Marking 40 years since the Chernobyl disaster, Pope Leo XIV calls for ethical and responsible use of atomic energy, warning of technological risks and urging global accountability.
Newsroom (27/04/2026 Gaudium Press ) On the 40th anniversary of the Chernobyl nuclear disaster, Pope Leo XIV called for greater responsibility in the use of atomic energy, emphasizing the enduring lessons of one of history’s most catastrophic technological failures.
The April 1986 explosion at the Soviet-era Chernobyl nuclear power plant in Ukraine killed more than two dozen people in its immediate aftermath. In the decades since, thousands have suffered severe health consequences linked to prolonged radiation exposure. The disaster remains widely regarded as the worst nuclear accident in history and is one of only two events—alongside Japan’s 2011 Fukushima disaster—to reach the highest severity level on the International Atomic Energy Agency’s INES scale.
The handling of the crisis by Soviet authorities has faced sustained criticism over the years, particularly regarding delayed disclosure and inadequate protective measures for affected populations.
“Today marks the 40th anniversary of the tragic incident in Chernobyl,” Pope Leo XIV said in remarks delivered Sunday. He described the disaster as an event that “left a lasting mark on the conscience of humanity,” underscoring its continuing moral and technological implications.
The pontiff warned that Chernobyl stands as a stark reminder of “the inherent risks of using increasingly powerful technologies.” He urged global leaders and decision-makers to prioritize ethical judgment, adding, “May discernment and responsibility always prevail at every level of decision-making so that all use of atomic energy may be placed at the service of life and peace.”
Leo XIV also offered prayers for those who lost their lives and for individuals still suffering from the long-term effects of the disaster, entrusting them to “God’s mercy.”
Since the beginning of his pontificate, Leo XIV has consistently highlighted the broader impact of technological advancement on human society. His choice of papal name reflects an intentional connection to Pope Leo XIII, whose 1891 encyclical Rerum novarum addressed the social upheavals of the industrial revolution.
In a May 10, 2025 address to cardinals shortly after his election, Leo XIV drew parallels between that era and today’s rapid technological transformation. He described the modern age as another kind of industrial revolution, pointing specifically to developments in artificial intelligence as posing “new challenges for the defense of human dignity, justice and labor.”
His remarks on Chernobyl align with this broader concern, framing nuclear energy—and technology more broadly—not only as tools of progress but as forces that demand careful ethical stewardship.
