SBTi Corporate Net-Zero Target Calculator | Long-Term Abatement, Residual Emissions & Required Removals
Enter your base-year Scope 1, 2 and 3 inventory and a net-zero target year, and the calculator resolves the long-term abatement required under the SBTi Corporate Net-Zero Standard — the target emissions, the residual you may carry, and the permanent removals you must neutralise it with — on either the cross-sector Absolute Contraction pathway or a sector pathway.
A net-zero target is two commitments, not one. The SBTi Corporate Net-Zero Standard requires a company to cut emissions deeply across its whole value chain — a long-term target of at least a 90% reduction by 2050 at the latest — and then to neutralise the small residual that remains with permanent carbon removals. This calculator resolves that long-term leg: given a base-year inventory and a net-zero year, it returns the target emissions, the residual you may retain, and the removals needed to reach a state of net zero. It does not set your near-term target — that is a separate, prerequisite step.
What it computes. You enter the base year, a net-zero target year no later than 2050, the Scope 1, 2 and 3 baseline in tonnes of CO₂ equivalent, your long-term Scope 3 coverage, and a pathway: the cross-sector Absolute Contraction Approach or a sector pathway. The tool returns the long-term abatement percentage, the long-term target emissions, the residual emissions (held to no more than 10% of base), the permanent removals required to neutralise that residual, the total reduction in tonnes, and the split across Scope 1 and 2 versus Scope 3. In cross-sector mode it also marks the 2030 checkpoint on the long-term trajectory.
Why long-term and net-zero, not near-term. The SBTi framework has two target horizons. The near-term target — roughly a halving of emissions across five to ten years, driven by a linear annual reduction rate — is the entry requirement and is scoped by the companion SBTi near-term target calculator. This calculator handles the long-term and net-zero horizon: the deep end-state reduction and the neutralisation of what is left. The two are sequential, not interchangeable; a valid net-zero commitment rests on a validated near-term target underneath it.
The inventory basis. The tool consumes a Scope 1, 2 and 3 inventory you have already compiled on a GHG Protocol Corporate Standard basis, expressed as pre-aggregated tonnes of CO₂ equivalent using the IPCC AR6 100-year global-warming-potential values. It does not weight individual gases itself; it works from the totals. Build those totals with the scope calculators first — the net-zero tool scopes the target, not the inventory.
Source basis. The target-year ceiling, the Scope 3 coverage and materiality thresholds, the FLAG separate-target trigger, the allowable exclusion limit, the recalculation cadence and the renewable-electricity milestone are read live from the GreenCalculus Master Brain (section sbti_pathways, source SBTI_CORPORATE_2026). The 90% long-term reduction floor and the ten-year “halving” reading of the near-term rate are stated from the SBTi Corporate Net-Zero Standard V1.3.1 itself, not held as Master Brain numbers. Because the framework is revised periodically, confirm any target against the current SBTi criteria before submitting it for validation.

Computes the long-term abatement endpoint, the residual, and the permanent removals needed to neutralize it — with a 4-pillar SBTi validation pre-check.
Results are indicative, intended for target scoping and screening. A validated SBTi Corporate Net-Zero target requires the full four-pillar submission (near-term SBT, long-term SBT, neutralization, and recommended BVCM) through the SBTi validation process. In sector-pathway (SDA) mode, the company-specific target and year-by-year convergence are computed by the SBTi sector target-setting tool — this calculator surfaces published endpoints and does not interpolate the sector pathway. Confirm all figures against the current SBTi Corporate Net-Zero Standard and your audited GHG inventory.
Most companies treat “net zero” as a single number to announce. The SBTi treats it as two obligations in sequence: cut almost everything, then neutralise the little that is genuinely left — and it will not let the second stand in for the first.
The hard question is not “what do we offset?” but “what is the deepest reduction we can commit to, and how small can we make the residual we then have to remove from the atmosphere permanently?”
An SBTi net-zero target requires cutting value-chain emissions by at least 90% from the base year by 2050, then neutralising the residual — no more than 10% — with permanent removals. Credits cannot substitute for the reduction.
This calculator implements the SBTi Corporate Net-Zero Standard V1.3.1, read alongside the Near-Term Criteria V5.3.1. A net-zero target under the Standard means two things: a long-term reduction of at least 90% of value-chain emissions from the base year, reached by 2050 at the latest, and the neutralisation of the remaining residual — no more than 10% of the baseline — with permanent carbon removals. Carbon credits do not substitute for the reduction. A validated near-term target is a prerequisite. The Standard is revised periodically, so confirm any target against the current SBTi criteria before submitting it for validation.
