Failure to assess and address climate risk is a failure of fiduciary responsibility.
Failure to disclose *known* material risks to physical locations, infrastructure & supply chains is fraud.
Deliberately avoiding assessing risks to avoid uncomfortable disclosure ... is malfeasance.

That’s why I’m excited about @wbcsd.bsky.social's Global Circularity Protocol for Business (GCP), a science-based, voluntary framework that helps companies measure, manage, and communicate circularity with standardized steps and metrics across value chains.

In my recent piece as a Forbes Councils member on Forbes.com, I wrote on what I’m hearing from executives: climate leadership is no longer “nice to have” — it’s becoming a core driver of business success.
But... you can’t manage (or finance) what you can’t measure.

Where is your organization seeing the strongest climate-to-value connection right now? Is it risk reduction, cost savings/efficiency, revenue/innovation, talent, or access to capital? I’m always interested in how leaders are measuring progress and what’s actually moving the needle.

The biggest shift I’m seeing: “ROI” is expanding from short-term returns to long-term value creation, and climate leadership is becoming one of the ways organizations prove they’re built to endure and grow.
