Business Ambition for 1.5°C

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.