What this calculator determines
The calculator resolves the long-term and net-zero leg of an SBTi target. From a base-year Scope 1, 2 and 3 inventory and a net-zero target year, it returns the long-term abatement percentage, the long-term target emissions, the residual you may carry, the permanent removals needed to neutralise that residual, and the split between Scope 1 and 2 and Scope 3. It scopes the end state — “how deep, by when, and how much is left to remove” — not the inventory itself, and not the near-term target that sits beneath it.
Long-term and net-zero, not near-term
The SBTi framework runs on two horizons, and this tool occupies the second. The near-term target — the entry requirement, roughly a halving of emissions over five to ten years — is scoped by the companion SBTi near-term target calculator. This calculator takes the long-term view: the deep end-state reduction of at least 90% and the neutralisation of the residual. It takes two years — a base year and a net-zero year no later than 2050 — and treats the 2030 point as a checkpoint along the long-term path, not as a separately computed near-term target.
It scopes the target, not the inventory
The tool consumes a Scope 1, 2 and 3 inventory you have already compiled, in pre-aggregated tonnes of CO₂ equivalent, and works from those totals. It does not measure emissions, weight individual greenhouse gases, or build the inventory — those are upstream steps. What it adds is the target mathematics: applying the long-term abatement to the baseline, holding the residual within the permitted ceiling, and sizing the removals that close the gap to net zero.
This calculator handles the long-term and net-zero horizon: a reduction of at least 90% of base-year value-chain emissions by 2050 at the latest, plus the permanent removals needed to neutralise the residual. It does not compute a near-term target — that prerequisite is scoped separately. Inputs are a base year, a net-zero year, and a pre-aggregated Scope 1, 2 and 3 baseline; outputs are the abatement, the target emissions, the residual and the removals.
The net-zero architecture — reduce, then neutralise
A net-zero target under the SBTi Corporate Net-Zero Standard V1.3.1 is built on a clear hierarchy: reduce first, as deeply as the science requires, and only then neutralise what genuinely cannot be eliminated. The four pillars below describe that architecture. They are interpretive provisions of the Standard, cited to it rather than to any single calculated value.
Near-term target
A validated near-term target — roughly halving value-chain emissions within five to ten years — is the foundation. It is the prerequisite, not part of this calculator’s output, and is scoped with the near-term tool.
Long-term target
A reduction of at least 90% of base-year emissions across Scopes 1, 2 and 3, reached by 2050 at the latest. This is the deep end-state abatement the calculator resolves for your baseline.
Neutralise residuals
The remaining residual — no more than about 10% of the baseline — is neutralised with permanent carbon removals at the net-zero point. The calculator sizes the removals as equal to the residual.
Beyond value chain
Companies are recommended to invest in additional mitigation outside their value chain — beyond-value-chain mitigation — on the way to net zero. It is a recommendation, not a substitute for the reduction or the neutralisation.
The 90% reduction and the 10% residual
The defining number of a long-term SBTi target is the depth of reduction: at least 90% of base-year value-chain emissions, leaving a residual of no more than around 10%. The GreenCalculus engine applies a 90% long-term abatement by default and treats it as a validation floor, which is why the calculator sizes the residual at no more than a tenth of the baseline. That residual is what removals neutralise — and the smaller a company can make it through genuine reduction, the less it must remove. The 90% floor is stated from the Standard rather than read as a single Master Brain figure; the Master Brain expresses the requirement qualitatively, as a residual level consistent with 1.5°C.
Neutralisation sits at the end, not throughout
Neutralisation applies to the residual at the net-zero point, not as a running offset against emissions along the way. A company reaches net zero when it has cut emissions by at least 90% and neutralised the remaining residual with permanent removals — not when it has bought enough credits to match its current footprint. This sequence is the whole point of the architecture: the reduction does the work, and neutralisation closes only the unavoidable remainder.
A net-zero target is not an offsetting target.
Under the Standard, at least 90% of the work is reduction; removals neutralise only the residual that deep decarbonisation cannot reach.
Where the near-term target fits
Although this calculator resolves the long-term and net-zero leg, that leg does not stand alone. A net-zero commitment is only valid on top of a validated near-term target, so it is worth being precise about how the two relate — and why the 2030 figure this tool shows is a checkpoint, not a near-term target.
