“Greening” manufacturing enterprises, it doesn't start with money, but with data

In the global race toward sustainability, manufacturing enterprises hold a massive, often-overlooked treasure: data. Every day, thousands of data points about energy consumption, raw materials, and production processes are generated only to remain dormant in unread reports. These neglected data sets actually contain the key to the most effective green transformation without the need for billions in new equipment investment. But how can businesses unlock this hidden potential?

1. Why Does "Greening" Require a New Perspective?

1.1 Global Green Transition Pressures and Demands from International Partners and Markets

Amid growing global environmental pressures, the green transition has become an urgent imperative for manufacturing and export-oriented enterprises.

First and foremost is the increasing wave of regulatory requirements. For example, the European Union’s Carbon Border Adjustment Mechanism (CBAM) will take effect on January 1, 2026, mandating that businesses report and reduce embedded carbon emissions in their products or face carbon tariffs.

Simultaneously, a host of new regulations such as Extended Producer Responsibility (EPR), the U.S. Toxic Substances Control Act (TSCA), and plastic packaging taxes are being introduced. These measures compel businesses to swiftly adapt or risk being excluded from global markets and facing significant financial penalties.

In addition, international markets and partners are raising the bar for sustainability standards. Consumers increasingly prioritize environmentally friendly products, while multinational corporations and financial institutions are embedding ESG (Environmental, Social, and Governance) criteria into their supply chains and investment decisions. Green manufacturing is no longer just a way to meet market expectations it is a gateway to deeper integration into global value chains, access to green finance, and attracting top talent, especially among Gen Z.

Under mounting pressure from the global business environment, many enterprises genuinely want to pursue an effective green transition. However, one of the biggest obstacles is the misconception that "greening" automatically means large investments and high costs. This fear of financial burden has left many companies particularly small and medium-sized enterprises hesitant to implement green transformation solutions.

1.2 Debunking the Myth: Green Transformation Doesn’t Always Start with Money — It Starts with Data

To overcome this barrier, businesses need a foundation that can accurately measure the costs and benefits of each initiative and that foundation is data.

Data-driven greening goes beyond simply applying new technologies. It is a strategic approach that transforms raw operational data into actionable insights, enabling companies to optimize processes, reduce waste, and enhance resource efficiency across the entire production chain. This approach harnesses the power of Big Data, Artificial Intelligence (AI), the Internet of Things (IoT), and Cloud Computing to deliver real-time monitoring, predictive analytics, and more informed decision-making.

Unlike traditional methods, which are often reactive and focus on managing pollution after it occurs, data empowers businesses to proactively prevent environmental risks and operate more intelligently. With the ability to offer high-resolution insights and predictive capabilities for both environmental and financial performance, data turns sustainability from a compliance burden into a true business strategy.

At the heart of this shift is a transformation in mindset: from viewing greening as a mandatory expense to embracing it as a smart investment strategy with clear ROI and short payback periods. Data allows companies to see the direct connection between environmental benefits such as waste reduction and resource efficiency and economic gains such as cost savings and profit increases. This creates a positive feedback loop, where sustainable initiatives are driven forward by tangible business value.

2. Data: The Key to Effective and Feasible Green Transformation

Using data as the starting point in a green transformation journey is not only a smart approach it is foundational and strategic, especially for manufacturing enterprises, where energy, raw materials, and waste continuously flow through production systems. Data serves as a detailed map, helping businesses understand “where they are” in terms of environmental impact so they can chart the most cost-effective and efficient path forward.

2.1 Leveraging Existing Resources and Optimizing Costs

One of the most powerful advantages of data is its ability to help businesses kickstart their green transformation without requiring massive upfront investment. By utilizing existing data such as energy and water consumption, raw material usage, or loss rates companies can tap into their current resources to uncover hidden opportunities for cost savings.

