Despite this, IEL has been progressively experiencing a shift towards ecocentric values (which awards Nature intrinsic value and rights). As observed by <a href=\"https:\/\/academic.oup.com\/edited-volume\/41336\/chapter-abstract\/352410642?redirectedFrom=fulltext\">Rajamani and Peel<\/a>, there is a \u2018reckoning\u2019 in IEL of \u2018ethical values, approaches, choices and conflicts\u2019 where \u2018non-anthropocentric values are gaining ground\u2019.<\/p>\n<p>The growing recognition of rights of Nature (RoN) (i.e. the assertion of Nature as a right-holding entity with legal personality) is an example of the above. Currently, a handful of Latin-American countries recognize RoN in their constitutions, legislation and case-law. The Advisory Opinion No. 32\/25 (<a href=\"https:\/\/corteidh.or.cr\/docs\/opiniones\/seriea_32_en.pdf\">AO-32\/25<\/a>) of the Inter-American Court of Human Rights (IACtHR), by acknowledging RoN, can drive a more ample protection of Nature in the region and in two ways. Fist, by driving normative and judicial recognition of RoN in domestic legal systems advancing State practice in favor of Nature\u2019s Rights. Second, by advancing a progressive incorporation of ecocentric principles into the legal fabric of international environmental instruments.<\/p>\n<p>This essay aims to analyze the legal implications of the AO-32\/25 acknowledgement of RoN for State Parties of the American Convention on Human Rights (ACHR) under the theory of conventionality control and its effects on IEL. It explores how RoN can contribute to build a more balanced notion of sustainable development based on ecocentric values. Finally, it argues that the AO-32\/25 recognition of RoN can, through conventionality control, catalyze State practice in Latin-America, which might, in turn, permeate IEL.<\/p>\n<p><strong>The Anthropocentric Hard Wiring of Early IEL<\/strong><\/p>\n<p>Anthropocentrism is based on a worldview that prioritizes humans\u2019 interests, where Nature is worth protecting for its instrumental value and utility (see <a href=\"https:\/\/opil.ouplaw.com\/display\/10.1093\/law:epil\/9780199231690\/law-9780199231690-e1943?rskey=hUJaO8&amp;amp;result=5&amp;amp;prd=OPIL&amp;amp;print\">Bosselmann<\/a>). Deeply hardwired in early IEL rhetoric is the anthropocentric ultimate goal of protecting the environment as a tool for securing human well-being (see <a href=\"https:\/\/doi.org\/10.1016\/j.esg.2022.100132\">du Toit and Kotz\u00e9<\/a>, p.11).<\/p>\n<p>Anthropocentric values can be viewed in every instrument that <a href=\"https:\/\/library.sprep.org\/sites\/default\/files\/2021-03\/international-environmental-law.pdf\">Dupuy and Vi\u00f1uales<\/a> (p.11) \u00a0have identified as the foundational backbone of IEL. For instance, the United Nations General Assembly (UNGA) <a href=\"https:\/\/www.ohchr.org\/en\/instruments-mechanisms\/instruments\/general-assembly-resolution-1803-xvii-14-december-1962-permanent\">Resolution 1803<\/a> highlights the rights of nations and peoples to exercise sovereignty over their \u2018natural wealth and resources\u2019 in pursuit of \u2018national development\u2019. The <a href=\"https:\/\/docs.un.org\/en\/a\/conf.48\/14\/Rev.1\">Stockholm Declaration<\/a> (Principles 1-4) claims that \u2018men\u2019 have a right to live in an environment that allows a life of \u2018dignity and well-being\u2019 for present and future generations. In the same vein, the <a href=\"https:\/\/www.un.org\/en\/development\/desa\/population\/migration\/generalassembly\/docs\/globalcompact\/A_CONF.151_26_Vol.I_Declaration.pdf\">Rio Declaration<\/a> (Principles 1 and 3) states that humans are at the \u2018centre of concerns\u2019 of sustainable development and are \u2018entitled\u2019 to an adequate life in \u2018harmony with nature\u2019. Similar considerations are found in other basal instruments like the <a href=\"https:\/\/www.un.org\/esa\/sustdev\/documents\/WSSD_POI_PD\/English\/POI_PD.htm\">Johannesburg Declaration on Sustainable Development<\/a> (paras. 16-18) and \u2018<a href=\"https:\/\/www.un.org\/en\/development\/desa\/population\/migration\/generalassembly\/docs\/globalcompact\/A_RES_66_288.pdf\">The Future We Want\u2019<\/a> (para. 6).