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
In a world of rising tariffs and supply chain disruption, could circularity be one of the smartest business moves a company can make? Danielle Holly, the Ellen MacArthur Foundation’s North America Lead, is joined by Tensie Whelan, founder of the Center for Sustainable Business at NYU Stern and former President of the Rainforest Alliance, to explore this and more. Tensie explains the ROSI (Return on Sustainability Investment) framework, developed at NYU Stern to help companies track and monetise the full value of sustainability strategies. This includes operational efficiency, risk reduction, new revenue and customer loyalty. Together, they explore how circular approaches can shorten supply chains and reduce exposure to tariffs and geopolitical shocks. They also tackle the harder questions: why do most companies still not act, even when the numbers stack up? And what will it take to bring finance, governance and the boardroom along for the journey?
