The numbers tell a story of extreme corporate hesitation.
Between late 2023 and mid-2025, the number of companies setting validated science-based climate targets surged to over 10,000, representing over 40% of global market capitalization.
Yet, at the exact same time, credit retirements in the voluntary carbon market dropped by 7%.
The corporate world has signed up for net-zero in record numbers, but they have quietly stepped away from actually buying the environmental assets required to fund that transition.
To close this gap, the Science Based Targets initiative (SBTi) has introduced its Corporate Net-Zero Standard Version 2.0 . This structural rewrite of corporate climate rules does not just adjust target metrics; it integrates carbon finance directly into short-term financial reporting and transition plans.
The OER Framework: Shifting Carbon Credits from 2050 to Today
Historically, corporate climate standards treated carbon credits as a 2050 problem—a distant "neutralization" tool to be deployed only after decades of direct emissions reductions.
The V2.0 draft completely reframes this timeline through the Ongoing Emissions Responsibility (OER) framework.
Instead of waiting for 2050, companies are now incentivized to take accountability for their unabated emissions annually during their transition journey.
To qualify for the SBTi’s new "Recognized" or "Leadership" climate status, companies can no longer stand still. They must choose between two distinct operational pathways:
The Recognized Pathway: A company must cover at least 1% of its total Scope 1-3 ongoing emissions using high-integrity, ex-post carbon credits, or apply a minimum internal carbon price of $20 per tonne to those emissions to fund external mitigation.
The Leadership Pathway: This requires a company to apply an internal carbon price of at least $80 per tonne to its emissions and direct the resulting capital to fund certified mitigation activities equivalent to at least 40% of their unabated footprint.
By embedding high-integrity credits into these intermediate tiers, SBTi is effectively transforming optional carbon finance into a structured compliance-adjacent benchmark.
Raising the Bar: Stricter Rules for Scope 1, 2, and 3 Accounting
V2.0 is not just about adding offset options; it is aggressively tightening the accounting boundaries on direct and indirect operations.
First, Scope 1 and Scope 2 targets are no longer bundled together. Under the default linear contraction method, Scope 1 emissions must follow a straight-line reduction pathway to zero, supported by capital-planning asset replacement timelines.
Second, energy procurement standards are getting significantly tougher. Large electricity consumers emitting or purchasing energy above 10 GWh must begin hourly electricity matching by 2030, moving away from annual averages. Furthermore, Energy Attribute Certificates (EACs) must originate from low-carbon facilities commissioned within the past 10 years.
Third, Scope 3 targets are shifting to focus strictly on significant categories representing over 5% of a company’s total value-chain footprint, utilizing intensity benchmarks and circularity targets rather than broad, unmanageable supplier engagement surveys.
The 2035 Removals Mandate: A Looming Market Squeeze
The long-term play in V2.0 is a hard transition to carbon dioxide removals (CDR).
From 2035 onward, SBTi will make it mandatory for large companies to utilize permanent carbon removals to neutralize a rising share of their ongoing unabated emissions.
This rule turns what is today a voluntary technology-investment choice into a structural, forward-looking operational requirement.
Because high-durability, permanent carbon removal capacity is currently extremely limited, companies that delay securing their pipelines face significant future supply risks and top-of-market pricing.
This explains why the forward-offtake-to-spot ratio for high-durability CDR currently stands at an astounding 1:70. Sophisticated buyers are already signing multi-year offtake agreements today to lock in future delivery before the 2035 mandate triggers a massive market squeeze.
Transitioning Your Carbon Strategy
Stop viewing SBTi targets as a remote sustainability exercise.
The shift from Version 1 to Version 2 is a shift from marketing ambition to balance-sheet accountability.
To protect your business from future compliance and supply-chain shocks, your team must:
Align your internal carbon pricing with OER: If you are not already pricing carbon internally at a minimum of $20 per tonne, implement it now to build the capital pools needed for transition investment.
Execute forward contracts for removals early: Do not wait until 2035 to evaluate the engineered removals market. Secure early-stage forward offtake agreements to lock in supply and hedge against future price spikes.
Integrate emissions targets into capital planning: Use SBTi's asset-decarbonization pathways to align your equipment-replacement cycles directly with your emission-reduction milestones, ensuring capital expenditures actively support your transition plan.
The companies that protect their operating margins in this high-tax environment will not be those that search for the cheapest offsets. They will be the ones that treat carbon liabilities with the same financial discipline as interest rate or currency risks, securing their compliance-eligible supply long before the tax bill arrives.
