Is incrementalism enough in a systems-change world?

Are sustainability professionals working at the wrong level inside a system that resists real change? Joel and Soli dig into that question this week — why external validation is the wrong thing to chase, what a "hero's journey" framework does and doesn't explain about doing this work, and why renewable energy's transformation over one lifetime is the best evidence that incremental effort compounds. Plus, a quick update on the "spheres of influence" framework, now headed toward a forthcoming ISO net-zero standard.
