A global network of organisations
You're not the first to face these challenges
Every organisation's sustainability challenges feel unique. They rarely are. Our members identify the problems affecting the entire industry, then solve them together. The standards, frameworks, and strategies below exist because a member brought us a problem
“Our commitment to becoming sustainable by design across our entire portfolio creates a dynamic ecosystem where challenges can be brought back to GSF to shape standards, while simultaneously allowing us to adopt and apply those standards to address real-world challenges for our customers”
Gadhu Sundaram
Chair, GSF; VP of Application Services, NTT DATA