For example, by integrating IoT sensors into existing machinery, companies can monitor detailed operational indicators like electricity usage per device, pressure, temperature, or water flow in real time. These seemingly fragmented data points, once properly organized and analyzed using AI tools or performance analytics software, can reveal which parts of the system are underperforming, wasting resources, or consuming excessive energy.

Take this scenario: IoT sensors installed on current equipment track energy usage of individual machines, while AI-driven analysis identifies which areas are operating above acceptable thresholds. As a result, businesses don't need to overhaul the entire production line instead, they can upgrade only the inefficient components, adjust workflows, or reschedule operations to minimize waste using their existing infrastructure.

More importantly, data helps quantify hidden costs such as energy waste, excess raw materials, and inefficient operating time that are often difficult to identify using traditional management methods. This allows businesses to establish continuous monitoring systems, respond flexibly to operational changes, and gradually reduce fixed costs. And all of this can begin without external capital, simply by looking inward and making better use of existing resources.

2.2 Identifying Waste “Hotspots” and Reducing Investment Risks

Once businesses have built a comprehensive overview through analysis of existing data flows, the next step is to turn these insights into smart investment decisions.

At this stage, data is no longer just an operational monitoring tool it becomes a strategic map, providing objective evidence to help businesses identify key “hotspots” where targeted investment can deliver the greatest impact with the lowest risk. This approach helps avoid misguided, scattered, or intuition-based investments an especially critical advantage when resources are limited.

In fact, one of the most common reasons green transformation initiatives fail is due to poor investment targeting for example, replacing an entire production line when a simple upgrade to a specific stage could significantly reduce emissions.

With detailed data analyzed through AI-driven models, businesses can assess the performance of each process step, forecast the potential improvement from specific interventions, and pinpoint which bottlenecks are most worth addressing. This allows for a prioritized, evidence-based roadmap that maximizes returns while minimizing waste and risk.

Data also reinforces investment decisions by enabling early identification of pollution trends or environmental risks, allowing for timely preventive actions.

In the area of maintenance, data unlocks a new approach: predictive maintenance. Rather than following fixed periodic checks, AI can analyze signals from equipment to detect signs of wear or degradation, and recommend the optimal time for maintenance. A notable example is General Motors, which saved up to USD 20 million per year through predictive maintenance. Studies have shown that this approach can reduce maintenance costs by 25-30% and extend equipment uptime by 10–20%.

Beyond technical benefits, data also serves as a strategic compass to minimize investment missteps. By analyzing data flows related to market trends, consumer behavior, and input cost fluctuations, businesses can proactively adjust their production and supply plans to respond flexibly to change. This helps optimize inventory levels and improve readiness. For instance, Electrolux successfully reduced inventory by 25% and improved demand responsiveness by 10% through AI and data analytics integration into its supply chain.

2.3 Measurement, Transparent Reporting, and Compliance with International Standards

As the global economy shifts rapidly toward sustainable development, Environmental, Social, and Governance (ESG) reporting requirements are becoming increasingly stringent and urgent.

In particular, new regulatory frameworks such as the Carbon Border Adjustment Mechanism (CBAM) and the Corporate Sustainability Reporting Directive (CSRD) from the European Union are placing significant pressure on exporting enterprises. From 2025, companies will be required to submit accurate, independently verified emissions data, marking the end of reliance on estimated emission factors.

Optimizing Production with Artificial Intelligence (Source: Internet)

In this context, data plays a central role as a measurement tool, a reporting foundation, and concrete evidence of a company’s sustainability commitments. Businesses must go beyond collecting output data such as emissions and energy consumption. They need comprehensive data across the entire value chain from raw material sourcing, production processes, and logistics operations to the product lifecycle. This data must be detailed enough to reflect environmental performance at each stage and systematic enough to support real-time reporting.

Compliance with international standards such as the Global Reporting Initiative (GRI), the Sustainability Accounting Standards Board (SASB), and the Task Force on Climate-related Financial Disclosures (TCFD) is no longer just a competitive advantage it has become a passport for maintaining global competitiveness.

