Climate Change Management

The World Economic Forum (WEF) recently released “Global Risks Report 2023”, which indicates that the cost of living will dominate global risks in the short term. The energy crisis, food shortages, and inflation resulting from the war in Russia-Ukraine and the Covid-19 pandemic have become urgent global issues. Climate change continues to be the biggest long-term risk. Greenhouse gas emissions produced by humans since the dawn of the industrial revolution and capitalism have led to global warming. The high costs resulting from extreme weather events have increased the awareness of governments, international organizations, and civil society throughout the world. Industries are confronting pressure from economic stagnation, the challenges of energy transformation, and the risk of geopolitical instability at the same time they have to face up to the urgent and worsening climate issues that have been accumulating for over a century. This is not an easy task, but it is only through being more proactive in combating climate change and increasing the resilience of our Company that we can move towards sustainability.

As a provider of electronic technology, Winbond is deeply aware that our actions affect the global economy, and in fact function as a key factor in shaping the landscape of society. To comply with international standards and domestic policies related to environmental sustainability, we adopted the framework of the Financial Stability Board’s (FSB) Task Force on Climate-Related Financial Disclosures (TCFD) and published Winbond’s first TCFD report in 2022, which was the company’s 35th anniversary. Through this report, we hope to convey our social commitment to our stakeholders.

Climate Risk Management

Climate Risk Management

Risk Management Framework

Winbond is a manufacturer of semi-conductors. Natural disasters, accidents, man-made disasters, changes in the international political and economic situation, the introduction of new technologies by competitors, and changes in policies and regulations can potentially result in severe impacts on operations and finance. In light of this fact, Winbond established the Risk Management Committee under the Board of Directors to implement risk management through the Committee’s subdivisions or responsible units in accordance with their scope of operations. Aside from formulating a sound set of internal regulations and operating procedures, the Committee is also responsible for developing comprehensive plans and procedures for preliminary assessments, hedging, and loss prevention and crisis management, and regularly reporting to its oversight and governing bodies.

Risk Identification

Identify significant risk items, assessment methods, and risk appetite for the annual operational plans and goals of each unit, and obtain approval from the supervisor for the annual budget.

Risk Analysis

Calculate the risk value for identified significant risks, and in addition to the annual estimation, conduct quarterly revisions of the risk value. Any significant changes should be reported in the quarterly reports.

Risk Assessment

Each unit assesses significant risk items according to the appropriate operational frequency and compares them with the approved risk appetite, reporting to the management unit as needed.

Risk Response

When the actual situation exceeds the approved risk appetite, each unit immediately proposes risk response recommendations. Upon approval, the appropriate responses are implemented in accordance with risk management policies, procedures, and hierarchical responsibility criteria.

Supervision and Review

Risk management-related requirements are incorporated into the audit system in accordance with risk management policies and procedures for tracking, enabling the establishment of control points, self-assessment, and audit verification operations.

Winbond has incorporated climate change risks into its long-term operations management. To understand the impacts of climate change risks on the environment and operations, Winbond has introduced the TCFD, conducts annual evaluations, discloses climate risks and opportunities as well as their financial impacts (both qualitative and quantitative), and proposes review and management strategies based on international regulatory trends and market development observations since 2021. Winbond will continue to monitor risks and impacts resulting from climate change, strengthen its operational capabilities, promote carbon reduction projects, increase energy efficiency, and firmly step towards sustainable development.

Procedures for Identifying Climate Change Risks and Opportunities

In 2022, Winbond established the TCFD with 40-plus members, over 60% of whom are at the department executive level. Members are divided into teams according to the nature of their job. Each team discusses climate change issues with relevance to their area of operations. Over the course of four workshops and educational training, the TCFD has identified four major climate risks and seven minor climate risks, as well as five major climate opportunities and four minor climate opportunities.
