“Living our vocation to be protectors of God’s handiwork is essential to a life of virtue; it is not an optional or a secondary aspect of our Christian experience.”― Pope Francis, Laudato Si’
As a response to the Catholic Church’s long-standing regard for the care of God’s creation, Don Bosco School of Theology offers the Laudato Si’ Certified Environmental Trainer (LS-CET) program.
With Pope Francis’ Laudato Si’ as its guide, the program aims to promote the message of the encyclical to generate awareness and reflection and to train its participants in launching personal and community initiatives for the care of the Common Home.
The program examines the current ecological dilemma from the perspectives of Biblical and Moral Theology as well as science based studies in the environment. More importantly, the program offers practical hands-on training on how to use the technologies currently developed to regenerate Mother Earth.
The Laudato Si’ Certified Environmental Trainer (LS-CET) program aims to provide a holistic waste management education that integrates theology, ecology, and technology. In addition to these components, the school will incorporate community development into its curriculum. The community component will emphasize the importance of community involvement in waste management and the creation of sustainable regenerative systems.
The Theology Component will incorporate the teachings of the Catholic Church on environmental stewardship and the importance of caring for creation. Students will appreciate the moral foundations of integral ecology based in Scriptures and in other writings sacred to different religious traditions. The belief that the environment is a gift will provide the students with a deeper reason for their responsibility so that “what they received as a garden, cannot be left as a desert to the next generation.”
The Ecology Component will teach students about the interdependence of all living things and how human activity impacts the environment. In addition, the program will address the importance of scientific data in the proper evaluation of the ecological crisis. This will emphasize the need to work with the community to develop sustainable waste management systems. They will learn about the concept of “zero waste” and benefits of composting, recycling, waste reduction and residuals management, that involve the participation of every stakeholder.
The Technology Component will be a hands-on experience in using local innovations to create sustainable waste management systems for their households. Students will also learn the different technology-enabled food production, marine biodiversity, and sources of renewable energy applicable to their local contexts.
The Laudato Si’ Certified Environmental Trainer (LS-CET) program is an 80-hour program with 20 hours for the Theological and another 20 hours for the Ecological component and 40 hours for the Technological component.
The training course will run for eight (8) Saturdays from 8:00 AM – 5:00 PM. The program schedule is below:

Cosmogenesis and the Holy Spirit explores the intersection between cosmology and theology by examining the concept of cosmogenesis and its relationship with the Holy Spirit. Cosmogenesis is the study of the origins and development of the universe, while the Holy Spirit is the central concept in Christian theology manifesting the active presence of God in the world. By examining these two fields, students will gain a deeper understanding of the inter-connectedness between science and faith.
From Homogenesis to Christogenesis explores the intersections of ecology, anthropology, and Christology, with an emphasis on understanding the ways in which humans interact with their environment and the theological implications of these interactions. The course will examine the political, cultural, economic, and scientific facets of ecology from the perspectives of anthropology and Christology.
From an anthropological perspective, the course will explore the diversity of human cultures and their relationships to the natural world. It will examine how different cultural practices and beliefs shape human interactions with the environment, including subsistence practices, land-use patterns, and religious beliefs about nature. The course will also examine how environ-mental change and degradation affect different communities, particularly marginalized and vulnerable populations.
From a Christological perspective, the course will examine the theological implications of human interactions with the environment, particularly in light of the Christian tradition’s emphasis on stewardship and care for creation. It will explore how theological concepts such as creation, incarnation, and eschatology can inform and shape Christian responses to ecological challenges.

Liturgy and Creation aims to promote the importance of stewardship by understanding the significance of the elements of creation in the life of worship of the Church. This talk will discuss the different elements and their significance in the liturgical celebrations of the church, with particular consideration of the liturgical time, sacraments and sacramentals.
This course explores the intimate relationship between liturgy and creation, highlighting how the natural world is deeply woven into the Church’s liturgical life. It examines how elements such as water, fire, light, oil, bread, wine, and incense serve as sacred signs in the liturgy, revealing God’s presence and action in creation. The course also reflects on the theological, spiritual, and ecological implications of these symbols, encouraging a renewed appreciation of creation as a vital partner in worship and a call to ecological conversion.

Professor of Moral Theology and Socio-Pastoral Issues
Ethics of Ecology examines the relationship between morality and ecology. The course explores the ethical dimensions of environmental issues, such as climate change, pollution, and biodiversity loss, and evaluates how Christian moral theology can provide a framework for responding to these issues.
It begins by exploring the foundational concepts of Catholic moral theology that govern the relationship between God and the individual human being, the relationship of human beings with one another (social justice) and the often forgotten but equally important issue of man’s relationship with the natural, created world. Based on the principles of dialogue with contemporary history and the human and applied sciences, it will also explore the political, cultural, social and economic dimensions and underpinnings of environmental issues, including environmental justice, sustainability, and the rights of future generations. The course is ultimately designed to help both facilitator and learner to respond and commit oneself to an ethically sound, timely, personal, and collective stance of ecological conversion.
