The Crux Files

Print Friendly

Crux is about supporting sustainability leaders – that’s you! – in being more effective change agents, and doing so in a compassionate, fun, engaging and irreverent way.

I started this blog because I felt that the vast majority of sustainability communication is either missing in action (not happening), missing the mark (not hitting the target audience/s in a way that resonates) or missing the point (focusing on the wrong thing).

So much of our sustainability communications is the equivalent of shouting loudly at someone who does not speak our own language. Becoming ever more strident, earnest, or scary is not going to create the shift.

If people aren’t getting it, that’s not their fault – its OUR fault, because its our responsibility to frame and communicate our messages so they resonate.

This blog is no longer being posted to regularly (though I still post to the Crux Facebook page), however there is 2-3 years’ worth of material that remains relevant and useful.

Here are some of the best offerings from Cruxcatalyst, including guest posts, on values, interpersonal communication, psychology, leadership and more. Use the drop down arrows to the right of this page under ‘Crux Files’ to explore this repository fully.
