*General Studies-3; Topic: Conservation, environmental pollution and degradation, environmental impact assessment.*

Introduction

• The recent advisory opinion by the International Court of Justice (ICJ), declaring that countries are legally liable for greenhouse gas emissions under international law, marks a turning point in global climate governance.

• Though not legally binding, the ruling offers authoritative legal clarity and boosts the case for equitable climate justice, particularly for vulnerable and developing nations.

Background

• Climate change as a legal question: For decades, climate change has been treated primarily as a scientific, economic, and political challenge. However, recent efforts have shifted the discourse towards climate change as a matter of legal responsibility.

• UN General Assembly’s request: In 2023, the UNGA formally requested the ICJ to issue an advisory opinion on countries’ legal obligations related to climate change, following a campaign led by Vanuatu, a Pacific island nation acutely vulnerable to sea-level rise.

Reinforcement from Other International Rulings

The ICJ ruling does not exist in isolation. It is reinforced by precedents from other legal bodies:

Conclusion

• The ICJ’s declaration marks a historic moment in the legal battle against climate change. While advisory, it elevates climate inaction to a legal wrongdoing and recognizes climate justice as a right for all, especially the most vulnerable.

• The challenge lies in translating this legal momentum into actionable policies, binding treaties, and equitable outcomes on the ground.
