1. CO₂ Tracking and Reporting Solutions for SMEs

Market Size (< €1 Billion)

The market for CO₂ tracking solutions specifically for small and medium-sized enterprises (SMEs) is an exciting niche that, despite its relevance, has not yet been fully tapped. SMEs contribute about 50% to global greenhouse gas emissions and generate more than half of the EU’s GDP. They are also responsible for around 63% of corporate CO₂ and greenhouse gas emissions, according to StartUs Insights. These figures highlight the enormous potential in this area, especially as SMEs are increasingly under pressure to disclose and reduce their emissions.

The market remains intentionally below the €1 billion threshold, as providers have so far focused mainly on large corporations. Yet demand is clear: 60–62% of SMEs see Net Zero as a priority. However, there are still only a few solutions tailored to their needs. This gap between supply and demand offers a clear opportunity for providers specializing in SMEs, especially as regulatory requirements expand and supply chain transparency becomes a competitive differentiator.

ESG Value Creation Potential

With CO₂ tracking software, SMEs can not only monitor their emissions but also achieve significant cost savings. Efficiency gains reduce expenses by 15–35% while providing reliable emissions data that creates competitive advantages. For example, the petrochemical company Lubritex reduced its reporting costs by 80% using Envify’s AI-powered automation, shrinking reporting time from several weeks to just a few minutes. Previously, manual entries and external consultants were needed, making the process expensive and time-consuming.

Furthermore, 87% of consumers prefer brands that act environmentally responsibly. SMEs that make their CO₂ data transparent can not only attract customers but also avoid regulatory penalties—with a probability of 67%. This consumer trend is supported by research from Deloitte, which found that sustainability increasingly influences purchasing decisions.

Regulatory Drivers

The extended Corporate Sustainability Reporting Directive (CSRD) will increase the number of companies required to report in the EU from fewer than 12,000 to almost 50,000 by 2028. In Germany alone, about 13,000 companies will be affected. This pressure also impacts SMEs that are part of large companies’ supply chains, as larger firms push for emissions data from their partners to fulfill their own obligations (PwC).

The omnibus package limits the reporting obligation to companies with more than 1,000 employees and either revenues over €50 million or a balance sheet total over €25 million. Nevertheless, indirect pressure from supply chain requirements remains. The Carbon Border Adjustment Mechanism (CBAM) also affects SMEs importing carbon-intensive goods into the EU. While smaller importers bringing in less than 50 tons of such goods or under 100 tons of embedded CO₂ emissions per year are exempt, this rule still covers 99% of emissions (European Commission).

Willingness to Innovate

The EU is working on a voluntary sustainable finance standard specifically for SMEs. This standard is intended to make access to green finance easier by using the EU taxonomy’s climate goals as a basis, but simplifying some complex requirements to meet the needs of smaller companies. Learn more about VSME sustainability reporting.

Technologically, much is happening: Modern tools now automate data extraction, emissions calculation, and ESG reporting, significantly reducing manual effort. Many SMEs struggle with environmental reporting because regulations are complex, expertise is lacking, and processes are time-consuming. According to a 2023 OECD report, digitalization and automation are key to overcoming these barriers and enabling SMEs to participate in sustainable value chains.

The use of such sustainability tools is fundamentally changing the approach to reporting: Instead of one-off reports, continuous insights are generated, integrating CO₂ data firmly into decision-making processes. For SMEs, this opens up not only new opportunities but also a clear path to sustainable growth. These technologies show how targeted investments in untapped areas can create real added value and future-proof businesses against evolving regulatory and market demands.

2. Digital Circular Economy for Building Materials

Market Size (< €1 Billion)

The digital circular economy for building materials is an exciting, still underutilized niche market. The construction sector in Germany is responsible for almost half of all waste generated and contributes about 40% to national CO₂ emissions (European Commission). At the same time, the construction industry consumes around 32% of natural resources, while more than 35% of construction and demolition waste ends up in landfills each year (IEA).

