Engaging Seminaries Project

This project encourages Spiritual divinity and theological schools and seminaries to integrate lessons on faith and ecology. As part of the project, ICSD has published multiple reports on faith and ecology courses being offered by seminaries around the world, and created the world's largest online syllabus collection of such courses.
ICSD also organizes conferences for seminary deans, faculty, and others on religion and ecology. They help equip seminaries to prepare the next generation of religious leaders to engage in Creation care and environmental justice. They have co-organized six conferences so far: The Southeast Symposium on Ecologically Informed Theological Education in Atlanta in March 2018, The Midwest Symposium on Ecologically Informed Theological Education in 2017, the Washington D.C.