The near-term target is the prerequisite
The near-term target commits a company to roughly halving its value-chain emissions over five to ten years. On the cross-sector pathway it is driven by a linear absolute reduction of about 4.2% per year — a rate derived from the IPCC SR1.5 carbon budget and held in the Master Brain — applied from the base year. That near-term mathematics belongs to the SBTi near-term target calculator; this net-zero tool reads the rate into its parameter set for reference but does not apply it. Scope the near-term target there first, then return here for the long-term and net-zero leg.
The 2030 point is a checkpoint, not a target
In cross-sector mode this calculator plots a straight-line trajectory from the base-year baseline down to the net-zero target emissions, and marks the year 2030 on that line. That 2030 figure is simply where the long-term path passes through 2030 — a checkpoint for orientation. It is not the independently validated near-term target, which is computed on the near-term rate over the near-term horizon and will usually differ. Read the checkpoint as a progress marker on the long-term curve, and the near-term tool’s output as the actual near-term commitment.
Set the near-term target first. A net-zero target submitted without a validated near-term target underneath it is incomplete under the Standard. The roughly 4.2%-per-year cross-sector rate that defines the near-term leg is the near-term calculator’s mathematics — this tool references it but does not apply it, so use the two calculators in sequence: near-term for the next decade, this one for the end state.
Choosing a pathway — cross-sector ACA vs sector
The Standard offers two ways to set the depth of reduction: a single cross-sector rate that applies to most companies, and sector-specific pathways for emissions-intensive industries where a uniform percentage would not reflect the technology. The calculator supports both, and they produce different output shapes.
| Pathway | Who uses it | Mechanics | Calculator output |
|---|---|---|---|
| Cross-sector — Absolute Contraction Approach (ACA) | Most companies, across all sectors without a specific pathway | A linear absolute reduction applied to total emissions; near-term leg ≈ 4.2%/yr, long-term to ≥90% | Year-by-year trajectory, base year to net zero, with the 2030 checkpoint and cumulative budget |
| Sector pathway — Sectoral Decarbonization Approach (SDA) | Emissions-intensive sectors with a defined SBTi pathway | Convergence to a sector emissions-intensity benchmark, by physical activity | Sector endpoint table — intensities and implied absolutes; no year-by-year series |
SBTi pathway options as implemented by the calculator. The cross-sector ACA produces a deterministic linear trajectory; the SDA produces sector endpoints rather than a time series. The ≈4.2%/yr figure is the cross-sector near-term rate (held in the Master Brain, derived from IPCC SR1.5) and is applied by the near-term calculator, not this one. Source: SBTi Corporate Net-Zero Standard V1.3.1; Near-Term Criteria V5.3.1.
Cross-sector Absolute Contraction
The Absolute Contraction Approach reduces a company’s total emissions by a fixed percentage each year, regardless of growth in output — an absolute cut, not an intensity improvement. It is the default for companies without a sector pathway, and it is what this calculator uses to plot the long-term trajectory from the baseline down to the net-zero target emissions. The near-term portion of that contraction runs at roughly 4.2% per year; the long-term portion deepens to at least a 90% total reduction by the net-zero year.
Sector pathways and their coverage
For emissions-intensive industries, the Sectoral Decarbonization Approach sets a pathway to a sector-specific emissions-intensity benchmark, converged by physical activity rather than a flat percentage. The calculator carries sector pathways for eleven sectors, but the available detail varies by sector: only steel, cement and aluminium (with both 2030 and 2050 intensity endpoints) and power (with a 2050 endpoint) let the engine compute an implied absolute endpoint from activity data. For the others — maritime, buildings, apparel and footwear, chemicals, aviation, road transport and FLAG — the tool surfaces the qualitative pathway and defers the detailed company-specific target to the SBTi sector target-setting tool.
Sector pathway coverage is not uniform. The calculator can compute an implied absolute endpoint only for steel, cement and aluminium (2030 and 2050) and power (2050); for the other sectors it surfaces qualitative pathway information and defers the interior, company-specific target to the dedicated SBTi sector tool. Do not read a missing intensity endpoint as “no requirement” — it means the detailed target is set with the sector tool, not this one.
If your company is in agriculture, forestry or other land use, your FLAG emissions are handled under SBTi FLAG guidance, with a separate FLAG target required once FLAG emissions reach about 20% of the total, and a no-deforestation commitment dated within two years of FLAG target submission and by 31 December 2030 at the latest. Scope the energy-and-industry side here and the land side under FLAG; the two combine into the overall net-zero target.
