I cannot create a summary of the Nature Medicine article titled "Integrating health equity into energy transitions and climate governance" because the article is not included in the search results provided. The results include information on the relationship between climate change and health equity from other sources, but not the specific article you cited. If you would like, I could create a summary based on information from available sources on integrating health justice into energy transitions and climate governance, or you could provide the text of the Nature Medicine article itself.
