When Greta Thunberg became the world’s most famous climate activist, her father Svante Thunberg was thrust into an unexpected spotlight. Born in 1969 in Stockholm, this Swedish actor and producer had lived a relatively quiet life in Sweden’s entertainment industry before his daughter’s school strike changed everything. Married to renowned opera singer Malena Ernman, Svante’s journey from private citizen to public figure represents one of modern parenting’s most extraordinary stories.
The transformation began when the Thunberg family faced a personal crisis—Greta’s severe depression and climate anxiety in 2014-2015. Rather than dismissing her concerns, Svante and Malena listened, made radical lifestyle changes, and ultimately supported their daughter’s decision to strike from school. Today, at 56 years old, Svante balances his roles as protective father, climate advocate, and co-author of the family’s bestselling memoir while navigating the complexities of raising a global icon.

Who is Svante Thunberg?
Svante Fritz Vilhelm Ernman Thunberg is a Swedish actor, author, and producer born in 1969 in Stockholm, Sweden. Before becoming known as “Greta’s dad,” Svante had carved out a respectable career in Sweden’s entertainment industry, appearing in various television shows and theatrical productions. His life took an unexpected turn when his eldest daughter decided to skip school and sit outside the Swedish Parliament with a handmade sign reading “Skolstrejk för klimatet” (School Strike for Climate).
Svante Thunberg Age
As of December 2025, Svante Thunberg is 56 years old. Born in 1969, he has spent more than half his life in Sweden’s cultural scene, though the past seven years have dramatically shifted his public profile from regional actor to internationally recognized figure in the climate movement.
Svante Thunberg Wife: Malena Ernman
Svante is married to Malena Ernman, one of Sweden’s most celebrated opera singers. Malena represented Sweden in the 2009 Eurovision Song Contest and has performed at prestigious venues worldwide, including the Royal Opera in Stockholm. The couple’s marriage represents a union of two artistic souls, both deeply committed to their crafts and, more recently, to environmental activism.
Their relationship has been tested in extraordinary ways. When the family decided to stop flying due to aviation’s climate impact, Malena’s international opera career took a significant hit. Opera singers typically travel globally for performances, and eliminating air travel meant turning down lucrative opportunities. Yet both parents made this sacrifice, demonstrating their commitment to living according to their climate convictions.
Svante Thunberg Net Worth
Estimating Svante’s exact net worth is challenging, but various sources suggest it ranges between $1 million to $3 million USD. This wealth comes from multiple sources:
- His acting career in Swedish television and theater
- Producer credits in Swedish entertainment
- Royalties from “Our House is on Fire” (2020), the family memoir that became an international bestseller
- Speaking engagements and public appearances
- His wife Malena’s successful opera career
It’s worth noting that the Thunberg family has been transparent about not profiting from Greta’s activism. They’ve repeatedly stated that Greta’s climate work is volunteer-based, and they’ve turned down numerous commercial opportunities that would have capitalized on her fame.
Early Career: Actor and Producer
Before climate activism consumed his family’s life, Svante enjoyed a steady career in Swedish entertainment. He appeared in “Skärgårdsdoktorn” (The Archipelago Doctor), a popular Swedish TV series, among other productions. His work was respected within Sweden’s tight-knit artistic community, though he never achieved household name status.
His background in storytelling and performance would later prove invaluable when helping his family navigate intense media scrutiny. Understanding camera angles, interview dynamics, and narrative construction gave Svante tools to protect his daughters while managing their unprecedented public exposure.
The Family Crisis That Changed Everything
The Thunberg family’s transformation began around 2014-2015 when Greta, then 11 years old, learned about climate change in school. The knowledge devastated her. She became depressed, stopped eating, stopped speaking except to her immediate family—symptoms of what would be diagnosed as Asperger’s syndrome, OCD, and selective mutism.
Svante and Malena watched their daughter suffer profoundly. “She stopped eating. She stopped speaking,” Svante has recalled in interviews. Greta lost about 10 kilograms in two months, a terrifying time for any parent. The family sought medical help, therapy, and searched desperately for ways to help their daughter find hope again.
What changed everything was when the family decided to listen to Greta. She explained that her climate anxiety stemmed from the disconnect between the severity of the climate crisis and adults’ minimal response. The family began making radical lifestyle changes: going vegan, stopping flying, reducing consumption. These weren’t just symbolic gestures—they represented the family living according to the urgency Greta felt.
Supporting an Unlikely Activist
When 15-year-old Greta announced in August 2018 that she would strike from school until Sweden aligned its policies with the Paris Agreement, Svante was initially worried. What parent wouldn’t be concerned about their child sitting alone outside Parliament instead of attending school?
But he and Malena made a crucial decision: they would support Greta’s autonomy. “We thought it was a bad idea, frankly,” Svante has admitted. But they recognized this was Greta’s decision, and opposing it might damage her fragile mental health recovery.
What began as a lonely three-week protest before Sweden’s 2018 elections exploded into a global phenomenon. Within months, millions of young people worldwide were participating in Fridays for Future strikes, inspired by one Swedish teenager’s courage.
