For the second consecutive year, Zoetis has received the 2024 World’s Most Ethical Companies® recognition by Ethisphere, a global leader in defining and advancing the standards of ethical business practices. Zoetis is one of only four pharmaceutical companies to make the list, and the only animal health company to be recognized. In 2024, 136 honorees were recognized spanning 20 countries and 44 industries. 

“It’s a privilege to be recognized by Ethisphere as one of the World’s Most Ethical Companies,” said Jeff Williams, Chief Compliance Officer at Zoetis. “Zoetis is deeply committed to maintaining the highest standards of ethical business conduct. I am grateful to our colleagues whose unwavering commitment to integrity is the cornerstone of our purpose to nurture the world and humankind by advancing animal care.” 

Methodology & Scoring

The World's Most Ethical Companies assessment is grounded in Ethisphere's proprietary Ethics Quotient®, an extensive questionnaire that requires companies to provide over 240 different proof points on their culture of ethics; environmental, social, and governance (ESG) practices; ethics and compliance program; diversity, equity, & inclusion; and initiatives that support a strong value chain. That data undergoes further qualitative analysis by our panel of experts who spend thousands of hours vetting and evaluating each year's group of applicants. This process serves as an operating framework to capture and codify truly best-in-class ethics and compliance practices from organizations across industries and from around the world.
