Cracking the Code of Early-Stage Climate Tech Investing

Leveraging ESG Frameworks for Credibility

ESG frameworks are crucial for VCs aiming to position themselves as trusted partners in the climate tech space. They provide a systematic basis for assessing sustainability risks and meeting legal requirements. More and more investors and asset managers are aligning their portfolios with ESG criteria, as they are legally obliged to consider these risks. According to the OECD, integrating ESG considerations is now seen as a best practice for responsible investment and risk management (OECD, 2023).

But ESG frameworks are more than just a compliance tool. They reflect the growing expectations of stakeholders—from lenders and employees to customers and private investors. VCs who master these approaches can not only support startups in raising capital but also secure their long-term competitiveness. This expertise boosts the credibility of VCs and enables them to establish themselves as leading players in sustainable investing. Below, we take a look at the key ESG regulations VCs should know.

Understanding Key ESG Regulations

In Germany, the ESG agenda is largely shaped by the EU. Particularly relevant are the Corporate Sustainable Reporting Directive (CSRD) and the EU Taxonomy Regulation (EU Taxonomy), which set rigorous standards for sustainability reporting and classification of sustainable activities. The CSRD significantly expands reporting obligations. In the future, companies must disclose how they are affected by sustainability risks and the impact their activities have on sustainable development. As a result, the number of companies required to report in Germany will rise from 550 to 15,000—a development that presents both challenges and opportunities for climate VCs.

The EU Taxonomy Regulation defines which economic activities are considered environmentally sustainable. The EU Commission has set technical assessment criteria for around 80 carbon-intensive sectors. For VCs, this serves as a valuable guide when evaluating climate tech startups and ensures investments align with the EU’s Green Deal objectives.

Additional regulations such as the Sustainable Finance Disclosure Regulation (SFDR), the Climate Benchmark Regulation, and the planned regulation on ESG ratings are also relevant. In Germany, the Supply Chain Due Diligence Act introduces further ESG obligations, monitored by the BaFin. Greenwashing remains a central challenge, which regulators are actively combating:

"The ESAs see fighting greenwashing as one of their top priorities."

These regulatory requirements form the foundation for the targeted use of advanced tools such as life cycle assessments and impact modeling, which are increasingly expected by both regulators and investors.

Integrating Life Cycle Assessments and Impact Modeling

Life cycle assessments (LCA) and impact modeling are indispensable tools for improving ESG due diligence processes and building trust with startups. They enable precise, quantitative evaluation of the environmental impacts of investments, supporting well-informed decisions. The US EPA notes that LCA is becoming a standard for evaluating the full environmental impact of products and services (EPA, 2023).

More and more venture firms and startups are incorporating LCA and circular economy practices into their business models. These approaches provide valuable insights into the dynamics of sustainability and growth. By integrating LCA into the investment process, VCs can realign their strategies, develop innovative solutions, and spark important discussions about sustainability and the circular economy across industries. This not only strengthens their credibility but also creates tangible benefits for portfolio companies.

A combination of external ESG ratings and internal ESG data analysis can add depth to investment decisions. This dual approach blends objectivity with industry-specific expertise. At the same time, careful scrutiny of ESG-related claims helps prevent accusations of greenwashing. Shareholder engagement can serve as another tool to motivate companies to sharpen their focus on ESG topics.

Working with Climate Tech Trends

Successful venture capital firms (VCs) stand out by identifying and evaluating climate tech trends early. Europe has established itself as one of the fastest-growing regions for climate tech. Since 2016, investments in this sector have increased sevenfold, reflecting a surge in both innovation and capital allocation (IEA, 2023). Germany, in particular, plays a pioneering role—with a focus on wind power, solar energy, heat pumps, battery technologies, and electrolyzers.

The numbers speak for themselves: In 2023 alone, German companies invested €85 billion to reduce or avoid greenhouse gas emissions. This creates unique opportunities for VCs, especially those who can identify the right sectors and timing for their investments. These trends have a significant impact on where VCs should increase their engagement and demonstrate the scale of climate tech’s economic influence.

Key Sectors in Climate Tech

The climate tech sector encompasses several areas that not only offer growth potential but also present concrete investment opportunities. The most important include Green Mobility, Renewable Energy, Circular Economy, Climate FinTech, Industry Decarbonization, Built Environment, and Agriculture & Food.