<\/p>\n<p>\u2018Sustainable development\u2019, a key concept transversal to most previous instruments, serves as the scaffolding of all recent IEL, especially after the adoption of the <a href=\"https:\/\/www.un.org\/en\/development\/desa\/population\/migration\/generalassembly\/docs\/globalcompact\/A_RES_70_1_E.pdf\">2030 Agenda<\/a>. At its core, this concept is grounded on the notion that economic, social and environmental considerations are \u2018interdependent\u2019 and \u2018mutually reinforcing\u2019 pillars that must be balanced to achieve development. (see Rio Principle 4 and Political Declaration of the <a href=\"https:\/\/docs.un.org\/en\/A\/Conf.199\/20\">World Summit on Sustainable Development<\/a>, para. 5). Even if founded on the idea of \u2018balancing\u2019, in practice, sustainable development discourse is often used to \u2018rationalize\u2019 anthropocentric \u2018Earth system altering practices\u2019, pondering human interests over Nature\u2019s protection (cf. <a href=\"https:\/\/doi.org\/10.1163\/18760104-01603002\">Kotz\u00e9<\/a>, p. 222).<\/p>\n<p><strong>The Rise of Ecocentrism in IEL<\/strong><\/p>\n<p>Ecocentrism has progressively gained ground in IEL as a reaction to anthropocentric approaches\u2019 inability to attain structural environmental reforms and halt the crossing of critical planetary boundaries (cf. <a href=\"https:\/\/doi.org\/10.1016\/j.esg.2019.100003\">Kotz\u00e9 and Kim<\/a>, p. 4). It presses for the acknowledgement of Nature\u2019s intrinsic value and is mainly concerned with all ecological \u2018correlations and networks\u2019 that enable Earth\u2019s \u2018life-support systems\u2019 of which humans are only a part (cf. Bosselmann, paras. 16-18).<\/p>\n<p>Threads of ecocentric values can be appreciated in the <a href=\"https:\/\/ejcj.orfaleacenter.ucsb.edu\/wp-content\/uploads\/2018\/03\/1982.-UN-World-Charter-for-Nature-1982.pdf\">UN World Charter for Nature<\/a>. In the field of biodiversity conservation, treaties were originally motivated by economic interests surrounding the exploitation of species; however, over time, its focus pivoted towards conservation and the protection of ecosystem\u2019s inherent worth (see Dupuy and Vi\u00f1uales, p. 202). Notably, ecocentric values can be observed in the <a href=\"https:\/\/www.cbd.int\/convention\/text\">Convention on Biological Diversity<\/a> (preamble), and subsequent agreements of its conferences of parties (CBD <a href=\"https:\/\/www.cbd.int\/decision\/cop?id=7148\">COP5 Decision V\/6<\/a> and <a href=\"https:\/\/www.cbd.int\/doc\/decisions\/cop-07\/cop-07-dec-11-en.doc\">COP7 Decision VII\/11, Annex 1<\/a>) that highlight the significance of the ecosystem approach to conservation. Also, under the <a href=\"https:\/\/www.ramsar.org\/sites\/default\/files\/documents\/library\/current_convention_text_e.pdf\">Ramsar Convention<\/a>, the \u2018international significance\u2019 of wetlands is ascertained solely on their ecological characteristics (art. 2.2). Additionally, the preamble of the recent <a href=\"https:\/\/www.un.org\/bbnjagreement\/en\">Agreement on Marine Biological Diversity of Areas Beyond National Jurisdictions<\/a> (preamble) stresses the relevance of preserving biological diversity\u2019s intrinsic value.<\/p>\n<p><strong>The RoN Movement Is an Example of the General Turn Towards Ecocentrism<\/strong><\/p>\n<p>The rising RoN movement is also anchored in ecocentrism. It seeks the recognition of natural entities as right-holders that have legal standing, through guardianship, to request the cessation of deleterious human behaviour and integral environmental redress (see <a href=\"https:\/\/iseethics.wordpress.com\/wp-content\/uploads\/2013\/02\/stone-christopher-d-should-trees-have-standing.pdf\">Stone<\/a>, p. 463). The UNGA has acknowledged that RoN can help promote sustainable development in real <a href=\"http:\/\/files.harmonywithnatureun.org\/uploads\/upload1530.pdf\">\u2018harmony with nature\u2019<\/a>. Currently, RoN are protected in constitutions, in Ecuador and Bolivia, and extended legislation and case-law in ACHR States, including <em>inter alia <\/em>Brazil, Mexico, Panama and Peru, as well as other countries worldwide (AO 32-25, para. 286).