Scope 3 — the 67%, 90% and 40% thresholds
Scope 3 — value-chain emissions — is usually the largest part of a company’s footprint and the hardest to cut, so the Standard sets explicit coverage rules for it. Three thresholds govern when and how much Scope 3 must be included, and the calculator reads two of them live.
| Threshold | Value | What it governs | In this calculator |
|---|---|---|---|
| Scope 3 materiality | 40% | If Scope 3 is at least this share of total emissions, a Scope 3 target is required | Read live — triggers the Scope 3 requirement |
| Near-term Scope 3 coverage | 67% | Minimum share of Scope 3 a near-term target must cover | The near-term boundary — set in the near-term tool |
| Long-term Scope 3 coverage | 90% | Minimum share of Scope 3 a long-term target must cover | Read live — enforced on the long-term target |
SBTi Scope 3 thresholds. The 40% materiality trigger and the 90% long-term coverage requirement are read live by this calculator from the Master Brain. The 67% near-term coverage threshold is the near-term target’s boundary — its Master Brain row exists but is applied by the near-term calculator, not this one. Source: SBTi Corporate Net-Zero Standard V1.3.1, criteria C4 and C7; Near-Term Criteria V5.3.1.
When a Scope 3 target is required
If Scope 3 is at least 40% of total emissions — which it is for most companies — a Scope 3 target is mandatory, not optional. The calculator reads this materiality threshold live and triggers the Scope 3 requirement accordingly. Given how dominant value-chain emissions are in most footprints, the practical effect is that nearly every company setting an SBTi target must address Scope 3 head-on rather than reporting Scopes 1 and 2 alone. The Scope 3 Category 1 spend-based calculator is a starting point for the value-chain data the target rests on.
Near-term 67%, long-term 90%
The coverage requirement tightens between the two horizons. A near-term target must cover at least 67% of Scope 3 emissions; a long-term target must cover at least 90%. This calculator enforces the 90% long-term figure — it is read live and applied to the long-term target — while the 67% near-term figure belongs to the near-term tool. The widening coverage reflects the Standard’s logic: the value chain that is partly addressed in the near term must be almost fully addressed by the time a company reaches net zero.
Long-term Scope 3 coverage must reach at least 90%. A net-zero target that leaves a large slice of value-chain emissions outside the target boundary will not meet the long-term coverage requirement, however deep the reduction on the covered portion. Check that the Scope 3 coverage you enter reflects at least 90% of your value-chain emissions before relying on the long-term result.
Removals, neutralisation and why offsets don’t count
The most misread part of the net-zero architecture is the role of carbon credits. The Standard draws a hard line: emission reductions and permanent removals do the work, and avoidance-based offsets cannot substitute for either. Understanding this distinction is the difference between a credible net-zero target and a re-labelled offsetting programme.
Reductions and removals are not the same as offsets
A long-term SBTi target is met by reducing a company’s own value-chain emissions by at least 90% — actual cuts, not purchased credits. The residual that remains is neutralised by permanent carbon removals: drawing CO₂ out of the atmosphere and storing it durably, in an amount equal to the residual. Avoidance-based carbon credits — paying for emissions not to happen elsewhere — do not count toward either the reduction or the neutralisation under the Standard. This calculator sizes required removals as equal to the residual emissions, reflecting that neutralisation is a one-for-one removal of what is genuinely left, not an offset of the whole footprint.
Beyond-value-chain mitigation is additional, not a substitute
The Standard recommends that companies also finance climate mitigation outside their own value chain — beyond-value-chain mitigation — as a contribution to the global transition while they decarbonise. This is encouraged and additional; it is explicitly not a way to discharge the reduction or the neutralisation obligation. A company cannot buy its way to a lower long-term target, and the calculator does not net any such purchase against the required abatement.
Under the SBTi Corporate Net-Zero Standard, at least 90% of the target is met by reducing the company’s own emissions. The residual is neutralised one-for-one with permanent carbon removals — not avoidance offsets. Beyond-value-chain mitigation is recommended but additional, never a substitute for the reduction or the neutralisation. The calculator sizes removals as equal to the residual and nets no credits against the required reduction.
How the calculator works
You enter the base year, the net-zero year, the Scope 1, 2 and 3 baseline, the long-term Scope 3 coverage, and a pathway; the calculator resolves the long-term abatement and the removals needed to close the residual.
Enter baseline and years
The base year, a net-zero target year no later than 2050, and the Scope 1, 2 and 3 baseline in tonnes of CO₂ equivalent — pre-aggregated on a GHG Protocol basis using AR6 GWP-100 values. Add the long-term Scope 3 coverage and, for sector mode, the sector and physical activity.
Choose the pathway
Cross-sector Absolute Contraction for most companies, or a sector pathway where one applies. Cross-sector mode plots a linear trajectory to the net-zero year; sector mode resolves the relevant intensity endpoints.