Transatlantic Voyages and Family Sacrifice
Perhaps no moment better illustrated the family’s commitment than Greta’s trips across the Atlantic Ocean to attend UN climate conferences. In August 2019, Svante accompanied Greta on a two-week sailing journey aboard a zero-emissions yacht from Plymouth, England to New York City. The voyage was uncomfortable, occasionally dangerous, and involved seasickness and cramped conditions.
They made the journey again in December 2019, sailing from Virginia to Portugal. These weren’t publicity stunts—the family genuinely refused to fly, even when it meant weeks of difficult travel instead of hours in an airplane. Svante’s presence on these journeys demonstrated his role: not as a manager or handler, but as a father ensuring his teenage daughter’s safety while respecting her mission.
“Our House is on Fire”: The Family Memoir
In 2020, the Thunberg-Ernman family published “Our House is on Fire: Scenes of a Family and a Planet in Crisis” (originally titled “Scener ur hjärtat” in Swedish). The book, co-authored by all four family members, provides intimate details about their journey.
Svante’s contributions reveal a father’s perspective: the terror of watching his daughter’s depression, the difficult family conversations about lifestyle changes, the confusion and concern as Greta’s activism grew beyond anything they’d imagined. The book became an international bestseller, translated into dozens of languages, though the family has maintained all of Greta’s proceeds go to charity.
Defending Against Conspiracy Theories
Being Greta Thunberg’s father has meant enduring vicious attacks. Climate change deniers and online trolls have spread conspiracy theories claiming Svante and Malena are “puppeteers” controlling Greta, that the family is profiting from her activism, or that they’re part of elaborate globalist schemes.
Svante has patiently, repeatedly debunked these claims. He’s explained in interviews that Greta is “very much her own person,” often more stubborn than her parents. He’s provided transparency about the family’s finances, showing they’ve turned down commercial opportunities. He’s even used humor, once tweeting that if he were really controlling a global movement, he’d probably make it less stressful for everyone involved.
The attacks haven’t been easy. Death threats, harassment, and invasions of privacy have become part of their reality. Yet Svante maintains his focus: protecting his daughters while allowing them to pursue their convictions.
Latest Update: Svante Thunberg in December 2025
As of December 22, 2025, Svante Thunberg continues balancing his roles as father, supporter, and occasional public figure in the climate movement. Recent developments include:
Greta’s University Journey: In 2023, Greta announced she would be stepping back from weekly climate strikes to focus on her studies. Svante and Malena have supported this decision, prioritizing their daughter’s education and personal development over activism. Reports suggest the family has enjoyed more private time together as Greta pursues higher education.
Continued Advocacy: While maintaining a lower profile than during 2018-2020’s peak activism years, Svante still occasionally speaks at events about parenting, climate action, and family transformation. He participated in a November 2025 panel discussion in Stockholm about “Raising Climate-Conscious Children in Uncertain Times.”
Professional Projects: Svante has returned to some creative work in Swedish media, though details remain private. Sources indicate he’s been involved in producing a documentary project related to climate solutions, though official announcements haven’t been made.
Family Life: The Thunberg-Ernman household maintains its climate-conscious lifestyle. Beata, Svante’s younger daughter, now 20 years old, has pursued her own interests in performance and music, largely staying out of the public spotlight by choice. Svante and Malena continue supporting both daughters’ individual paths while maintaining family solidarity.
Recent Interviews: In a December 2025 Swedish radio interview, Svante reflected on the past seven years, noting that while the intensity has decreased, the family’s commitment to climate action remains unchanged. He emphasized feeling hopeful about younger generations’ engagement with environmental issues.
The Philosophy of Supportive Parenting
Throughout his unexpected journey, Svante has articulated a parenting philosophy that resonates with many: listen to your children, take their concerns seriously, and support their agency even when it scares you.
“We didn’t make Greta do this,” he’s explained repeatedly. “We tried to understand what she was going through, and we changed ourselves.” This approach—being willing to be changed by your children’s perspectives—runs counter to traditional top-down parenting models.
Svante also speaks openly about neurodiversity. Both Greta and Beata have been diagnosed with conditions (Asperger’s, ADHD, OCD) that the family views not as disabilities but as different ways of experiencing the world. Svante advocates for embracing these differences rather than trying to “fix” children to fit neurotypical expectations.
Legacy Beyond the Spotlight
While Greta will undoubtedly be remembered as one of the most influential youth activists in history, Svante’s legacy is more subtle but equally important. He represents a model of parental support that prioritizes children’s autonomy, takes their concerns seriously, and is willing to make personal sacrifices for their wellbeing.
In an era of helicopter parenting and social media pressures, Svante and Malena’s approach—making space for their daughter’s unusual path, protecting her welfare while respecting her choices, living their values even when inconvenient—offers an alternative model.
Svante Thunberg didn’t set out to become a public figure in the climate movement. He simply tried to be a good father to a daughter in crisis, listened when she explained what was wrong, and supported her when she decided to act. That this led to his face becoming recognizable worldwide, to sailing across oceans, to co-authoring international bestsellers, and to enduring public scrutiny was never the plan.
