Have you ever heard of cleantech? 🤔 In 2024 alone, EU cleantech investment reached €23.4 billion across 76 deals—nearly tripling the previous year’s total. A historic first quarter accounted for €16.9 billion of that investment, fueled by mega-deals and increased backing from public financial institutions. Notably, cleantech venture capital (VC) activity spanned 23 of the 27 EU member states, highlighting the growing traction across the continent.
In the same year, €8.8 billion in venture capital was directed towards clean technologies, sparking a wave of sustainable technology innovations that are set to revolutionize various industries, including construction. In this article, we’ll explore how clean technologies are being applied in the building sector and why VC investment is essential to driving the next generation of green infrastructure. Let’s go!
First things first. Before we get into cleantech investment and what it all involves, let’s take a moment to break down what this term really means.
Cleantech (Short for “clean technologies” has grown beyond niche sustainability circles in recent years and is now gaining more traction than ever across mainstream industries. In simple terms, this concept refers to a broad range of technologies and companies focused on improving environmental sustainability. We’re talking about innovations and business models that tackle global challenges like climate change and resource depletion.
The cleantech umbrella covers a wide variety of products (such as solar panels and low-carbon cement), services, and processes across different sectors (energy, construction, transportation, materials, and chemicals, among others), all designed to:
As the construction industry intensifies efforts to reduce carbon emissions and lessen its environmental footprint. Cleantech is emerging as a key driver of sustainable transformation. Startups and leading construction firms are actively investing in and adopting clean technologies that promote eco-friendly building practices.
Cleantech in construction focuses on improving energy efficiency, reducing waste, and lowering emissions across the entire building lifecycle—from design and material selection to construction methods and operational performance. By integrating these solutions, the building industry is not only addressing environmental challenges but also unlocking new opportunities for cost savings and long-term value.
In our recently published Top 50 Contech 2025 Report, the investment experts at Cemex Ventures shared some of the most valuable insights on the trajectory and outlook of cleantech investment throughout 2024. Amid a slowdown in venture capital activity, construction-related clean technology also saw a 15% drop compared to 2023 (2023: US$54B, 2024: US$46B). While this decline reflects ongoing market challenges, it also points to a window of opportunity for the adoption of breakthrough technologies in 2025. The Cleantech sector within the building environment has shown adaptability with a growing influx of investment driven by substantial public subsidies and increasing private sector interest in this field.
Fast forward, let’s dig into the information about the intersection of Contech and Cleantech in Q1 2025 — that is, solutions applicable to Contech which, due to their sustainability angle, CO2 mitigation, etc., can also be considered Cleantech. During this period, the sector reached an invested amount of USD 466.44M across 23 deals — a 93% and 44% increase, respectively, compared to 2024 (USD 241.19M invested across 16 deals).
The computational power required to support AI’s rapid growth is doubling roughly every 100 days. This surge is driving a sharp rise in the number of data centers being built around the world, along with the energy needed to run them. As a result, AI and data centers are becoming major drivers of global electricity demand.
But it’s not just about how much energy is used, it’s also about when and where it’s needed. Data centers require a constant, stable power supply 24/7, which puts pressure on efforts to reduce emissions. This is sparking a global race to secure data center locations that offer abundant, clean, and reliable energy at scale.
Over the past year, major tech companies have ramped up investment in advanced nuclear technologies, from small modular reactors to fusion. These long-term solutions show promise, but most won’t be ready to deliver energy until the 2030s.
The construction industry is shifting toward a more sustainable approach. Low-carbon construction aims to make building processes less harmful and more aligned with the environmental goals of the Paris Agreement.
Several startups are also embracing cleaner, more sustainable materials—commonly known as green building materials—such as hemp-based concrete, bamboo, precast concrete, mycelium, and recycled plastic, among others.
The clean energy sector has been consistently innovating, and this momentum is expected to accelerate even more in 2025. This trend is evident in the growing investments and increased public funding for energy research and development, aimed at improving technical performance and efficiency, reducing costs, advancing emerging technologies, and inventing the solutions of the future.
Mature technologies like solar photovoltaics and wind turbines have already undergone this transformation over the past decades. Now, emerging technologies such as batteries and carbon management solutions are following their own innovation trajectories—driven by even greater urgency and rapid growth.
Yes, at Cemex Ventures, we’ve totally clicked with cleantech. We’re all in on leading the construction industry’s shift toward a greener, cleaner future. Our team of investment pros is constantly on the lookout for the most disruptive clean technologies that can cut CO2 emissions and boost the circular economy. That’s why our investment portfolio proudly showcases what green construction is all about.

