How Greenly Supports 3,500+ Companies in Measuring & Reducing Their Carbon Footprint

Earth Day 2026

On Earth Day 2026, Greenly — a global leader in emissions tracking — released data from over 3,500 companies that paints a clear picture: corporate climate action is accelerating, not retreating. With 280 million tonnes of CO₂e under management and €20 million in ARR now surpassed, the numbers confirm that the carbon shift in business is no longer a trend — it's a structural transformation already well underway.

Public debate around climate commitments may be growing louder and more contentious, but on the ground, inside the finance teams, procurement departments, and boardrooms of thousands of companies worldwide, a quieter revolution is taking shape. Carbon data is becoming a core performance metric, as routine and as critical as revenue figures or operating margins.

That's the central message from the Earth Day 2026 release published by Greenly, the Paris-based climate tech software company founded in 2019 that offers an all-in-one sustainability platform. The firm, which supports more than 3,500 organisations across more than 20 countries, has published one of the most comprehensive snapshots of real-world corporate climate action available today.

What Greenly's data tells us about the corporate carbon shift

Greenly's platform currently monitors 280 million tonnes of CO₂ equivalent, roughly 50% of France's entire annual carbon footprint. This covers the full spectrum of corporate emissions:

Scope 1 (direct emissions from operations),
Scope 2 (indirect emissions from purchased energy),
Scope 3 (value-chain emissions, which typically represent the vast majority of a company's footprint).

More importantly, this data is no longer being collected just to satisfy regulators. The shift is visible in the numbers: based on actions implemented by clients, Greenly has identified 6.7 million tonnes of CO₂e in emissions either reduced or avoided.

Carbon is gradually establishing itself as a core performance indicator alongside financial and operational metrics — this reflects a structural transformation, not a reporting exercise.

It also confirmed it has surpassed €20 million in annual recurring revenue in 2026, more than doubling from the $10 million ARR it recorded at the time of its Series B fundraise. The wider carbon accounting market mirrors this momentum: the sector is expected to grow from USD 23.53 billion in 2025 to nearly USD 30 billion in 2026, and is forecast to reach USD 97.58 billion by 2031.

A cross-sector movement, not a niche one

One of the most significant findings is how broad the adoption has become. The 3,500+ client base now spans industries not historically associated with leading on environmental issues:

The platform serves companies from SMEs to larger corporations including companies across finance, technology, and consumer sectors and provides advisory services helping clients interpret regulatory requirements, define science-based reduction targets (SBTi), and implement practical decarbonisation plans. Its approach has also created a vast database of emission factors from data of more than 20,000 suppliers, fostering powerful network effects throughout the supply chain.

AI and automation: Making Scope 3 finally tractable

The hardest part of corporate carbon management has long been Scope 3, the emissions that happen outside a company's direct operations, deep in the supply chain. These typically account for more than 70% of a company's total footprint, yet they're the most difficult and time-consuming to track.

Greenly's EcoPilot platform automates this process — collecting, structuring, and processing carbon data by automatically importing physical inventory, accounting, and logistics data; applying proprietary algorithms; and assigning emissions factors with a high level of accuracy. Its AI-driven modules analyse emissions hotspots and model "what-if" scenarios such as switching transport modes or changing suppliers. Reporting tools then produce audit-ready deliverables compliant with CSRD, CBAM, ISSB, and other evolving standards.

The bigger picture: Carbon as a business language

Earth Day 2026's theme is "Our Power, Our Planet" , a reminder that environmental leadership doesn't always come from the top down. But what the data suggests is that it is also increasingly coming from inside companies, driven not just by values but by investor expectations, regulatory requirements, and competitive pressure.

Carbon is becoming a language that business speaks fluently. And with Greenly tracking hundreds of millions of tonnes across thousands of companies on every continent, the era when sustainability was a side note to the annual report is firmly over. .

On the evidence of this Earth Day report, that future may arrive sooner than many expect.