Read the result
The long-term abatement percentage, the long-term target emissions, the residual (no more than 10% of base), the permanent removals required to neutralise it, the total reduction, and the Scope 1 and 2 versus Scope 3 split — plus a net-zero validation pre-check and an audit trail.
The net-zero year cannot be later than 2050, and the long-term abatement defaults to 90% — the Standard’s floor. If you lower the coverage or abatement below the Standard’s thresholds, the validation pre-check will flag it: the tool will still compute a result, but it will not be a target the SBTi would validate. Use the pre-check as a first screen, and confirm against the current SBTi criteria before submission.
Worked example — a 500,000 tCO₂e baseline
This example is illustrative and shows the long-term and net-zero mathematics, not an emissions measurement — the tool scopes the target from a baseline you supply. Consider a company on the cross-sector Absolute Contraction pathway with a 2022 base year, a 2050 net-zero year, and a base-year inventory of 40,000 tCO₂e Scope 1, 60,000 Scope 2 and 400,000 Scope 3 — a total baseline of 500,000 tCO₂e — setting a long-term target at the 90% default with 90% Scope 3 coverage.
Resolving the long-term target
At a 90% long-term abatement, the long-term target emissions are 10% of the baseline: 50,000 tCO₂e. That 50,000 tCO₂e is the residual the company may carry at net zero — within the Standard’s ten-percent ceiling — and the permanent removals required to neutralise it are equal to it, also 50,000 tCO₂e. The total reduction the target commits to is the other 90%: 450,000 tCO₂e cut from the baseline through genuine decarbonisation across Scopes 1, 2 and 3.
The trajectory and its 2030 checkpoint
On the cross-sector pathway the calculator draws a straight line from 500,000 tCO₂e in 2022 to 50,000 tCO₂e in 2050 — a reduction of 450,000 tCO₂e over 28 years, or about 16,071 tCO₂e a year. Where that line crosses 2030, eight years in, emissions are about 371,429 tCO₂e, roughly 25.7% below the baseline. The table below is deterministic for these inputs.
| Point on the long-term path | Year | Emissions (tCO₂e) | Reduction vs base |
|---|---|---|---|
| Base year | 2022 | 500,000 | — |
| 2030 checkpoint (not a near-term target) | 2030 | ~371,429 | ~25.7% |
| Net-zero target — long-term emissions | 2050 | 50,000 | 90% |
| Residual neutralised by permanent removals | 2050 | 50,000 | ≤10% (residual) |
Illustrative long-term trajectory for the stated example inputs (500,000 tCO₂e baseline, 2022 base year, 2050 net-zero year, cross-sector ACA, 90% long-term abatement). The figures are deterministic for these inputs; the live tool will render the same numbers for the same inputs, and different numbers for different ones. The 2030 figure is a checkpoint on the long-term line, not the validated near-term target, which is computed separately on the near-term rate. Source: SBTi Corporate Net-Zero Standard V1.3.1.
What the near-term leg adds
This example resolves the long-term and net-zero end state. The company’s actual near-term target — the validated commitment for the next decade, roughly a halving on the near-term rate — is computed separately in the SBTi near-term target calculator and will not generally equal the 2030 checkpoint above. The two targets stack: the near-term target governs the next ten years, this long-term target governs the path to 2050, and the removals close the residual at the end.
For a 500,000 tCO₂e baseline at the 90% long-term abatement, the net-zero target emissions are 50,000 tCO₂e, the residual the company may carry is 50,000 tCO₂e — within the 10% ceiling — and the permanent removals required to neutralise it are 50,000 tCO₂e, with a total reduction of 450,000 tCO₂e. The 2030 checkpoint of about 371,429 tCO₂e is a marker on the long-term path, not the validated near-term target.
Net zero vs carbon neutral — SBTi, ISO 14068 and PAS 2060
“Net zero” and “carbon neutral” are routinely used as synonyms, and they are not. An SBTi net-zero target is a science-based reduction commitment with neutralisation of a small residual; carbon-neutrality claims under ISO 14068 and PAS 2060 are offsetting-based demonstrations that can, in principle, be met largely with credits. Knowing the difference prevents both mis-scoping and greenwashing risk.