Construction Startup Competition (teamed up with industry giants like Caterpillar, Hilti Group, Ferrovial, VINCI Group’s Leonard, Haskell’s Dysruptek, and Zacua Ventures) is open for applications until June 22.
This is your chance to skyrocket your startup into a top-tier ecosystem of investors and major companies!
Although they’re called ‘unicorns’ for their supposed rarity, there are more than you’d probably imagine—as of January 2025, there are over 1,200 unicorns globally (privately held companies valued at more than US$1 billion). Once just another unicorn, now household names—think Airbnb, Facebook, or Google.
Even the giants we know today began as early-stage startups. In this article, you’ll find everything you need to know about startup funding.
💡 Remember: Every major company started with a great idea and the right funding. Your breakthrough could be next!
Let’s start with the basics: startup funding refers to the process of raising capital for new established businesses. It’s a key stage in a startup’s life cycle, providing the necessary resources to launch, scale, and grow the business, essential for covering initial costs, scaling operations, and achieving milestones that attract further investments.
Do you need funding for your startup? Early-stage businesses typically raise funding from a variety of sources. Here are the 6 most common types:
Angel investors are usually wealthy individuals who risk their own money to invest in startups, mostly in exchange for an ownership stake or convertible debt. Angel capital typically funds activities such as prototype development, market research, and initial hiring. Angel investors play a critical role in validating the startup, providing capital to prove the concept and signaling confidence to other investors.
Angels usually have prior industry or entrepreneurial experience, offering mentorship and guidance to founders they support. Their involvement helps startups navigate early challenges and refine their strategy. Additional benefits of angel financing include:
🚨 Caution: Angel investors expect involvement. Choose those aligned with your startup’s vision and growth strategy.
Venture capital, also known as VC, is a financial tool that helps businesses grow, offering institutional investors opportunities in emerging companies. Startups benefit by securing funding, refining business models, and exploring new markets through this short-term capital injection. VC investors typically have a strong economic focus, negotiating terms for equity in the company.
VC firms raise funds to invest in both early-stage and mature startups. They often prioritize performance metrics and financial potential when assessing investments.

CVC is the practice of established companies investing in external startups to drive innovation and strategic growth. Often, startups approach these corporations to test technologies, explore joint developments, gain new customers, and secure funding.
One significant advantage of corporate venture capital is helping startups break into new markets, utilizing the corporation’s network. Additionally, startups receive support in legal advice, communications, marketing, or access to facilities tailored to specific collaboration needs.
🤝 Pro tip: Align your startup’s objectives with the strategic goals of your corporate partner to maximize mutual benefit.
Bootstrapping is a self-financing approach where entrepreneurs use personal savings, initial sales revenue, or loans without external investors. Founders retain complete control over business decisions, avoiding equity dilution.
However, bootstrapping requires careful planning, resourcefulness, and patience, potentially limiting rapid growth opportunities.
In short, accelerators help entrepreneurs turn their knowledge into action. These are cohort-based programs that offer mentorship, services, education, networking, and recognition to early-stage startups looking to scale their product or service quickly. They are considered a form of early-stage financing because they often provide seed funding for startups.
Crowdfunding platforms let startups raise small amounts of money from many individuals, usually via online campaigns.
Backers might receive rewards, equity, or debt. These platforms allow entrepreneurs to showcase ideas to wider audiences, validate market interest, and gain early customer feedback.
📢 Quick tip: Crowdfunding is more than funding—it can validate your product and build your community from day one.
First things first: seed funding is the initial capital an early-stage startup raises to advance toward the next growth stage. Known also as seed capital or seed money, it’s typically the first formal institutional fundraising round. Seed investors are willing to take big risks on early-stage companies for potentially high returns.
Seed funding mainly serves to validate business ideas and move towards a functioning business. Startups are considered ready for seed funding when they can demo their product, even if further development is needed to reach a minimum viable product (MVP) or proof of concept.
Pitch meetings allow startups to present their business model and vision to potential investors. Crafting a compelling investor pitch is crucial during fundraising—investors see countless pitches, and few stand out. A successful pitch is clear, concise, memorable, tells a compelling story, addresses key concerns, and excites investors.
When a pitch leads to a term sheet, leverage insights from fundraising benchmarks and financial models to negotiate favorable terms. Involve legal counsel to ensure fairness and market alignment.
⚖️ Advice: Always review term sheets carefully. Good negotiations now can significantly impact your startup’s future.

