SBTi Corporate Net-Zero Standard V2.0: How GNFZ certification closes the asset-level gap
The Science Based Targets initiative (SBTi) published the final Corporate Net-Zero Standard Version 2.0 on June 11, 2026, marking the framework’s most significant revision since its 2021 launch. That same month, ISO opened public consultation on ISO/DIS 14060, the first international standard for organizational net zero alignment.
Together, these developments raise a consequential question for the buildings sector which accounts for more than one-third of energy-related emissions and is projected to add roughly 15% more floor area by 2030: What constitutes credible proof that a building, or a building portfolio, is decarbonizing on schedule?
Notable Features of SBTi V2.0
SBTi describes V2.0 as a shift from ambition to implementation, with approximately 40% of the standard introducing new requirements or guidance.
The principal changes include:
Two company categories: Category A, comprising large companies subject to mandatory transition plans and third-party assurance, and Category B, comprising SMEs and companies in lower-income-countries with lighter requirements.
Separate Scope 1 and Scope 2 targets, replacing the combined Scopes 1+2 option.
A fixed five-year cycle for near-term targets tied to each company’s transition-plan period.
An implementation hierarchy that prioritizes direct emissions reductions before the use of market instruments.
A wider, more pragmatic use of instruments such as low-carbon electricity certificates and sector specific approaches, while continuing to prohibit carbon credits from counting toward reduction targets;
A best-efforts compliance model that allows Category A companies to retain validation when they can demonstrate and disclose genuine implementation effort rather than losing it outright for missing a target.
Formalized, tiered guidance on carbon removals.
Beginning in 2035, a defined ongoing responsibility for emissions that remain beyond a company's long-term target date.
The Major Distinction from V1.0/V1.3.1
Version 2.0 marks a shift from one uniform pathway to a differentiated two-category framework. It also expands the focus of what SBTi validation beyond the target itself to include the transition plan and evidence of implementation behind it.
V1.3.1 is fundamentally a target-setting and validation standard.
V2.0 is a target-setting, implementation and accountability standard.
Companies will not be required to switch to V2.0 immediately. Beginning in the first quarter of 2027, V2.0 is optional alongside V1.3.1. V2.0 becomes mandatory for new submissions on February 1, 2028.
V1.3.1's recent recommendations, including the use of a 2030 near-term target year and consistent base years, already exist to help companies land inside V2.0's future transition-plan cycle without having to restart the target-setting process.
The SBTi Net Zero Standards, in Brief
The Corporate Net-Zero Standard establishes the cross-cutting requirements for target boundaries, Scope 1, 2, and 3 emissions coverage, ambition levels, the neutralization of residual emissions, and five-year review cycles.
For activities and emissions sources covered by the buildings criteria, those sector-specific requirements take precedence over the corresponding Corporate Net-Zero Standard. The Buildings Sector Criteria are mandatory for any company that owns, develops, manages or finances real estate when either in-use operational emissions reach 20% of total Scope 1–3 emissions, or upfront embodied emissions from new construction meet the same threshold.
The criteria recognize four distinct user types — developers, owner-occupiers, owner-lessors, and property managers — each with specific obligations, built around a clean split between in-use operational emissions (measured via the Sectoral Decarbonization Approach, in kgCO₂e/m²) and upfront embodied emissions of new construction. Covered companies must make a public commitment to install no new fossil-fuel equipment beginning in 2030.
What This Means for Buildings, and How ISO 14060 Fits In
ISO and SBTi have worked to align ISO/DIS 14060 with the Corporate Net-Zero Standard V2.0, reflecting growing convergence around the requirements for credible organizational net zero claims. However, it is important to note that both frameworks operate primarily at the organizational level; neither provides standalone verification of an individual building’s decarbonization performance.
Feedback from commercial real estate stakeholders has already identified the consequence of not providing standalone verification. SBTi's best-efforts model and wider acceptance of certificates may make an organization-level validation a less reliable indicator for which specific assets are reducing emissions. This leaves owners, lenders and fund managers with less certainty about where to make decarbonization investments at the level of the individual building.
Where GNFZ Net Zero Certification Fits
GNFZ's Net Zero Certifications were designed to fill this exact building asset gap. GNFZ certifies performance towards Net Zero Energy, Emissions, Water and/or Waste, tracking all the way from an initial emissions assessment through a staged decarbonization plan, incremental progress and final methodology, verifying metered, site-level data before any group-level claim or market instrument is layered on.
Because our certification platform is based on the GHG Protocol and ISO 14064 principles and mirrors the same in-use-operational-versus-upfront-embodied split as the SBTi Buildings Criteria, a well-governed emissions dataset can support both an SBTi submission and GNFZ certification, without duplicating data collection.
Mindspace Business Parks REIT demonstrates how this approach can be applied at scale. Its portfolio of 56 commercial assets across Mumbai, Pune, Hyderabad, and Chennai (representing approximately 2.07 million square meters of gross floor area) is registered for GNFZ’s portfolio-level Net Zero Emissions Certification.
Mindspace developed its greenhouse gas inventory in accordance with the GHG Protocol and ISO 14064-1 and had it independently verified as part of its FY 2024–25 ESG Report. That inventory supports both its SBTi target submission, including a target to reduce Scope 3, Category 2 emissions by 63.3% by 2034, and GNFZ’s ongoing assessment of the portfolio.
GNFZ evaluates the same underlying data against relevant boundary and accounting requirements, identifies gaps, and recommends corrective actions to incrementally and credibly advance the portfolio toward net zero. For Mindspace, the advantage is clear: one rigorous, independently verified inventory can support two complementary outcomes, corporate target validation and asset-level certification, without duplicating the underlying data effort.
Conclusion
The bottom line and why it matters: SBTi Version 2.0 makes corporate net zero commitments more differentiated, implementation-focused, and flexible in how companies demonstrate progress. ISO 14060 is advancing a complementary organizational framework for credible and verifiable net zero alignment.
Neither, however, provides standalone verification that an individual building, or every asset within a portfolio, is decarbonizing as required. GNFZ’s net zero certifications are designed to close that gap by verifying asset-level performance across energy, emissions, water, and waste, using the same GHG Protocol and ISO 14064 foundations that support corporate target-setting and reporting.
The practical benefit is not another layer of duplicative work, but greater value from the work already done. Mindspace REIT’s independently verified GHG inventory now supports both its SBTi submission and its GNFZ portfolio certification assessment, thereby demonstrating how a single, well-governed dataset can connect corporate ambition with measurable performance across individual assets.
If your organization wants to determine whether its existing GHG inventory is ready to support asset-level verification, speak with the GNFZ team about a Net Zero Certification assessment for your portfolio.
