Have you ever wondered what "sustainable" really means when it comes to massive sporting events? And more importantly—who gets to define it?
Welcome to FreeAstroScience, where we break down complex topics into digestible pieces. Today, we're tackling a big question that deserves honest answers. The Milan-Cortina 2026 Winter Olympics are knocking on our door. They've been marketed as the most environmentally friendly Games in history. But here's the thing: promises are easy. Data is harder. And missing data? That's where the real story hides.
Grab a coffee. Let's dig into what the numbers say—and what they don't.
What the Organizers Are Claiming
Let's give credit where it's due. The Milan-Cortina 2026 Foundation has made some noteworthy commitments. On paper, they look impressive.
Here's what they're promising - greenMe.pdf):
- 100% renewable electricity from certified sources
- First-ever water footprint monitoring for a Winter Olympics
- 85% of venues already exist—reducing new construction
- 47% female athletes—a record for Winter Games gender balance
These aren't small achievements. Using existing infrastructure is a big deal. Previous Winter Olympics have left behind ghost towns of unused facilities. Remember Sochi? Those abandoned stadiums still haunt Russia's budget.
The gender balance matters too. It signals progress in a sports world that's historically favored men.
But here's where we need to pump the brakes.
The Data That's Missing (And Why It Matters)
When we talk about real sustainability, the problem isn't just what the data tells us. It's what the data doesn't tell us.
A coalition of 20 national and regional organizations launched the "Open Olympics 2026" campaign in May 2024. This group includes heavy hitters like WWF Italia, Legambiente, the Italian Alpine Club, and Italia Nostra. They're asking tough questions. And they're not getting answers.
Here's what's concerning: the official Open Milano Cortina 2026 portal lists 98 infrastructure projects. Sounds comprehensive, right? Wrong.
| Source | Projects Listed | Estimated Cost | Missing from Official Portal |
|---|---|---|---|
| Open Milano Cortina 2026 Portal | 98 | Not fully disclosed | — |
| Lombardy Region ("Oltre i Giochi 2026") | 78 | €5.17 billion | 44 projects (€3.82 billion) |
Let that sink in. €3.82 billion in projects aren't even listed on the main transparency portal. That's not a rounding error. That's a canyon-sized gap in public information.
The Carbon Footprint Question
Here's the number everyone should know: 1,005,000 tons of CO₂ equivalent.
That's the estimated carbon footprint for the entire Games lifecycle, according to the Milan-Cortina 2026 Foundation . To put that in perspective:
Imagine every single resident of Milan—all 1.4 million of them—hopping on a plane for a round-trip flight from Rome to New York. That's roughly the carbon cost we're talking about.
Sounds massive? It is.
But here's the catch: we can't verify where those emissions come from. There's no breakdown by individual infrastructure project. No transparency about which venues carry the heaviest environmental load.
Why does this matter? Because if we don't know which projects emit the most, we can't:
- Prioritize greener alternatives
- Hold specific contractors accountable
- Learn lessons for future events
It's like saying "I spent €1,000 this month" without knowing if it went to groceries, gambling, or charity. The total number means nothing without context.
Following the Money Trail
Money talks. But in this case, it's whispering—and we can barely hear it.
The original government decrees specified funding sources. Who was paying for what? It was all laid out. But on the current portal? That information has vanished. - greenMe.pdf)
We know the costs. We don't know who's covering the overruns.
And those overruns are significant. Take the Paralympics budget:
| Budget Category | Amount |
|---|---|
| Original estimate | €71.5 million |
| Current allocation (Commissioner) | €328 million |
| Increase | +359% |
A 359% budget increase. That's not budget creep. That's a budget avalanche.
And what about subcontractors? Their names appear on the portal. But their contract values don't. Neither do the CIG codes (Italy's unique contract identifiers). Without those codes, we can't cross-reference with ANAC—the national anti-corruption authority.
Translation: we see the players, but we can't see how much they're getting paid.
Three Civic Questions Still Without Answers
The Open Olympics 2026 coalition has identified three questions that remain "frighteningly open" - greenMe.pdf):
1. What's the Real Cost?
The Foundation's "Budget Lifetime" reportedly sits at €1.7 billion as of 2025. One problem: the document isn't public . The Foundation operates as a private entity. This is legally fine. But it severely limits public access to information.
2. Who's Paying for Safety and Health?
The Sports Decree allocates €271 million for security. Here's the uncomfortable part: €43 million of that comes from the Fund for Mafia and Usury Victims.
Read that again. Money meant for crime victims is being redirected to Olympic security.
On the health side, there's no unified plan. Each region handles it independently. No one knows the total healthcare cost.
3. What's the Paralympics Commissioner Actually Doing?
This commissioner controls €328 million to spend between September and December 2025. That's a lot of money in a short window. The first quarterly report was due by December 5th. It hasn't been published yet.
Who's Watching the Watchmen?
Here's the silver lining in this cloudy story.
Twenty organizations are refusing to look away. They include - greenMe.pdf):
- Libera (anti-mafia association)
- WWF Italia
- Legambiente
- Club Alpino Italiano
- Italia Nostra
- Mountain Wilderness Italia
- CIPRA Italia
These groups have adopted a simple but radical principle: "Don't move a stone without transparency." - greenMe.pdf)
They're already collaborating with French civil society ahead of the 2030 Winter Games. The goal? Make transparency non-negotiable for all future Olympic events.
This matters because citizens deserve to know. When public money builds public infrastructure for public events, the public should see the receipts.
What This Means for You
You might be wondering: "I'm not Italian. Why should I care?"
Fair question. Here's the answer.
Every major sporting event sets precedents. The standards we accept today become the baseline for tomorrow. If we let "most sustainable ever" become a marketing slogan instead of a measurable commitment, we lose something important.
We lose accountability.
What can you do?
- Ask questions. When you hear "green" or "sustainable," ask for the numbers.
- Support watchdog organizations. They're doing the heavy lifting.
- Stay informed. The sleep of reason breeds monsters. Don't let your mind go to sleep.
Conclusion: When Green Claims Need Greener Proof
Milan-Cortina 2026 might indeed be more sustainable than previous Winter Olympics. The renewable energy commitment is real. The use of existing venues is a genuine step forward. The gender balance is historic.
But "better than before" isn't the same as "good enough."
When €3.82 billion in projects aren't listed on transparency portals, when carbon footprints lack breakdowns, when budget increases hit 359% without explanation—we're not looking at the full picture.
Sustainability isn't just about solar panels and recycled materials. It's about transparency, accountability, and truth. Without those, every green claim floats in a fog of uncertainty.
The Olympics carry weight. They shape how cities develop. They influence how billions of people think about sports, infrastructure, and yes—sustainability. Getting this right matters.
So let's keep asking questions. Let's demand data. Let's refuse to accept press releases as proof.