Is prefabrication the key to solving 21st-century construction challenges?
Prefabricated buildings are making waves as a sustainable breakthrough today, but what does this construction method really involve? Let’s take a closer look!
Prefabrication, as the name suggests, involves assembling building components off-site before transporting them to their final location for installation.
In traditional construction, raw materials are brought to the site, where everything is built from the ground up. Prefabrication flips this approach—only the foundation is constructed on-site, while key sections are pre-built elsewhere and then delivered for assembly.
Fun fact: In civil engineering projects like bridges and dams, steel frameworks as long as 37 meters are often prefabricated and transported to the site, streamlining construction and reducing on-site work.
The main difference between modular, prefabricated, and industrialized construction lies in how and where building components are manufactured and assembled:
In short, while prefabricated and modular construction focus on where and how building components are manufactured and assembled, industrialized construction takes a broader approach: It prioritizes efficiency, automation, and standardization by integrating advanced technologies and streamlined industrial processes to optimize the entire construction workflow.
Prefabricated construction might seem like a modern trend, but its roots go back thousands of years. As early as 2600 BCE, the Egyptians used pre-cut stone blocks to construct the pyramids, allowing for more efficient building processes. The Romans later advanced this concept by incorporating prefabricated architectural elements such as columns, arches, and domes, which helped them construct massive structures more quickly and consistently.
In the 20th century, prefabrication became a game-changer, especially after World War II. With millions of people needing housing, factory-made building components—like entire wall panels, floors, and roofs—were mass-produced and transported to construction sites for rapid assembly. This approach significantly reduced construction time and costs, making prefabrication a key solution for post-war rebuilding efforts.
For a bit more context, it’s interesting to note that prefab building and modular construction have taken a step back in recent years. However, the prefabricated construction market was valued at US$146.4Bn in 2024 and is expected to reach US$208.1Bn by 2030.
This market is growing rapidly, driven by urbanization, cost efficiency, and the demand for scalable infrastructure, especially in emerging economies like India and China. The Asia-Pacific (APAC) region holds a major share, fueled by construction activity, labor shortages, and government support for affordable housing. Europe and North America are also expanding, with prefabricated construction gaining traction in commercial and residential sectors.
➡ You may be interested: The main trends in the construction world for 2025
Prefabrication is often faster than traditional construction because the components arrive pre-built and only need to be assembled on-site. It can also be more cost-effective. Since prefabricated components are manufactured in a controlled factory environment, transporting them is often cheaper than moving raw materials and assembling everything on-site.
➡ Prefabrication can reduce construction time by up to 50%!
Building more sustainably starts with rethinking how we construct. Traditional methods rely on frequent material transport and generate significant waste. In contrast, prefabrication centralizes production in a factory, reducing its environmental impact.
Prefabricated construction has become a versatile choice for a wide range of building projects. Here’s how:
At Cemex Ventures, we bet on technologies and trends that can help solve the challenges in the construction industry.

Are you an entrepreneur with a disruptive prefab construction solution that’s redefining the industry’s future? Get in touch with our investment team now.
This is a wake-up call: Without any abatement measures from the building materials sector, global demand for concrete – the most widely used material in the world – is projected to generate 3.8 gigatons of CO2 emissions annually by 2050. Cement production—one of concrete’s key components—accounts for 8% of global CO₂ emissions yearly.
The future competitiveness of the global cement industry will hinge on who can reduce their carbon footprint the most. A groundbreaking innovator is reshaping cement production in construction with sustainability leading the charge and has now made its way into our investment portfolio to stay: Say hi to Terra CO2.
Simply put: Terra CO2 is a Colorado-based startup that has developed a scalable, low-carbon alternative for replacing cement in concrete.
The American startup produces supplementary cementitious materials and carbon-neutral cement to meet the vast demand, making decarbonized concrete a practical and accessible solution for the construction industry. Terra CO2 offers two standout products:

Madrid, Spain. March 25, 2025. Cemex announced today its most recent investment in climate-friendly & zero carbon cement company, Terra CO2, carried out through its corporate venture capital (CVC) and open innovation unit, Cemex Ventures. Concrete is the world’s second most used material, next to water. The production of cement—a key component of concrete—is responsible for a significant share of global CO2 emissions annually, thus reducing related emissions in its production process is a critical climate priority for the building sector.
Terra CO2, an American-based company, produces supplementary cementitious materials and carbon-neutral cement that are scalable to meet the massive demand, making decarbonized concrete a practical and affordable solution for the construction industry. Terra’s first product, OPUS SCM™, is an engineered Supplementary Cementitious Material (SCM) made from abundant and cost-effective silicate rock feedstock, capable of reducing up to 70% CO2 emissions when partially replacing clinker or other traditional cementitious products. Their second product is OPUS ZERO™, a 100% cement replacement solution now in full concrete trials. The breakthrough company was granted additional support in 2024 by the U.S. Department of Energy (DOE), for the deployment of its clean technology.
“Our path to carbon neutrality is stronger than ever. Terra CO2 has emerged as one of the most relevant technologies in today’s market for reducing the carbon footprint at a competitive cost, making it the ideal partner for Cemex,” said Alfredo Carrato, Investment and Open Innovation at Cemex Ventures. “We are thrilled to highlight the synergy with this high-potential Cleantech solution validated by key industry players, as we continue driving the revolution in construction and leading it toward a more sustainable future.”
“Having one of the world’s leading cement producers invest in Terra CO2 validates our technology and its role in decarbonizing the industry,” said Bill Yearsley, CEO of Terra CO2. “Our approach has always been that to achieve decarbonization of cement; we need to create solutions that work as seamlessly as possible within the existing industry infrastructure. We look forward to working alongside Cemex to integrate sustainable solutions that do not disrupt our industry.”
Following this initial investment, Cemex aims to integrate Terra CO2’s portfolio of solutions across its operations in the Americas and Europe, positioning the global building materials company as a leader in carbon reduction within the building materials industry. The American startup aims to help Cemex reduce its Scope 1 CO2 emissions, targeting the direct greenhouse gas emissions generated by its production processes. This investment bolsters the ambitious climate action goals set out by Cemex’s sustainability and decarbonization program, Future in Action, through its Innovation & Partnerships pillar.
