TSMC Leads The Industry as the Only Semiconductor Company Chosen for the Dow Jones Sustainability Indices (DJSI) for 20 Consecutive Years
Grounded in its mission to build a lasting foundation, TSMC is steadfastly committed to its business principles and four core values of Integrity, Commitment, Innovation, and Customer Trust. By adhering to its core business, TSMC focuses on its core competencies and primary business while actively carrying out the United Nations’ Sustainable Development Goals (SDGs).
TSMC is one of the best Asian companies in sustainability practices. The Company continues to push the envelope of technology and improves power efficiency of its products, and communicates with stakeholders in compliance with international practices. These efforts are reflected in the Company's robust ROC, which underpins its outperformed share price. We look forward to seeing greater success from TSMC in coming years.
Economic Achievement— Sustained Economic Value Is the Foundation of Corporate Social Responsibility
TSMC dedicates itself to corporate governance, and strives for the greatest achievements in its core business. In 2019, despite ongoing intense competition from both established players and relatively new entrants to the business, TSMC maintained its leading position in the foundry segment of the global semiconductor industry with an estimated market share of 52%, while revenues reached a record high for the 10th consecutive year, firmly solidifying its position as the largest dedicated semiconductor foundry in the world.

Environmental Performance— Green Manufacturing Implementation Facilitates Mutual Prosperity Between Technology Development and Environment
As a practitioner of green manufacturing, TSMC has committed NT$ 19.66 billion toward environmental protection and successfully implemented 763 innovative programs in energy conservation, water conservation, and waste reduction in 2019. Our overseas facilities have once again achieved zero emissions. In addition, TSMC became the first semiconductor company to join RE100, and receive platinum certification by the Alliance for Water Stewardship (AWS).

Social Dimension— TSMC Builds an Innovative and Inclusive Workplace and Shines Light in Society’s Dark Corners
TSMC deeply instills a people-oriented company culture, building a friendly workplace that meets and exceeds domestic and international health and safety standards and other and is in compliance with the human rights regulations. The Company aims to be an employer that all employees can be truly proud of. In addition, “TSMC Culture and Education Foundation” and “TSMC Charity Foundation” serve as focal points for funds, materials, and people from inside and outside the Company to drive the development of society with kindness.

With each and every TSMC employee steadfast at his/her role, we believe that positive changes will occur continuously.
Though the future is filled with challenges, TSMC will always stay true to its cornerstones ‒ Integrity, and Responsible Operations. Our CSR achievements in 2019 were the results of a long-term effort of each TSMC employee. Bearing a dedication to "diligently doing everything right,” we will continuously move forward to pursue the mutual good.
