What the IPCC report means for non-executive directors

The UN Intergovernmental Panel on Climate Change (IPCC) has completed its Sixth Assessment Report (AR6). With the IPCC's next report expected around 2030, this is likely to be its last assessment report published in this critical decade for climate action.

As part of AR6, four important reports containing the latest scientific knowledge on climate change have been released since August 2021, with the last in March 2023.

Here are the key takeaways are for NEDs:

1. Limiting global warming to 1.5°C above pre-industrial levels is still achievable but requires immediate, rapid, and large-scale reductions in greenhouse gas emissions.
   • Board directors play an important role in ensuring the organisations they represent set, and deliver upon, ambitious climate targets and transition plans.
2. The report provides unequivocal evidence of the link between human activity and global warming. It highlights the devastating risks and impacts for people and nature, including material risks for business.
   • Board directors should consider these risks and impacts for the businesses (and broader value chains) they oversee, disclose the findings, and put in place appropriate measures to address them.
3. The cost of inaction is likely to be much higher than the cost of action to limit warming to 1.5°C in the medium to long-term.
   • Bold climate leadership today, both to reduce emissions and adapt to the impacts of climate change, will serve long-term business interest.
