Most discussions about Proton revolve around privacy — and for good reason. Proton Mail, Proton Drive, and Proton VPN are all built around strong encryption and user autonomy. But there’s a side of Proton that doesn’t get nearly enough attention: its commitment to environmental sustainability. As it turns out, all of Proton’s data centers currently run on 100% green energy.
What Proton’s Own Support Team Had to Say
Details about Proton’s environmental practices are hard to find on their website, so I reached out directly to their customer support team. Here’s what they shared:
Thank you for reaching out. Kindly note that we care about the environment as much as we care about privacy. We look to always choose the most eco-friendly option for our energy needs. Proton uses renewable energy, mostly from hydroelectric sources. Sustainability is important to us and an area that we continually focus on. When the option is available, we use data center suppliers who also value sustainability. Currently, all our data centers run on 100% green energy. Unfortunately, we cannot disclose more information for security reasons.
It’s a short but telling response. Proton isn’t just paying lip service to sustainability — it’s baked into how they choose infrastructure and partners.
Green Energy Powering Every Data Center
Perhaps the most striking detail in that response is that every single Proton data center runs on 100% renewable energy. A significant portion of that comes from hydroelectric power, which is among the most reliable and lowest-emission energy sources available.
That matters more than it might seem. Services like encrypted email and cloud storage require servers that are always on. Traditionally, that kind of constant uptime comes with a real environmental cost. With Proton, storing files in Proton Drive or sending a secure message through Proton Mail doesn’t carry the same carbon footprint as it would with many conventional cloud providers.

Sustainability Isn’t an Afterthought — It Shapes Who They Partner With
What stands out about Proton’s approach is that sustainability influences decisions at the infrastructure level. When evaluating data center suppliers, Proton actively prioritizes partners who share their commitment to responsible energy use. If a greener option exists, they take it.
This is worth highlighting because even the best privacy software still depends on physical hardware running in real buildings consuming real power. A company’s environmental impact isn’t just about its own operations — it extends to every supplier in the chain. Proton seems to take that seriously.

Privacy and the Planet: Two Goals, One Mission
It’s easy to treat digital privacy and environmental responsibility as unrelated concerns, but they’re more connected than most people realize. Building a secure internet on top of carbon-heavy infrastructure is a short-sighted trade-off. Proton appears to understand that a truly responsible tech company has to think beyond the data it protects.
By powering its services with renewable energy and choosing sustainable partners, Proton demonstrates that privacy-first technology and environmental care can go hand in hand. You don’t have to choose between protecting your data and reducing your footprint.

A Note on Transparency
Proton is candid about what they can and can’t share. While they’re open about their sustainability goals and energy sources, specific infrastructure details are kept private for security reasons. That’s a reasonable trade-off for a company whose entire value proposition is built on protecting sensitive information.
What’s important is the overall direction: 100% renewable energy, environmentally responsible partners, and a stated commitment to continuous improvement as better options become available.
The Bottom Line
For users who care about both privacy and the environment, Proton offers something that’s genuinely rare in the tech industry: a service that takes both seriously. Running entirely on green energy while delivering end-to-end encrypted communications is no small feat.
Sustainability is an ongoing journey, and Proton acknowledges that openly. But the foundation is solid. If you want to save on Proton’s services while supporting that mission, take a look at our Proton Unlimited discount guide or browse the latest Proton deals and coupons.
Protecting your privacy and the planet at the same time — that’s a combination worth getting behind.
