The text summarizes work of the thematic group on Economic and Ecological Justice and Sustainable Future of the Conference of European Churches. The group consists of theologians, experts in ecological and political science, as well as activists from churches across the continent. Caring for God’s creation is an integral part of the calling of the churches. In this publication the Conference of European Churches is asking how this can be done? The book offers a summary of studies and discussions among theologians from churches of different confessional families. A first theological section underlies key aspects of several theological traditions. In a second section, we learn about the European Green Deal aiming to transform the EU into a modern, resource-efficient, and competitive economy with no net greenhouse gases emissions by 2050. The text supports the main aim of the Green Deal, however, raises concerns related to some of its principal parts.