<\/p>\n<p>On the one side, supporters of RoN contest that securing Nature\u2019s legal personality can, in practice: (i) guarantee access to justice through ample legal standing to cease and repair ecosystemic damage in absence of direct human affectations (Stone, 463-473); (ii) increase political and public surveillance of otherwise ignored environmental issues (<a href=\"https:\/\/doi.org\/10.1093\/jel\/eqab021\">Wesche<\/a>, p. 554), and (iii) advance nature-based policies aimed at protecting critical ecosystems (<a href=\"https:\/\/doi.org\/10.1007\/s10745-023-00420-1\">Gilbert et. al.<\/a>, p. 363), designed with the participation of local communities, often indigenous populations, as guardians. On the other side, empirical studies criticize RoN for the lack of clear regulations on liability in the guardianship regimes (see <a href=\"https:\/\/doi.org\/10.1016\/j.ecolecon.2024.108193\">Kahui et. al.<\/a>, p. 221), and of political enforcement in \u2018weak governance settings\u2019 (cf. Wesche, p. 555).<\/p>\n<p>Although further research is required to ascertain the effectiveness of the different RoN frameworks, its recognition arguably has, at least, a strong symbolic force capable of harmonizing sustainable development with Nature\u2019s needs. The IACtHR underlined this symbolic power and stressed its importance in the context of climate change.<\/p>\n<p><strong>The IACtHR Rides the Wave of Ecocentrism with RoN<\/strong><\/p>\n<p>The climate change framework is grounded on the anthropocentric <em>Leitmotif <\/em>of preventing dangerous human interference with the climate system, mitigating emissions and stabilizing the global average temperature to secure inter-generational survival and address climate impacts <em>on<\/em> <em>humans<\/em> (see <a href=\"https:\/\/unfccc.int\/resource\/docs\/convkp\/conveng.pdf\">UNFCCC<\/a>, art. 2 and <a href=\"https:\/\/unfccc.int\/sites\/default\/files\/english_paris_agreement.pdf\">Paris Agreement<\/a>, art. 2). In the AO-32\/25, the IACtHR implicitly questioned this paradigm by highlighting the relevance of shifting towards a climate governance model deep-seated in ecocentrism that prioritizes the protection of the climate system as a means to harmonize sustainable development with Nature\u2019s needs.<\/p>\n<p>The AO-32\/25 on State obligations regarding climate change and human rights was rendered by the Court in July 2025 on request of Chile and Colombia. In this AO, the IACtHR firmly rode the wave of ecocentrism by asserting that, under the ACHR, acknowledging the right of Nature to preserve its ecological processes builds to a \u2018truly sustainable development model\u2019 aligned with \u2018planetary boundaries\u2019. Furthermore, it claimed that advancing to a \u2018paradigm\u2019 that protects ecosystem\u2019s \u2018inherent rights\u2019 is pivotal for securing its long-term integrity (para. 279). Finally, it stated that normatively protecting RoN is \u2018fully compatible\u2019 with the general obligation to adopt domestic legislation to progressively protect social, economic, cultural and environmental rights (paras. 281).<\/p>\n<p>Some clarifications are pertinent to dissipate the smoke that blurs the general understanding of commentators surrounding the scope and reach of the Court\u2019s pronouncement. First, it should be noted that the Court did not impose an obligation on ACHR to recognize RoN. Nonetheless, the Tribunal <em>did<\/em> send a strong signal regarding the desirability to advance in this direction and its compatibility with the object and purpose of the ACHR. Second, the Court did not recognize <em>locus standi <\/em>to Nature to bring cases (through its guardians). Consequently, the right of legal persons to appear before the Tribunal as potential victims remains reserved to Indigenous Peoples and unions, federations and confederations under the current rules of the Inter-American System (see <a href=\"https:\/\/www.corteidh.or.cr\/docs\/opiniones\/seriea_22_ing.pdf\">AO 22-16<\/a>, paras. 72-84 and 85-105).