Ilan Goldfajn, president of the Inter-American Development Bank, held a private audience with Pope Francis on Friday to press a case that could reshape parts of Latin America’s economy: responsibly developed rare earths mining. The argument is straightforward — these minerals are critical for modern tech and the energy transition — but the Vatican’s sustained defense of Indigenous communities and ecological protections makes the debate politically sensitive.
Goldfajn’s visit follows earlier outreach by mining executives and comes as global demand for critical minerals intensifies. The IADB executive presented the bank’s plan to finance projects in the region, arguing that with strict oversight, local processing and strong labor and environmental rules, Latin America can capture more value from its resources rather than exporting raw materials.
At stake is both opportunity and risk. Rare earth elements power smartphones, electric vehicles, semiconductors and aerospace components. For governments and investors, they represent a route to growth and industrialization; for local communities, they can mean jobs but also disruption, pollution and contested land rights.

Why the Vatican’s view matters now
Pope Francis’ background in Peru — where he spent decades working in communities affected by extraction industries — gives him particular moral authority across the largely Catholic region. Local dioceses and parish leaders often shape community responses to proposed mines, so the pontiff’s stance influences whether projects meet resistance or cooperation on the ground.
The Holy See has already signaled skepticism about large-scale mining: church networks and Vatican statements have urged dioceses to review investments tied to extractive firms and to strengthen engagement with Indigenous groups. That stance complicates efforts to attract capital for mining projects unless developers can convincingly demonstrate social and environmental safeguards.
What the IADB is proposing
Goldfajn framed the bank’s approach as one focused on standards and downstream value creation rather than simply extracting ore. The IADB says it is managing a pipeline of about $4 billion in projects related to critical minerals, concentrated largely in Chile, Argentina and Brazil, with a significant portion involving private partners and potential European financiers.
His message to the Vatican and to potential investors emphasizes three themes: stronger governance, local processing to keep more revenue in-country, and enforceable environmental and labor protections.
- Governance: clearer permitting, anti-corruption measures and community consultation mechanisms.
- Local value addition: building processing capacity to avoid exporting low-value raw materials.
- Environmental and labor safeguards: strict controls on chemical use, water protection and worker safety.
Environmental and social risks remain central
Processing rare earths can be chemically intensive and, if mismanaged, can contaminate groundwater and soils. That risk, combined with a long regional history of displacement, pollution and unequal benefit-sharing from extractive industries, fuels mistrust among Indigenous and rural populations.
Analysts warn that without third-party monitoring and credible enforcement by national regulators, sustainability promises risk becoming mere rhetoric. For many communities, the memory of past projects that enriched corporations while leaving environmental damage is a powerful reminder to demand concrete protections up front.
How this could affect global supply chains
China currently accounts for more than half of known rare earth oxide reserves, but recent surveys show Brazil among the countries with the largest untapped deposits. Expanding responsible production in Latin America would diversify global supply chains and could reduce geopolitical concentration of these critical inputs.
| Country/Region | Role or potential | Notes |
|---|---|---|
| China | Dominant producer and processor | Holds more than half of global rare earth reserves |
| Brazil | Significant reserves | Identified by USGS as second-largest reserves globally |
| Chile & Argentina | Key IADB project focus | Targets for pilot projects and private-sector partnerships |
For investors and policymakers the calculus is now both economic and ethical: can capital flows be conditioned on measurable social and environmental outcomes that reassure communities and the Church? If the answer is yes, Latin America could capture more industrial benefits from the clean-energy transition; if not, projects may face sustained grassroots resistance and reputational setbacks abroad.
The debate will likely intensify as the pope plans a trip to Peru later this year and as religious networks push for greater transparency in church-linked investments. Meanwhile, the global stock of rare earth oxides is estimated at roughly 75 million tons, with the concentration of reserves and processing capacity shaping who benefits from the next wave of mineral demand.