These standards require ESG data systems to meet three key criteria: transparency, traceability, and integration. This means businesses must make strategic investments in data infrastructure from sensors and data management software to skilled analytics teams to ensure that all information can be verified, audited, and reconciled by third parties.

As a result, data is no longer just an internal matter. It has become a critical asset that enables companies to overcome technical barriers, maintain export capacity, access green financing, and build credibility and trust with customers, investors, and strategic partners.

3. A Five-Step Process for Data-Driven Green Transformation

To effectively implement a green transformation strategy, businesses need to follow a structured process from data collection and analysis to action and continuous improvement. In this journey, data acts as the central catalyst, transforming raw information into knowledge that enables informed, transparent, and well-grounded decisions, both environmentally and financially.

3.1 Step 1: Analyze Environmental Impact and Collect Foundational Data

Every effective green strategy begins with a clear understanding of the current state. This initial assessment is not just a starting point it serves as the foundation for identifying priority areas for improvement, setting realistic goals, and designing impactful interventions.

To achieve this, companies must undertake comprehensive and systematic collection of operational data. Key categories of essential data include:

• Resource consumption data: Total energy consumption (kWh/MWh), share of renewable vs. non-renewable energy, energy intensity (per unit of output). This forms the basis for calculating energy, water, and material efficiency.
   
• Emissions data: Includes greenhouse gas (GHG) emissions under Scope 1 (direct operations), Scope 2 (purchased energy), and Scope 3 (upstream/downstream emissions from supply chain, logistics, product use, etc.).
   
• Waste data: Volume and type of solid and hazardous waste, wastewater generated, recycling rates, and treatment methods.
   
• Production operations data: Number of units produced, standard processes, machine uptime, material loss, defect rate, and equipment efficiency.
   
• Supply chain data: Information from suppliers about material origin, associated emissions, and partners’ environmental policies.
   
• Environment-related financial data: Energy costs, waste management expenses, green improvement investments, and return on energy-saving projects.
   
• Social and governance data (S and G in ESG): Workforce diversity, workplace safety, leadership involvement in sustainability, and internal ESG monitoring practices.
   

Data collection must be conducted cross-functionally across departments to prevent data silos a common barrier to successful green transformation.

Once the data is standardized and integrated, companies can begin to apply sustainability performance indicators (KPIs) as comprehensive measurement tools. These quantitative metrics are designed to reflect the environmental, social, and economic performance of business activities, providing a clear framework for setting targets and tracking progress over time.

The data collection process must ensure timeliness, reliability, and completeness. Data should be aggregated from the entire production process, and must also include information from suppliers and customers to create a truly comprehensive picture. If the data gathered at this stage is inaccurate or incomplete, it can lead to misidentifying key issues and inefficient resource allocation in subsequent steps.

When data is collected in a complete and real-time manner, businesses can build a digital twin a digital model that simulates the entire production process. This virtual replica enables companies to test improvements in a simulated environment before applying them in the real world, thereby minimizing risks, reducing the cost of experimentation, and uncovering hidden inefficiencies that would be difficult to detect through traditional methods.

3.2 Step 2: Analysis, Identifying “Hotspots” and Saving Opportunities

Data only becomes a true strategic asset when it is deeply analyzed and aligned with clear objectives. Following data collection, the analysis phase is crucial for transforming raw data into valuable insights helping businesses not only identify waste “hotspots”, but also understand root causes, forecast trends, and determine optimal actions.

Key data analytics techniques include:

• Descriptive Analytics: Aggregates and summarizes indicators such as energy, water, and raw material consumption to identify current hotspots of waste and emissions.
   
• Diagnostic Analytics: Digs deeper into the root causes of issues for example, uncovering why a specific machine consumes excessive energy or produces abnormal emissions.
   
