Pope Leo XIV will participate in an environmental summit bringing together political leaders, scientists, and activists from around the world, with a common goal: to fight against climate change. Among the guests is Arnold Schwarzenegger, the actor and former governor of California, now an international reference in environmental policies.
The event takes place in Castel Gandolfo, the pontiff’s summer residence, and marks the tenth anniversary of Laudato Si, the historic encyclical by Pope Francis that called for action on the climate crisis. On this occasion, the Church seeks to move from reflection to decisive global action.
Pope Leo, born in the United States and elected after the death of Francis, reiterated that faith must also be expressed through caring for the Earth. With experience in vulnerable communities in Peru, he has witnessed firsthand the devastating effects of floods and extreme weather events exacerbated by climate change.
The conference titled Increasing hope for climate justice will focus on the urgent commitments that must be made before COP30, scheduled in Brazil this November. The meeting aims to build bridges between science, politics, spirituality, and civil society to address a crisis that knows no borders.
Vatican’s Environmental Policies: Faith in Action
Since the publication of Laudato Si in 2015, the Vatican has intensified its environmental policies. Under the guidance of Francis and now Leo XIV, the Catholic Church has promoted a green agenda that goes beyond symbolism.
One of the most concrete measures is the plan to make the Vatican City the first carbon-neutral state. Programs for energy efficiency, installation of solar panels, and a progressive electrification of its vehicle fleet have been implemented.
In parallel, the Church has strengthened partnerships with universities and scientific centers to promote research in clean energy, biodiversity, and food security. These efforts aim not only to reduce the Vatican’s footprint but also to serve as a model for the 200,000 parishes worldwide.
Another key focus has been on influencing international organizations. From the Paris Agreement to the most recent climate summits, the Holy See has positioned itself as a mediator and promoter of consensus. The central idea is that caring for the “common home” cannot be separated from social justice: protecting the poorest also means safeguarding the biodiversity that sustains their livelihoods.
The Power of Communication: Schwarzenegger and the Church
Arnold Schwarzenegger has become an unexpected ally of the Vatican in this crusade. Known for his role as Terminator and his tenure as governor of California, the actor has been promoting projects for pollution reduction and accelerating the transition to renewable energy for years.
During the conference, he emphasized that the world’s 1.4 billion Catholics represent a unique force to change habits and demand sustainable policies. For him, faith can be a powerful tool to mobilize entire communities in defense of the planet.
His participation alongside indigenous leaders, environment ministers, and bishops reinforces the global and inclusive nature of the event. The combination of religious, scientific, and cultural voices aims to send a clear message: the climate crisis requires collaboration and commitment beyond ideologies or creeds.
Towards a New Environmental Pact
Pope Leo XIV’s challenge is to turn awareness into action. Reducing emissions by almost half by 2030, as indicated by the Paris Agreement, requires drastic decisions in energy use and the economic model.
The Church proposes that the change be addressed not only as an environmental problem but as a matter of justice. The most vulnerable are the ones who suffer first from droughts, floods, and forced migrations. Therefore, caring for creation is also caring for human dignity.
The union of the Vatican with global actors like Schwarzenegger symbolizes a new chapter in the climate fight: science, politics, and spirituality in dialogue for the planet’s survival. The final message is clear: hope exists, but only if it translates into immediate collective actions.
