We urgently need to act on climate change and limit global warming to 1.5°C.
Join the visionary corporate leaders who are taking ambitious action.
Set a science-based target in line with a 1.5°C future.
‘Business Ambition for 1.5°C’ is an urgent call to action, led by a global coalition of UN agencies, business and industry leaders. We’re calling on companies to commit to ambitious emissions reduction targets through the Science Based Targets initiative (SBTi). By setting a science-based target in line with a 1.5°C future, businesses can make their critical and necessary contribution to limiting the worst impacts of climate change. So far, 311 companies, representing over $3.6 trillion in market cap, have responded to the open letter and signed the Business Ambition for 1.5°C commitment.Join the 1.5°C business leaders
Why 1.5°C?
To hold off some of the worst climate impacts, and avoid irreversible damage to our societies, economies and the natural world, we must hold temperature rise to 1.5°C above pre-industrial levels. This requires halving greenhouse gas emissions by 2030 and hitting net-zero emissions by 2050.
That’s why we are inviting visionary business leaders to publicly commit their companies to a 1.5°C target and be recognized in the lead up to COP 26 in November 2021. Leading companies are already proving that a 1.5°C-compliant business model is possible, and there is evidence that these companies will be best-placed to thrive as the global economy undergoes a just transition to a net-zero future by 2050.
Your leadership on climate action starts here.
