She went vegan around age ten, then told her mother and father, both accomplished professionals, that they were &ldquo;stealing our future&rdquo; and couldn&rsquo;t credibly stand up for human rights while eating the way they did. They caved. Her father went fully vegan; her mother, an opera singer, largely followed.<\/p>\n<p>That&rsquo;s the thing to understand about &ldquo;is Greta Thunberg vegan&rdquo;: for her it was never a lifestyle choice separate from the climate fight.

Recent years have centered her activism on other causes, but nothing suggests the diet has changed.<\/p>\n<p class=\"tiv-check\">Last fact-checked: July 7, 2026<\/p>\n<\/div>\n<h2>The math she keeps repeating<\/h2>\n<p>Greta&rsquo;s case for veganism is a number, not a feeling. From her 2021 Mercy For Animals film For Nature: &ldquo;If we change towards a plant-based diet, we could save up to eight billion tonnes of CO2 every single year.&rdquo; She&rsquo;s framed animal agriculture as one of the biggest, most avoidable drivers of the crisis she&rsquo;s spent her life shouting about, and she doesn&rsquo;t soften it. The film&rsquo;s most-quoted line is unprintable in full, but it rhymes with &ldquo;if we don&rsquo;t change, we are finished.&rdquo;<\/p>\n<p>She also turned it into one of the sharpest animal-welfare lines from any climate figure: &ldquo;Every year we kill more than 60 billion animals, excluding fish, whose numbers are so great that we only measure their lives by weight. What about their thoughts and feelings?&rdquo;<\/p>\n<h2>The vegan timeline, tap to expand<\/h2>\n<details class=\"tiv-tl\">\n<summary>Around 2013: vegan at ten<\/summary>\n<div class=\"tiv-tlb\">She goes vegan as a child. Sources vary slightly on the exact year, so call it &#8220;her early teens, mid-2010s.&#8221;<\/div>\n<\/details>\n<details class=\"tiv-tl\">\n<summary>The family conversion<\/summary>\n<div class=\"tiv-tlb\">She pressures her parents to go plant-based and to stop flying. Her mother's international opera career ends as a result. That's how seriously the household took it.<\/div>\n<\/details>\n<details class=\"tiv-tl\">\n<summary>August 2018: the strike<\/summary>\n<div class=\"tiv-tlb\">She begins her school strike outside the Swedish parliament, launching Fridays for Future.<\/div>\n<\/details>\n<details class=\"tiv-tl\">\n<summary>2019: &#8220;How dare you&#8221;<\/summary>\n<div class=\"tiv-tlb\">Her UN Climate Action Summit speech makes her a global figure.<\/div>\n<\/details>\n<details class=\"tiv-tl\">\n<summary>2021: For Nature<\/summary>\n<div class=\"tiv-tlb\">She writes and narrates the Mercy For Animals film explicitly linking animal agriculture to the climate crisis and calling for a plant-based shift.<\/div>\n<\/details>\n<details class=\"tiv-tl\">\n<summary>2025: a new front<\/summary>\n<div class=\"tiv-tlb\">Her public activism broadens to humanitarian causes. Coverage shifts, but her biography still lists her as vegan, and no reversal exists.<\/div>\n<\/details>\n<h2>An honest note on recency<\/h2>\n<p>We check these things properly, so here&rsquo;s the caveat: Greta hasn&rsquo;t given a fresh, dated 2025 or 2026 quote re-confirming &ldquo;I am vegan.&rdquo; Her recent headlines are about other activism. Our &ldquo;still vegan&rdquo; verdict rests on a long, consistent record, her current biography stating it, and the complete absence of any &ldquo;quit&rdquo; news. That&rsquo;s a strong case, and we&rsquo;ll flag it honestly rather than invent a quote she didn&rsquo;t give.<\/p>\n<h2>Fact or fiction?<\/h2>\n<details class=\"tiv-tl\">\n<summary>She convinced her parents to go vegan.

Aus S\u00fcddeutschland, besser gesagt aus dem Schwarzwald, seit 2019 Gr\u00fcnder von This Is Vegan, mittlerweile in Bali zuhause. Von hier aus treibe ich Tierschutzprojekte voran und reise um die Welt. Vegetarier bin ich seit dem 6. Lebensjahr, vegan seit \u00fcber 20 Jahren. Mein Ansatz war nie, Leuten ein schlechtes Gewissen zu machen. Sondern zu zeigen, wie einfach, lecker und entspannt vegan im Alltag funktioniert. Anziehung statt Ablehnung. Genau daf\u00fcr gibt's dieses Online-Magazin und den Plantbased Podcast: Menschen inspirieren, sich f\u00fcr Tiere und Umwelt stark zu machen und vegan zu leben.","sameAs":["https:\/\/www.this-is-vegan.com","https:\/\/www.instagram.com\/yannick.haldenwanger\/","https:\/\/www.linkedin.com\/in\/yannickhaldenwanger\/","https:\/\/www.pinterest.de\/thisisvegan_magazin\/","https:\/\/www.youtube.com\/@thisisvegan"],"knowsAbout":["vegane Ern\u00e4hrung","holistische Gesundheit","Ern\u00e4hrung","vegane Rezepte","Kampfsport","Kraftsport","Proteine"],"knowsLanguage":["deutsch","englisch","franz\u00f6sisch","indonesisch"],"jobTitle":"Gr\u00fcnder","url":"https:\/\/this-is-vegan.com\/en\/author\/yannick\/"}]}},"_links":{"self":[{"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/posts\/40654","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/comments?post=40654"}],"version-history":[{"count":1,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/posts\/40654\/revisions"}],"predecessor-version":[{"id":40674,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/posts\/40654\/revisions\/40674"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/media\/40653"}],"wp:attachment":[{"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/media?parent=40654"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/categories?post=40654"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/tags?post=40654"},{"taxonomy":"ernaehrungsform","embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/ernaehrungsform?post=40654"},{"taxonomy":"schwierigkeit","embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/schwierigkeit?post=40654"},{"taxonomy":"schaerfe","embeddable":true,"href":"https:\/\/this-is-vegan.com\/en\/wp-json\/wp\/v2\/schaerfe?post=40654"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
