From the Court to Treaty Arrangements: Exactly How the ICJ Ruling Might Enhance the Global Plastics Treaty

Released August 6, 2025

By Andrés Del Castillo, Senior Attorney, Helionor de Anzizu, Elder Attorney, Joie Chowdhury, Senior Attorney, Dharmesh Shah, Consulting Senior Citizen Advocate (Plastics Treaty), and Cate Bonacini, Senior Citizen Communications Campaign Specialist at the Center for International Environmental Law, Semee Rhee, Global Policy Consultant, Break Free from Plastic, and with the support of Alexandra Harrington, Chair, IUCN WCEL Arrangement on Plastic Air Pollution Task Force


When the International Court of Justice (ICJ) provided its landmark environment ruling in July, it did not simply reaffirm that States have a binding legal task to avoid climate damage and protect human rights from the effects of environment change. The point of view additionally represents a major landmark for environment activity– it offers federal governments brand-new lawful utilize to attend to one of today’s fastest-growing environmental risks: the complete life cycle of plastics.

Currently, as UN Participant States gather in Geneva, Switzerland for the resumed 5th session of the intergovernmental negotiating board to advance a plastics treaty (INC- 5 2, focus is transforming to exactly how this recent ICJ ruling can– and need to– inspire greater ambition and liability in crafting the world’s very first treaty to deal with plastic pollution across its whole life process.



The ICJ ruling adhered to a phenomenal joint effort by youth campaigners from the Pacific and beyond , Vanuatu, the Pacific Islands, and climate-affected countries requiring legal quality on States’ climate responsibilities. While the judgment made headlines around the globe, an essential concern stays: What impact does an Advisory Viewpoint actually have?

As delegates convene for the first ecological treaty negotiation since the ICJ Advisory Point of view was provided, mediators and onlookers alike are asking exactly how this historical lawful criterion can aid form– and enhance– the path towards a legitimately binding contract on plastic pollution.

The Impact of Advisory Opinions on Discussing Fora

One doesn’t need to look long or tough to locate examples of ICJ opinions that took place to affect treaty negotiations. There are examples of ICJ Advisory Point of views that were provided prior to or during treaty negotiations and took place to influence those procedures. The 1996 ICJ Advisory Opinion on the Legality of the Threat or Use Nuclear Defense was issued practically a decade prior to the Treaty on the Prohibition of Nuclear Defense. In that Advisory Viewpoint, 2 key elements emerged:

  1. A demand to clarify lawful elements that the Court did not totally fix, specifically using nuclear weapons under all circumstances.
  2. A powerful dissenting opinion from Judge Christopher Gregory Weeramantry insisted the illegality of nuclear tools under global law.

Together, these items assisted shape the discussion around the requirement for a treaty, adding to the momentum promoting arrangements and eventually, the treaty’s content.

The Fossil Fuel-Plastics Link

During the preliminary of the Plastics Treaty settlements, the UN Secretary-General established the tone by affirming, in political terms, what science has long explained and what countries need to confront head-on within the negotiations: “Plastics are fossil fuels in an additional form.” Indeed, 99 percent of plastics are made from nonrenewable fuel sources, the leading source of climate adjustment and the leading resource of international greenhouse gas (GHG) discharges. It has been clear from the beginning that to resolve the major chauffeurs of plastic contamination, countries need to reduce plastic manufacturing.

It is feasible to contextualize arguments from the ICJ Advisory Opinion and use them to the Plastics Treaty room when it concerns existing commitments. Some professionals have actually currently started to do that, and in the days that complied with the Advisory Opinion, over 47 UN independent civils rights experts wrote to advise nations to carry out the Advisory Opinion throughout INC- 5 2

There is a riches of evidence connecting climate modification and plastics. A current stock showed greater than 6, 400 peer-reviewed clinical short articles on subjects varying from plastics and exhausts to carbon sequestration and the Planet’s radiation budget. One research demonstrates that under a business-as-usual circumstance, plastic manufacturing could account for as much as 31 percent of the global carbon spending plan by 2050

When the ICJ Advisory Opinion clearly mentions that … failure of a State to take ideal action to safeguard the environment system from GHG discharges– consisting of via fossil fuel production, fossil fuel usage, the providing of nonrenewable fuel source exploration permits or the arrangement of fossil fuel subsidies– may constitute a globally wrongful act attributable to that State,” it strengthens the lawful basis for ambitious States to suggest that uncontrolled plastic production is incompatible with worldwide climate commitments. This explicit acknowledgment of the demand to attend to discharges from both plastic manufacturing and plastic consumption gives a solid lawful structure for countries to go after both approaches within the framework of the Plastics Treaty.

Paving the Way for the Plastics Treaty

Given That the Plastics Treaty negotiations started in 2022, a string of choices from significant worldwide courts and tribunals has actually laid the foundation for States taking enthusiastic activity against plastic contamination.