<\/p>\n<p>Overall, the IACtHR\u2019s stance regarding RoN has no procedural influence in the context of future contentious procedures: Nature will not have its day in Court (as a direct victim, at least!). However, the Court\u2019s reflections on the central role of RoN in harmonizing sustainable development might ultimately influence IEL through the mechanism of conventionality control, as discussed below.<\/p>\n<p><strong>Conventionality Control Can Drive State Practice and Impact IEL<\/strong><\/p>\n<p>The Court\u2019s standards on RoN have utmost importance due to the conventionality control doctrine fiercely ingrained in the Tribunal\u2019s jurisprudence. This doctrine claims that there is an international obligation on all public authorities of all State Parties to <em>ex officio<\/em> interpret and, if necessary, amend domestic legislation, in a manner compatible with the ACHR, as interpreted by the IACtHR in its contentious and advisory capacity (see <a href=\"https:\/\/opil.ouplaw.com\/display\/10.1093\/law-mpeipro\/e3634.013.3634\/law-mpeipro-e3634\">Burgorgue-Larsen<\/a>, para. 1-3, 13-28).<\/p>\n<p>In practical terms, this means that the Court\u2019s interpretation carries normative authority beyond the specific cases it decides. Hence, the decision of the Court in its Advisory Opinion No. 32 (AO-32) to recognize RoN as integral to the realization of sustainable development and environmental protection under the Convention, would have to be\u00a0<em>officiously internalized<\/em>\u00a0by domestic judges, legislators, and administrative bodies across the region. In more receptive or \u201ccompliant\u201d States\u2014those with a demonstrated record of aligning domestic norms with Inter-American jurisprudence\u2014this could catalyze the judicial and legislative entrenchment of Nature\u2019s rights. The doctrine thus possesses transformative potential: it could convert an interpretive innovation at the regional level into binding normative change within national legal systems.<\/p>\n<p>Moreover, if AO-32 were to articulate an expansive recognition of RoN, it could exert influence well beyond the Inter-American system. The consolidation of RoN practices in Latin America\u2014driven by judicial dialogue, transnational advocacy networks, and regional norm diffusion\u2014may eventually shape the evolution of IEL more broadly. This could manifest in the progressive incorporation of ecocentric principles into\u00a0soft law instruments, multilateral environmental agreements, or interpretive developments under existing regimes. In this sense, the IACtHR\u2019s engagement with RoN would not only reflect but also reinforce a paradigmatic shift in global environmental governance: from an anthropocentric framework of rights and obligations toward a more relational, ecocentric conception of legal subjectivity and planetary stewardship.<\/p>\n<p><strong>Conclusions<\/strong><\/p>\n<p>As a corollary, three major conclusions can be drawn.<\/p>\n<p>First, as Rajamani and Peel observed, IEL is experiencing a paradigmatic shift from anthro to ecocentrism. The RoN movement fits into this growing trend.<\/p>\n<p>Second, the IACtHR\u2019s did not recognize <em>locus standi <\/em>to Nature (through its guardians) to appear as a claimant before the Court in a future contentious case. The overall relevance of the Tribunal stance is that it advances the idea that RoN hold a sturdy symbolic power capable of enhancing climate governance by more effectively harmonizing sustainable development with Nature\u2019s protection.<\/p>\n<p>Ultimately, the Court\u2019s standards could trigger, through conventionality control, wider judicial and legislative recognition of RoN in Latin-America. This may advance State practice in favor of RoN and, subsequently, foster its recognition in international forums and instruments pushing further the wave of ecocentrism in IEL. In this equation, conventionality control\u2019s ability to drive State conduct is determinant.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>International Environmental Law (IEL) was imagined through the prism of anthropocentric values (which allocates worth to Nature based on its utility for humans).