| Framework | Core claim | Role of offsets | Reduction requirement |
|---|---|---|---|
| SBTi Corporate Net-Zero | Science-based net zero | Permanent removals neutralise residual only; no avoidance offsets | ≥90% reduction by 2050 — the heart of the target |
| ISO 14068-1 | Carbon neutrality | Offsets and removals permitted to balance the footprint | Reduction expected, but offsetting can carry much of the claim |
| PAS 2060 | Carbon-neutral demonstration | Offsets permitted to reach neutrality each period | Reduction plan required; offsets balance the remainder |
Net zero compared with carbon-neutrality frameworks. SBTi net zero is reduction-led with removals neutralising only the residual; ISO 14068-1 and PAS 2060 are neutrality claims in which offsets can carry a large share. Characterisations stated from each framework’s governing document as of June 2026.
vs ISO 14068-1
ISO 14068-1 defines carbon neutrality, allowing offsets and removals to balance a footprint. It is a state that can be claimed without the deep, science-based reduction the SBTi requires. Scope a neutrality claim with the ISO 14068-1 carbon neutrality calculator.
vs PAS 2060
PAS 2060 demonstrates carbon neutrality period by period, requiring a reduction plan but permitting offsets to reach neutral each year. It is a demonstration standard, not a long-horizon decarbonisation target. Compare it with the PAS 2060 carbon-neutral demonstration calculator.
vs the near-term target
Within the SBTi framework itself, the near-term target is the entry step and this long-term target is the destination. Neither is a neutrality claim. Scope the near-term leg with the SBTi near-term target calculator and read the full method on the SBTi net-zero target methodology page.
Common target-setting errors
The recurring mistakes here lead a company to overstate a target, lean on offsets, or confuse the two SBTi horizons. The ones below most often produce a target the SBTi would not validate.
01 — Treating offsets as reductions
Carbon credits do not count toward the 90% reduction. Only genuine cuts to the company’s own value-chain emissions do; permanent removals neutralise the residual only.
02 — Skipping the near-term target
A net-zero target is invalid without a validated near-term target beneath it. Set the near-term leg first, in the near-term calculator, then the long-term and net-zero leg here.
03 — Reading the 2030 checkpoint as the near-term target
The 2030 point on the long-term trajectory is a progress marker, not the validated near-term target, which is computed on the near-term rate over the near-term horizon and usually differs.
04 — Under-covering Scope 3
The long-term target must cover at least 90% of Scope 3. A target that excludes a large slice of value-chain emissions fails the coverage requirement regardless of how deep the covered cut is.
05 — Setting a net-zero year past 2050
The net-zero year cannot be later than 2050. A later date is outside the Standard; the calculator caps the target year at 2050.
06 — Forgetting FLAG and recalculation
Land-intensive companies need a separate FLAG target once FLAG emissions reach about 20% of the total, and every SBTi target must be reviewed on a roughly five-year cadence as the business and the science change.
Scope boundary — what this tool does not cover
This calculator resolves the long-term and net-zero leg of an SBTi target and sizes the removals that neutralise the residual. It does not build the emissions inventory, compute the near-term target, model an interior sector pathway, or submit anything for validation — those are separate tasks, several with their own calculators.
| Task | What it is | In this tool? |
|---|---|---|
| Long-term & net-zero target | Abatement, residual and required removals to net zero | Yes — this is what the calculator scopes |
| Near-term target | The roughly-halving entry target on the near-term rate | No — see the SBTi near-term target calculator |
| Scope 1, 2 & 3 inventory | The base-year emissions the target rests on | No — build it on a GHG Protocol basis first; the tool consumes totals |
| Scope 3 value-chain data | The largest and hardest part of the footprint | Partial — see the Scope 3 Category 1 spend-based calculator |
| Interior sector pathway | Company-specific SDA target inside a sector | No — set with the dedicated SBTi sector target-setting tool |
The target this tool produces is the destination, not the whole journey: once a company knows its long-term abatement, residual and removals, the surrounding work is building the GHG Protocol inventory, setting and validating the near-term target, securing genuine value-chain reductions, and sourcing credible permanent removals for the residual. The full methodological treatment is on the paired SBTi net-zero target methodology page.
A scoped long-term target is not a validated SBTi commitment. It tells you the abatement, residual and removals implied by your baseline and pathway — it does not measure your emissions, set your near-term target, design your decarbonisation plan, or pass SBTi validation. A real net-zero commitment requires a genuine GHG Protocol inventory, a validated near-term target beneath it, and a credible removals strategy for the residual.
