On Saturday, July 13th, ACES will welcome environmentalist, entrepreneur, activist, and author Paul Hawken, who will present on how humans can halt climate change — the most important challenge facing our planet. Hawken’s latest best-selling book, “Drawdown: The Most Comprehensive Plan Ever Proposed to Reverse Global Warming,” outlines 100 tangible solutions to address climate change, each backed by peer-reviewed studies and an extensive team of researchers.

Hawken is one of the environmental movement’s leading voices, and a pioneering architect of corporate reform with respect to ecological practices. His work includes founding successful, ecologically conscious businesses, writing about the impacts of commerce on living systems, and consulting with heads of state and CEOs on economic development, industrial ecology, and environmental policy. Hawken is Founder of Project Drawdown, a non-profit dedicated to researching when and how global warming can be reversed and multiple sustainability-focused companies. His book, “Natural Capitalism: Creating the Next Industrial Revolution,” co-authored with Amory Lovins, has been read and referred to by several heads of state including President Bill Clinton who called it one of the five most important books in the world during his tenure as President.

Hawken will deliver the keynote address at ACES’ sold-out 50th anniversary celebration, An Evening on the Lake, on Thursday, July 11th. On Saturday, July 13th, Hawken will present a public Hurst Lecture Series talk at 6PM in partnership with The Aspen Institute at Paepcke Auditorium. Tickets are $25 per person and on sale via aspenshowtix.com or in-person at the Wheeler Opera House box office in Aspen.