• Predictive Analytics: Uses machine learning (ML) and artificial neural networks (ANNs) to forecast trends in energy consumption, production demand, or potential equipment failures. This enables companies to shift from reactive to proactive management.
   
• Prescriptive Analytics: Recommends optimal actions based on data to help achieve green goals, such as reducing resource consumption or lowering emissions.

DL-Based Energy Prediction Framework (Source: Internet)

However, businesses should not stop at observing and analyzing output indicators they must place these metrics within the context of a broader strategic framework. For instance, identifying that a particular machine consumes excessive energy is not enough. Companies need to understand why it is underperforming whether it’s due to production processes, operational conditions, or flaws in the original design.

Acting hastily based on isolated indicators such as reducing energy use in a single step can sometimes be counterproductive if it contradicts the company’s overall objectives. For example, if the goal is to reduce the carbon footprint across the entire value chain, an exclusive focus on improving unit-level production efficiency could obscure the broader impact on indirect emissions (Scope 2 & 3).

Therefore, before taking action, companies must ensure that data analysis is aligned with a clearly defined ESG strategy, select the right KPIs, and avoid “half-hearted” or misaligned improvements.

3.2 Step 3: Small Action - Big Impact 

Once key waste “hotspots” have been identified in line with strategic goals, the next step is to turn analysis into concrete action. However, this doesn’t mean settling for generic solutions like turning off machines or optimizing work schedules. In the context of global competition and increasingly strict sustainability demands, businesses must rethink what “small actions” really mean.

Small actions when evidence-based, systematically implemented, and scaled across teams or communities can create significant cumulative impact, both environmentally and economically. For example, in energy management, turning off unused equipment and unplugging devices during long breaks can save substantial electricity otherwise wasted in standby mode.

Maintaining air conditioners at a moderate temperature (not below 25°C) also reduces strain on cooling systems and conserves energy. Other effective solutions include improving insulation, switching to energy-efficient LED lighting, and investing in renewable energy sources all of which help reduce long-term energy consumption and operational costs.

In parallel, promoting the circular economy and waste reduction is essential. Applying the 5R principles (Refuse - Reduce - Reuse -Recycle - Rot) can greatly improve resource efficiency from rejecting unnecessary items and reusing bottles or fabric bags, to properly sorting recyclables and composting organic waste into green fertilizer.

Shifting toward sustainable consumption and transport further amplifies environmental impact. Companies can encourage local sourcing to reduce transport emissions and prioritize sustainable materials, such as natural fibers, in their products.

In logistics, data technologies can optimize delivery routes, enable the use of green vehicles (e.g., electric cars, bicycles), and promote alternatives like virtual meetings or rail transport to cut fossil fuel consumption.

Most importantly, data does more than just identify effective actions it quantifies the financial and environmental benefits of each choice. This transforms “green intuition” into a solid investment case. When decision-makers clearly see the return on investment (ROI), payback periods, and specific emission reductions, they are much more likely to prioritize and scale up sustainable actions.

Data Conversion Flowchart (Source: Internet)

In addition, instead of treating action as the endpoint, each measure no matter how small should be embedded into a continuous improvement loop, where outcomes are tracked, lessons are learned, and successes are scaled. This approach turns seemingly minor efforts into leverage points for building a sustainable operational culture, from frontline operations to executive strategy.

Ultimately, people are the cornerstone of any green transformation. Companies should move beyond a “command-and-comply” mindset and instead establish data-driven feedback loops that empower employees to contribute insights and suggest improvements based on real-world experience.

By promoting active participation through training, awareness-building, and empowerment, every individual can become part of the solution. From simple acts like turning off lights, conserving resources, or offering process improvements, each action contributes to cultivating a sustainability-driven culture a prerequisite for long-term and effective green transformation.

3.4 Step 4: Scaling Up Investment Through Data

Once businesses begin seeing tangible results from small actions, data becomes an indispensable decision-making tool for scaling up sustainable investments through technology.

