Why this long-overdue consolidation is the real test of maturity
Diginex's recent acquisition of the German software provider Plan A, which has over 350 corporate clients, is another step in a trend that has already been emerging throughout 2025.
The ESG solutions market is at a turning point. After years of regulatory-driven expansion—triggered by the CSRD, the EU taxonomy, supply chain regulations, and increasing pressure from capital markets—a phase is now beginning that is less forgiving than the early years: selection.
What was long celebrated as a wealth of innovation is increasingly revealing its downside. Today, companies do not have too few ESG tools, but rather too many. And above all, they have too many solutions that operate in isolation, are difficult to explain methodologically, or reach their limits during audits, investment decisions, and management discussions.
From Compliance Tools to Governance Infrastructure
Over the past five years, sustainability software has been developed primarily in response to regulatory requirements. This was necessary—but never the ultimate goal. The market is now clearly moving in a new direction: away from merely meeting specific regulatory requirements, and toward integrated systems that align sustainability with finance, risk management, procurement, and strategy.
A comprehensive market analysis of over 400 ESG and sustainability providers clearly illustrates this transition: compliance → integration → performance. Providers who merely document sustainability are losing relevance. Providers who integrate data, make it auditable, and enable its use in decision-making are gaining strategic importance.
The maturity levels of ESG software
Why Many ESG Tools Fail Structurally
From the perspective of our sustainability consulting practice, a clear pattern emerges that cuts across a wide range of industries: Many ESG tools are functionally impressive—but strategically almost ineffective. They can report, but they cannot explain. They provide numbers, but no priorities. And they work until auditors, finance departments, or executive boards start asking critical questions. In this context, software risks becoming little more than improved storage and task management solutions.
The uncomfortable truth is that ESG software was long designed for sustainability departments, not for corporate management. This is precisely where the current market shakeout comes in.
Our recommendation
A company should no longer evaluate potential ESG tools primarily based on their feature sets, but rather on their ability to answer predefined management questions:
What does a calculated metric mean for risk, investments, and goal achievement?
AI in the ESG Market: Lots of Talk, Limited Value Creation
Hardly any ESG tool today can do without the “AI-enabled” label. In practice, however, its use often falls short of expectations. AI is primarily used for automation: data imports, plausibility checks, and simple text generation. This is efficient—but not transformative.
AI applications that truly add value—such as those used for scenario analysis, forecasting, or decision support—have been rare to date. The reason lies not in a lack of technology, but in a lack of governance: robust training data, transparent models, and clear lines of responsibility are essential in the ESG context—especially when it comes to auditing and liability considerations.
Why many AI features in ESG tools today offer little real value
The current integration of AI into ESG software is usually nothing more than a “smart wrapper” for traditional data automation. Marketing labels such as “AI-supported” or “AI-enabled” often refer to:
- Data Import & Mapping: Many tools use AI to extract data from PDFs, Excel, or third-party systems—while this is efficient, it doesn’t yet result in intelligent output.
- Validation Checks / Anomaly Detection: Automated alerts are helpful—but they do not replace expert judgment and do not provide recommendations for action.
- Text Generation for Reporting & Narratives: Generative AI creates continuous text at the click of a button, but without clear methodological transparency, this remains more automation than true AI intelligence.
The resulting problems are inevitable
- While these functions do improve efficiency, they do not enhance the quality of strategic decision-making.
- AI base modules without governance therefore pose a liability risk in regulated contexts such as CSRD/Assurance because they do not provide audit-proof traceability.
- Black-box models that cannot be explained are not useful for testing and governance processes—and are often excluded in an audit context.
Our recommendations
- Always consider AI evaluations in relation to governance and data model requirements.
- Require providers to be transparent about the source of their data, the training data used, and the interpretability of AI results.
- Ask yourself: Does AI provide insights relevant to decision-making (scenarios, priorities, risks)—or just text and plausibility?
Consolidation in the ESG solutions market: An economically inevitable trend
The consolidation of the ESG tech market, which has been anticipated for years, is no longer a prediction but an economic reality. Three factors are driving this development:
- Scaling challenges: Small providers are reaching their limits when it comes to international rollouts, complex supply chains, and compliance requirements.
- Investor expectations: Private equity-driven approaches favor platforms over standalone solutions.
- Demand side: Companies buy systems, not tools.
The numbers confirm the trend: Market data & growth
The ESG software and sustainability tech market in 2025 shows clear signs of structural consolidation, which is already evident in specific transactions and market value forecasts. For example, in December 2025, the sustainability RegTech provider Diginex signed a binding agreement to acquire Plan A (plana.earth) in order to build an integrated ESG and carbon management platform—a move that exemplifies the trend toward platform formation, in which reporting, CO₂ accounting, and supply chain transparency are combined into a single product.
Market data supports this trend: The global market for ESG and carbon management software is estimated to reach approximately $16 billion by 2025, with projections indicating it will double by 2030 (to approximately $32 billion) and grow to many times that amount (>USD 100 billion)— driven by regulatory requirements and Scope 3 transparency requirements.
At the same time, there are comprehensive M&A lists that openly document several ESG software deals in 2025, such as Connect Earth’s acquisition of Datia in the ESG reporting segment or One Click LCA’s acquisition of Pre Sustainability software—concrete examples of regional consolidation trends in the ESG tech sector.
While the overall M&A market saw a decline in some segments in 2025, the software and IT sectors continue to see active private equity investment, which also strategically targets sustainability and ESG software, thereby confirming market interest in integrated solutions.
The consolidation of the ESG tech market is therefore not just a trend: it is an economic reality, supported by concrete deals and market data.
Consolidation is not a market failure
Consolidation is often interpreted as a sign of an overheated market. In my view, it is the opposite: a sign of maturity. The ESG market is currently undergoing a process of self-regulation. Solutions that do not make a genuine contribution to corporate governance will disappear or be acquired. This is not a loss—but a prerequisite for sustainability to become economically effective.
Our recommendation:
Now is the right time to strategically review ESG architectures—before tool decisions are forced by external factors such as M&A, price adjustments, or product discontinuations. ESG solutions—whether with or without AI—are only strategically relevant if they:
- provides insights relevant to decision-making,
- is capable of governance,
- and supports audit processes.
What this means for businesses in concrete terms
Selecting ESG software is no longer just an IT project. It is an architectural decision with long-term implications for data quality, auditability, and manageability. Going forward, companies should treat ESG systems the same way they treat financial or risk management systems—with clear requirements for integration, governance, and value.