Despite these challenges, the market remains below the €1 billion mark, as many players still rely on traditional demolition and disposal methods. Digital platforms supporting material cycles, Building Information Modelling (BIM) for the circular economy, and automated material tracking are not yet widely established. However, this situation offers great potential for sustainable developments and progress in the industry, especially as new regulations and digital solutions begin to shift industry practices.

ESG Value Creation Potential

Digital technologies bring transparency to the value chain, enable tracking of material life cycles, and improve resource utilization. One example is Concular, which has developed a digital building resource passport. This documents the materials used and their CO₂ footprint, greatly facilitating deconstruction and reuse. The company also co-developed DIN SPEC 91484, a standard for recording building products and assessing their reuse potential before demolition or renovation.

Another example is CBRE: By using recycled materials in office outfitting, the company saved almost 315,000 pounds of emissions in 2021. Such initiatives not only reduce environmental impact but also help companies meet growing stakeholder expectations for circularity and transparency (CBRE Global Sustainability Report).

Regulatory Drivers

Regulations play a central role in promoting the circular economy. The EU has introduced the Digital Product Passport (DPP), which records key information such as environmental impact, durability, and recyclability of building products. Since 2022, Berlin has had a regulation requiring circular-oriented deconstruction for public buildings.

In addition, Germany’s National Circular Economy Strategy (NCES) aims to facilitate the transition to a comprehensive circular economy system. The EU also levies a fee of €0.80 per kilogram of non-recycled plastic packaging waste, while Germany plans to reduce municipal waste per capita by 10% by 2030 and by 20% by 2040 compared to 2020. Learn more about EU regulations supporting sustainability.

Willingness to Innovate

Technological development in this area is advancing rapidly. Holcim, for example, is involved in N1, a company that has developed the Site Depot software. This organizes material flows to and from construction sites and shows how much material needs to be newly purchased or can be recycled.

Christian Landes, CEO of N1, explains: “More efficient and economical use of resources in construction is one of the biggest challenges facing the industry. Rethinking processes and developing solutions using artificial intelligence saves construction companies a lot of time and money. Working with Holcim will accelerate Site Depot even further. Having an industry leader on board is a strong signal that we are on the right track.”

Tilo Hahn, Head of Aggregates at Holcim Germany, adds: “The resource source of the future is not just the gravel pit or quarry, but also the demolition site.”

Digital twins also play a central role, modeling processes and determining up to 80% of environmental impacts already in the design phase (McKinsey).

The combination of regulatory pressure, technological progress, and growing environmental awareness creates ideal conditions for digital circular solutions in construction. Companies investing in these technologies now can secure a decisive advantage in a transforming market. These approaches show how digital technologies are actively driving the sustainable transformation of the industry and enabling a more resource-efficient, low-carbon built environment.

3. Energy Efficiency Optimization in Existing Buildings

Market Size (< 1 Billion Euros)

In Germany, almost 35% of final energy consumption is attributable to existing buildings, with 45% of commercial buildings built before 1978. Despite increased renovation costs – a 43% increase since May 2020 – the market for energy efficiency in existing buildings still remains under 1 billion euros. However, the renovation potential remains enormous.

Annual growth of over 7.2% is expected for the commercial building energy efficiency market by 2030. Nevertheless, many building owners hesitate to invest in technologies and solutions. This shows how great the potential for savings and improvement of ESG goals actually is.

ESG Value Creation Potential

Energy efficiency optimizations not only reduce operating costs but also emissions. Depending on the building type, light to medium renovations can reduce energy consumption by 10% to 40%. An analysis of 46,600 buildings revealed that light renovations alone could enable annual savings of $2.9 billion. More comprehensive modernizations that include MEP systems (Mechanical, Electrical, Plumbing) could increase these savings to up to $11.4 billion.

A clear example is provided by the Children's Museum of Pittsburgh: Here, modernizations led to a 58% reduction in energy consumption, while energy costs fell by 60%. Older buildings with lower efficiency classes (F, G, H) consume up to ten times more energy than new Class A+ buildings.