In 2024, the International Tribunal of the Law of the Sea (ITLOS) released an Advisory Opinion on Environment Adjustment The Advisory Viewpoint makes the argument that anthropogenic GHG emissions drop within the range of “air pollution of the aquatic atmosphere” as specified under the United Nations Convention on the Legislation of the Sea (UNCLOS) which States need to take all necessary actions to prevent, reduce, and control aquatic pollution by anthropogenic GHG exhausts. The Tribunal further specified that the current international environment lawful routine is applicable but not unique in establishing States’ legal duties in relation to environment change. Other sources of worldwide legislation are additionally relevant and suitable.

The ITLOS Advisory Point of view additionally recognizes that while the existing climate treaty regime is significant, it wants to totally satisfy the climate-relevant obligations laid out under UNCLOS, such as the responsibilities to protect and preserve the aquatic atmosphere, along with to prevent, lower, and control pollution of the marine atmosphere ( UNCLOS Arts 192 and 194

Earlier this year, the Inter-American Court of Civil rights released an Advisory Point of view on Climate Emergency Situation and Human Rights It stresses that traditional international regulation continues to be main to the context, notably via commitments to avoid transboundary injury and to take part in great faith in worldwide collaboration. The obligation to cooperate need to take place through financial methods, modern technology transfer, capacity structure, and the facility of international discussion forums and the formula of joint international plans.

The ICJ Advisory Opinion builds on both of these opinions by resolving a number of concerns that are additionally relevant to plastics, specifically, plastic manufacturing and plastic-related GHG discharges, while leaving some concerns unresolved and requiring States to bargain proper solutions.

Given the far-reaching recognition of the right to a tidy, healthy and balanced, and sustainable setting (R 2 HE) in nationwide, regional, and global instruments, the Court critically acknowledged the right as a binding norm of worldwide legislation and a precondition for the pleasure of lots of various other human rights. To put it simply, States can not claim compliance with civils rights treaties unless they also ensure environmental protection.

The ICJ environment ruling additionally affirmed the long-recognized right to health and wellness (para.379 It additionally highlighted the urgent demand for States to take binding action versus climate adjustment, including re gulating personal emissions, and especially highlighted that the conduct that results in emissions , such as manufacturing or providing licenses or aids for fossil fuels production and usage, might comprise a worldwide wrongful act. This might include plastic manufacturing, the development of plastic manufacturing ability, and associated licenses– across the complete life process, consisting of the production of main, additional, and final produced plastic– and aids.

Recognizing the Origin: Fossil Fuels and the Climate Crisis

While science has actually continually pointed out that nonrenewable fuel sources are the root cause of climate change, climate treaties (e.g., the United Nations Framework Convention on Climate Change [UNFCCC], the Paris Arrangement, the Kyoto Protocol, and the Kigali Modification to the Montreal Protocol) have continued to be silent about them. This end result shows the impact of fossil fuel-producing States and their rate of interests during the arrangement procedure. Ever since, Parties have actually been working to right this wrong to make certain a coherent and worldwide method to fossil fuels. In the case of the UNFCCC, it took decades for the Conference of the Celebrations to explicitly mention nonrenewable fuel sources

Attending to plastic manufacturing is as mission-critical to the Plastics Treaty as pointing out nonrenewable fuel sources is to climate treaties. Participant States need to not duplicate the mistakes of past arrangements by omitting the root causes of the plastics situation from the treaty’s scope and passion.

Creating a Plastics Treaty with the ICJ Advisory Viewpoint in Mind

While the 140 -page ruling discuss many themes, six are specifically relevant to the Plastics Treaty which Participant States ought to consider when bargaining it.

1 The Obligation to avoid Damage

The ICJ attested that States have a binding legal obligation to prevent climate harm. We know that 80 percent of the GHG discharges throughout the life cycle of plastics occur throughout manufacturing. Consequently, for nations to prevent legal responsibility for conduct that contributes to carbon discharges, they require to implement the ICJ’s judgment by attending to both plastic manufacturing and consumption.

Heading right into INC- 5 2, the working message (the Revised Chair’s Text lacks any kind of straight reference to the environment system or GHG, in spite of the immediate need to clearly address environment issues, consisting of discharges , within the future treaty. When developing a target for lowering plastic manufacturing, it will certainly be necessary to consist of one that reduces virgin plastic production according to the environment goal of 1 5 ° C , as both scientific research and law call for.

2 Scientific Attribution

The ruling likewise recommends making use of clinical acknowledgment and harm/injury as linked aspects, highlighting that scientific research is essential in establishing damages in the context of environment modification.

The same reasoning puts on the damages caused by plastic contamination. There is an expanding body of clinical evidence linking mini- and nanoplastics, chemicals of concern, emissions, and releases to effect on health and wellness– consisting of, however not restricted to, cancer cells and endocrine disruption, biodiversity loss, and climate modification.

