Ongoing Emissions Responsibility

Background: Companies will continue to emit GHGs on the path to net-zero. By covering a defined share of these ongoing emissions through climate contributions that support verified mitigation and other climate actions beyond their validated target requirements, companies can help limit temperature overshoot, mitigate transition risks, and support climate solutions. To encourage this, the voluntary Ongoing Emissions Responsibility (OER) recognition program will recognize companies for their climate contributions on the SBTi Dashboard.

This chapter sets out criteria that reflect the OER framework’s three phases: the optional recognition program effective under the Corporate Net-Zero Standard V2.0; the post-2035 responsibility requirement; and the net-zero residual emissions requirement. The post-2035 requirement takes effect at a future date, while the net-zero requirement applies once scope 1, scope 2, and scope 3 emissions reach residual levels. Both sets of provisions are included to indicate expectations under the Corporate Net-Zero Standard at the relevant stage.

Under the OER optional recognition program, companies can earn recognition across three levels – Engaged, Advanced, and Leadership – which are distinguished by the volume of emissions covered. The Leadership level represents the full internalization of the cost of climate change, and all companies are encouraged to strive toward the ambition of this level over time.

The OER recognition program will remain optional until 2035, after which Category A companies will be required to support eligible carbon removals. The recognition model will operate in parallel to these post-2035 requirements. By their net-zero target year and thereafter, all companies with net-zero targets are expected to reduce emissions to zero or residual levels and neutralize 100% of residual emissions using eligible carbon removals, either directly or jointly with value chain partners.

The SBTi does not seek to replace existing carbon crediting and climate contribution frameworks. Instead, this chapter establishes minimum criteria for companies to be recognized under the OER framework, which are aligned with existing high-integrity frameworks. The SBTi will develop criteria and processes to recognize relevant third-party frameworks, standards, and programs where applicable.

6.1 Optional OER recognition program: Participation intent

Intent

To encourage participation in the recognition program by making companies’ intent publicly visible, creating a clear signal that differentiates participating and non-participating companies to drive engagement.

CNZS-C38
Companies shall indicate whether they intend to take part in the optional Ongoing Emissions Responsibility recognition program.
Assessment stage
Target Validation
Company category
All companies

6.2 Optional OER recognition program: Eligibility & program structure

Intent

To ensure that recognition is granted only to companies that are delivering against their validated targets and that take responsibility for ongoing emissions by providing climate contributions that support verified mitigation or other climate action at a level aligned with their selected recognition tier.

CNZS-C39
Optional recognition
Recognition for ongoing emissions responsibility shall be assessed and awarded at the End-of-cycle Assessment based on progress against validated targets and delivery of climate contributions in accordance with a selected recognition level.
Assessment stage
End-of-cycle Assessment
Company category
All companies (optional)
CNZS-C40
Optional recognition
Companies shall select a recognition level and, over the near-term target timeframe, deliver climate contributions at a scale determined by the required coverage of ongoing scope 1, scope 2, and scope 3 emissions and contributions under that level.
Assessment stage
End-of-cycle Assessment
Company category

CNZS-C41
Optional recognition
Companies shall use climate contributions to support only eligible verified mitigation outcomes and/or other eligible climate actions toward recognition under the Ongoing Emissions Responsibility recognition program.

All companies (optional)

6.3 Optional OER recognition program: Integrity criteria for supported activities

Intent

To ensure that activities supported under the OER recognition program deliver credible climate impact and adhere to robust integrity and quality standards, safeguarding environmental and social outcomes.

CNZS-C42
Optional recognition
Companies shall ensure that the activities they support as part of the Ongoing Emissions Responsibility recognition program meet recognized third-party high-integrity criteria, where applicable, and SBTi minimum integrity criteria.74
Assessment stage

6.4 Optional OER recognition program: Accounting & reporting

Intent

To ensure that ongoing emissions responsibility is transparently accounted for and reported separately from inventory and target progress, enabling assessment of conformance with standard requirements.

CNZS-C43
Optional recognition
Companies taking part in the Ongoing Emissions Responsibility recognition program shall account for supported verified mitigation outcomes separately from inventory and target progress, and prevent double claiming.
Assessment stage
End-of-cycle Assessment
Company category
All companies (optional)
CNZS-C44
Optional recognition
Companies taking part in the Ongoing Emissions Responsibility recognition program shall report information and obtain independent assurance to demonstrate conformance with their selected recognition level.

6.5 Post-2035: Responsibility Requirement

Intent

To signal future expectations for mandatory ongoing emissions responsibility from 2035 onwards, enabling companies to prepare and build capacity over time.

Disclaimer
This illustrative requirement sets the intention for companies to gradually take responsibility for the impact of their ongoing emissions from 2035 onwards. As this requirement is expected to take effect from 2035, the criteria will be reviewed in the next major revision of the Corporate Net-Zero Standard (Version 3) to reflect the best available science at the time.
CNZS-C45
From 2035, companies shall support eligible carbon removals equal to at least 1% of ongoing scope 1, scope 2, and scope 3 emissions, including a defined and increasing share of long-lived removals.
Assessment stage
End-of-cycle Assessments after 2035
Company category
Category A
Category B (optional)

6.6 Neutralization of residual emissions

Intent

To ensure that a state of net-zero is achieved and maintained through the neutralization of all residual emissions using eligible and integrity-aligned carbon removals.

Disclaimer
The SBTi will continue to review and update the criteria and recommendations in this section in line with scientific advancements.
CNZS-C46
At the net-zero target year and thereafter, companies shall reduce their scope 1, scope 2, and scope 3 emissions to zero or residual levels, and neutralize all residual emissions using eligible carbon removals.