Three key technologies Internet of Things (IoT), Big Data, and Artificial Intelligence (AI) no longer operate in isolation. Instead, they form an integrated, intelligent system that supports every step of the data value chain, from collection and processing to analysis and action.

IoT - The “Eyes and Ears” of Real-Time Data Collection
IoT comprises a network of connected sensors and devices embedded in physical environments and assets. These continuously monitor and collect real-time data on parameters such as temperature, humidity, energy usage, machine status, location, or even waste composition. IoT serves as the foundation of data infrastructure, delivering a steady stream of rich, real-time raw data to fuel subsequent analysis and decision-making.

Big Data - The “Brain” for Storing and Structuring Information
The vast and unstructured data generated by IoT devices cannot be effectively processed using traditional tools. This is where Big Data technologies step in. Big Data platforms are capable of storing, managing, and processing enormous volumes of data at high speed. By cleaning, organizing, and performing preliminary analysis, Big Data transforms raw streams into structured datasets, allowing for the detection of complex patterns and anomalies.

AI and Machine Learning – The “Intelligence” Behind Smart Decisions
Artificial Intelligence-particularly its branches like Machine Learning and Deep Learning-takes in processed data from Big Data systems. Using advanced algorithms, AI can analyze patterns, learn from past behavior, detect hidden risks, and generate forecasts. More importantly, AI can automate operational optimization and recommend specific actions based on its insights. AI's ability to transform raw data into clear, actionable intelligence is a key enabler for businesses to make fast, accurate, and sustainability-aligned decisions.

A powerful case study is CLP Power, a major electricity provider in Hong Kong that serves over 80% of the population. CLP deployed over 900,000 smart meters across households and businesses. The data collected enabled demand forecasting, real-time operational adjustment, and personalized recommendations for each customer reducing peak-hour loads and optimizing energy use without expanding physical infrastructure.

As a result, the peak demand response program attracted more than 950,000 participants, saving 410,000 kWh of electricity in just 4 hours equivalent to 160 tons of CO₂ emissions avoided. The program also helped optimize HVAC systems, achieving up to 30% energy savings in participating buildings.

The key point is this: no matter how advanced technology becomes, it still requires data to “lead the way.” Data is the essential factor that ensures green transition investments are not merely symbolic, but truly generate measurable economic and environmental value.

In short, technology serves as a powerful enabler to accelerate and enhance the effectiveness of the transition process, while data remains the foundational element throughout the entire lifecycle of technological application.

3.5 Step 5: Measure – Report – Repeat

After implementing data-driven green transformation solutions, the final and most critical step is to measure again to assess execution effectiveness, ensure transparency, and establish a continuous improvement cycle. At this stage, data is no longer just an input; it becomes a catalyst for next actions, forming the basis for businesses to make decisions that are accurate, timely, and responsible.

This re-measurement requires businesses to reassess all the key performance indicators (KPIs) initially set covering environmental, social, and economic dimensions through real-time connected dashboards. Data must be compared against the original baseline to quantify specific changes: how much CO₂ emissions have been reduced? How much energy, water, or cost has been saved? More importantly, post-implementation data helps reveal which behaviors, processes, or technologies truly generate value guiding future adjustments or scaling efforts.

Measurement alone is not enough without transparent reporting. ESG reporting today is no longer just about compliance; it is a trust-building tool for investors, customers, and partners. With the growing adoption of frameworks such as CSRD, GRI, and TCFD, businesses must present ESG data in a structured, credible, and comparable format as emphasized in section 2.3. The goal is clear: measure, report transparently, and align with international standards.

