QTC AND
Sustainability
We believe that doing good work with quality and responsibility
builds satisfaction for all stakeholders and strengthens sustainable growth.
30 Years of QTC Energy
Creating Sustainable Value for the World and Future Generations
QTC believes that sustainability is not merely a goal, but a fundamental principle embedded in the way we conduct business, enabling long-term value creation for the Company, its stakeholders, society, and the environment.
We have established a Sustainability Management Framework that integrates our core corporate value, “Quality of Details,” into our strategy and operations across all dimensions. At the core of this framework lies our guiding principle:
Q + R = S (Quality + Responsibility = Sustainability)
which underpins our strategic direction and decision-making processes.
QTC believes that uncompromising quality, combined with strong responsibility toward all stakeholders, forms the foundation of business resilience and sustainable long-term growth. This approach enables the Company to deliver positive impacts across all ESG dimensions— environmental stewardship, social responsibility, sound governance, and long-term economic performance.
Beyond governance structures and management systems, QTC’s sustainability framework represents a shared mindset and organizational culture. It reinforces the belief that doing the right thing, with quality and accountability, creates enduring value for both the Company and society.
As QTC enters its fourth decade, we remain committed to balanced and responsible growth—advancing alongside communities and the environment, while delivering sustainable returns and building a better future for generations to come.
CHAIRMAN’S MESSAGE
“Throughout the years, QTC has consistently demonstrated its unwavering commitment and determination to develop the organization toward stable growth, while simultaneously creating shared value with society and the environment. This includes efforts to reduce greenhouse gas emissions in business processes, promote the use of renewable energy, manage resources efficiently, enhance labor potential and quality of life, ensure transparent and ethical corporate governance, and continuously support communities surrounding the factory. Moreover, QTC is dedicated to investing in clean energy businesses to foster stable and sustainable growth that is environmentally friendly.
“From its inception, QTC was founded with the intention of becoming a high-quality transformer manufacturer to meet the needs of Thailand’s energy industry. The company began as a small factory in Rayong Province and gradually grew into a nationally recognized organization specializing in clean energy technology and comprehensive energy solutions.
For over 30 years, QTC has adhered to the principle of “Quality + Responsibility = Sustainability,” which serves as the core of its sustainable development. This principle emphasizes environmental stewardship, social responsibility, and good governance alongside business growth.
We drive our business through innovation and a new generation of talent, developing technologies and services such as the Super Low Loss energy-saving transformer that helps reduce greenhouse gas emissions, and the Smart Transformer Monitoring System. We also invest in clean energy businesses while cultivating a corporate culture focused on sustainability, diversity, and human potential development. This is achieved through the nurturing of ‘good people’ and ‘capable people’ by instilling Green Culture and Safety Culture.
Looking ahead, QTC remains committed to creating energy solutions aligned with the circular economy, clean energy, and responsibility toward people and the planet — striving to become ‘Energy for a Sustainable Future’.”

This principle refers to management practices that emphasize the creation of quality and responsibility, achieving a balanced approach across three key dimensions: environmental, social, and governance and economic dimensions. These practices are aligned with the relevant United Nations Sustainable Development Goals (SDGs) applicable to the Company’s business operations.

QTC & Sustainability
QTC Energy Public Company Limited has established the QTC Sustainability Framework as a policy framework and strategic mechanism for integrating business operations with responsibilities toward stakeholders, society, and the environment, within the operational context of the Company and its subsidiaries, with the corporate value of Quality of Details serving as a key foundation for driving sustainable growth. The sustainability framework is based on the sustainability equation Q + R = S (Quality + Responsibility = Sustainability), which reflects the Company’s strategic approach to creating long-term value through quality operations together with responsibility across all dimensions of the value chain, in order to strengthen competitiveness, stakeholder confidence, and the long-term sustainability of the organization.

Stakeholders of “QTC”
QTC Energy Public Company Limited places strong emphasis on stakeholder management as a key element of sustainable business operations. The Company aims to achieve growth while upholding responsibility toward all stakeholder groups throughout the value chain, under the sustainable development framework covering economic, social, environmental, and governance dimensions.
The Company systematically identifies, analyzes, and prioritizes its stakeholders by classifying them into primary and secondary stakeholder groups. This approach enables the Company to define appropriate engagement methods and responses to the expectations and concerns of each group, in alignment with the business context and the Company’s enterprise risk management framework.
The Company’s primary stakeholders include employees, executives, shareholders, customers, business partners, and suppliers, who are directly involved in and impacted by the Company’s business operations. Secondary stakeholders, such as communities, government agencies, and society at large, play an important role in supporting and fostering an environment conducive to the Company’s long-term operations and growth.
The Company promotes stakeholder engagement through various channels, including internal communications, shareholders’ meetings, engagements with customers and business partners, community consultations, as well as grievance and feedback mechanisms. Information and feedback obtained are incorporated into the consideration of material sustainability issues, strategic planning, and the continuous improvement of the Company’s operations.
With a strong commitment to conducting business in accordance with good corporate governance principles, the Company upholds transparency, fairness, and social responsibility in order to create shared value and strengthen trust among all stakeholder groups, thereby supporting stable and sustainable long-term growth.
Material Topics
Double Materiality Assessment is a strategic approach used to identify sustainability issues that are significant both in terms of their impact on society and the environment (inside-out), and their financial implications for the organization (outside-in). This dual perspective enables companies to evaluate how their operations affect external stakeholders, while also understanding how external sustainability challenges—such as climate change or resource scarcity—could influence business performance. The process involves stakeholder mapping, ESG topic identification, risk and opportunity analysis, and prioritization of material issues for disclosure. Ultimately, it supports transparent reporting and informed decision-making for long-term resilience.

Strategies for Sustainable Development
Through the Double Materiality Assessment approach, the company has identified key sustainability issues by evaluating both the impact the organization has on the environment and society (Inside-Out), and the financial implications of external sustainability factors on the organization (Outside-In). This assessment has led to the development of core sustainability strategies aligned with the company’s vision to become “World Class” and its culture of precision, “Quality of Details.” These strategies comprehensively address Environmental, Social, and Governance (ESG) dimensions through risk management, stakeholder engagement, and the establishment of measurable performance indicators. The strategies are cascaded across all levels of management and employees to foster shared understanding and active participation in driving sustainability goals forward—under QTC’s sustainability equation:
“Quality + Responsibility = Sustainability.”
