Every search you make is a vote. For the climate, for data independence, and for who controls Europe's digital future. Digital infrastructure eats up to 9% of global electricity. Over 80% of the software Europe runs on is American-made. These two facts are deeply connected, and most of us never think about either when we hit "search." Data centres consumed 415 TWh in 2024. That's 40 nuclear power plants' worth. By 2030? It doubles. But here's the thing. It doesn't have to be someone else's problem. Platforms like Ecosia are proving that a search engine can plant 230 million trees, run on 200% renewable energy, AND build an independent European search index. All at once. Digital policy is climate policy. Your next search is a choice. Make it count.

Digital Independence and Climate Justice: An Emerging Connection

Every time you type a search query, you are making a small but measurable choice: where that data goes, who processes it, and what energy powers it. Multiplied across hundreds of millions of searches each day, those choices add up to something significant — both for the climate and for Europe’s geopolitical independence. Digital infrastructure currently accounts for up to 9% of global electricity consumption, and over 80% of the software and cloud services used in Europe are provided by US companies. These two facts are deeply connected: whoever controls the servers controls the energy standards, the data, and ultimately the pace of the green transition. Understanding that link is the starting point of this article.

What Is ICT Sovereignty?

ICT (Information and Communication Technology) sovereignty represents Europe's efforts to establish greater control over its digital infrastructure—from search engines to cloud storage to AI systems—rather than relying predominantly on foreign technology providers.

Over 80% of technologies used in Europe are imported, mainly from the USA, which creates strategic vulnerabilities. This dependency raises concerns about data security, economic resilience, and regulatory autonomy. The connection to climate policy becomes apparent when we consider that control over digital infrastructure means control over environmental standards and energy sourcing decisions.

The Digital Carbon Footprint

Digital technologies currently account for an estimated 5–9% of global electricity consumption and 2–4% of global greenhouse gas (GHG) emissions. These figures are rising rapidly: global data centres alone consumed 415 TWh of electricity in 2024 according to the IEA — roughly the annual output of 40 nuclear power plants — and electricity demand in AI-focused data centres is projected to grow by around 30% per year. While these percentages may appear modest today, the absolute numbers are significant and accelerating as AI and high-performance computing expand.

For every search query or data transfer, energy is consumed in massive data centers and across networking equipment. Achieving "Net Zero" requires not just cleaner energy for homes and transport, but a fundamental rethink of our digital architecture.

The "Twin Transition" Framework

The European Union has identified the "Twin Transition"—the simultaneous green and digital transformation—as its core strategy for the 2020s. The goal is to ensure that digital technology becomes an enabler for sustainability rather than a burden.

Key legislative pillars include:

  • The Data Act (entered into force January 2024; applicable from September 2025): Establishing rules on who can use and access data generated in the EU.
  • The Digital Fairness Act (legislative proposal expected Q4 2026): Targeting "dark patterns" and ensuring consumers have transparent choices.
  • The Cyber Resilience Act: Setting mandatory security requirements for hardware and software.

Case Study: Ecosia—A Model for Sustainable Digital Services

Ecosia serves as a practical example of how ICT sovereignty and sustainability intersect.

The Ecosia Model

Ecosia is a search engine that uses its profits to plant trees and restore ecosystems. As of early 2026, it has transitioned toward greater independence by launching its own search index, Staan, in collaboration with the French search engine Qwant. This move reduces reliance on external providers like Microsoft Bing and Google.

Relevance to Digital Sovereignty

By building its own index, Ecosia ensures that search results are not entirely dependent on foreign algorithms. This contributes to a more diverse European digital ecosystem, which is a key goal of the "EuroStack" initiative.

Demonstrated Results

The numbers behind Ecosia demonstrate that combining digital sovereignty with climate action is not just theory. By 2025, Ecosia had funded the planting of over 230 million trees across 35 countries — achieving its original target ahead of schedule. Its solar plants produce more than twice the renewable energy needed to power all searches on the platform. In May 2025, Ecosia introduced real-time climate impact tracking, allowing users to see exactly how their searches fund specific reforestation projects around the world. Crucially, by building its own independent European index (Staan), Ecosia is also reducing its reliance on US tech infrastructure — demonstrating that digital sovereignty and environmental responsibility are two sides of the same coin. If a European search engine can reduce dependence on foreign data pipelines while channelling profits into climate action, it offers a concrete model for what a sovereign, sustainable digital ecosystem could look like at scale.

The EU's Strategic Approach: EuroStack and Policy Integration

The "EuroStack" is a conceptual framework for a sovereign European digital layer. It aims to integrate European values—privacy, transparency, and sustainability—into the very fabric of our software and hardware.

By prioritizing energy-efficient data centers located within the EU, "EuroStack" ensures that European green standards are applied to the data that powers our economy. This reduces the "carbon leakage" that occurs when European data is processed in regions with lower environmental regulations.

Hungary’s Approach: National Priorities and Dual Objectives

Hungary has taken a distinct approach to these issues, focusing on how digital sovereignty can protect national narratives and support local environmental goals.

Climate Progress and Energy Security

Hungary’s "Water into the Landscape" programme, launched in February 2025, uses digital monitoring to restore local water cycles. By maintaining control over the data generated by these environmental sensors, Hungary ensures that its climate adaptation strategy remains independent of foreign data silos.

Sovereignty as National Narrative Protection

In the Hungarian context, ICT sovereignty is often viewed through the lens of "narrative protection"—ensuring that digital platforms operating within the country respect local cultural and political nuances.

Strategic Implications: Connecting the Dots

The lesson for 2026 is clear: digital policy is climate policy.

  1. Supply Chain Resilience: Reducing dependency on foreign ICT providers mitigates the risk of supply chain disruptions that could stall green energy transitions.
  2. Regulatory Autonomy: Sovereign infrastructure allows the EU to enforce strict energy-efficiency standards (like those in the Ecodesign for Sustainable Products Regulation) across the entire tech stack.

Conclusion

The choice of a search engine or a cloud provider is no longer just a matter of user experience; it is a political and environmental act. When European consumers choose platforms like Ecosia, they are not simply planting trees — they are redirecting data flows, funding independent European infrastructure, and signalling to policymakers that sovereignty and sustainability are priorities worth acting on. The stakes are growing. Global data centre electricity consumption is set to more than double to around 945 TWh by 2030 — roughly Japan’s entire electricity consumption today — and the majority of that growth will be shaped by whoever controls the underlying digital infrastructure. Europe has both the regulatory tools — from the Data Act to the EuroStack initiative — and the consumer base to steer this transition. What is needed now is the collective will to use them. Digital policy is climate policy. Every search, every platform choice, and every piece of legislation that supports a sovereign, energy-accountable digital sector moves Europe closer to a future where independence and ecological responsibility reinforce each other rather than compete.
