Based Targets initiative is a global standard-setting body that validates corporate greenhouse-gas reduction targets against the science required to hold warming to 1.5°C. It was founded in 2015 by the CDP, the UN Global Compact, the World Resources Institute, and WWF. SBTi does not issue regulation: it sets criteria, runs validation, and publishes a public register of approved targets.

Over a decade on, SBTi validation has become the default benchmark for investor-grade climate commitments. The Reuters coverage of the April 2026 Trend Tracker confirmed that the cohort of validated companies is now large enough that SBTi data sits inside ESG ratings, lender covenants, and procurement questionnaires. SBTi exclusively recognises real reductions: offsets and avoided emissions cannot count toward near-term targets, though a separate removals requirement applies at the net-zero target year.

SBTi Adoption Growth and Regional Leaders

SBTi adoption accelerated through 2025 and into early 2026. Net0's analysis of the SBTi Trend Tracker 2025 and related dashboard data shows three patterns.

• Overall scale: 10,263 companies with fully validated targets and 12,882 with either validated targets or active commitments as of early 2026.

• Net-zero momentum: validated net-zero targets rose from 1,441 to 2,325 over the course of 2025 — a 61% year-on-year increase driven largely by companies anticipating the V2 transition.

• Regional concentration: Japan leads with 2,091 validated companies, followed by the United Kingdom (1,363) and the United States (943). Healthcare, Information Technology, and Materials were the fastest-growing sectors proportionally.

This concentration matters for enterprise buyers. When 40% of global market capitalisation has a validated target, suppliers without one increasingly fall below procurement and financing thresholds. Net0's analysis of Scope 3 disclosure pressure covers how this cascade reaches into the supply chain.

The SBTi Corporate Net-Zero Standard V2.0

The Corporate Net-Zero Standard V2.0 is the most significant revision the SBTi has released since its original 2021 net-zero framework. The first public consultation draft appeared in March 2024; the second consultation draft was published on 6 November 2025 and is being finalised for publication during 2026.

Two dates define the transition. Companies can continue to submit new targets under the existing Corporate Net-Zero Standard V1.3 and Near-Term Criteria V5.3 until 31 December 2027. From 1 January 2028, all new submissions must use V2.0. Existing validated targets remain valid for the duration of their target timeframe.

V2 introduces a new company categorisation system that determines which requirements apply, per the V2.0 executive summary:

• Category A: large companies, plus medium-sized companies in high-income countries — typically those with more than $450 million turnover or assets and more than 1,000 employees.

• Category B: medium-sized firms in lower-income categories, plus all small and micro-sized companies.

Only Category A companies must meet the most demanding V2 provisions, including mandatory climate transition plans and limited assurance on emissions data.

Cyclical Validation: A Continuous-Improvement Model

The defining structural change in V2 is the move from a one-time validation to a three-stage cyclical process. Under V1.3, a company submitted its target once and the target stood for its full timeframe. Under V2, targets are reviewed and refreshed on a cycle to keep pace with evolving science and company circumstances.

The three stages work as follows:

1. Entry Check confirms company eligibility, the organisational boundary of the inventory, and readiness to submit. This replaces the old "commit" letter.

2. Initial Validation is where the target pathway is approved. For Category A companies, this also triggers two new obligations: a climate transition plan published within 12 months of initial validation, and limited assurance on Scope 1, Scope 2, and material Scope 3 categories.

3. Renewal Validation reviews actual progress against the target, recalibrates the pathway where required, and extends validation for the next cycle.

For practitioners, the implication is clear: SBTi validation is no longer a one-off project. It becomes an ongoing programme that requires a defensible, auditable carbon accounting process running continuously in the background.

Scope-Specific Target Requirements Under V2

V2 abandons the single uniform target-setting method in favour of scope-specific pathways, giving companies more flexibility on Scope 1 while tightening Scope 2 and Scope 3 requirements.

