Green Monday is a Hong Kong social venture that tries to move climate, animals and health at once, from the small step of 'cut meat one day a week.' In 2012, the Buddhist vegetarian David Yeung launched it as a Meatless Monday-style movement against livestock farming's huge carbon emissions, burden on animals and health risks. Its banner: 'make more than half of Monday's meals plant-based; then make it 5 days, then 7'—not forcing full veganism, but a form anyone can lean toward plant-centered. The movement spread to over 100 countries, partnering with over 800 schools and companies. Under it are the Green Monday Foundation (the movement), the plant-based retail/dining Green Common, the food tech OmniFoods (which released Asia's first plant pork, OmniPork, in 2018, reaching over 25,000 points of sale across 7-plus regions), and Green Monday Ventures, an early investor in Beyond Meat. Reducing livestock farming is one of the most effective climate actions an individual can take, and in Hong Kong—one of the world's top meat-consuming places—the company says it moved 30–40% of people toward flexitarianism. David Yeung is an Ashoka Fellow.

Main narrative
One person’s story (N1)
+ A single story
Livestock farming emits vast greenhouse gases and also carries problems of animal welfare and antibiotic overuse. Green Monday spread 'make more than half of Monday's meals plant-based' to over 100 countries and 800-plus schools and made meat substitutes familiar with OmniPork and the like. Cutting meat and dairy is one of the most effective climate actions an individual can take. The benefit appears not as an individual name but as a collective, systemic effect—animals spared breeding/slaughter through reduced demand, and greenhouse gases avoided (Nature, Animals).

A second look
The plus is reduced climate burden from cutting livestock farming (Nature) and animal welfare (Animals) plus public health (People), backed by a movement in over 100 countries, over 800 schools and Ashoka Fellow status. But it is a commercial food-tech/retail business that also takes VC funding, ultra-processed plant-based foods have health/nutrition debates, the net plus—amount of meat reduced, emissions and animal numbers actually avoided—is diffuse and hard to verify, and '30–40% flexitarian' is a survey-based claim. The N1 is systemic—animals saved and emissions avoided through reduced demand—rather than a person.

How to read this assessment
- Reachable upper bound (ceiling): a confirmed − sets the ceiling, and independently verified + decide the position within it. + do not cancel out −.
- The weight of evidence is not symmetric: only confirmed − are counted; the volume of disputes or allegations goes under “Watching.” + are counted from independent evidence, while an organization’s own PR is treated as “reference.”
- Size is not value: scale is not used in the assessment. Matters that stay within money or competition—investors, shareholders, sanctions, trade secrets—are also excluded.
- The letter (assessment) and certainty (how reliable the information is) are separate axes.
This is a translation; the Japanese version is authoritative. The assessments here are generated automatically by AI based on published criteria. The operator does not alter individual results. Because they are AI-generated they may contain errors, and they are opinion and commentary, not statements of fact. Where evidence is insufficient, the entry is marked “On hold.” Requests for correction are accepted via the form.
Terms: Narrative Value = an assessment (A–G) of the distance between the story an organization tells and its reality / Ceiling meter = a visualization of the reachable upper bound / Watching = unconfirmed matters not counted / Protected stakeholders = people, animals, nature, and future generations. | Generated by: AI | As of: 2026-Q3 | Back to top
