WYCJ Symposium: International Court of Justice Advisory Opinion, Climate Justice, Youth & Human Rights

Introduction

This opening article in the symposium explains the campaign led by World’s Youth for Climate Justice to obtain an advisory opinion from the International Court of Justice on climate change and human rights.

The central goal is to clarify what obligations states have under international law to protect the rights of present and future generations from the harmful effects of climate change.

The article presents the campaign as both a legal strategy and a youth-led justice movement.

Origins of the Campaign

The movement began in the Pacific region through Pacific Island Students Fighting Climate Change, formed by students at the University of the South Pacific.

Because climate change is a global issue, the initiative later expanded into WYCJ, a broader international youth coalition.

The article emphasizes that Pacific island communities were among the first to push this legal strategy because they are among those most threatened by sea-level rise and extreme climate impacts.

Why an ICJ Advisory Opinion?

The proposed legal question is:

What are the obligations of states under international law to protect the rights of present and future generations against the adverse effects of climate change?

The article argues that an ICJ advisory opinion could become the most authoritative judicial statement yet on:

• climate mitigation duties

• adaptation responsibilities

• human rights impacts of climate change

• obligations toward children and youth

• intergenerational equity

Although advisory opinions are not binding judgments, they carry major legal and moral authority.

Bridging Fragmented Areas of Law

A key theme is that climate law and human rights law often operate separately.

The article argues an ICJ opinion could connect:

• the United Nations Framework Convention on Climate Change system

• international human rights treaties

• broader principles of international law

This would help clarify how environmental harm translates into legal duties toward people.

Intergenerational Equity

The campaign strongly relies on the principle of intergenerational equity.

This means current generations should not impose irreversible environmental damage on future generations.

The author argues that climate change uniquely raises this issue because today’s emissions can shape the lives of unborn people for decades or centuries.

An ICJ opinion could help define:

• whether future generations hold legal interests

• what duties states owe them

• how present-day policy should account for long-term harms

Climate Change as a Human Rights Issue

The article explains two major legal pathways linking climate change and rights.

1. Climate change harms existing rights

For example:

• right to life

• health

• housing

• private and family life

• property

2. Climate change threatens the right to a healthy environment

Where that right is recognized, environmental degradation directly violates protected human interests.

Thus, the campaign seeks a clear human-rights-based interpretation of climate obligations.

Youth and Climate Justice

The article places young people at the centre of the movement.

It argues youth face:

• the longest exposure to future climate harms

• limited influence over present policy decisions

• underrepresentation in global governance structures

Because of this democratic gap, courts and legal institutions have become an important forum for youth action.

The campaign therefore frames itself as both:

• a legal initiative

• a generational justice movement

Why Youth Cannot Apply Directly

The author notes that WYCJ itself cannot directly ask the ICJ for an advisory opinion.

Only authorized UN bodies may do so, especially the United Nations General Assembly.

The campaign therefore depends on states sponsoring and supporting a UNGA resolution.

The article highlights Vanuatu as an important supporter after announcing in 2021 its intention to pursue the initiative through the General Assembly.

Why States Matter

According to the article, governments have responsibilities to:

• protect their populations

• uphold human rights

• listen to youth concerns

• support climate justice efforts internationally

So while the campaign is youth-led, success ultimately depends on state action.

Conclusion

Manon Rouby presents the proposed ICJ advisory opinion as a historic opportunity to strengthen climate justice through international law.

The article argues that such an opinion could:

1. Clarify state climate obligations

2. Link climate law with human rights law

3. Advance intergenerational equity

4. Empower youth voices globally

5. Push governments toward stronger action

The post frames climate change not only as an environmental crisis, but as a humanitarian and legal crisis requiring response at the highest international level.

Manon Rouby is described as a French environmental lawyer based in the United Kingdom and Academic Coordinator for World’s Youth for Climate Justice.
