Join some of the world’s biggest companies by aligning your company’s efforts to cut greenhouse gas emissions with climate science. Follow this four step process and for additional information on each stage please read the Call To Action Guidelines.


Step 1 : Submit the commitment letter

Signing the commitment letter indicates that your company will work to set a science-based emission reduction target. If your company already has an emissions reduction target, the letter confirms your interest in having your existing target independently verified against a set of criteria developed by the Science Based Targets initiative.

After submitting your commitment letter to [email protected] your company will be recognized as “Committed” on our Companies Taking Action page as well as on our partner websites at We Mean Business and CDP. Companies who are engaging in the UN Global Compact will also be recognized on the UN Global Compact website.

Step 2 : Develop a target

Once your company has signed the commitment letter you will have up to 24 months to develop a science-based target.

For support to develop your science-based target consult the SDA tool, methods and resources pages. For more information please read our FAQs.

Please note that the SBTi has launched a paid target validation service that provides a faster assessment time and more in-depth feedback from SBTi technical reviewers. This paid service is applied to all companies submitting targets for validation (as of February 2019). Please see our FAQs (Section E) for more details on this offering, including eligibility for fee exemptions.

Step 3: Submit your target for validation


Once a target has been developed, your company must complete the ‘Target Submission Form’ and submit a Word version of the form via email to [email protected]

The target validation service, a paid service offering that provides a faster assessment time and more-in-depth feedback from SBTi technical reviewers, is mandatory beginning February 2019 for official and preliminary validations.

The target validation service costs USD 4950 (+ applicable VAT), which includes up to two target assessments (companies can choose between one preliminary and one official, or two official validations).

Subsequent resubmissions cost USD 2490 (+ applicable VAT) per submission. Please note that resubmissions only include one target assessment (preliminary or official). The resubmission price is available to companies that 1) have submitted at least once using the paid target validation service, 2) already have approved targets but need to update them, and/or 3) were approved through a preliminary validation under the free service.

The cost of the target validation service can be waived for companies headquartered in developing countries and economies in transition. For more information please see our FAQs (Section E).

The Science Based Targets team will then verify the target against the SBTi criteria and inform you whether the target has been formally approved or if it needs additional work. The SBTi has developed additional guidance and clarifications relating to version 3.0 of the Science Based Targets initiative’s target validation criteria.

We encourage you to read the Target Submission Form guidance’ for support to fill out the form correctly, and ensure you are using the latest version (2.3) of the Submission Form.

Step 4: Announce the target

On confirmation that your target meets the SBTi criteria your company and its target will be showcased on the Science Based Targets website and in other communications and you will be able to use our logo on your website and communications. You will be sent a communications welcome pack and will be able to liaise with a member of the team.




Join the Net-Zero by 2050 Team

Once a company has committed to setting a science-based target, they are encouraged to also further pledge to phase out all greenhouse gas emissions by January 1, 2050 and join the Net-Zero by 2050 team.

The Net-Zero 2050 Team is a leadership group of CEOs and their companies, who are working together to accelerate the just transition to net-zero greenhouse gas emissions by 2050. The pledge is formally recognised as part of the We Mean Business coalition’s Take Action campaign and is led by the B-Team in collaboration with the SBTi.
