This chapter explores the convergence of environmental theology and climate justice in Pope Francis’ encyclical Laudato Si’. Amidst the multifaceted challenges posed by climate change, I delve into the critique of the ‘Anthropocene’ concept while highlighting the significance of liberation ecology in shaping Christian perspectives and actions toward environmental stewardship. By analyzing key principles and insights from Laudato Si’, this chapter contends that liberation ecology not only imposes a moral imperative but also embodies a profound Christian commitment to denouncing structural injustices that disproportionately affect marginalized communities worldwide. Through this lens, I elucidate how liberation ecology can catalyze environmentally conscious initiatives and the redressal of environmental inequalities. In contributing to the ongoing discourse on the ethical underpinnings of environmentalism, this chapter aims to foster a deeper understanding of the interplay between faith, justice, and environmental responsibility, urging for a holistic approach that acknowledges the interconnectedness of ecological and social concerns.
