Thought Leadership

What experts in the field are saying about corporate sustainability.
“When government lacks capacity to deal with big problems, corporations have to step in, despite it being outside the traditional bounds of business. And large companies that already have experience with climate resiliency are well positioned to support cities with these challenges.”
– Niel Golightly, VP, Shell Oil Company (2018)

“Too much ground is lost because of confrontation between civil society and business. For corporates to be part of the solution, and they need to be, civil society has to see them not just as the enemy.”

Robert Barrington, Executive Director, Transparency International (2018)

“The fight against antimicrobial resistance will take decades, and the life sciences industry is committed for the long haul. However, the full impact of industry’s efforts can only be made through collaboration with governments and providers, and other public health stakeholders.”

– Thomas Cueni, Chair, AMR Industry Alliance (2018)
