ICJ Advisory Opinion on Climate Action

GS3 – Environment

Context

The International Court of Justice (ICJ) has issued a landmark advisory opinion defining the legal responsibilities of states in addressing climate change, moving global climate action into the realm of international law.

Background of the Case
  • Origin: Initiated by South Pacific law students in 2019, the campaign called for legal accountability for climate inaction.
  • Vanuatu’s Role: Vanuatu spearheaded diplomatic efforts to highlight climate impacts on vulnerable island nations as violations of international law.
  • UNGA Involvement: The United Nations General Assembly (UNGA) referred the matter to the ICJ, seeking clarification on states’ legal obligations related to climate mitigation and liability for non-compliance.
Takeaways from the ICJ Advisory Opinion
  • Legal Accountability:
    • States have a binding legal duty to prevent and reduce serious climate-related harm.
    • Failure to act constitutes an internationally wrongful act.
  • Non-Discretionary Obligation:
    • Climate action is no longer optional or a matter of policy discretion—legal compliance is expected.
  • Corporate Regulation:
    • States must monitor and control emissions from private entities within their jurisdiction.
  • Loss and Damage:
    • The Court acknowledged that affected states may seek reparations for climate-related harm.
  • Global Scope:
    • Obligations apply universally and are erga omnes—owed to the international community as a whole.
About ICJ Advisory Opinions
  • Nature and Authority:
    • Advisory opinions interpret international law but are non-binding in nature.
    • However, they hold high persuasive value and moral authority in global governance.
  • Who Can Request:
    • Only the UNGA and UNSC have direct authority to request opinions under Article 96 of the UN Charter.
    • Other UN bodies must obtain approval from the General Assembly.
  • Procedural Aspects:
    • The ICJ can issue opinions without consent from the states involved.
    • It may decline requests that are vague or outside the legal scope of the referring body.
Implications for India
  • Shift in Climate Governance:
    • The advisory opinion strengthens global expectations of legal compliance, replacing earlier voluntary commitments.
  • Future Legal Risks:
    • India may face international legal scrutiny over lapses in domestic climate targets.
  • Enforceable NDCs:
    • India’s Nationally Determined Contributions (NDCs) now carry greater weight and may be treated as legally enforceable standards.
  • Policy Reinforcement:
    • Steps such as promoting renewables and phasing out fossil fuel subsidies receive legal legitimacy.
  • Transboundary Impact:
    • Neighbouring countries could raise cross-border climate damage claims under emerging international norms.
