The urgency of addressing climate change and biodiversity loss has brought the Sustainable Development Goals (SDGs), particularly SDG 13 (Climate Action) and SDG 15 (Life on Land), to the center of global discourse. This paper examines how biblical theology can inform and strengthen global environmental ethics by drawing from scriptural insights on stewardship, justice, and the integrity of creation. Anchored in passages such as Genesis 2:15, Psalm 24:1, and Romans 8:19–22, the study establishes theological foundations that resonate with the moral imperatives of the SDGs. Using a mixed-methods approach that integrates biblical exegesis, theological reflection, and empirical data from Christian communities in Nigeria, the findings reveal that biblical values of stewardship and justice align closely with global environmental objectives. The study concludes that Christian theology offers a robust ethical framework that can enrich environmental governance, climate advocacy, and sustainable practices.