ESG Initiative Report - Overview Template (Source: Internet)

To meet the growing demands of ESG compliance, a variety of specialized software platforms have emerged to help businesses automate ESG reporting processes. For example, Arbor stands out with its ability to measure and visualize product-level carbon footprints. Microsoft Sustainability Manager integrates seamlessly with the broader Microsoft ecosystem to track and manage sustainability metrics, while Persefoni offers a comprehensive carbon accounting solution, covering Scope 1, 2, and 3 emissions.

These platforms can directly connect with enterprise resource planning (ERP) systems, IoT devices, and supplier data to ensure real-time, continuous updates of ESG information. Beyond executive-level insights, ESG dashboards have become valuable internal communication tools, helping employees across all levels understand how their daily actions whether energy-saving, emissions reduction, or operational optimization contribute to broader sustainability goals.

A critical aspect that cannot be overlooked is the integrity and reliability of data, especially during the reassessment phase. As greenwashing comes under tighter regulatory and reputational scrutiny, businesses must establish clear data verification mechanisms. Technologies such as blockchain can help build immutable ledgers, enabling full traceability especially crucial for Scope 3 emissions while AI assists in anomaly detection, validating data consistency, and flagging potential manipulation. ESG audits by third parties, both at limited and reasonable assurance levels, are increasingly becoming standard practice rather than optional exercises.

In short, the reassessment phase is not the end of the journey but the beginning of a new strategic loop. ESG data has evolved into a form of "strategic fuel", simultaneously measuring progress and enabling the next wave of actions. Companies that invest methodically in data-driven systems for measurement, reporting, and continuous improvement will gain a distinct edge in adaptability, learning capacity, and market trust. In a world where transparency and sustainability are becoming the norm, data no longer just helps companies “comply” it becomes a strategic asset for leadership.

4. Real-World Lessons from Industry Leaders

4.1 Uniqlo: A Data-Driven Green Transformation Strategy

Uniqlo, under the leadership of its parent company Fast Retailing, is implementing a comprehensive green transformation strategy that is both long-term and actionable. The company has laid out clear sustainability targets for 2030, aligned with its commitment to carbon neutrality by 2050 under the Paris Agreement.

Key targets include:

• A 90% reduction in greenhouse gas (GHG) emissions from its stores, and a 20% reduction across its entire supply chain (compared to 2019 levels).
• A 40% reduction in electricity consumption at its retail stores.
• Increasing the proportion of recycled materials to approximately 50%.
• Achieving a "zero waste" status through its 4R approach: Reduce, Replace, Reuse, and Recycle.
   

At the heart of this strategy is Project Ariake, an internal initiative launched in 2017, centered on the operational philosophy of “producing, shipping, and selling the right number of garments at the right time.” This demand-driven production model directly tackles the issue of overproduction a major source of emissions and waste in the fashion industry. Uniqlo adopts a proactive approach to reducing environmental risks at the source, rather than relying on expensive end-of-pipe solutions.

What enables this model is deep integration of data. Each year, Uniqlo collects more than 30 million data points to support weekly demand forecasting, enabling highly accurate production planning down to individual product units. This not only reduces inventory waste but also minimizes raw material usage from the outset. Additionally, the company leverages AI to analyze consumer preferences and trend forecasts, allowing it to fine-tune product offerings and reduce the likelihood of manufacturing items that won’t sell.

From a technical standpoint, Uniqlo focuses on optimizing existing infrastructure rather than engaging in costly, large-scale construction. For instance, the widespread installation of LED lighting across its stores in Japan achieved a 93.8% implementation rate, which contributed to a 38.7% reduction in greenhouse gas (GHG) emissions in 2020. This demonstrates the tangible impact of energy data monitoring to identify high-impact upgrade areas a more cost-effective and scalable strategy than major capital expenditures.

In addition, Uniqlo has innovated its production processes to minimize resource consumption. A notable example is its jeans finishing technology, which reduces water use by up to 99%, requiring only the equivalent of a single cup of tea per pair. This is a high-impact process innovation that does not require massive factory investment, proving that meaningful sustainability can be achieved through operational efficiency and smart upgrades.

