Chief Sustainability Officer (CSO) Network

“If we combine forces now, we can avert climate catastrophe. But, as today’s report makes clear, there is no time for delay and no room for excuses.” UN Secretary General António Guterres at the launch of the IPCC report, 9 August 2021.

Our network for Chief Sustainability Officers (CSOs) provides the opportunity for knowledge-sharing and learning within an exclusive community of CSO peers. Regular roundtable sessions led by experienced chairs, advisors and senior directors provide the opportunity to debate and discuss sustainability issues, leadership and strategy.

Annual membership is open to the Chief Sustainability Officers and sustainability leads of large and medium sized organisations globally. This is FREE thanks to a subsidy from a climate change foundation – sign up today!

A Winmark Guide to Choosing a Pledge to Achieve Change

The climate pledge market can appear confusing at first, as pledges vary widely in their level of commitment and the resulting action required to achieve them. A pledge is the beginning of a strategic change and it’s important that you choose or create the right one for your organisation.

Winmark’s Chief Sustainability Officer network has produced a detailed guide to the options available, designed for senior executives reviewing which climate pledges they should make.
