Founded in 1897 in the Swiss Alps, today, Lonza operates across five continents. With approximately 15,000 employees, we comprise high-performing teams and individual talent that make a meaningful difference to our own business, as well as to the communities in which we operate. Our business benefits from global supply chains, but we have worked to maintain the agility to address marketplace needs on a local level.
A firm commitment to responsible business and sustainability underpins everything we do. Minimizing our impact on the environment, conserving energy and natural resources, and helping to improve life quality are all central to our culture. Lonza's Vision Zero initiative is a prime example, as we strive to achieve zero workplace accidents and injuries, zero environmental incidents, zero product transportation incidents and zero manufacturing process incidents. We work to attract and retain the best talent, to make a meaningful difference to our own business, as well as the communities in which we operate.
