Our Heritage: 20 Years of Independent Indexing

Global 100 began at the World Economic Forum in Davos in January 2005 as the Global 100 Most Sustainable Corporations in the World. It became one of the most-cited corporate sustainability rankings of the 2000s and 2010s, evaluating publicly-traded companies across measurable environmental, social, and governance criteria. Fifteen annual cycles established a body of practice: quantitative methodology, public criteria, annual publication, independent scoring.

In 2026, the franchise pivoted. The questions had changed. The fastest-moving threat to institutional trust was no longer corporate sustainability disclosure. It was the rise of synthetic media: AI-generated text indistinguishable from human writing, voice clones indistinguishable from real callers, deepfake images indistinguishable from photographs. The institutions that buy detection tools, universities, newsrooms, financial services, government agencies, needed the same thing they had needed from sustainability rankings: a rigorous, independent, methodologically transparent way to compare vendors.

The 2026 Global 100 AI Content Integrity Index is the result of that pivot. The methodology is new but the principles, public criteria, blind testing, annual cadence, no pay-for-placement, are continuous with the original. The team applies twenty years of indexing discipline to a domain that did not exist a decade ago.

What Stays the Same

The pivot from corporate sustainability to AI content integrity changed everything about the data we collect, but nothing about how we collect it. Four commitments carry forward from 2005 to 2026:

What Changed

Three things had to be rebuilt from scratch for the 2026 edition. The first was the test corpus: corporate sustainability data was self-reported through public filings; AI detection had to be tested against blind, controlled inputs that vendors could not see in advance. The second was the KPI set: sustainability metrics (resource productivity, board diversity) gave way to detection accuracy, false positive rate, model coverage, and transparency. The third was the audience: institutional investors gave way to procurement officers at universities, IT teams at publishers, and compliance leads at financial-services firms.

The shared discipline made the pivot feasible. Twenty years of operating an annual quantitative ranking is twenty years of learning how to design measurement protocols that vendors cannot game, how to communicate methodological choices to non-technical audiences, and how to publish results that withstand peer scrutiny. Those skills do not transfer perfectly across domains, but they transfer better than starting from zero.