Scope 1. Companies can choose from three methods: a linear reduction pathway to net-zero, a pathway based on increasing the share of low-carbon activities, or an Asset Decarbonization Plan (ADP) that uses a company-specific carbon budget tied to asset retrofit schedules and technology readiness. The ADP route is the most significant departure from V1.3 and is intended for heavy-industry sectors where site-by-site investment cycles dictate the realistic pace of change. Net0's decision-making framework for decarbonization initiatives walks through how to sequence asset-level interventions against a carbon budget.

Scope 2. V2 requires 100% low-carbon electricity by 2040, defined as electricity with an emissions intensity of ≤0.024 kg CO₂ per kWh, per the V2 second consultation draft. Geographic matching becomes mandatory, and hourly matching is phased in for the largest consumers first. This pulls Scope 2 target-setting closer to the physical reality of the electricity grid and away from annual certificate-only claims.

Scope 3. The previous rule of thumb — that targets must cover at least two-thirds of Scope 3 emissions — is replaced by a cleaner test: targets must cover all Scope 3 categories representing 5% or more of the total footprint. Three target-setting methods are permitted: emissions intensity, activity alignment, and counterparty alignment. The shift rewards companies that have invested in granular Scope 3 measurement and supplier engagement, because the new methods require category-level accuracy rather than the blended intensity metrics many companies still rely on.

Ongoing Emissions Responsibility Replaces BVCM

V2 replaces the voluntary Beyond Value Chain Mitigation (BVCM) concept with an Ongoing Emissions Responsibility (OER) framework. The shift, detailed in independent analysis by NewClimate Institute and Watershed, introduces two tiers through 2035 and becomes mandatory for Category A companies afterwards.

• Recognised (voluntary, until 2035): companies address at least 1% of their ongoing emissions through beyond-value-chain action.

• Leadership (voluntary, until 2035): companies address 100% of their ongoing emissions.

• Mandatory (post-2035): Category A companies assume responsibility for an increasing share of ongoing emissions, scaling to 100% by the net-zero target year.

At the net-zero target year, companies must also neutralise all residual emissions, with at least 41% of neutralisation delivered through long-lived carbon removals (as opposed to nature-based sequestration or avoided-emissions credits). This is a stricter quality bar than most corporate net-zero programmes use today and closely tracks the specifications of high-integrity carbon removal credits.

How SBTi Aligns with CSRD, ISSB, and California SB 253

SBTi targets are increasingly referenced inside mandatory climate disclosure regimes, which turns a voluntary commitment into a de-facto compliance asset.

• EU CSRD and ESRS E1: companies subject to the Corporate Sustainability Reporting Directive must disclose transition plans, targets, and measurable reduction pathways. A validated SBTi target substantially satisfies the target-disclosure component of ESRS E1 and is explicitly recognised in the EFRAG implementation guidance.

• ISSB IFRS S2: IFRS S2 requires disclosure of climate-related targets, their basis, and progress. A validated SBTi target provides an externally-reviewed reference point that auditors and ratings agencies can test against.

• California SB 253 and SB 261: California's Climate Corporate Data Accountability Act requires large companies doing business in the state to disclose Scope 1, 2, and from 2027, Scope 3 emissions. A validated target aligned with 1.5°C signals governance quality during the first reporting cycle.

• UK and Japan: the UK's SECR regime and Japan's TCFD-mandated disclosures both treat SBTi validation as acceptable evidence of credible climate strategy.

For multi-country enterprises, this regulatory convergence changes the calculus. A single SBTi target, well-maintained, can substitute for target-setting exercises under four or five reporting regimes.

The Strategic Case for SBTi Targets in 2026

The strategic reasons to validate under SBTi in 2026 are different from those in 2021. Early adopters chased reputation; today's adopters chase risk management, capital access, and supply-chain continuity.

• Regulated disclosure. Mandatory regimes including CSRD, ISSB, SB 253, and emerging rules in Brazil, Singapore, and Australia all reference science-based pathways. A validated target converts disclosure from a drafting exercise into a data-publication exercise.

• Capital access. ESG-linked lending, sustainability-linked bonds, and green-loan pricing tiers frequently cite SBTi validation as a condition. The CDP 2024 finance analysis showed that validated-target companies faced materially lower sustainability-linked financing spreads.