The company Techem impressively demonstrates how great the market potential is. Macquarie Asset Management invested more than 1 billion euros in the development of energy-efficient solutions between 2006 and 2009. By the time of sale, Techem managed around 51 million devices in 11 million apartments in 20 countries.

Frank Hyldmar, former CEO of Techem, emphasized: "Macquarie provided great support in developing Techem into a global industry leader. Its international network and operational expertise helped us transform the company into what it is today."

Regulatory Drivers

Regulatory requirements play a crucial role in promoting energy efficiency. The Building Energy Act (GEG) and the Energy Efficiency Act (EnEfG) set clear incentives. Since January 1, 2024, new heating systems in new buildings or major renovations must be operated with at least 65% renewable energy. Companies with consumption of more than 2.5 GWh per year are required to implement energy-saving measures. For companies with consumption of more than 7.5 GWh, even stricter requirements apply, including the introduction of ISO 50001 or EMAS energy management systems by 2025. Violations can result in fines of up to €100,000.

The Federal Funding Program for Efficient Buildings (BEG) also offers financial support. Subsidies of up to 70% of installation costs are possible, depending on the system:

Innovation Readiness

Digitalization is driving new solutions forward. Building Energy Management Systems (BEMS) are becoming increasingly important as they help use energy more efficiently. Properly implemented systems can reduce energy consumption in new buildings by 10-20% and in existing buildings by up to 30%. Another approach is serial renovation with prefabricated components, which is supported by the federal government. This method is rewarded in the BEG program with a bonus of 15 percentage points.

In typical office buildings, about 40% of energy consumption is attributed to heating, ventilation, and air conditioning (HVAC) systems. Intelligent control systems offer significant savings opportunities here.

The Federal Ministry for Economic Affairs and Climate Action (BMWK) puts it succinctly: "The cleanest and cheapest energy is the energy we don't consume in the first place."

The combination of rising energy costs, strict regulations, and technological advances creates ideal conditions for companies that want to be active in this dynamic market.

4. Local Hydrogen Solutions for Industrial Clusters

Market Size (< 1 Billion Euros)

In Germany, approximately 1.7 million tons of hydrogen are produced annually. Of this, around 60% consists of gray hydrogen or by-products. Current demand is about 55 TWh but could rise to 95 to 130 TWh by 2030. To meet this growing demand, the federal government is investing €154 million in decentralized hydrogen technology centers. Additionally, the National Hydrogen Strategy includes a funding package totaling €9 billion. Despite these efforts, the market for local hydrogen solutions in industrial clusters is currently still below the 1-billion-euro threshold, as the technology is still in its introduction phase.

A central point of the strategy is doubling domestic hydrogen production from 5 to 10 GW by 2030. The reuse of industrial hydrogen, such as that produced in refineries or ammonia plants, plays an important role. This approach serves as a foundation for establishing green hydrogen on a larger scale. At the same time, this development offers significant advantages in the areas of environment, social responsibility, and corporate governance (ESG).

ESG Value Creation Potential

Industrial clusters are responsible for 15 to 20% of global CO₂ emissions, making them an important target for emission reductions. Local hydrogen solutions enable economically viable implementation through shared use of infrastructure and resources for production, distribution, and storage.

Some projects already show how this can work:

• eFarm Nordfriesland started in 2018 with five electrolyzers (2.5 MW) to produce green hydrogen from wind energy for fuel cell trucks and buses.
• The Energy Park Bad Lauchstädt (EBL) has been using a 40 MW wind farm since 2019 to produce up to 1,200 tons of green hydrogen annually. This is stored in underground caverns.
• The GeNeSiS project launched in Stuttgart in 2022 operates four electrolyzers with a capacity of around 10 MW and produces about 1,000 tons of hydrogen per year.

Such projects benefit from regulatory measures that improve the framework conditions for hydrogen solutions.

Regulatory Drivers

Germany's National Hydrogen Strategy (NWS) provides clear guidelines for the production, transport, and use of hydrogen. During the market introduction phase, projects for green hydrogen production receive financial support in particular.