Data sources and status transparency
Most parameters are read live from the Master Brain
Unlike some regulatory pages whose parameters are stated only from external instruments, the SBTi target parameters here are largely held in the GreenCalculus Master Brain (section sbti_pathways, source SBTI_CORPORATE_2026) and read live by the engine: the 2050 net-zero year ceiling, the 90% long-term Scope 3 coverage requirement, the 40% Scope 3 materiality trigger, the 20% FLAG separate-target threshold, the 2030 no-deforestation limit, the 5% allowable-exclusion limit, the five-year recalculation cadence, and the 100%-by-2030 renewable-electricity milestone. The cross-sector near-term rate of about 4.2% per year is also held in the Master Brain, though it is applied by the near-term calculator rather than this one.
Two figures are stated from the Standard, not the Master Brain
Two numbers on this page are not single Master Brain values. The 90% long-term reduction floor and its ten-percent residual are stated from the SBTi Corporate Net-Zero Standard V1.3.1 — the Master Brain expresses the requirement qualitatively, as a residual level consistent with 1.5°C, and the engine carries 90% as its default and validation floor. The roughly 42% “halving” by 2030 associated with the near-term leg is interpretive, derived from the 4.2%-per-year rate over about a decade, and is cited to the Absolute Contraction and IPCC SR1.5 basis rather than to any row that literally states 42%. The four-pillar, neutralisation and no-offsets wording is likewise stated from the Standard.
The inventory basis
The Scope 1, 2 and 3 baseline the tool consumes is built on a GHG Protocol Corporate Standard basis using the IPCC AR6 100-year global-warming-potential values — the governing basis for corporate GHG reporting. This calculator performs no gas-by-gas weighting itself; it works from pre-aggregated tonnes of CO₂ equivalent. The IPCC AR6 GWP values are the reference for the inventory the target rests on, applied upstream by the scope calculators.
What the calculator deliberately does not do
The tool does not measure emissions, set the near-term target, model an interior sector pathway, source removals, or submit a target for validation. It scopes the long-term and net-zero leg: baseline and pathway in, abatement, residual and removals out, with a validation pre-check. The commitment the Standard ultimately requires is assembled separately, supported by the linked near-term, Scope 3 and inventory tools.
Versioning
The Master Brain parameters carry the section’s dataset stamp; the two Standard-stated figures and the clause wording are stamped to the verification date of 7 June 2026 and to Standard V1.3.1. The SBTi revises its standards periodically — a new version of the Corporate Net-Zero Standard or the Near-Term Criteria could move any of these — so re-confirm against the current SBTi criteria before treating any output as current. The full methodological treatment is on the paired SBTi net-zero target methodology page.
Frequently asked questions
Under the SBTi Corporate Net-Zero Standard, a net-zero target is a commitment to reduce value-chain emissions by at least 90% from a base year, reaching that level by 2050 at the latest, and then to neutralise the remaining residual — no more than about 10% of the baseline — with permanent carbon removals. It is reduction-led: at least 90% of the work is genuine emission cuts, and removals close only the unavoidable remainder. A validated near-term target, roughly halving emissions within five to ten years, is a prerequisite.
The near-term target is the entry step: roughly halving value-chain emissions over five to ten years, driven on the cross-sector pathway by a linear reduction of about 4.2% per year. The net-zero target is the destination: a reduction of at least 90% by 2050 at the latest, plus neutralisation of the residual with permanent removals. They are sequential — a net-zero target is only valid on top of a validated near-term target. This calculator scopes the net-zero leg; the near-term leg is scoped in the SBTi near-term target calculator.
No — not for the reduction. The at-least-90% reduction must come from genuine cuts to your own value-chain emissions; avoidance-based carbon credits do not count toward it. The residual that remains at net zero is neutralised with permanent carbon removals, in an amount equal to the residual, not with avoidance offsets. The Standard also recommends beyond-value-chain mitigation as an additional contribution, but that is never a substitute for the reduction or the neutralisation. A net-zero target is not an offsetting programme.
At least a 90% reduction of base-year value-chain emissions across Scopes 1, 2 and 3, reached by 2050 at the latest, leaving a residual of no more than about 10% of the baseline. The GreenCalculus engine applies a 90% long-term abatement by default and treats it as a validation floor. The deeper the genuine reduction, the smaller the residual a company must neutralise with permanent removals. The 90% floor is stated from the SBTi Corporate Net-Zero Standard V1.3.1.
After cutting emissions by at least 90%, a company still has a small residual it cannot eliminate. Neutralisation means removing an equal quantity of CO₂ from the atmosphere and storing it durably — permanent carbon removals — so that the residual is balanced at the net-zero point. It applies to the residual at the end, not as a running offset along the way, and it must be removals rather than avoidance credits. The calculator sizes required removals as equal to the residual emissions.