• Green Mobility: Demand for sustainable transportation solutions is steadily increasing. For example, Verkor raised €1.3 billion to build a battery cell gigafactory in Dunkirk, which will strengthen the European e-mobility sector from 2025 onward (NREL).
• Renewable Energy: Jolt Electrodes from Barcelona raised €6 million in a Series A round in June 2023. The company develops electrodes for green hydrogen production, aiming to reduce production costs and significantly cut CO₂ emissions (IEA).
• Circular Economy: Nature-inspired technologies are gaining traction here. Anodyne Chemistries received CAD 6.5 million for its platform, which uses bioelectrical processes to produce non-toxic raw materials—processing CO₂ directly at industrial sites (Ellen MacArthur Foundation).
• Agriculture & Food: Infarm invested over $600 million in modular urban farming, highlighting the need for sustainable food systems.

Spotting Trends Early

The key to success lies in identifying trends before they hit the mainstream. Monitoring VC investments in climate tech serves as a valuable market signal that can transform entire industries. In 2024, for example, an impressive 382 venture deals were closed in the clean energy sector, with three out of four deals involving seed and Series A companies. Since 2019, early-stage climate tech startups have also outperformed the rest of the VC ecosystem in funding rounds, underscoring the momentum in this space (IEA, 2023).

Some specialized VCs pursue targeted strategies: Lowercarbon Capital focuses on decarbonization technologies, while Third Sphere invests in companies aiming to redesign global systems. Future Energy Ventures takes a broader approach, supporting companies that solve urban challenges or develop breakthrough technologies.

Industry events and networking remain essential for spotting trends. Growing consumer awareness and demand for eco-friendly products are forcing companies to integrate sustainable practices. At the same time, more corporations are committing to ambitious climate goals such as carbon neutrality, further driving investment in cleantech and climate tech solutions.

Evaluating the Impact Potential of Startups

Beyond trend identification, accurately assessing impact is crucial. Quantifying the potential impact of climate tech startups helps investors select the most effective companies and discover underrepresented categories. The concept of Climate Performance Potential (CPP) enables more informed decisions and targeted investments.

However, over the past eight years, more than 75% of climate-related venture capital has flowed into solutions that cover less than 20% of the potential for emissions reduction. This discrepancy highlights the importance of systematic impact assessment and the need for investors to look beyond the most obvious categories (IEA, 2023).

Third Derivative (D3) offers an example of a structured approach. The company uses a three-step method: first, defining the climate impact type, then setting thresholds, and finally quantitatively assessing impact. D3 distinguishes between “Direct Mitigation Measures” (DMMs) and “Enablers,” setting thresholds from 0.25 Gt to 1.0 Gt CO₂e for global solutions. For startups in developing countries, regional thresholds are calculated as a percentage of total regional emissions.

A central question VCs should ask: If this solution is extraordinarily successful, how great would its potential impact be? Such considerations help ensure investments are targeted and deliver maximum benefit.

Building Authority Through Thought Leadership

In the climate tech sector, VCs gain a clear advantage through thought leadership. With well-researched content, they can not only underscore their value proposition but also support long-term investment decisions. However, about 4 out of 10 decision-makers feel the market is saturated with thought leadership content. Nearly half (48%) want content that challenges existing assumptions and offers fresh perspectives (APlanet). The following section shows how targeted publications and public contributions help further build authority.

Publishing and Public Speaking

Successful thought leadership is based on consistent, original, and practical content. Real-world examples from VCs—such as blogs, newsletters, or podcasts—demonstrate how data-driven content can strengthen visibility and market position over the long term.

“Attention is the new oil. If you're not showing up in the inbox, you're missing the easiest way to stay top of mind with founders, LPs, and everyone in between.”

Podcasts are especially effective, as they showcase not only the expertise of VC partners but also their personalities. They also provide a platform to build relationships with guests. Videos also play an important role: they allow you to combine expertise with personal insights. As early as 2019, 80% of global internet consumption was already video-based.

Collaborating with Trusted Partners

In addition to your own content strategy, partnerships are crucial for building credibility. Collaborations with consulting firms or academic institutions help deepen expertise and develop a more comprehensive understanding of systemic challenges. Especially in climate protection, a systemic approach is indispensable.

Example: Fiegenbaum Solutions supports VCs with expertise in ESG strategies, life cycle assessments, and impact modeling. Such partnerships enable more efficient use of resources, knowledge sharing, and coordinated campaigns.

Sharing Case Studies

Authentic case studies are a powerful way to underline the success of climate investments. Successful VCs use their portfolio companies to make their investment strategies tangible. It’s not just about sharing successes, but also about providing context and exclusive insights.

It’s important for VCs to show which criteria they use to assess impact and how their strategies evolve over time. Personal social media profiles of partners play a decisive role here: they often generate more engagement and deal flow than official company channels. With these measures, VCs lay a solid foundation for the next step: developing concrete tools and structured processes.
