Most sustainable cloud storage in 2026
Which cloud storage provider is doing something concrete for the environment, and which is coasting on corporate pledges
Log in
Last updated September 2026
Cloud storage runs on data centres, and data centres run on electricity and water. Every file synced, every backup uploaded, every photo streamed from the cloud has a physical cost measured in watts and litres. As people and businesses move more of their lives into cloud storage, the environmental footprint of these services grows. Some providers have made commitments. Fewer have followed through. Even fewer tie environmental action to the product itself.
Here is how the major cloud storage providers compare on what they are concretely doing about their environmental impact.

Fabric
Fabric is the only cloud storage provider 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 nothing extra to sign up for and no additional cost.
The planting is carried out by local community teams who are employed to do 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 to ensure the forests survive and are not cleared. Tracking and reporting 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, soften the impact of storms, trap carbon in sediment for decades, and provide breeding habitat for marine life. Across East Africa, communities depend on mangrove forests for food, work, 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.
The cloud drive streams files using zero disk space from any device. AI search goes inside every file type by meaning. The workspace includes notes and documents, a spatial canvas, annotations, and publishing with analytics. Pricing starts at $8/mo billed yearly, with a free tier that includes limited storage and AI.
Google Drive
Google has invested more in corporate sustainability than any other company on this list. The company has matched 100% of its electricity consumption with renewable energy purchases every year since 2017. Annual Environmental Reports provide detailed data on emissions, energy, water, and waste. Google's net-zero by 2030 target is backed by investments in clean energy, water stewardship, and circular economy initiatives.
The challenge is that AI-driven data centre expansion has pushed total emissions in the opposite direction. Google's greenhouse gas emissions rose approximately 50% between 2019 and 2024. The company's 2025 Environmental Report showed improved data centre energy efficiency but acknowledged that growth outpaced efficiency gains in aggregate. Supply chain emissions (Scope 3) continue to climb.
Google Drive benefits from this corporate infrastructure. Files stored in Google Drive sit in data centres powered by matched renewable energy purchases. But the environmental commitment is corporate-wide. There is no mechanism by which a Google Drive subscription specifically funds environmental action. The renewables exist whether or not any individual uses Drive.
Google Drive provides 15GB free with a Google account. Google One plans extend storage from 100GB at $2/month to 2TB at $10/month.
Dropbox
Dropbox reached 100% renewable energy for its data centre operations in 2021 and has maintained that commitment since. The company published an inaugural ESG Impact Report and has shared details on its data centre sustainability strategy, including custom-designed infrastructure for energy efficiency.
Dropbox set a target for carbon neutrality by 2030. The company is smaller than Google, Apple, or Microsoft, which means its total environmental footprint is proportionally smaller, but it also means sustainability efforts receive less investment and public attention.
Like the others, Dropbox's environmental commitments are at the corporate level. There is no product-level environmental action. Using Dropbox does not fund tree planting, carbon removal, or restoration projects. The renewable energy commitment applies to the infrastructure regardless of how many people use the service.
Dropbox Plus provides 2TB at $11.99/month. Business plans start at $18/user/month.
iCloud (Apple)
Apple's environmental programme is among the most ambitious in the technology industry. The company has powered its corporate operations with 100% renewable energy since 2018. Apple's 2030 target covers the entire product supply chain and lifecycle, including manufacturing, transport, and end-of-life recycling. As of 2025, Apple reported a 60% reduction in total greenhouse gas emissions from a 2015 baseline, making it one of the few major technology companies whose emissions are declining rather than rising.
Apple invests in carbon removal, including a Restore Fund focused on forest conservation and sustainable forestry. The company's carbon removal strategy is published and detailed.
iCloud benefits from Apple's infrastructure and renewable energy investments. Files stored in iCloud sit in data centres powered by renewable energy. However, there is no product-specific environmental action tied to an iCloud subscription. Apple's environmental programme applies to the company as a whole.
iCloud provides 5GB free. Plans extend to 50GB at $1/month, 200GB at $3/month, and 2TB at $10/month.
OneDrive (Microsoft)
Microsoft's sustainability commitments are among the most public in the industry. The company pledged in 2020 to be carbon negative by 2030 and to remove all historical emissions by 2050. Investments include direct air capture technology, forest conservation, and soil carbon sequestration. Sustainability reports are detailed and transparent.
The trajectory is concerning. Microsoft's emissions have risen 29% since the 2020 pledge, driven by data centre construction for AI infrastructure. The company has acknowledged the 2030 target is at risk. In 2025, reports showed a further 25% emissions increase year over year. Microsoft is building data centres with wood-based construction and investing in nuclear energy to address future power needs, but these initiatives are years from bearing fruit at scale.
OneDrive benefits from Microsoft's corporate infrastructure. There is no product-specific environmental action tied to a OneDrive subscription. The sustainability investments exist at the company level regardless of product usage.
OneDrive provides 5GB free with a Microsoft account. Microsoft 365 Personal at $7/month includes 1TB of OneDrive storage.
How to choose
If environmental impact is a factor in the choice of cloud storage, the landscape is layered. Apple has the strongest track record of actually reducing emissions. Google and Dropbox have reached renewable energy milestones for their data centres. Microsoft has the most ambitious targets but the worst trajectory relative to those targets. None of them tie environmental action to individual product subscriptions.
Fabric is the only cloud storage provider where every subscription directly funds verified environmental restoration. The mangrove planting is not a corporate pledge or a target for 2030. It is happening now, with every subscriber, documented and audited. For people who want their cloud storage to contribute to something beyond the product itself, Fabric provides that. For the full programme details, see Fabric's environment page.
Frequently asked questions
Does cloud storage have an environmental impact?
Yes. Cloud storage runs on data centres that consume electricity for computing and cooling, and water for temperature management. The environmental cost depends on the data centre's energy source, efficiency, and location. A single user's impact is small, but across billions of users the aggregate is substantial.
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 Google Drive carbon neutral?
Google has matched 100% of its electricity with renewable energy purchases since 2017, but total emissions have risen approximately 50% since 2019 due to data centre expansion. Google Drive benefits from the renewable energy matching, but the company's overall emissions trajectory is moving away from its net-zero 2030 target.
Is Dropbox environmentally friendly?
Dropbox reached 100% renewable energy for its data centres in 2021 and has a carbon neutrality target for 2030. Among the companies on this list, Dropbox has a smaller total footprint due to its smaller scale. The commitments are corporate-wide and not tied to individual subscriptions.
Does Apple offset its carbon emissions?
Apple invests in carbon removal through its Restore Fund and has reduced total emissions by over 60% from its 2015 baseline. Apple's approach focuses on reducing emissions first and removing remaining emissions second, which is considered best practice. iCloud benefits from this, though there is no product-specific environmental programme.
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.
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 checked internally against project plans and reviewed by independent auditors through Veritree. Each tree is recorded individually so it cannot be counted twice. See Fabric's environment page.
Why mangroves?
Mangroves protect coastlines, support marine life, provide livelihoods for coastal communities, and store carbon in sediment for decades. Development and land clearing have destroyed large areas of mangrove forest across the tropics. Restoration benefits the ecosystem, the climate, and the communities who depend on these forests.
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.