A long-term target must cover at least 90% of Scope 3 emissions; a near-term target must cover at least 67%. Separately, if Scope 3 is at least 40% of total emissions — as it is for most companies — a Scope 3 target is required at all. This calculator reads the 40% materiality trigger and the 90% long-term coverage requirement live and enforces them on the long-term target; the 67% near-term coverage figure is applied by the near-term calculator.
The cross-sector Absolute Contraction Approach reduces a company’s total emissions by a fixed percentage each year regardless of growth — an absolute cut — and is the default for most companies. A sector pathway, the Sectoral Decarbonization Approach, converges a company to a sector-specific emissions-intensity benchmark by physical activity, for emissions-intensive industries. This calculator supports both; in cross-sector mode it plots a year-by-year trajectory to net zero, and in sector mode it resolves the relevant intensity endpoints. Detailed interior sector targets are set with the dedicated SBTi sector tool.
No. An SBTi net-zero target is a science-based reduction commitment — at least 90% cuts by 2050, with removals neutralising only the residual. Carbon-neutrality claims under ISO 14068-1 and PAS 2060 balance a footprint and can, in principle, be met largely with offsets, without the deep, long-horizon reduction the SBTi requires. The two are different in kind: net zero is reduction-led decarbonisation; carbon neutral is a balancing claim. Treating them as synonyms is a common source of greenwashing risk.
The net-zero year cannot be later than 2050 — the calculator caps the target year there. Every SBTi target must also be reviewed and, where needed, recalculated on a roughly five-year cadence, so that it stays consistent with the business as it changes and with the evolving science. Land-intensive companies have an additional requirement: a separate FLAG target once FLAG emissions reach about 20% of the total, and a no-deforestation commitment dated within two years of FLAG target submission and by 31 December 2030 at the latest.
Methodology notes and limitations
Long-term and net-zero scoping tool, not a near-term or inventory engine. The calculator resolves the long-term abatement, the residual and the required permanent removals from a base-year Scope 1, 2 and 3 inventory and a net-zero target year. It does not compute the near-term target — that is the companion near-term calculator — and it does not build the emissions inventory or submit a target for validation.
The 2030 figure is a checkpoint. In cross-sector mode the tool plots a linear trajectory from the baseline to the net-zero target emissions and marks 2030 on it. That figure is a progress marker on the long-term path, not the independently validated near-term target, which is computed on the near-term rate over the near-term horizon and will usually differ.
Most parameters are Master Brain-backed. The 2050 ceiling, 90% long-term Scope 3 coverage, 40% Scope 3 materiality, 20% FLAG threshold, 2030 no-deforestation limit, 5% allowable exclusion, five-year recalculation cadence and 100%-by-2030 renewable-electricity milestone are read live from the Master Brain (section sbti_pathways, source SBTI_CORPORATE_2026). The about-4.2%-per-year cross-sector rate is also Master Brain-held but is applied by the near-term calculator, not this one.
Two figures are stated from the Standard. The 90% long-term reduction floor and ten-percent residual are stated from the SBTi Corporate Net-Zero Standard V1.3.1 and carried as the engine’s default and validation floor — the Master Brain expresses the requirement qualitatively, not as a single 90% row. The roughly 42% “halving” by 2030 is interpretive, derived from the cross-sector rate, and cited to the Absolute Contraction and IPCC SR1.5 basis. The four-pillar, neutralisation and no-offsets wording is stated from the Standard.
Sector pathway coverage is partial. The calculator carries sector pathways for eleven sectors, but only steel, cement and aluminium (2030 and 2050 endpoints) and power (2050) let the engine compute an implied absolute endpoint; the others surface qualitative pathway information and defer the company-specific target to the dedicated SBTi sector target-setting tool.
Emissions basis. The tool consumes a pre-aggregated Scope 1, 2 and 3 inventory built on a GHG Protocol Corporate Standard basis using IPCC AR6 GWP-100 values. It performs no gas-by-gas weighting itself; it works from totals in tonnes of CO₂ equivalent.
Worked example is illustrative. The 500,000 tCO₂e example shows the long-term and net-zero mathematics — 90% abatement, 50,000 tCO₂e residual and removals, 450,000 tCO₂e total reduction, with a 2030 checkpoint of about 371,429 tCO₂e — for the stated inputs, not an emissions measurement.
The Standard changes. The SBTi revises its standards periodically; a new version of the Corporate Net-Zero Standard or the Near-Term Criteria could move any of these parameters. Re-confirm against the current SBTi criteria, and re-run the target, before treating any output as current. The full methodological treatment is on the paired SBTi net-zero target methodology page.
