Protecting the Environment: What do States have to do?
Updated: Jun 28, 2020
‘[T]he environment is not an abstraction but represents the living space, the quality of life and the very health of human beings, including generations unborn’
International Court of Justice in Legality of the Threat or Use of Nuclear Weapons (Advisory Opinion)  ICJ Rep 226, 
Environmental Law and Human Rights have, until recently, seemed to be un-marriable ideas. However, they are more complementary than many may imagine. Global attention on environmental degradation and the resulting climate change has steadily grown over the previous decades. The global reach of social media campaigns has encouraged the young generation to stand up and strike for change. Countless people have been petitioning governments for change, such as declaring a climate emergency, but the question remains, what are governments actually required to do under international law? Are these requirements sufficient to combat alarming environmental threats?
In 2015, the United Nations General Assembly (‘UNGA’) adopted the 2030 Agenda for Sustainable Development, outlining 17 Sustainable Development Goals (‘SDG’) centered on peace and prosperity.[i] The goals call for global action to end poverty and other deprivations, improve health, education and economic growth, reduce inequalities, and create communities to manage climate change and preserve ecosystems. Although these goals are not binding hard-law, they were unanimously accepted by all UN Member States and embody the most vital issues facing humanity and the global community.[ii]
The environmental issues among these are:
SDG 12: Pollution
The issue of pollution encompasses air, ground, and water pollution and the disposal of chemicals, toxic waste, and plastic, posing a threat to ecosystem function, human health, and biodiversity.[iii] The World Health Organization estimated that 1.6 million deaths and 45 million disability-adjusted life years could have been prevented in 2016 alone with ‘sounds management and reduction of chemicals in the environment’.[iv] The UN Environment Programme has reported that solutions to this problem do exist; however, ‘more ambitious, urgent and worldwide action is needed by all stakeholders’.[v]
SDG 13: Climate Change
Following only plastic pollution in our oceans, this is perhaps the most publicised environmental threat, though misinformation and misconstrued reports are widespread. Going back to basics, climate change, or global warming, is the result of greenhouse gases (‘GHG’), such as carbon dioxide and methane) in the Earth’s atmosphere trapping heat, warming the Earth like a greenhouse.[vi] To date, an increase of 1°C since pre-industrial times has already significantly impacted many regions, especially in terms of extreme weather and rising sea levels.[vii] The UN Intergovernmental Panel on Climate Change (‘IPCC’) published a Special Report on Global Warming of 1.5°C (‘SR15’) in late 2018.[viii] The IPCC concluded that the impacts of 2°C of global warming would be significantly worse than if we were able to keep global warming to 1.5°C. It then estimated that 1.5°C would be reached between 2030 and 2052. However, as Myles Allen, a lead author of the SR15, states, this ‘doesn’t mean we have 12 years to act: it means we have to act now’.[ix]
SDG 15: Biodiversity Loss
Biological diversity is the ‘variability among living organisms. [T]his includes diversity within species, between species and of ecosystems’.[x] The risk of complete species extinction is measured using the Red List Index - a scale from 0 (all species extinct) to 1 (no threat to any species).[xi] Human activity, including agriculture, poaching and trafficking, deforestation, fishing, and energy production use, has resulted in biodiversity loss at an ‘alarming rate’.[xii] Accordingly, in 1993 the Index stood at 0.82, dropping to 0.73 by 2019. This loss not only undermines the intrinsic ‘ecological, genetic, social, economic, scientific, educational, cultural, recreational, and aesthetic’ value of biodiversity, but also threatens ‘food security, access to water, [and the] health of the rural poor and people worldwide’.[xiii]
International Environmental Law
Enter International Environmental Law (‘IEL’), a see-saw balancing two foundational ideas:[xiv]
State sovereignty: a State may use the natural resources within its territory in any way it sees fit.[xv]
The Do No Harm Principle: a State may not use its own territory in a way that harms the territory of another State.[xvi]
IEL centres around the use of a State’s own territory. It holds that I may plant or destroy or use anything in my own backyard as long as that action doesn’t cross the fence and harm your garden.[xvii] However, environmental phenomena are fundamentally cross-border issues as the wind, sea, and migration patterns don’t follow human-delineated lines.[xviii]
Additionally, there are three main issues with the law itself which undermine its potential efficacy.
1. Enforcement and Content of Obligations
IEL, in essence, is comprised of negative obligations rather than positive ones. For example, if the trees that grow along our fenceline are shared - IEL would require you, as a figurative State, to NOT take action that would harm those plants. This can be compared with a positive area of law, such as human rights, which, if applied to the environment, would require you to take actual action to ensure the trees live, it would require you to regularly water and prune or fertilise, giving the trees what they need to thrive. This is the simple difference: IEL says don’t harm, positive areas of law say take action.
Despite the myriad treaties, conventions, and affirmed custom which govern States in respect of the environment, what States must actually do is not black and white. Most notably, the concept of common but differentiated responsibilities means that States are required to “do what they can”.[xix] Developed countries must contribute more than developing nations. This means that end goals may be defined, but the contribution of each State to that goal is not stated, blurring the line between hard and soft law. Such an approach may be equitable, but it is not enforceable. For example, the goal of limiting global warming to 1.5C outlined by the United Nations Framework Convention on Climate Change, Paris Agreement, and Kyoto Protocol don’t require States to reach a specific reduction in emissions. States simply pledge their commitment to limiting global warming to 1.5°C. This lack of clear obligations results in States not being able to be held liable by other States. State A cannot say to State B that it isn’t doing its part because neither knows what State B’s ‘part’ is.
