Most eco-friendly AI tools in 2026
The environmental cost of AI is rising fast, and almost nobody in the industry is doing anything about it at the product level

AI is energy-hungry. Training a frontier model can consume as much electricity as a small town uses in a year. Running one for millions of daily users requires data centres cooled by thousands of litres of water per hour. The industry's electricity demand is projected to rival that of entire countries within a few years. Against this backdrop, the question of which AI tools are environmentally responsible is not academic. It is practical: if you are going to use AI every day, you might as well choose the one that gives something back.
Here is how the major AI tools compare on environmental action, from concrete and verified to nothing at all.

Fabric
Fabric is the only AI tool 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 sign up for.
Local community teams carry out the planting on the Kenyan and Brazilian coastlines. Every site is mapped with GPS coordinates, satellite imagery, and drone footage. Planters document their work on mobile devices with photos, video, and field sensors capturing survival rates and biodiversity. Sites are monitored for three years to ensure the forests 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 are remarkably productive ecosystems. Their root systems hold coastlines together, buffer storm surges, trap carbon in sediment for decades, and provide breeding habitat for fish and crustaceans. Across East Africa, communities depend on these forests for food, work, and income. Replanting restores the ecology and the livelihoods around it simultaneously.
Fabric is working toward being 100% carbon and water neutral by 2030. For the full programme, see Fabric's environment page.
Fabric's AI uses four model families (Gemini, Claude, Grok, OpenAI) and provides AI search across all file types by meaning, a cloud drive with zero disk space, notes and documents, a spatial canvas, and publishing with analytics. The AI can act across 30+ connected apps including Gmail, Slack, Google Drive, and Figma with user approval. Pricing starts at $8/mo billed yearly, with a free tier that includes limited storage and AI.
ChatGPT (OpenAI)
OpenAI has no public environmental sustainability programme. The company does not publish an environmental report, disclose its carbon footprint in detail, or set carbon neutrality targets. There is no product-level environmental action tied to ChatGPT subscriptions.
The environmental footprint is substantial and growing. ChatGPT serves hundreds of millions of weekly users. Each query emits significantly more CO2 than a standard web search. The compute infrastructure runs on Microsoft Azure, whose data centres benefit from Microsoft's corporate sustainability investments, but those investments are Microsoft's and exist regardless of OpenAI.
OpenAI's focus has been on capabilities and safety rather than environmental responsibility. As the most widely used AI tool in the world, this absence is notable.
Google Gemini
Gemini benefits from Google's corporate environmental programme, which is the most documented in the AI industry. Google has matched 100% of its electricity with renewable energy purchases since 2017. Annual Environmental Reports detail emissions, energy efficiency, water use, and waste. The company has invested in clean energy, water stewardship, and data centre efficiency improvements.
The trajectory complicates the narrative. Google's total emissions rose approximately 50% between 2019 and 2024, driven largely by data centre expansion for AI. The 2025 Environmental Report showed improved per-query efficiency (Gemini models are more energy-efficient than their predecessors), but total emissions keep climbing because usage grows faster than efficiency improves.
Gemini benefits from Google's renewable energy infrastructure. There is no product-specific environmental action tied to using Gemini. The renewables and efficiency gains exist at the corporate level regardless of which Google products people use.
Microsoft Copilot
Copilot runs on Microsoft's infrastructure, which carries Microsoft's 2020 pledge to be carbon negative by 2030 and to remove all historical emissions by 2050. Microsoft has invested in direct air capture, forest conservation, and soil carbon projects. The company has built data centres with wood-based construction and is investing in nuclear energy for future power needs.
Microsoft's emissions have risen 29% since the pledge. In 2025, a further 25% year-over-year increase was reported, driven by data centre construction for AI workloads. The company has acknowledged that the 2030 target is at risk. The ambition is substantial. The execution is trailing the growth.
There is no product-specific environmental action tied to Copilot subscriptions. The sustainability programme exists at the corporate level.
Claude (Anthropic)
Anthropic does not publish environmental sustainability information. There is no carbon footprint disclosure, sustainability report, renewable energy commitment, or environmental programme. The company's public focus has been on AI safety research.
Claude's infrastructure runs on AWS and Google Cloud, which have their own corporate-level renewable energy and sustainability commitments. These commitments belong to Amazon and Google respectively and are not specific to Anthropic or Claude.
Notion AI
Notion does not publish environmental sustainability information. The company has no public carbon footprint disclosure, sustainability report, or environmental programme. Notion AI is available as part of the Business plan at $20/user/month.
Notion hosts on AWS, which benefits from Amazon's corporate sustainability investments. These are not specific to Notion.
How to choose
The AI industry's relationship with the environment is mostly one of consumption. The tools consume electricity and water, and the companies behind them range from making substantial corporate investments (Google, Microsoft) to saying nothing (OpenAI, Anthropic, Notion). In every case, the sustainability efforts that exist operate at the corporate level, disconnected from individual product subscriptions.
Fabric is the exception. Every paid subscription directly funds verified tree planting. The impact is documented, audited, and tied to the product itself. For people who use AI every day and want that usage to contribute to something beyond the tool, Fabric provides that.
The trees will not offset the entire environmental cost of AI. What they do is establish that a technology company can build environmental responsibility into the product rather than treating it as a corporate communications exercise. See Fabric's environment page.
Frequently asked questions
How much energy does AI use?
AI workloads are energy-intensive. Training a frontier model can consume gigawatt-hours of electricity. Inference (answering a single query) consumes far less but adds up across hundreds of millions of daily queries. The International Energy Agency projects that data centre electricity demand, driven largely by AI, could double by 2026. Individual AI queries are modest in isolation but significant in aggregate.
What does Fabric do for the environment?
Every Fabric paid subscription plants mangrove trees along the coasts of Kenya and Brazil. The planting is GPS-tagged, photographed, and independently audited by Veritree. 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 any AI tool truly carbon neutral?
No major AI tool has achieved carbon neutrality at the product level. Google and Microsoft have corporate-wide programmes, but both companies' emissions are rising due to AI infrastructure expansion. Fabric is not yet carbon neutral but is working toward it by 2030, and in the meantime, every subscription funds verified environmental restoration.
Does using ChatGPT harm the environment?
Each ChatGPT query has a carbon footprint. Estimates vary, but AI queries consume significantly more energy than standard web searches. OpenAI has not disclosed its environmental footprint or made sustainability commitments. The compute runs on Microsoft Azure, which has its own corporate sustainability programme.
Are Google and Microsoft doing enough?
Both companies have made substantial investments in renewable energy, carbon removal, and data centre efficiency. Both also have emissions that are rising faster than their reduction efforts, driven by AI infrastructure expansion. The pledges are ambitious. The trajectory is concerning. The commitments exist at the corporate level and are not tied to individual products.
Why do mangroves matter?
Mangroves protect coastlines, support marine biodiversity, provide livelihoods for coastal communities, and store carbon in sediment for decades. They are among the most carbon-dense ecosystems on earth. Development and overuse have destroyed large areas of mangrove forest, making restoration both ecologically urgent and socially beneficial.
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 against project plans and reviewed by independent auditors through Veritree. Each tree is individually recorded to prevent double-counting. 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.
