Vatican commits $117 million to build agrivoltaic plant for carbon neutrality
The Holy See will invest roughly 100 million euros in an agrivoltaic solar farm on its Santa Maria di Galeria estate, aiming to become the first carbon-neutral sovereign state within two years.
The Vatican announced a budget of roughly 100 million euros to build an agrivoltaic solar plant on its Santa Maria di Galeria estate, a site comparable in size to large AI data-center campuses. Pope Leo has advanced the plan since Pope Francis’s 2024 climate letter, creating a foundation, a memorandum with Italian utility ACEA, and a joint commission to move the project forward. Expected to generate 80-90 megawatts, the farm will dwarf the Vatican’s current 2,394-panel rooftop system and help the microstate achieve carbon-neutral status within two years.
The effort underscores the Holy See’s long-standing moral stance on climate change, contrasting with the massive electricity consumption of AI data centers that are reshaping U.S. utility markets. While the Vatican’s footprint is tiny—about 109 acres and home to 800 residents—the new plant will supply enough power for its community and a radio transmitter. The development also highlights the Vatican’s broader pledge to cut emissions 20% by 2030 and reach zero emissions by 2050.
Why it matters
It shows a sovereign state committing substantial funds to renewable energy, highlighting climate action beyond large economies.
