Please participate in the first annual State of Corporate Adaptation survey – we need your input!

• How are global corporations preparing for climate change impacts?
• What are the most pressing climate risks for your sector?
• How are your competitors planning for extreme weather events?
• What climate impacts should you be monitoring and why?

These are some of the questions at the heart of our research. Click here to add your voice to this timely discussion.

The first annual State of Corporate Adaptation was recently launched by Four Twenty Seven, in partnership with the University of Notre Dame Global Adaptation Index (ND-GAIN) and with support from Business for Social Responsibility (BSR).

Survey results and analysis – including best practices in corporate adaptation practices - will be released in a public report in May 2015. Your participation is greatly appreciated and will help us advance this critical issue.