By mid-2023, over 50 projects in Germany were awarded IPCEI status (Important Project of Common European Interest), giving them access to extensive funding. In July 2024, €4.6 billion in subsidies were provided for 23 projects in hydrogen production, transport, and storage. The participating companies contributed €3.3 billion in equity, bringing the total project value to €7.9 billion.

These measures cover the entire hydrogen value chain: from production in electrolyzers (capacity up to 1.4 GW) through storage solutions (up to 370 GWh) to pipeline infrastructure (up to 2,000 km).

Federal Minister Robert Habeck: "Efficient hydrogen infrastructure is crucial to enable the decarbonization of industry and the energy sector."

Additionally, Carbon Contracts for Difference (CCfD) promote industrial decarbonization with renewable hydrogen. Greenhouse gas quotas for fuels in aviation and road transport create further incentives for hydrogen use.

Innovation Readiness

The conversion of coal and steel industries to hydrogen, such as in the Ruhr region, shows the readiness for transformation. Industrial clusters and so-called hydrogen valleys already use by-product hydrogen to support industrial processes and ensure grid stability.

Investments in retrofitting transport pipelines for hydrogen are also continuously increasing. The adaptation of existing industrial processes for hydrogen recovery also holds great potential.

Start-ups, small and medium-sized enterprises (SMEs), and suppliers particularly benefit from this development. At the same time, cross-border clusters are emerging that integrate pipeline, storage, and production infrastructure. All these measures significantly drive the strategic reorientation in the ClimateTech sector.

5. Biogenic CO₂ Sinks and Carbon Farming

Market Size (< 1 Billion Euros)

The market for biogenic CO₂ sinks and carbon farming in Germany is still in its infancy and is well below 1 billion euros. Biogenic CO₂ sinks, as they occur in vegetation, soils, and oceans, as well as carbon farming, which aims to optimize agricultural practices for CO₂ sequestration, offer great potential.

These approaches are gaining increasing importance, as about 25% of global carbon emissions are absorbed by plant-rich landscapes. Oceans make an equally important contribution by also absorbing around 25% of the CO₂ emissions caused annually by human activities. These natural processes form the basis for scalable business models focused on carbon sequestration.

An example of the dynamics in this area is the Carbon Farming CE Initiative. This project is funded with €1.8 million from the European Regional Development Fund and runs from 2023 to 2026. The goal is to support and expand pilot projects for carbon farming in Central Europe. This includes developing guidelines, business models, and monitoring systems. These developments open exciting opportunities for companies focusing on ESG value creation.

ESG Value Creation Potential

Carbon farming has the potential to transform agriculture into a CO₂ sink. Sustainable practices such as cover cropping, no-till soil management, and agroforestry play a central role in binding carbon long-term in soil.

The LIFE Carbon Farming Initiative shows how such measures can be implemented in practice. The project has set itself the goal of reducing the CO₂ footprint of 700 agricultural operations in six European countries by 15% by 2027. Concrete measures include rewetting and restoration of peatlands, use of agroforestry, soil protection strategies, afforestation, and more efficient use of fertilizers.

A 2023 study by the University of California, Davis provides interesting insights: Grassland and pastureland in California prove to be more reliable carbon sinks than forests. The reason lies in their higher resistance to droughts and wildfires. Grassland stores most of its carbon underground, where it remains in roots and soil even during fires. In addition to these ecological benefits, regulatory measures also provide important impulses for market development.

Regulatory Drivers

The EU Regulation on Carbon Removal and Carbon Farming (CRCF) (EU/2024/3012) establishes a voluntary EU-wide framework for certifying carbon removal, carbon farming, and carbon storage in products. The goal is to promote investments in new carbon removal technologies and sustainable carbon farming solutions.

Germany has set ambitious climate goals: Net-zero emissions are to be achieved by 2045. For the LULUCF sector (Land Use, Land Use Change and Forestry), annual targets of 25 million t CO₂-eq. by 2030, 35 million t by 2040, and 40 million t by 2045 are defined.

To achieve this, the federal government is funding research projects on various carbon removal methods (CDR) and sustainable land management practices. Additionally, a National Biomass Strategy is being developed that combines sustainable biomass use, nature conservation, climate protection, and food security. These policy frameworks create the basis for new approaches in this area.

