The Corporate Sustainability Assessment at a glance

The S&P Global Corporate Sustainability Assessment (CSA) is an annual evaluation of companies’ sustainability practices. It covers over 10,000 companies from around the world. The CSA focuses on sustainability criteria that are both industry-specific and financially material and has been doing so since 1999.



  • Riva Krut, VP and Chief Sustainability Officer, Linde PLC
    "We consider the CSA to be the premier external sustainability assessment. To keep our sustainability strategy relevant into the future, Linde can’t simply look into the mirror. We need a way to be able to look into the future. The CSA is one of our key tools to do that"
