Business Ambition for 1.5°C

The 1.5°C business leaders

The Business Ambition for 1.5°C campaign was an urgent call to action from a global coalition of UN agencies, business and industry leaders, in partnership with the Race to Zero.

More than 1000 companies committed to the Business Ambition for 1.5°C campaign. These companies represent over $23 trillion in market capitalization, more than the GDP of the United States.

The campaign closed in November 2021. Companies can still join the Race to Zero by signing up to the Net-Zero Standard and committing to set a target in line with a 1.5°C and net-zero future.