Innovation Readiness

The CRCF regulation relies on modern technologies such as remote sensing through the Copernicus satellite system to reduce costs for measurement and reporting. Innovative methods for CO₂ sequestration include Direct Air Capture, utilization of biogenic emissions, biochar, enhanced rock weathering, and ocean alkalinization.

Digital modeling and remote sensing technologies also play an important role in precisely measuring and verifying carbon removals. At the same time, corporate interest in using carbon farming to generate carbon credits and offset their emissions is growing.

The EU Expert Group on Carbon Removals supports the Commission in developing specific certification methods. These advances could further drive the trading of carbon farming credits on voluntary carbon markets.

6. Smart Grids for EV Charging Infrastructure

Market Size (< 1 Billion Euros)

The market for smart grids in EV charging infrastructure in Germany is still in the development phase and currently remains under 1 billion euros. Together, Germany, the Netherlands, and France provide 69% of public charging points in the EU. By 2030, the federal government aims to register seven to ten million electric vehicles.

A fast charger with a capacity of 150 to 350 kW costs about €50,000, with installation costs accounting for 30-50% of the device price. The "Deutschlandnetz" initiative allocated €2 billion for the expansion of fast-charging stations throughout the country. Additionally, the federal government supports the installation of fast-charging points for cars and trucks with a program of up to €400 million.

Smart Load Balancing plays a key role in making power distribution more efficient, reducing operating costs, and improving user experience. At the same time, German charging networks must meet strict standards.

Iocharger aptly describes it: "Smart Load Balancing (SLB) is the foundation of our future charging infrastructure."

These framework conditions create a solid foundation for ecological and social progress.

ESG Value Creation Potential

Smart grids offer significant savings potential: They can reduce energy costs for consumers and grid operators by 10-15%. At the same time, electric vehicles in regions with high registration numbers could increase peak electricity demand by at least 25% in the next five years. Smart grid technologies help reduce overloads by 10-15%.

An example of efficiency is FLO chargers, which consume 40% less energy in standby mode than standard EV chargers. The electrification of corporate fleets also brings benefits: It reduces direct Scope 1 emissions. A German study from 2022 shows that battery electric vehicles (BEVs) cause higher emissions during production but are significantly cleaner in operation. When using renewable energy, plug-in hybrid vehicles (PHEVs) reduce emissions by 73%, while BEVs reduce them by 89% compared to combustion engines.

Furthermore, smart grids enable real-time monitoring, more efficient energy distribution, and the integration of renewable energy into the charging process. Dynamic pricing based on supply and demand offers additional benefits for EV owners.

The connection between technological developments and sustainable goals is further strengthened by clear regulatory requirements.

Regulatory Drivers

The Charging Station Ordinance and the Electricity Market Act create uniform framework conditions for the expansion of EV charging infrastructure. The Energy Industry Act also enables reduced grid fees for electric vehicles that actively support the grid. At the EU level, subsidized projects are required to use the Open Charge Point Protocol (OCPP 2.0.1), which supports functions such as intelligent load distribution, Vehicle-to-Grid (V2G), and the integration of renewable energy.

Additionally, there are tax incentives for employers who provide charging stations for electric vehicles. The Electric Mobility Act allows municipalities to grant electric vehicles certain benefits such as preferential parking opportunities.

VDA President Hildegard Müller emphasizes: "The planned tax incentives to promote BEVs can provide valuable and sustainable impulses for the market development of e-mobility."

Innovation Readiness

Germany is investing heavily in smart grid technologies as part of the energy transition, with a particular focus on integrating renewable energy. The goal is to install over 1 million public EV chargers by 2025.

A trend in Europe shows an increasing shift to fast-charging stations with higher power capacity – networks are increasingly focusing on units with 350 to 400 kW. At the same time, cybersecurity is becoming increasingly important to ensure the reliability of charging infrastructure. The global market for cybersecurity in smart grids is estimated at $6 billion by 2028.

