Communicating sustainability well can create real buy-in and drive engagement and action. And it isn’t just about what you say - it’s about how people think, feel, and behave (especially the last one). This three-part Communicating Sustainability series from Sustainability 360 brings together insights from psychology, communication, and change management to help sustainability leaders connect with people in ways that inspire action and long-term change.
- The first session, Communicating Sustainability, Caroline Thalund explored how to talk about sustainability clearly and authentically - avoiding greenwashing and greenhushing while telling stories that connect both emotionally and rationally. Guest expert Jo Scott shared lessons from journalism and corporate communication on how to simplify complex ideas, use storytelling effectively, and make sustainability part of everyday dialogue.
- In the second session, Internal Communication for Impact, Caroline focused on building genuine engagement inside the organisation - using behavioural psychology and change-management techniques to move from isolated effort to shared responsibility. With guest expert John Eatwell, participants learned how to design communication and systems that motivate people, form habits, and make sustainability part of daily routines.
- This final fireside chat with Dr Niki Harre brings the series together by delving deeper into the psychology of engagement – why people act (or don’t) on sustainability, how peer influence drives behaviour change, and how to make new habits stick.
Join business sustainability specialist and Professor of Practice at the University of Canterbury, Caroline Thalund, in conversation with Dr Niki Harre, Professor of Psychology and Head of School at the University of Auckland. Together they unpack what really drives engagement with sustainability across an organisation – from leadership influence to peer networks and workplace culture.
They discuss:
- Why sustainability must be embedded across the whole organisation – not siloed in one department
- How to balance top-down leadership support with bottom-up energy from champions and peers
- Practical ways to maintain momentum, form new habits, and prevent burnout among sustainability leaders
- How to make sustainable behaviours part of everyday systems, processes, and culture
