About This Collection

The Ellen MacArthur Foundation is an independent charity with the aim of inspiring a generation to re-think, re-design & build a positive future through the vision of a circular economy. Ellen MacArthur founded the Foundation to better understand how on land too we rely on finite resources in the form of materials, energy and water after her experiences as a world class sailor having sailed over 26,000 miles to become the fastest person to circumnavigate the globe single-handed.

The Circular Economy 100 is a global platform bringing together leading companies, emerging innovators and regions to accelerate the transition to a circular economy over a 1000-day (3 year) period. The Annual Summit was held Wednesday 19 June 2013.

Circularity: a competitive edge in the era of tariffs?
April 13, 2026

Amid rising tariffs and supply chain disruption, Danielle Holly (Ellen MacArthur Foundation) and Tensie Whelan (NYU Stern) discuss circularity as a smart business strategy. Tensie introduces the ROSI (Return on Sustainability Investment) framework, developed at NYU Stern, which helps companies track and monetize sustainability's value, including efficiency, risk reduction, and new revenue. They explore how circular approaches shorten supply chains and mitigate geopolitical shocks.

The discussion also addresses why companies hesitate and what's needed to engage finance and governance. The Ellen MacArthur Foundation, an international charity, accelerates the transition to a circular economy to tackle climate change, biodiversity loss, and pollution.