Vehicle-to-Grid technology (V2G) allows electric vehicles to feed excess energy back into the grid. Additionally, the Law on Digitalization of the Energy Transition has reduced grid fees for electricity suppliers that integrate EVs as energy storage into the power grid.

7. Low-Carbon Process Heat for SMEs

Market Size (< 1 Billion Euros)

The market for low-carbon process heat for small and medium-sized enterprises (SMEs) in Germany remains manageable at less than 1 billion euros. However, more efficient heat generation harbors enormous savings potential: German industry could save up to €21 billion annually. Interestingly, industrial heating applications require as much energy as building heating.

Christian Noll, head of DENEFF, emphasizes: "In Germany, industrial heating applications consume as much energy as building heating – and most of it still comes from fossil fuels."

Through technologies such as heat recovery and process electrification, the energy demand for process heat could be almost halved. However, many SMEs face challenges, particularly in financing and evaluating such projects. Simple methods like payback period are often used instead of more comprehensive approaches like net present value (NPV), which complicates decision-making. However, these savings could not only reduce operating costs but also create ESG benefits, which are examined in the next section.

ESG Value Creation Potential

Globally, SMEs contribute more than 60% to greenhouse gas emissions. Small companies in the US alone cause about half a billion tons of CO₂ annually. Investments in energy-efficient technologies such as heat pumps, solar systems, or modern lighting systems offer not only cost savings but also significant efficiency benefits. Low-carbon process heat is a central component of sustainable industrial transformation. This transformation considers ecological aspects (energy efficiency), social responsibility, and optimized corporate governance.

Despite the advantages, long payback periods and lack of capital hinder investment readiness. According to CDP, 23,487 environmental disclosure requests were sent worldwide in 2021, of which 11,457 were answered. These figures show that there is still much room for improvement.

Regulatory Drivers

The revised EU Energy Performance of Buildings Directive (EPBD) envisages achieving a fully decarbonized building stock by 2050. By 2030, primary energy consumption of residential buildings should be reduced by 16% and by 20-22% by 2035. From 2025, no financial incentives will be granted for fossil-fueled individual boilers. Such requirements specifically promote the implementation of efficiency measures.

The new German government coalition is also driving industrial transformation forward. Plans include rapid expansion of hydrogen infrastructure and competitive energy prices. A Germany Fund with at least €10 billion in federal capital is to support SMEs and scale-ups, while €100 billion from the Climate and Transformation Fund (KTF) will flow into industrial decarbonization.

The coalition emphasizes: "In the ramp-up phase, we will use all colors of hydrogen."

The new Building Energy Act is described as "technology-neutral, more flexible and simpler." The focus is on reducing CO₂ emissions.

Innovation Readiness

To overcome existing barriers, SMEs are increasingly relying on new financing and technology solutions. The state supports the use of low-carbon technologies through climate protection contracts linked to location commitments. Building a hydrogen backbone connecting industrial centers in southern and eastern Germany, as well as introducing a special electricity price for energy-intensive industries, are further important steps.

For SMEs, using modern capital budgeting approaches like the NPV model offers an opportunity to make more informed investment decisions. This approach considers the time value of money and enables a long-term perspective. Municipalities also play a crucial role: They mediate between supply and demand for low-carbon heating solutions. The exchange of experiences between larger and smaller municipalities, increased use of district heating from renewable energy, and re-municipalization of utility companies can further accelerate the transition.

8. Climate-Friendly Refrigerants and Cooling Systems

Market Size (< 1 Billion Euros)

The German market for climate-friendly refrigerants and cooling systems remains manageable with a volume of under 1 billion euros. Nevertheless, the refrigeration technology industry is growing annually by 7.8%, even though climate-friendly systems often require up to 30% higher initial investments. Already in 2023, more than 75% of newly introduced commercial refrigeration equipment was equipped with R290-based systems. More and more companies are using natural refrigerants such as propane, isobutane, and CO₂. This development brings not only economic benefits but also noticeable improvements in the areas of environment, social responsibility, and corporate governance (ESG).