Further, even where multilateral environmental agreements outline general obligations, they fail to create enforcement regimes.[xx] IEL takes a facilitative approach - where a country does not uphold its obligations (if they can be discerned), it is not punished, but rather assisted in reaching its goals.[xxi] Though this may be preferable in terms of achieving the end goal, IEL faces the same criticism as Public International Law (‘PIL’) - it is a toothless tiger, creating substantive obligations but not enforcing them.
2. Invocation of State Responsibility
Further to the issue of enforcement are the questions of invocation and attribution. Although the conduct of private entities can be attributed to a State in certain circumstances (meaning the State is liable), the rise of non-state actors and transnational enterprises has increased the difficulty of attributing environmental damage to a State.[xxii] If action can be attributed to a State, it is then a question of who holds that State responsible. The International Court of Justice (‘ICJ’) system is a bilateral one. Based on the principle of reciprocity, the ICJ requires an applicant, a respondent, and provable damage/injury.[xxiii] This may be ideal for disputes between two States regarding a migratory species or a cross-border river. However, this system isn’t ideal for damage to the ‘global commons’ (resources belonging to all, such as space). Many Multilateral Environmental Agreements allow for non-injured States to invoke the responsibility of another State, but the claimant is limited to a request ‘that the wrongful conduct cease’ and ‘a demand for reparation on behalf on the injured [S]tate’.[xxiv]
3. Environmental damage is ‘often irreversible’, so prevention is vital.
Finally, even if IEL is clear, enforceable, and invocable, its obligations are still inherently negative. In its 1997 Gabcikovo-Nagymaros decision between Hungary and Slovakia, the ICJ observed that environmental damage is ‘often irreversible’, so prevention is vital.[xxv] Prevention fundamentally requires proactive, positive action. But IEL and even PIL more generally are reactive. IEL is lacking in positive obligations. The only active action a State must take is to conduct an Environmental Impact Assessment when undertaking development which poses a reasonable and foreseeable risk to the environment, though this doesn’t ensure damage won’t occur.[xxvi] For example, the Deepwater Horizon oil spill in the Gulf of Mexico occurred even after the USA conducted an EIA prior to approving the offshore drilling.[xxvii]
Human Rights as an Alternate Approach
The International Bill of Rights consists of the Universal Declaration of Human Rights (‘UDHR’), the International Covenant on Civil and Political Rights, and the International Covenant on Economic, Social and Cultural Rights.[xxviii] Many of the rights contained in the International Bill are reiterated in regional conventions, such as the European Convention on Human Rights (‘ECHR’), the African Convention on Human Rights, and the Inter-American Convention on Human Rights.[xxix] The UNGA has affirmed that ‘each State has a prime responsibility and duty to protect, promote and implement all human rights and fundamental freedoms’.[xxx] This encompasses the obligation to prevent third parties from interfering with or violating human rights, and the positive obligation to take ‘deliberate and concrete’ measures aimed at full implementation of human rights.[xxxi]
There can be significant overlap between environmental harm and violation of human rights. The UN Special Rapporteur on Human Rights and the Environment, reports that continued global biodiversity loss threatens the ‘basic human rights to life, health, food and safe water’.[xxxii] Similarly, climate change threatens:[xxxiii]
the right to life, the right to adequate food, the right to the enjoyment of highest attainable standard of physical and mental health, the right to adequate housing, the right to self-determination, the right to safe drinking water and sanitation and the right to development.
This has resulted in the innovative approach of bringing actions under IHRL to require States to take certain action in line with IEL obligations. Early cases demonstrating the connection between environmental damage, human rights violations, and even international crimes were ‘brought against Shell for their actions in Nigeria and against Unocal for their actions in Burma’.[xxxiv]
The recent, landmark case Urgenda Foundation v The State of the Netherlands was brought in the Netherlands’ domestic legal system.[xxxv] This case was an action brought by the Urgenda Foundation on behalf of almost 900 Dutch citizens. The Hague Court of Appeal held that the Netherlands’ commitment reduce GHG emissions by 17% by 2020 was not sufficient to fulfil its positive duty of care under ECHR Articles 2 and 8.[xxxvi] These Articles protect the right to life and the right to respect for private and family life respectively. The Hague Court of Appeal acknowledged that climate change is a global issue and it could ‘only intervene in the emissions from Dutch territory’. However, it ultimately determined the Netherlands must change its target to 25% GHG emission reduction by 2020 in order to fulfil its duty of care to its people and protect their rights from ‘the real threat of climate change’. This is a vital example of citizens demanding greater action from States to combat climate change.
In a similar vein, a group of Australian Torres Strait Islanders have recently lodged a complaint with the UN Human Rights Committee alleging Australia’s failure to adequately reduce GHG emissions and take proper action to protect coastal areas has resulted in breaches of multiple UDHR articles.[xxxvii]
Big Problems, Small Solutions
The focus of the Article 33 Institute and this article is, of course, international law - the relations between and actions of States. However, it would be remiss not to mention perhaps the most important and immediate solution: individual action. A list of personal and simple changes one can make can be found here and here. In essence, the ‘reduce, reuse, recycle’ campaign says it simply and best. Reduce plastic and carbon consumption, have reusable alternatives on hand, and recycle where possible. More so than any State action or legal changes, individual action has an immediate impact.
