3Cs models that will change how you talk about sustainability

In this Episode of Spill the (Green) Tea, Katie and Malin speak about how to communicate sustainability clearly, credibly, and without getting called out sharing their two different (but surprisingly aligned) 3Cs frameworks for navigating climate communications. Together, they unpack what it really takes to build trust, avoid greenwashing, and bring audiences with you on the journey, not just at the finish line.

In this episode, we cover:

• Why clarity and action must come before communication
• Two practical 3Cs frameworks for stronger sustainability messaging
• How transparency and progress build trust, even when things aren’t perfect yet
• The shift from vague claims to confident, specific communication
• How to structure and layer your messaging so it actually lands

This episode is a practical deep dive into what responsible sustainability communication actually looks like and how it’s rooted in clarity, action, and honesty.
