Proton Sustainability: Proton Mail, Drive, and more

When people talk about Proton, the conversation usually starts with privacy. Proton Mail, Proton Drive, Proton VPN — all built with strong encryption and user control at their core. But there’s another part of Proton’s mission that deserves just as much attention: sustainability. Currently, their data centers seem to run on 100% green energy.

Contact with their Customer Support

Little is found on Proton’s website. That’s why I decided to contact Proton’s Customer Support. They sent me:

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.

Sustainability as a Core Value

Proton has made it clear that environmental responsibility matters just as much as protecting user data. Their approach to sustainability isn’t an afterthought or a marketing checkbox; it’s embedded into how their infrastructure is built and maintained.

According to Proton, they consistently aim to choose the most eco-friendly energy options available. This means prioritizing renewable energy sources wherever possible and working with partners who share those values.

100% Green Energy Data Centers

One of the most significant commitments Proton has made is powering its data centers entirely with green energy. Today, all Proton data centers run on 100% renewable energy, with a large portion coming from hydroelectric power.

Hydroelectric energy is one of the most stable and low-emission renewable sources available, making it a strong choice for always-on services like secure email and cloud storage. For users, this means that sending an encrypted email or storing files in Proton Drive doesn’t come with the same environmental cost as many traditional cloud services.

Choosing Sustainable Partners

When Proton selects data center suppliers, sustainability is a key factor in the decision. If there’s an option to work with providers who value renewable energy and responsible operations, Proton chooses it.

This partner-driven approach matters. Even the most privacy-focused software still relies on physical infrastructure, and Proton’s willingness to prioritize green suppliers helps reduce the broader environmental impact of its services.

Transparency — With Security in Mind

Proton is open about its sustainability goals and energy usage, but there are limits to what can be publicly shared. Some infrastructure details can’t be disclosed for security reasons — a necessary trade-off when running privacy-critical services.

What is clear, though, is the direction: renewable energy, responsible suppliers, and continuous improvement.

Why This Matters

Digital privacy and environmental sustainability are often treated as separate issues, but they’re deeply connected. A secure internet that harms the planet isn’t a long-term solution — and Proton seems to understand that.

By running Proton Mail, Proton Drive, and other services on green energy, Proton shows that privacy-first technology doesn’t have to come at the planet’s expense.

The Bigger Picture

Sustainability is an ongoing process, not a final destination. Proton openly acknowledges that it’s an area they continue to focus on and improve over time. As technology evolves and greener options become available, that commitment becomes even more important.

For users who care about both privacy and the environment, Proton’s approach offers something rare: peace of mind on multiple levels.

Privacy protects your future. Sustainability protects everyone’s. Proton is working toward both.
