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” at https:// 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.

Step 3: Submit your target for validation

Once a target has been developed, your company must complete the ‘Target Submission Form’ and submit it via email to [email protected]. We encourage you to read the Target Submission Form guidance’ for support to fill out the form correctly. 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. For more information on the target validation service, including associated costs, please read our FAQs.

Companies submitting their targets should ensure they use the latest version of the submission form and guidance, both available in this page. Note that starting from April 16th 2018, all companies must use version 2.2 of the Target Submission Form.

Step 4: Announce the target

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.