• Procurement thresholds. Major customers — Unilever, Walmart, Microsoft, Apple — use SBTi validation as a tier-one screening criterion for strategic suppliers. Exclusion from these tiers now carries revenue consequences, not just reputational ones.

• Operational discipline. The internal rigour required for validation — a complete GHG Protocol-aligned inventory, documented methodology, forward-looking scenario plan — drives measurable operational improvements that show up in energy spend and profitable decarbonisation outcomes.

• V2 readiness. Companies that validate under V1.3 before the 2027 deadline buy themselves time to build the inventory quality, assurance processes, and transition plan infrastructure that V2 will formally require.

How Net0 Supports SBTi Target Setting and Validation

Net0 is an AI infrastructure company that builds AI solutions for governments and global enterprises. Its sustainability vertical delivers the ingestion, calculation, scenario, and disclosure layers required to design, validate, and maintain SBTi-aligned targets across the full cycle.

• Automated inventory. Net0 ingests data from over 10,000 enterprise systems and applies 50,000+ emission factors to produce a GHG Protocol-aligned inventory covering Scope 1, 2, and all 15 Scope 3 categories.

• Scope 3 at supplier resolution. Net0's AI-driven data collection for Scope 3 replaces spend-based estimates with activity-level data — directly aligning with V2's emphasis on category-level coverage and the activity-alignment and counterparty-alignment methods.

• Scenario modelling. Net0's Marginal Abatement Cost Curve analysis and scenario simulators translate SBTi pathways into company-specific investment plans, supporting the Asset Decarbonization Plan route under V2 Scope 1.

• Transition-plan and assurance readiness. Net0 produces auditable records, methodology documentation, and disclosure-ready outputs that support the limited assurance requirement for Category A companies under V2.

• Multi-framework alignment. The same dataset produces CSRD, ISSB, CDP, SB 253, and SBTi submissions — reducing duplication across 30+ reporting frameworks.

Frequently Asked Questions

What is the Science Based Targets initiative (SBTi)?

The SBTi is a global corporate climate action organisation, founded in 2015 by CDP, the UN Global Compact, WRI, and WWF, that validates company greenhouse-gas reduction targets against the latest climate science. It sets criteria aligned with the Paris Agreement 1.5°C pathway and maintains a public register of validated targets.

When does the SBTi Corporate Net-Zero Standard V2 take effect?

The Corporate Net-Zero Standard V2.0 becomes mandatory for all new target submissions from 1 January 2028. Companies can continue to submit under V1.3 until 31 December 2027. Existing validated targets remain valid for the duration of their target timeframe.

What is the difference between a near-term SBTi target and a net-zero target?

A near-term target sets a 5-10 year emissions-reduction pathway aligned with 1.5°C. A net-zero target sits on top of the near-term target, commits to a long-term deep-reduction pathway (typically 90%+ by 2050), and requires neutralisation of all residual emissions at the target year. Net-zero targets now require at least 41% of neutralisation through long-lived removals.

Does SBTi allow carbon offsets?

No. SBTi does not recognise carbon offsets or avoided emissions toward near-term or long-term reduction targets. Removals only count at the net-zero target year for neutralising residual emissions, and must meet a strict quality threshold. Offsets can still be used outside the SBTi framework under the new Ongoing Emissions Responsibility tier.

How does SBTi validation interact with CSRD and ISSB disclosure?

A validated SBTi target largely satisfies the target-disclosure requirements of ESRS E1 under CSRD and IFRS S2 under ISSB. Regulators treat SBTi validation as third-party evidence that a target is Paris-aligned, which reduces the assurance burden during mandatory reporting cycles.

Who qualifies as a Category A company under V2?

Category A covers large companies globally, plus medium-sized companies headquartered in high-income countries — typically those with more than $450 million in turnover or assets and more than 1,000 employees. Category A companies face the strictest V2 obligations, including a transition plan within 12 months of initial validation and limited assurance on emissions data.

How long does SBTi validation take?

Under V1.3, validation of a submitted target typically takes 30 days, though the full preparation cycle — inventory, pathway design, internal review, submission — typically runs 6-18 months. Under V2, the cyclical model adds renewal validations every few years to confirm progress and recalibrate pathways.
