The report, Hearth and Hiraeth: Constructing Climate Change Narratives around National Identity draws on the findings of a major programme led by Connect4Climate's partner COIN for the Welsh Government. This programme developed language and narratives that could work with all social groups and be applied in all its communications.

The two-year programme built on the latest research into climate change attitudes and a detailed analysis of cultural values. It conducted rigorous testing of messages in groups that had been recruited according to a values-based segmentation model. It is one of the first programmes in the world to apply the research into values-based climate communications across an entire country.
