Diane Millis

Strategic communications leader for climate, nature and sustainability.

I provide communications leadership, strategic counsel and delivery expertise to organisations doing ambitious work in these sectors.

I began my career in business journalism, developing the curiosity, judgement and audience instinct that still underpin my approach to communications – getting quickly to the heart of complex subjects and finding the story that matters.

My experience spans in-house leadership and consultancy, working with climate technology companies, non-profits, standards bodies, project developers and accelerators across climate and nature. My work has covered carbon markets, carbon capture and storage, regenerative agriculture, forestry, biodiversity and blue carbon – shaping narratives and communications strategies, raising organisational and executive profiles, developing thought leadership, and leading media, content and wider communications programmes.

I work across advisory and project briefs as well as fractional communications leadership. Where a project needs additional expertise or capacity, I can bring together and lead a trusted team of communications specialists, giving clients the flexibility to scale around what they actually need.

Whatever the model, I bring the same combination of strategic thinking, creativity and momentum – turning good ideas and expertise into communications that get noticed and make an impact.
