"Become" here means it only counts if they switch from being non-vegan to being vegan, not if they were already vegan at market creation or taking office. Returning to veganism only counts if they were non-vegan for >1y.

"Vegan" here covers both identifying as such without the actual lifestyle changes and making the lifestyle changes without identifying as such. Trace amounts of animal products in goods and services they purchase or use are allowed, but it cannot account for >1% of product mass, volume, or surface area. Unknowingly or unwillingly using animal products does not disqualify them.

• Update 2025-12-29 (PST) (AI summary of creator comment): For verification purposes:

  • Reliable sources will be those listed on Wikipedia's Perennial Sources page as generally reliable (e.g. ABC, BBC)

  • For the 1% threshold: In most cases it will be clear cut based on the nature of the product. In disputed grey areas, threshold-passing may be estimated from ingredients of the most similar products available online
