Our Commitment to Sustainability

Our commitment to sustainability is represented in our core values of Integrity, Commitment, and Innovation. We strive for environmental sustainability, social responsibility, responsible sourcing, business ethics and compliance, corporate citizenship, and employee volunteerism to have a sustainable operation and a long-term, positive impact on our stakeholders: investors, customers, employees, suppliers, and our communities.

We adopt a stakeholder-oriented approach to governance and are committed to conducting an ethical, lawful, profitable, and sustainable business that creates value over the long term. We are not actively or directly involved in any political advocacy or lobbying groups nor do we provide financial contributions to political organizations. Our engagements on these issues are mainly through industry associations that we support together with our industry peers, or through community engagement with non-profit organizations.

Through our extensive sales and distribution network we provide customers around the globe with a broad portfolio of innovative, energy-efficient, and eco-friendly products. It is our firm belief that our stakeholders’ well-being is supported by sustainability considerations and such considerations are integral to our ongoing organizational success and operational resilience.

Stakeholder Engagement

Our decision to support sustainability influences our company operations worldwide: responsible manufacturing, the health & safety of employees, local compliance, quality standards, human resource and human capital management, research and development, product innovation, supply chain management, business ethics, investor relations, and corporate citizenship. We engage with our stakeholders, specifically employees, customers and investors, for feedback on our sustainability efforts.

We view sustainability as a competitive advantage and have adopted a sustainability-oriented approach to assess and address related risks that may influence our operational activities, business results, and financial performance. This includes considering the importance of economic, environmental, and social factors as they impact our business and stakeholders. By engaging with stakeholders to identify sector- and company-specific risks and opportunities, we may develop proactive strategies to uphold our sustainability standards. We also assess our progress and leverage industry-standard certification and audit processes to ensure sustained accountability and long-term performance.

We are privileged to partner with our customers in building sustainable products and applications that contribute to the health and well-being of our communities and our planet.

Code of Conduct

We align our business practices and operations with the Code of Conduct published by the Responsible Business Alliance (RBA), a leading industry coalition dedicated to corporate social responsibility in global supply chains. Diodes' CSER Code of Supplier Conduct and Human Rights and Workforce Labor Rights Policy are based on the RBA Code of Conduct. The RBA Code of Conduct establishes standards to ensure safe working conditions in the electronics industry and in industries in which electronics is a key component, including the supply chains that support those industries. The RBA Code of Conduct seeks to ensure workers are treated with respect and dignity, and that business operations are environmentally responsible and ethically conducted. The RBA Code of Conduct is in alignment with the UN Guiding Principles on Business and Human Rights and is based on international principles and norms that we support and incorporate in our business practices, including the United Nations (UN) Universal Declaration of Human Rights, the International Labor Organization’s (ILO) International Labor Standards and Declaration on Fundamental Principles and Rights at Work, the OECD Guidelines for Multinational Enterprises, and ISO standards.

Through its rigorous RBA Validated Assessment Program (VAP), Diodes endeavors to ensure that its operational activities are consistently conducted in alignment with the RBA Code of Conduct and Diodes’ quality standards and procedures.

We recognize the role we play in society and are committed to maintaining a sustainable and successful business over the long term by taking a stakeholder-oriented approach.

We are dedicated to creating and maintaining long-term value for our stakeholders and we engage in activities that will lead to sustainability and shared prosperity for our business and our communities.

  • Fostering a corporate culture of trust, diversity, and inclusion where everyone is treated with dignity and respect, and diverse perspectives are valued;

Governance and Oversight

Sustainability is a strategic focus for the Diodes management team and the Diodes Board of Directors (Board). To further accelerate our commitment to sustainability, and with the support of the Board, we created a Steering Committee to focus on sustainability and the ongoing assessment of our operations and their impact on the communities in which we operate. 

The sustainability Steering Committee is headed by our Senior Vice President of Operations and is comprised of representatives from multiple functions including corporate governance, regional management, operations management, legal and compliance, human resources, and quality. The Steering Committee approves sustainability-related policies, long-term objectives, and external disclosures and reporting. The Steering Committee also has operational control of environmental, health and safety, and social risks, and provides guidance on actions needed to address these risks.

Given our global manufacturing footprint and strong commitment to environmental responsibility, we also formed a Task Force represented by regional environmental, health, and safety (EHS) subject matter experts. This Task Force is supported by the General Counsel and Corporate Compliance Officer to focus on harmonizing our EHS metrics and leveraging best practices. Both the Task Force and the Steering Committee conduct regular review meetings to assess performance and drive continuous improvement.

The Task Force works closely with the Steering Committee, which provides periodic updates to the Board and engages frequently with the CEO and Lead Director on sustainability issues. With oversight and support from the Board, we have developed and implemented business strategies, and managed business operations in ways that are resilient to sustainability-related risks, including the impacts of climate change and pandemics.

In addition to the Board’s increased oversight of sustainability efforts, the executive bonus compensation includes a measurable sustainability component to further demonstrate and enhance the management’s commitment to sustainability.

We also engage in regular dialogue with stakeholders and sustainability rating agencies to solicit feedback as we continue to sharpen our focus on sustainability. Taking into account sustainability standards that are appropriate for the semiconductor industry, and for companies with a manufacturing footprint and scale of operations that are comparable to ours, specific sustainability performance metrics are identified where appropriate as we strive for continuous improvement. We believe these collective sustainability efforts help us create and maintain long-term profitability for our shareholders.

Responsible Disclosures

As part of responsible reporting to our stakeholders, and specifically institutional investors, we are committed to providing information that reflects the Seven Principles for Effective Disclosures published by the Task Force on Climate-Related Financial Disclosures (TCFD). 

We also refer to the TCFD voluntary framework around these thematic areas of corporate activities—governance, strategy, risk management, and metrics and targets. We support the industry-specific metrics recommended by the Sustainability Accounting Standards Board (SASB) for the Technology and Communications Sector specific for the semiconductor industry, and use them as guidance in our development of disclosures. 

We focus our disclosures on the key sustainability issues identified by SASB Materiality Map®and will continue to update these to provide material and relevant information to our stakeholders.

We actively work to make our sustainability disclosures more comprehensive, accurate, and transparent. The information disclosed is based on internally available data and the management’s good faith estimates, approximations, and analysis. The information has not been independently audited or verified by third parties. Past performance is not an indication of our future performance or results. Our performance, the measurement of our performance, and any assumption used in measuring our performance on these environmental and social factors, will continue to evolve over time. We value feedback from our stakeholders and we can be reached at compliance@diodes.com.

We strive to align our disclosures with the framework provided by the Sustainability Accounting Standards Board (SASB) for the Technology and Communications Sector specific to the semiconductor industry (“SASB Framework”). Please click here for a mapping of how our latest disclosures align with the SASB Framework.

As we continue to collate information required under the SASB Framework for the various accounting metrics, we will publish additional disclosures as part of our efforts to provide transparency and accountability to our stakeholders.