In short, Uniqlo’s strategy illustrates that data is not just a supporting tool it is the central lever in its journey toward comprehensive emission reduction. From business model design to energy optimization and product circularity, every decision is anchored in deep data-driven insights. This approach not only enables Uniqlo to meet its sustainability goals but also demonstrates a pragmatic, scalable, and cost-effective green transformation a model worth emulating in the global fashion industry.

Green transformation isn’t just for big corporations, KHAAR, a Vietnamese startup participating in the Towards Zero Waste Accelerator co-hosted by BambuUP, is redefining sustainable fashion by creatively repurposing surplus materials. Leveraging CLO 3D simulation technology before physical production, KHAAR significantly reduces fabric waste and cuts prototyping costs. This digital-first, zero-waste design approach reflects how Vietnamese innovators are reshaping the fashion industry toward local sustainability with global relevance.

Explore how KHAAR and other Vietnamese businesses are making fashion greener, right here in Vietnam.

4.2 Heineken Vietnam: Data as Foundation, Sustainability as the Goal

At Heineken Vietnam, data is not merely a supporting tool it serves as the foundation guiding the company’s entire sustainability strategy, which is embodied in its bold commitment to “Brewing a Better Vietnam.”

The company has set ambitious targets: achieving net-zero emissions in production by 2030 and across its entire value chain by 2040; using 100% renewable energy; fully balancing water usage; and sending zero waste to landfill. Data is the key enabler that turns these commitments into effective, measurable action. Each target is backed by a rigorous system of data collection, analysis, and independent verification, and is aligned with the Science Based Targets initiative (SBTi) to ensure scientific credibility and feasibility.

Smart water management: data as a strategic lever

In the area of water management, Heineken Vietnam uses data as a core instrument to proactively control and optimize resource efficiency. Rather than merely tracking consumption, data enables the company to precisely quantify the volume of water that needs to be replenished in order to achieve “water balance.”

By applying the internationally recognized Volumetric Water Benefit Accounting (VWBA) framework, Heineken achieved water balance in the Tien River basin five years ahead of schedule, replenishing over 690 million liters of water annually an amount that exceeds the water used in its products and lost through evaporation during production.

In addition, the company’s real-time monitoring systems enable continuous optimization of operations. As a result, Heineken Vietnam maintains a water efficiency ratio of 2.65 hl water per hl of beer, significantly better than the industry average of 3.04. This is a compelling example of how data enables businesses to shift from reactive to proactive resource management, driving both environmental performance and operational excellence.

In the energy sector, Heineken Vietnam leverages data as a navigation tool in its transition to clean energy. A real-time energy monitoring system enables precise control over the efficiency of biomass and biogas fuel usage, helping the company achieve 99% renewable energy use in production (up from 96% in 2022) and a 93% reduction in CO₂ emissions compared to 2018.

Furthermore, Heineken Vietnam has partnered with Siemens to implement digital twin technology across 15 facilities. These virtual models simulate, analyze, and optimize thermal systems, resulting in 15–20% energy savings and a 50% reduction in CO₂ emissions. Beyond cutting consumption, data analytics also help identify energy leakage hotspots and enable timely corrective actions—maximizing returns on green investments.

Accurate data on material flows and recyclability forms the backbone of Heineken Vietnam’s zero-landfill waste goal, which the company has achieved since 2021. Rather than managing waste as an end-of-pipe issue, Heineken uses input data to design circular loops from the outset of production.

As a result, 99% of waste is recycled or reused: spent grain is repurposed as animal feed, surplus yeast becomes fertilizer, and wastewater treatment sludge is converted into clean soil. Even Tiger beer bottle caps are recycled into steel used to build bridges for local communities.

The company has also achieved impressive packaging recovery rates: 97% for glass bottles and 99% for beer crates. These figures highlight a highly efficient circular system, powered and optimized by robust data infrastructure.
