The Environmental Stewardship Committee at STM was created in 2008. It was changed in 2024 to the "Laudato Si' Action Plan - On Care for Our Common Home Committee”. This reflects a broader scope as outlined by the Dicastery for Integral Human Development in 2019 to “implement” the many ideas from Pope Francis’ encyclical Laudato Si' (Praised Be to You) 2015. The encyclical dealt with Caring for Our Common Home and was followed in 2023 by his exhortation Laudate Deum (Praise God).
