Stakeholder expectations and the business environment in which we operate constantly evolve. Our Priority Topics Assessment (PTA) process helps us identify and prioritize the environmental, social and governance topics that matter most to our stakeholders and to our Company. The results inform and shape our sustainability priorities, public goal setting and reporting.
We have been conducting PTAs every two to three years since 2008, with our most recent and most robust assessment conducted in 2019. A detailed description of the 2019 PTA process, methodology and definitions of topics be can be found here.