ESG Value Creation Potential

Climate-friendly refrigerants offer clear advantages for companies investing in this area. According to current estimates, about 9 billion tons of CO₂ equivalent in the form of old CFC refrigerants are still in circulation worldwide. Companies that switch early to systems with low Global Warming Potential (GWP) can not only increase the efficiency of their systems but also significantly reduce refrigerant emissions.

JSI Store Fixtures emphasizes: "Switching to environmentally friendly refrigeration technology is more than a technical update – it's an opportunity to reduce risks, strengthen your brand, and build a business prepared for the future."

Early conversion to modern cooling systems also avoids high costs for using outdated refrigerants.

Regulatory Drivers

Strict requirements at EU and national levels drive the shift toward climate-friendly refrigeration technology. The EU F-Gas Regulation (EU) 2024/573, which came into force on March 11, 2024, is a central instrument for promoting environmentally friendly refrigerants. Germany takes a pioneering role here and has set the goal of reducing fluorinated gas emissions by 70% by 2030. The regulation provides for a gradual reduction of hydrofluorocarbons (HFCs), with the long-term goal of completely phasing out their availability by 2050.

Some measures are already taking effect: The use of R134a in new refrigeration systems in Europe will be completely banned by 2025. Additionally, the German government supports the transition through funding programs such as the Refrigeration-Climate Directive, which financially supports investments in stationary refrigeration and air conditioning systems with non-halogenated refrigerants.

Innovation Readiness

Strict regulatory requirements significantly increase innovation pressure in the industry. Germany has positioned itself as a pioneer here, particularly in the development of R290 systems and CO₂-based solutions. Companies are increasingly investing in research and development to create cooling systems that meet European standards.

For successful conversion, companies should first conduct an inventory of currently used refrigerants and develop a clear strategy for switching to alternatives with lower GWP. Equally important is finding sustainable solutions for disposing of used refrigerants.

Particularly in focus are innovative systems for precise temperature control that use natural refrigerants while ensuring high energy efficiency.

9. ESG Data Integration for Supply Chains

Market Size (< 1 Billion Euros)

The German market for ESG data integration in supply chains is still small with a volume of under 1 billion euros, but offers great potential. About 40-50% of small and medium-sized enterprises (SMEs) do not integrate ESG data, although 88% of executives identify poor data quality as one of the three biggest ESG risks. At the same time, the market is growing steadily, as 1,255 new ESG regulations have been introduced worldwide since 2011. This gap in data management opens opportunities to realize both economic and ecological benefits in supply chains.

ESG Value Creation Potential

The integration of ESG data can positively influence growth and returns for shareholders. Already 83% of investors consider sustainability information in their investment decisions.

An example is provided by EnerSys, which integrated generative AI into its ESG data processes in 2024. This automated the extraction and analysis of electricity bills at 180 locations worldwide, significantly improving accuracy and efficiency in tracking Scope 1 and Scope 2 emissions. L'Oréal also shows how ESG data can be effectively used: Together with Eviden, the company developed the EcoDesign Cloud, a tool for assessing the environmental impact of retail and advertising materials. This solution provides detailed insights into the carbon footprint of store elements and supports suppliers in making more environmentally friendly decisions.

Regulatory Drivers

Regulatory initiatives such as the German Supply Chain Due Diligence Act (LkSG) and the EU Corporate Sustainability Due Diligence Directive (CSDDD) significantly drive ESG data integration. These regulations require companies to monitor and manage human rights and environmental protection throughout the entire supply chain.

The potential sanctions are considerable: The LkSG provides for fines of up to €800,000 or 2% of average worldwide annual turnover, while the CSDDD imposes penalties of at least 5% of worldwide net turnover. The CSDDD will affect about 13,000 companies in the EU and another 4,000 companies outside the EU.

Stefan Kornelius, government spokesperson, explains: "As part of the EU Commission's reform efforts to streamline bureaucracy, the goal is also to streamline the European Supply Chain Directive in its comprehensive impact."

