Business Ambition for 1.5°C

The Business Ambition for 1.5°C campaign is now closed. The campaign enabled companies to set robust science-based targets, and reduce emissions at the pace and scale required by climate-science. Endorsed by an unprecedented global coalition of UN agencies, business groups and industry leaders, the campaign provided a clear pathway for businesses to become credible climate leaders.


Business Ambition for 1.5°C’ is an urgent call to action from a global coalition of UN agencies, business and industry leaders. We’re calling on companies to commit to set ambitious science-based emissions reduction targets. By setting a net-zero target in line with a 1.5°C future — our only future — businesses can make their critical contribution to limiting the worst impacts of climate change.
