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. 

After submitting your commitment letter, 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.

Which commitment letter should you sign?

  • Companies are invited to sign the Standard Commitment Letter.
  • However, we encourage all companies to commit to the highest level of ambition possible by signing the Business Ambition for 1.5°C Commitment Letter instead. This indicates a commitment to set a target in line with limiting global warming to 1.5°C (please see details here and learn more about the Business Ambition for 1.5°C campaign here).
  • 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.

The SBTi reserves the right to carry out due diligence reviews before accepting signed commitment letters. This applies to all SBTi commitments including those received through the Business Ambition for 1.5°C campaign.


Step 2 : Develop a target

Once your company has signed the commitment letter you will have up to 24 months to get your target(s) validated and published

For the best chance of approval you should ensure that your target meets the SBTi’s target setting criteria. The latest SBTi Criteria (4.0) offers companies two temperature goal options, 1.5 degrees and well-below 2 degrees, and your submission should meet the criteria for the goal specified in your Target Submission Form. Until October 2019, companies wanting to set targets in line with 2 degrees can continue to use the SBTi Criteria (3.0), and the additional guidance and clarifications created to support it. From October, these resource will no longer be available and companies will have to set targets against the 1.5°C or well-below 2°C criteria.

For more information  on the science-based target setting process, please visit our methods, resources and FAQs pages.

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 costs USD 4950 (+ applicable VAT), which includes up to two target assessments. Subsequent resubmissions cost USD 2490 (+ applicable VAT) per submission.

Please note that resubmissions only include one target assessment. 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.

We encourage you to read the SBTi criteria and Target Submission Form guidance’ prior to submitting your target. A full list of resources can be found on our Resource page.

Step 4: Announce the target

For non-SMEs: On confirmation that your target meets the SBTi criteria, your company and its target will be showcased on the SBTi website and in other communications and you will be able to use the SBTi logo on your website and in company communications. You will be sent a communications welcome pack and will be able to liaise with a member of the SBTi communications team.

Targets submitted through the dedicated route for SMEs will be automatically approved and posted to the SBTi website, pending due diligence review and payment. Companies will be sent a communications welcome pack and will be able to use the SBTi logo on their website and in company communications.


Upgrade your target

In response to the special report from the Intergovernmental Panel on Climate Change (IPCC) on 1.5°C released in 2018, the SBTi introduced new criteria and resources to enable companies to set targets consistent with the most ambitious aim of the Paris Agreement, to limit global warming to 1.5°C above pre-industrial levels. The criteria also allow targets in line with limiting warming to well-below 2°C.

We invite companies to voluntarily boost the ambition level of their current targets and align your scopes 1 & 2 ambition with a 1.5°C or well-below 2°C pathway. A straightforward and cost-free option is available for companies to upgrade their ambition if their targets are currently 2°C or  well-below 2°C aligned. Companies can use this cost-free option if they meet the following conditions:

  1. Base year and target year of the updated target remains unchanged;
  2. Assumptions used to model the original target remain valid (e.g. significance thresholds, boundary, growth projections, etc.)

Please refer to the SBTi Target Validation Protocol for more information. To use this simplified process, please complete and submit this form to [email protected].

For those companies upgrading their targets to align with the most ambitious temperature alignment, you can also publicly showcase your commitment by signing the Business Ambition for 1.5°C commitment and supporting the global call to limit global temperature rise to 1.5°C.