Innovation Readiness

Strict regulatory requirements increase pressure on companies to develop innovative solutions. However, structural barriers complicate implementation. 92% of executives in energy, utility, and commodity companies emphasize the importance of supply chain strategies for ESG goals. At the same time, 84% of respondents see lack of digital competencies as the biggest challenge in ESG integration.

To overcome these challenges, companies should centralize their risk management and compliance structures. Particularly important is consolidating ESG data in a platform. This reduces data fragmentation and accelerates reporting. The development of ESG data integration can also be linked to untapped markets in the ClimateTech sector.

10. AI-Supported Climate Risk Analysis for Companies

Market Size (< 1 Billion Euros)

The German market for AI-supported climate risk analysis is still in its infancy with a volume of under 1 billion euros. According to Bain & Company, natural disasters could cost up to 4% of global GDP by 2050. At the same time, the growing use of AI is expected to significantly increase IT-related CO₂ emissions by 2030. These developments highlight the need for intelligent solutions that not only precisely assess climate risks but also consider the ecological footprint of the technologies used.

An example of such solutions is Jupiter Intelligence, which launched the Jupiter AI platform in June 2024. This platform helps companies switch from reactive to proactive environmental management to identify and prevent potential environmental damage early. Such approaches offer companies clear advantages in meeting ESG criteria.

ESG Value Creation Potential

AI-supported climate risk analysis opens new possibilities for achieving ESG goals. It improves data processing, enables real-time risk identification, and provides more precise predictions. A survey shows that 64% of investors support higher spending to reduce CO₂ emissions, while almost three-quarters prefer companies that implement concrete climate measures.

The technology helps make informed decisions in areas such as energy investments and supply chain management. For example, AI-based fraud detection reduces ESG misclassification rates by 30%, and hedge funds using such models achieve 15% better performance than traditional ESG funds. A clear example is the Dieselgate scandal: AI models could detect inconsistencies in Volkswagen's emissions data long before regulators intervened. This shows how effective AI can be in revealing discrepancies between reported ESG goals and actual performance.

Regulatory Drivers

In addition to the benefits for ESG goals, regulatory requirements also play a crucial role. The EU AI Regulation highlights environmental protection as one of its central goals and contains specific rules on sustainability. Additionally, the EU Energy Efficiency Directive (EED) requires data centers to create more transparency about their energy efficiency. In Germany, the Energy Efficiency Act implements this directive and introduces a national reporting system that sets additional requirements such as efficiency and renewable energy targets for data centers. These requirements create a clear foundation for integrating AI into climate risk analyses.

Market Comparison Overview

The ten ClimateTech markets differ significantly in their size, ESG potential, and regulatory importance – all factors that are crucial for strategic investments. This is particularly relevant as Germany aims to become greenhouse gas neutral by 2045 and has set interim targets such as a 65% emission reduction by 2030 and 88% by 2040 (compared to 1990). This diversity forms the basis for the subsequent market-specific considerations.

A look at the analyses shows: The area of energy efficiency in existing buildings is developing particularly dynamically. Strict requirements and high modernization needs drive this market. In contrast, markets such as biogenic CO₂ sinks grow more slowly, although they offer great ESG potential. The reason lies in the not yet fully established regulatory frameworks.

Digital solutions – for example for ESG data integration or AI-supported climate risk analyses – have the advantage of being quickly scalable. In contrast, hardware-intensive approaches, such as local hydrogen projects or process heat optimization, require high initial investments. Nevertheless, the influence of the ClimateTech industry in Germany is already clearly visible: It contributes 15% to the gross domestic product, and every third German startup is active in the green economy.

Regulatory requirements such as the CSRD and the LkSG create additional incentives for digital ESG solutions. At the same time, BaFin requires regulated companies to integrate climate risks into their risk management processes. This increases demand for AI-supported climate risk analyses. Additionally, instruments such as Carbon Contracts for Difference (CCfDs) promote climate-friendly production methods.

Bernd Heid from McKinsey puts it succinctly: "We know these technologies; it's not that we have to invent new technologies. The problem is that they are not scaled yet."

This market analysis provides companies with clear starting points for early investment in promising technologies while simultaneously advancing their ESG goals.