3 Legal Attribution

GHG exhausts, such as plastic air pollution, are a transboundary issue that commonly includes numerous States. Here, the judgment states, “the guidelines on State obligation can attending to situations where damages is caused by multiple States taking part in wrongful conduct, which the duty of a solitary State for damages might be conjured up without conjuring up the duty of all States that might be liable.” (para. 430 Under this policy, a solitary State, amongst multiple States and stars triggering injury, can still be held responsible for breaching its obligation and for adding to the collective injury caused.

This judgment is specifically substantial for transboundary environmental worries such as plastic air pollution that involve multiple States creating worldwide environmental damage, where shrouded responsibilities and averted duties make it tough to connect injury. Nonetheless, with this judgment, the Court additionally stresses the general regulation of State responsibility and consequently provides a more clear lawful path to hold States to account.

4 Personal Actors

Regarding private actors, the Court has highlighted that States need to regulate exclusive discharges. States are under a lawful task to control GHG exhausts– including from exclusive companies and capitalists from all sectors, especially the petrochemical market:” [a] State might be responsible where, as an example, it has failed to work out due diligence by not taking the essential regulative and legal steps to limit the amount of emissions brought on by exclusive stars under its jurisdiction.” (para.428 This judgment will certainly have an impact on company actors in the petrochemical industry, as petrochemicals are derived from fossil fuels.

Most importantly, even where a State has previously granted licenses or otherwise stopped working to act, the legal commitment to decrease discharges and change away from nonrenewable fuel sources continues: “The violation by a State of its international responsibilities does not extinguish its underlying obligation of efficiency.” (para.446

5 Concrete Targets and Procedures

To satisfy commitments under international legislation, consisting of the environment and human rights routines, in addition to under UNCLOS, it is crucial for States to adopt concrete steps and objectives. In the context of global targets, the ICJ verified that the 1 5 ° C target is the key temperature objective agreed by Celebrations under Post 2 of the Paris Contract, recognizing it as the criteria for restricting international warming. It stressed the urgency of action, the void between existing commitments and the 1 5 ° C goal, and the obligation of States to show due diligence to satisfy this target.

Concrete targets and steps developed under the Plastics Treaty would certainly not only meet these responsibilities yet additionally supply the essential lawful framework and clarity– especially for the economic sector– in our interconnected globe.

In addition, a global main plastic manufacturing target would help define and quantify States’ commitments under UNFCCC and UNCLOS, while preferably lining up with the Paris Arrangement’s temperature level goal. To execute it successfully, nations would require to adopt national targets that add to a worldwide cap, allowing for a degree of flexibility based upon nationwide conditions.

6 Repair

Among the ruling’s clearest affirmations is that historic exhausts issue, and those suffering from the influences of environment destruction have a right to correct and repair. A lot of the neighborhoods most influenced by climate change stay in countries that birth less historic responsibility for GHG discharges. When considering solutions or reparations, it is necessary to check out those nations that are the highest historic emitters.

Redress under the law of State responsibility entails halting unsafe conduct, providing guarantees of non-repetition, and offering complete repair, including restitution or restoring the circumstance before the violation of international regulation; economic payment as relevant; and fulfillment, which may take the type of formal apologies or education of culture about climate change. Since climate commitments are owed to all various other States (” erga omnes partes ), any State might require cessation, warranties, or adjustment, even if it is not directly wounded.

Again, there is substantial thematic overlap with plastic pollution. Ninety percent of all the plastic that was ever before made still exists. This heritage plastic is a major trouble that Member States should emulate in the treaty. Like with GHG emissions, some countries birth even more historical duty than others. To address this, the Plastics Treaty will certainly need a committed article that attends to historical plastic contamination. AOSIS and various other nations have actually likewise shared the wish to establish a committed fund or subfund to sustain remediation initiatives.

Verdict

The ICJ judgment delivers a clear, daring, and distinct opinion on a politically delicate problem. As the first-ever required to craft a legally-binding tool that deals with the complete life cycle of plastic, the future Plastics Treaty negotiations are an essential test of exactly how the ruling will be utilized in practice. But the viewpoint will certainly not be enough.

Until now, the Plastics Treaty negotiations have depended on agreement decision-making, enabling any type of one country last word. With Participant States that have a beneficial interest in proceeding petrochemical production in the area, consensus requires decreasing decisions to the lowest common denominator. Grabbing a Plastics Treaty that remains in line with the ruling will certainly call for States to climb over obstructionism and release all of the devices that multilateralism supplies, consisting of voting. Doing so will certainly require legal clarity and political nerve– equally as the Court has demonstrated.

“the inquiries presented by the General Assembly stand for more than a legal issue: they worry an existential trouble of worldly proportions that imperils all types of life and the really health of our world. International law, whose authority has been invoked by the General Setting up, has an essential however eventually minimal duty in fixing this issue. A complete option to this difficult, and self-inflicted, trouble calls for the contribution of all fields of human expertise, whether law, science, business economics or any other.” ICJ, par. 456
