SBTi V2 Calculator

How it works

What you get

  • Your category. Whether you are Category A or B under Table 2 of the standard, with the reason.
  • Required removals per year. How many tonnes of removals you need each year from 2035 to net zero, split into short-lived and long-lived removals.
  • Cost and offtake. Low, mid and high cost per year, and what it costs to secure part of the removals now with an offtake.

How it works

  1. You enter your company size. We check whether you are Category A or B under Table 2 of the SBTi Corporate Net-Zero Standard V2.0.
  2. You enter your Scope 1, 2 and 3 emissions, your net-zero year and your residual emissions. We assume your emissions fall in a straight line to that residual level.
  3. We apply the removals rules of the standard to each year and split the result into short-lived and long-lived removals.
  4. We price short-lived removals as nature-based removals and long-lived removals as durable removals, each with a low, mid and high price path.

SBTi rules we apply

  • Company category: CNZS V2.0 Table 2. “Depends on balance sheet” is calculated as Category A until you add your balance sheet total.
  • CNZS-C45.1: from 2035, removals equal to at least 1% of your Scope 1, 2 and 3 emissions, rising in a straight line to 100% by your net-zero year. Expected for Category A, optional for Category B. The standard calls this ramp illustrative: SBTi will review it in Version 3, before it takes effect.
  • CNZS-C45.4: at least 10% of these removals are long-lived in 2035, rising in a straight line to 100% by your net-zero year.
  • CNZS-C46: in your net-zero year and after, all residual emissions are neutralised with removals, 100% long-lived under our assumption below. This applies to Category A and B.

Public market prices in 2026, in euros. US dollar prices are converted at the ECB reference rate of 1 October 2026 (1.1298 USD per EUR). The yearly price change per scenario is our modelling assumption, not a published forecast: we found no free public source with numeric long-term price paths.

Before 2035: Ongoing Emissions Responsibility

Ongoing Emissions Responsibility (OER) is an optional recognition program until 2035 (CNZS-C38 to C44). You choose a level and cover part of your ongoing emissions over the five years of your near-term target, either with verified mitigation outcomes (credits) or with a contribution budget. Recognition shows on the SBTi Dashboard.

  • Engaged (CNZS-C40.3): at least 1% of your total Scope 1, 2 and 3 emissions. No set budget; SBTi recommends at least US$20 per tonne (R40.1).
  • Advanced (CNZS-C40.4): all of your Scope 1 and 2 emissions, plus Scope 3 as needed to reach at least 10% of the total. Credits equal in volume, or a budget of US$20 per tonne covered.
  • Leadership (CNZS-C40.5): all of your Scope 1, 2 and 3 emissions, with a budget of US$80 per tonne that also buys credits for every covered tonne. Category B companies may cover the Advanced share instead (CNZS-C40.6).

We use your emissions on the same straight-line pathway, the next five years, avoidance credit prices for the credit route, and the ECB rate for US dollar budgets. Coverage uses location-based Scope 2 (CNZS-C40.1); this calculator uses the Scope 2 figure you enter.

What counts

  • Credits never count toward your emission reduction targets and are not netted from your inventory (CNZS-C43.1). Retire them when you claim them (CNZS-C43.4).
  • Removals from 2035 and at net zero must be delivered in the same reporting period as the emissions they cover (CNZS-C45.2, C46.1). Buying early secures supply and price; it does not bank tonnes for later years.
  • Supported activities must meet the integrity criteria in CNZS-C42, such as additionality, safeguards against reversal and independent assurance. SBTi plans to recognise third-party frameworks; it does not yet name one.
  • Credits used for OER recognition cannot be reused for the 2035 removals or for neutralisation at net zero (CNZS-C43.5).
  • Scope 3 can be covered together with value chain partners that report the same emissions, with a written agreement (CNZS-C40.7).

Assumptions

  • We assume your emissions fall in a straight line to your residual level in your net-zero year, and stay there. Your real pathway will differ.
  • We treat all your emissions as long-lived greenhouse gases (such as CO2 and N2O). This is conservative: it can only overstate the share of long-lived removals. Methane rules are out of scope.
  • Short-lived removals are priced as nature-based removals and long-lived removals as durable removals.
  • If your net-zero year is 2035, the 2035 removals ramp (CNZS-C45) does not apply. Only the neutralisation of residual emissions at net zero (CNZS-C46) is included.
  • An offtake fixes today’s mid price for the share of required removals you secure, over the term you choose.

Questions

What is the difference between Category A and Category B?

Under Table 2 of the standard, a company is Category A if its net turnover is EUR 450 million or more, or it has 1,000 or more employees (FTE), in any country. A company whose ultimate parent is incorporated in a high-income country is also Category A if its Scope 1 and 2 emissions are 10,000 tCO2e or more, or if it meets 2 of these 3: a balance sheet total of EUR 25 million or more, net turnover of EUR 50 million or more, 250 FTE or more. All other companies are Category B. The figures are for the whole group, averaged over the two most recent annual reports.

When does V2.0 apply?

The standard was published in June 2026 and is effective from 1 February 2027. According to the SBTi website, companies can still set targets under Version 1 until 31 January 2028.

Do carbon credits count towards my reduction targets?

No. Under CNZS-C43.1, the mitigation outcomes you support are accounted for separately from your emissions inventory and your target progress, and are not netted from your emissions. Carbon credits must be retired when you claim them (CNZS-C43.4).

What counts as a long-lived removal?

The standard defines a long-lived removal as a carbon dioxide removal activity capable of retaining carbon for centuries to millennia. It does not set a fixed number of years.

What is Ongoing Emissions Responsibility?

Ongoing Emissions Responsibility (OER) is the part of the standard about taking responsibility for the emissions you still release. Until 2035 it is a voluntary recognition program with three levels: Engaged, Advanced and Leadership. The results show what each level would cover and cost for you.
