Plan A acquired for €55m. Here are 3 other carbon accounting deals you might’ve missed

Berlin-based Plan A, founded in 2017, builds software that helps companies measure and manage their carbon footprint. The startup cashed-in on the climate tech funding boom to raise about $40m from investors including Lightspeed, HV Capital, Deutsche Bank, and BNP Paribas’ VC arm, Opera Tech Ventures.

Now, it’s being acquired by Diginex, a Nasdaq-listed ESG software provider, in a deal valued at €55m. Diginex will pay €3m in cash plus €52m in shares to take full ownership.

Plan A founder Lubomila Jordanova stays on as CEO.

“Since 2017, my team and I have worked to prove that planetary health and capital performance are not just compatible but inseparable,” Jordanova wrote in a LinkedIn post.

The deal comes at a time of sweeping consolidation in the carbon accounting space, which sprouted hundreds of startups amid the climate tech boom of 2021 and 2022.

In 2025, there were several M&As in the ESG software and carbon accounting. Here are three of the most notable deals you might’ve missed.

Pledge

London-based Pledge was acquired in May by Blue Yonder, an American supply chain management company.

Founded in 2021, Pledge built software that allows enterprises to calculate and report emissions across their logistics supply chains.

The company raised $14.5m in funding, from investors including Bryer Capital, Visionaries Club, and Chris Sacca’s VC fund Lowercarbon Capital.

The deal size was not disclosed.

Matter

Copenhagen-headquartered Matter was one of the first carbon accounting startups to come on the scene.

Like Plan A, Matter was founded in 2017. And also like Plan A, it was acquired by Diginex.

Diginex paid $13m for the startup in the deal, which was finalised in October.

“Joining Diginex unlocks new opportunities to scale our analytics and API solutions globally, providing even deeper insights for sustainable investing,” Matter CEO Niels Fibæk said at the time. “Together, we’re poised to lead the industry in transparent, data-driven sustainability.”

Greenomy

Greenomy, a Belgian sustainability software provider founded in 2020, was acquired by Position Green in September.

Position Green, based in Malmö, Sweden, is one of the larger players in the space. While funding figures aren’t public, it employs over 400 people. The firm has also been on a shopping spree of late.

In addition to its acquisition of Greenomy, Position Green bought two Norwegian companies in 2025: Factline and Morescope.

"This is definitely a way for us to expand faster and more forcefully in Europe," Daniel Gadd, CEO and co-founder of Position Green, previously told Impact Loop. "There are a lot of companies within ESG but we want to be one of the forces who are consolidating the market."
