Join the 1.5°C business leaders
Business Ambition for 1.5°C is an urgent call to action from a global coalition of UN agencies, business and industry leaders, in partnership with the Race to Zero.
We’re calling on companies - across all sectors and geographies - to set science-based net-zero aligned emissions reductions targets.
By signing up to the Net-Zero Standard and committing to set a target in line with a 1.5C and net-zero future - our only future - your company can make its critical contribution to limiting the worst impacts of climate breakdown.
Why 1.5C and Net-Zero
The IPCC’s Sixth Assessment report was ‘code red’ for humanity.
It showcased the need for urgent climate action to maintain a habitable planet for humankind.
To avoid the most significant effects of climate breakdown, we must halve greenhouse gas emissions before 2030, achieve net-zero emissions before 2050 and halt global temperature rise to 1.5°C.
That’s why we are inviting all business leaders to publicly commit their companies to a science-based net-zero and 1.5°C target, and join the Race to Zero.
Your leadership on climate action starts now.

For companies with existing science-based targets, we encourage you to boost the ambition level of your current targets and align your scopes 1 and 2 ambition, along with scope 3 where relevant, with a 1.5°C and net-zero pathway. Learn more.

Frequently asked questions
The SBTi has translated the scenarios and pathways underlying the IPCC Special Report on 1.5°C into a set of resources that companies can use to model 1.5°C-aligned targets. This includes a technical paper providing details about how IPCC SR15 pathways are being used by the SBTi to inform our target-setting criteria and validations protocols, and a science-based target setting tool.
Companies that have already publicly announced their commitment to reach net-zero emissions before 2050 are strongly encouraged to commit to set a net-zero target aligned with the SBTi Net-Zero Framework and join the Business Ambition for 1.5°C. By doing so, companies ensure their net-zero commitments follow the necessary scientific rigour to deliver the necessary decarbonization.
Without a common science-based definition of what constitutes a net-zero target, companies and stakeholders cannot be sure their long-term climate targets are credible or ambitious enough.
Additionally, by joining the campaign, companies are using their influence to incentivize other companies to follow suit and national governments to set supportive policies and targets for a net-zero emissions economy.
Join the business leaders taking ambitious climate action
On 19 October 2021, the SBTi's #ClimateActionDay saw over 750 companies from across more than 10 countries worldwide come together to celebrate ambitious 1.5°C-aligned climate action.
The day successfully showcased far-reaching and significant corporate support for bold 1.5°C-aligned climate action ahead of COP26.
In 2017, we became the first company globally to set new, science-based targets in line with the 1.5 degree trajectory recommended in the Paris Climate Accord. Jason Tarry Tesco UK and ROI CEO
