Pope Leo XIV is calling for a fundamental shift in lifestyle, one rooted in respect for creation, as he addressed participants at the XVII International Forum of the environmental organization Greenaccord in Treviso, Italy. The message, delivered via a telegram signed by Cardinal Secretary of State Pietro Parolin, comes as the world grapples with increasingly urgent environmental challenges and underscores the Vatican’s ongoing commitment to ecological concerns. The Pope’s appeal extends beyond scientific data and technological solutions, emphasizing the demand for a deeply ingrained ethical and communal approach to safeguarding the planet for future generations.
The call for a new way of life isn’t simply about adopting “green” technologies, but about a transformation of values, according to the Vatican. This message arrives as discussions around climate change, biodiversity loss, and resource depletion intensify globally. The forum in Treviso, themed “Building Future Together,” provides a platform for dialogue between environmental experts, religious leaders, and policymakers. The Pope’s intervention highlights the critical role of faith-based organizations in advocating for environmental stewardship and promoting sustainable practices. The Vatican has been a vocal advocate for climate action, most notably through the 2015 encyclical Laudato Si’, which called for “integral ecology” – a holistic approach that considers the interconnectedness of environmental and social issues.
Central to Pope Leo XIV’s message is the idea that preserving creation requires “spirit, heart, and hands” working in unison. This echoes the teachings of St. Francis of Assisi, whose “Canticle of the Creatures” – commemorating its 800th anniversary this year – was a focal point of the forum. Cardinal Parolin, in his address, described the legacy of St. Francis as a form of “diplomacy of cultures,” urging attendees to move beyond viewing environmental protection as a mere ideology or a “heartless administration.” The Pope’s emphasis on a holistic approach suggests a rejection of purely technical fixes, arguing that lasting solutions require a fundamental shift in human attitudes, and behaviors.
Beyond Data: The Need for Ethical Frameworks
Pope Leo XIV’s recent Apostolic Letter, Disegnare nuove mappe di speranza (“Drawing New Maps of Hope”), released in October 2025, provides further context for his remarks. The letter stresses that while technical data is essential, it is insufficient on its own. The Pope advocates for cultivating “virtuous community practices” and fostering new habits that will guarantee an inclusive and respectful social environment for future generations. This emphasis on ethical considerations is particularly relevant in the context of rapidly advancing technologies, such as artificial intelligence.
Artificial Intelligence and the “Integral Intelligence”
Cardinal Parolin specifically linked the Franciscan spirit to the challenges posed by artificial intelligence (AI). He argued that AI serves as a “test of humanity’s anthropological maturity.” The Vatican is calling for an “integral intelligence” – one that embeds ethical guidelines into the very design and governance of AI systems, ensuring transparency and accountability. This isn’t simply about preventing misuse, but about proactively shaping AI development to align with human values and promote the common good. The concern reflects a broader global debate about the ethical implications of AI, including issues of bias, privacy, and job displacement.
The Interconnectedness of Ecology and Social Justice
A core tenet of the Vatican’s environmental message, reiterated in Treviso, is the inseparable link between ecology and social justice. Where the creation is harmed, society suffers, and where human dignity is diminished, nature is reduced to a mere resource. This perspective aligns with the concept of “ecological debt,” which argues that wealthier nations have a moral obligation to address the environmental damage caused by their historical and ongoing consumption patterns. The Vatican’s stance underscores the importance of addressing systemic inequalities as part of any comprehensive environmental strategy.
The forum in Treviso as well highlighted the growing calls for a transition to renewable energy sources, particularly from the Global South. Vatican News reported that church representatives from five continents are urging a rapid phase-out of fossil fuels, emphasizing the disproportionate impact of climate change on vulnerable communities. This call for energy justice reflects a growing recognition that climate solutions must be equitable and inclusive.
Cardinal Parolin concluded by advocating for “custodia” – protection – in all its facets: protecting our neighbor, safeguarding science as wisdom, and viewing technology as a tool, not an complete in itself. “Building the future together” must not remain a purely operational-technical goal, he argued, but become a “style of soul and institutions” – a diplomacy of peace that finds its ultimate proof in protecting the most vulnerable. The Vatican’s continued engagement on environmental issues signals a long-term commitment to fostering a more sustainable and just world.
The Vatican is expected to release further details on its environmental initiatives in the coming months, including potential collaborations with international organizations and governments. The next major event on the Vatican’s calendar related to environmental stewardship is a planned symposium on sustainable finance in November 2026.
