The Halki Summit is a gathering of activists, scientists, journalists, business leaders, theologians, and academics engaging and working across intellectual boundaries to bring the global environmental discussion to a new and richer place. At the heart of that discussion is the belief that no effort can be successful without a fundamental change in values as manifested in ethics, spirituality, and religion.

Halki Summit I, which focused on the theme of “Global Responsibility and Environmental Sustainability,” was held in June 2012, featuring such prominent speakers as Jane Goodall, Bill McKibben, James Hansen, and Amory Lovins.

Halki Summit II brought together pioneers and experts from around the world on the theme: “Theology, Ecology, and the Word: a conversation on the environment, literature and the arts.” The second Halki Summit took place from June 8-10, 2015, and included such prominent speakers as Terry Tempest Williams, Terry Eagleton, Timothy Gorringe, Raj Patel, and James Balog.

Halki Summit III brought together scholars and students from theological schools and seminaries all over the world for a discussion of “Theological Formation and Ecological Awareness” in Istanbul, Turkey (June 1-3, 2019), with such distinguished speakers as Metropolitan John of Pergamon, Celia Deane-Drummond, Elizabeth Theokritoff, Barbara Rossing, and Fred Bahnson.
