One of the messages emerging from @wbcsd.bsky.social’s #BusinessBreakthroughBarometer is that companies increasingly view climate-related disruption as an operational and business planning challenge. I’d love to hear from this community. Please respond here: www.linkedin.com/posts/wsisso...

America's 250th reminds us that the most important progress is built through conviction sustained over time. At @wbcsd.bsky.social, we see the same: businesses defining the next century embed resilience and sustainability into everything they do. Happy Fourth of July!

I spoke about how the rules of business performance are changing. Increasingly, companies are being evaluated not only on cost, quality, and delivery, but also on their ability to manage risk, build resilience, provide transparency, and adapt in a more complex operating environment.

I’m excited to share my op-ed published in @reuters.com this week, where I wrote about something I’ve seen repeatedly: when companies stay true to their values, they outperform those who don't.
