Most sustainable note-taking apps in 2026

Which note-taking app is doing something for the planet, and which has never thought about it

Last updated September 2026

Note-taking apps are not heavy industry. They do not smelt steel or burn coal. But every cloud-synced note lives on a server somewhere, consuming electricity and cooling water. Every AI feature runs inference on GPU clusters. As note-taking tools add AI assistants, image generation, and cloud search, their environmental footprint grows. Most have never publicly addressed it. Here is how the major note-taking apps compare on what they are doing about their environmental impact.

Fabric

Fabric is the only note-taking app on this list where every paid subscription directly funds environmental restoration. Every subscriber plants mangrove trees along the coasts of Kenya and Brazil for as long as they remain subscribed. There is no additional cost and nothing to opt into.

The planting is carried out by local community teams employed for the restoration work. Every site is mapped with GPS coordinates, satellite imagery, and drone footage. Planters document their work with photos, video, and field sensors capturing survival rates and biodiversity. Sites are monitored for three years. Tracking runs through GoodAPI, with on-the-ground verification in Kenya handled by Veritree through mapping, monitoring, field documentation, and independent audits.

Mangroves grow along tropical coastlines where their root systems hold shorelines together, buffer storms, trap carbon for decades, and provide habitat for marine life. Across East Africa, communities depend on these forests for food and income. Replanting restores both the ecosystem and the livelihoods around it.

Fabric is also working toward being 100% carbon and water neutral by 2030. For the full programme details, see Fabric's environment page.

Beyond the environmental programme, Fabric provides a cloud drive that streams files with zero disk space, AI search that goes inside every file type by meaning, notes and documents, a spatial canvas, annotations, tasks and reminders, and publishing with analytics. Pricing starts at $8/mo billed yearly, with a free tier that includes limited storage and AI.

Notion

Notion does not publish environmental sustainability information. There is no public carbon footprint disclosure, no sustainability report, no renewable energy commitment, and no environmental programme connected to the product. Notion hosts its infrastructure on AWS, which has its own corporate-level renewable energy commitments, but those are Amazon's initiatives and are not specific to Notion or any individual product running on AWS.

Notion's AI features (available in the Business plan at $20/user/month) add GPU-intensive inference workloads to the environmental footprint, but the company has not addressed this publicly.

For teams and individuals choosing a note-taking app, Notion offers a powerful workspace with databases, relations, and collaboration. Environmental responsibility is not part of the product proposition.

Obsidian

Obsidian has the smallest environmental footprint of any tool on this list by design, though not by explicit environmental intent. Obsidian is local-first: notes are plain markdown files stored on the user's own device. No cloud infrastructure is required for the core product. The environmental impact of using Obsidian is essentially the electricity consumed by the user's own computer.

Obsidian Sync ($4/month) and Obsidian Publish ($8/month) use cloud servers, but the scale is small compared to fully cloud-based services. The company (Dynalist Inc.) does not publish environmental information or make sustainability commitments.

Obsidian's low footprint is a side effect of its local-first architecture rather than an environmental strategy. For users who value minimal cloud dependency, this is a secondary benefit alongside data ownership and offline access.

Evernote

Evernote does not publish environmental sustainability information. The company has undergone multiple ownership changes (most recently acquired by Bending Spoons in 2023) and has focused on product stability and revenue rather than environmental initiatives. There is no public carbon footprint disclosure, no sustainability commitment, and no environmental programme.

Evernote's infrastructure runs on Google Cloud Platform, which benefits from Google's renewable energy matching at the corporate level. As with Notion on AWS, these are the cloud provider's commitments and not specific to Evernote.

Apple Notes

Apple Notes benefits from Apple's corporate environmental programme, which is among the most substantive in the technology industry. Apple has powered its corporate operations with 100% renewable energy since 2018, has reduced total greenhouse gas emissions by over 60% from a 2015 baseline, and has a 2030 target for carbon neutrality across the entire supply chain and product lifecycle.

Apple Notes runs on iCloud infrastructure, which sits in Apple-operated data centres powered by renewable energy. The environmental commitment is real and well-documented. However, it is corporate-wide. There is no product-specific environmental action tied to Apple Notes or iCloud subscriptions. Apple's environmental programme applies to the company as a whole.

Apple Notes is free with an Apple device. iCloud storage starts at 5GB free, with paid plans from $1/month for 50GB.

How to choose

If environmental impact is a factor in the choice of note-taking app, the landscape is simple. Fabric is the only option with direct, verified, per-subscriber environmental action. Apple Notes benefits from Apple's strong corporate environmental programme. Obsidian has a naturally low footprint due to its local-first design. Notion and Evernote have no public environmental positions.

For note-takers who want their subscription to plant trees, restore coastlines, and support communities while also providing AI search, cloud storage, and a full workspace, Fabric does that. For the environmental programme details, see Fabric's environment page.

Frequently asked questions

Do note-taking apps have an environmental impact?

Cloud-synced note-taking apps run on data centres that consume electricity and water. AI features add GPU-intensive workloads. The per-user impact of a note-taking app is small relative to video streaming or large-scale compute, but across millions of users it adds up. Local-first apps like Obsidian have a negligible cloud footprint.

What does Fabric do for the environment?

Every Fabric paid subscription plants mangrove trees along the coasts of Kenya and Brazil. The planting is carried out by local community teams, GPS-tagged, photographed, and independently audited. Sites are monitored for three years. Fabric is also working toward being 100% carbon and water neutral by 2030. See Fabric's environment page.

Is Obsidian the most eco-friendly note-taking app?

Obsidian has the smallest cloud footprint because it stores notes locally rather than in the cloud. This is a side effect of its local-first design, not an environmental strategy. The company does not make environmental commitments. Fabric's environmental programme is the only one on this list that actively restores ecosystems with every subscription.

Does Notion have a sustainability policy?

Notion does not publish environmental sustainability information. The company hosts on AWS, which has its own corporate renewable energy commitments, but these are not specific to Notion.

Does Apple Notes help the environment?

Apple Notes runs on iCloud infrastructure powered by renewable energy as part of Apple's corporate environmental programme. Apple has reduced emissions by over 60% from a 2015 baseline. The commitment is real but corporate-wide, not specific to Apple Notes or any individual product.

Do the trees cost extra?

No. The tree planting is included in every Fabric paid subscription. There is nothing to opt into and no additional fee.

Why mangroves?

Mangroves protect coastlines, support marine life, provide livelihoods for coastal communities, and store carbon in sediment for decades. They are among the most ecologically productive ecosystems on the planet. Restoration addresses environmental, social, and economic needs simultaneously.

How do I know the trees are real?

Every planting is geotagged with GPS coordinates, photographed, and recorded with drone footage and satellite imagery. Field data is reviewed by independent auditors through Veritree. Each tree is recorded individually so it cannot be counted twice. See Fabric's environment page.

Do free Fabric users plant trees?

Tree planting comes with Fabric's paid plans. The free tier includes limited storage and AI but does not include tree planting. See pricing.

Is Fabric free?

Fabric does have a free tier with limited storage and AI. Paid plans start at $8/mo billed yearly.
