Diginex buys Plan A in €55M deal, reshaping EU carbon tech

Diginex acquires Plan A in €55M bet on Europe’s carbon future

Diginex, a global sustainability and ESG reporting technology provider, has agreed to acquire Berlin-based climate tech startup Plan A in a deal valued at approximately €55 million. The transaction marks one of the most notable exits in Europe’s fast-growing carbon accounting software space and signals an accelerating wave of consolidation as regulators tighten climate disclosure rules across the continent.

Founded in Germany, Plan A built its reputation on a data-driven platform that helps companies measure, report and reduce their carbon emissions. By integrating emissions accounting, decarbonisation planning and regulatory reporting into a single tool, the company became a preferred partner for mid-sized and large enterprises looking to navigate increasingly complex European climate regulations.

Why this deal matters for Europe’s carbon accounting market

Regulation is driving a software arms race

Europe is in the midst of a structural shift in how companies report their environmental impact. New rules such as the Corporate Sustainability Reporting Directive (CSRD), the EU Taxonomy and evolving carbon pricing schemes are forcing thousands of businesses to quantify and disclose their greenhouse gas emissions with far greater accuracy.

This has turned carbon accounting software from a niche tool into a mission-critical system, akin to financial accounting platforms. Companies need auditable, standardised and verifiable data on Scope 1, Scope 2 and Scope 3 emissions. Manual spreadsheets and fragmented tools are no longer sufficient.

By buying Plan A, Diginex is positioning itself as a full-stack provider of both ESG reporting and deep technical carbon measurement capabilities, at a time when demand is being driven not just by voluntary climate pledges but by hard law.

Consolidation is accelerating

The €55 million price tag underscores a broader trend: the European climate software market is maturing. Over the past three years, dozens of startups have launched tools for emissions tracking, life-cycle assessment, carbon removal and climate risk analytics. As the field becomes more crowded, larger players with capital and global reach are starting to buy specialised platforms to fill product gaps and scale faster.

This acquisition suggests that standalone carbon accounting tools will increasingly be absorbed into broader ESG, governance and risk management suites. For corporate buyers, this could mean fewer point solutions and more integrated platforms that tie climate data directly to financial and operational decision-making.

What Diginex gains from Plan A

Deeper carbon expertise and European footprint

Plan A brings a strong base of European clients and a team specialised in carbon methodologies, emissions factors and science-based decarbonisation pathways. Its platform has been designed around European standards and sector-specific requirements, from manufacturing to retail and services.

For Diginex, which has historically focused on broader ESG data and impact reporting, this acquisition deepens its technical capability in emissions modelling and expands its presence in the EU — currently the world’s most demanding regulatory environment for sustainability disclosures.

From reporting to action

One of the most significant shifts in the market is the move from pure reporting to active decarbonisation. Many companies now have baseline inventories of their emissions but struggle to identify which operational changes, supplier decisions or investments will deliver meaningful reductions.

Plan A has differentiated itself by pairing carbon accounting with reduction roadmaps, scenario analysis and sector-specific guidance. By folding this into the Diginex platform, the combined company can offer clients not only compliance-grade reporting but also tools to prioritise and track real-world emissions cuts.

Implications for European corporates and startups

What it means for corporate buyers

For European companies, the deal may bring both benefits and new questions:

• More integrated platforms: Expect tighter links between financial reporting, ESG metrics and carbon data, enabling boards and CFOs to treat climate exposure as a core business risk.
• Higher expectations on data quality: As larger providers like Diginex scale, auditors, investors and regulators are likely to demand more granular, verifiable emissions data.
• Vendor consolidation: Procurement teams may prefer a smaller number of strategic software partners, which could favour platforms that combine ESG, risk and carbon capabilities.

However, buyers will also need to consider data migration, long-term pricing and how quickly new regulatory requirements are incorporated into these platforms. The pace of change in EU climate policy remains high, and software providers will be judged on how rapidly they update methodologies and reporting templates.

Pressure on early-stage climate tech startups

For smaller European climate tech startups, the acquisition is a double-edged signal:

• Proof of exit potential: A €55 million deal validates carbon accounting and decarbonisation software as a viable category for investors and founders.
• Rising competitive bar: With platforms like Diginex plus Plan A offering end-to-end solutions, new entrants will need sharper specialisation — whether in specific industries, advanced AI-driven analytics, or integration with IoT and industrial data.

The likely outcome is a more stratified market: a handful of large, generalist platforms serving multinational clients, complemented by niche tools that solve highly specific problems, from supply chain emissions to product-level life-cycle assessments.

The broader trajectory of carbon accounting in Europe

Europe’s climate agenda is moving from voluntary commitments to enforceable obligations. Boards are facing not just reputational pressure but also regulatory, legal and financial consequences for under-reporting or misrepresenting emissions.

That shift is turning carbon accounting into a core component of corporate infrastructure, alongside ERP systems, financial accounting software and risk management platforms. Transactions like the Diginex–Plan A deal show that investors expect this category to be durable and deeply embedded in how businesses operate.

For Europe, the acquisition is another step in building a homegrown ecosystem of climate and sustainability technology that can both comply with EU rules and set global standards. As more capital flows into the sector and more deals close, the question will shift from whether companies adopt carbon accounting tools to which platforms will define the benchmarks for accuracy, transparency and impact.

For now, the €55 million bet by Diginex on Plan A signals that the race to own the operating system of corporate decarbonisation in Europe is very much underway.
