illuminem is proud to present the most-read Thought Leaders in Sustainable Lifestyle globally, as recognised by illuminem's ever growing community of 700,000+ readers.

The sustainable lifestyle conversation in 2025 was defined by a question of culture rather than policy: whether the stories, images, and habits that shape how people live could survive a year in which climate messaging itself came under attack. As ESG became a political liability and corporate commitments frayed, the communications and creative industries found themselves on the front line. The campaign by Clean Creatives to push advertising and PR agencies away from fossil-fuel clients put a spotlight on the role of marketing in climate delay, while a parallel reckoning over greenwashing forced brands to reconcile the gap between what they said and what they did.

What emerged was a recognition that behavior change cannot be legislated into being. The attitude-behavior gap – consumers who say they want sustainability but rarely buy it – remained the central puzzle, and the voices on this list approached it from culture, psychology, and design rather than regulation alone.

Kasper Benjamin Reimer Bjørkskov, founder of No Objectives, topped this list by turning that puzzle into method. An architect by training, he treats branded activism as a tool to convert minority insight into majority action, integrating marketing with social and environmental causes to spark systemic change. His most-read piece made the case for doing first and believing later – that action, not conviction, is where change begins.

Joining him on the list, Gloria Benedikt explores what happens when theatre becomes a climate issue, Mikaela Loachbrings intersectional climate and racial justice to a mass audience, and Bill McKibben, co-founder of 350.org and one of the movement's founding voices, anchors the case that communication shapes who acts and when.

Drawn from over 2,500 thought leaders publishing on illuminem Voices, the ranking below reflects the voices that shaped how the sustainable lifestyle conversation evolved in 2025. Please join us in congratulating the Thought Leaders of the Year in Sustainable Lifestyle, and every voice contributing to this vital global debate on illuminem.
