The UN's Expanding Role in Climate Action and Global Education: Mid-2025 Update

As climate threats escalate and educational gaps widen, the United Nations is sharpening its global strategy through legal interventions, major summits, and education-based frameworks. The first half of 2025 has seen landmark developments in both global education and environmental policy, setting new precedents for international cooperation and legal accountability.


Legal Climate Action: A Historic Ruling


In a watershed moment, the International Court of Justice (ICJ) issued a July 2025 advisory opinion stating that countries have a legal obligation to reduce human-caused greenhouse gas emissions. This ruling affirms the right to a clean, healthy, and sustainable environment as part of international human rights law. Though non-binding, the opinion lays critical groundwork for future litigation and financial responsibility for climate damages, particularly from high-emitting nations to vulnerable developing states.


Legal scholars suggest the opinion may significantly influence future climate-related court cases, shaping how governments, corporations, and institutions justify their climate policies or lack thereof.


COP30: Solutions on the Amazon Frontline


The upcoming COP30 UN Climate Summit, scheduled for November 10–21, 2025, will take place in Belém, Brazil. The summit is being branded as a “Summit of Solutions” with a focus on:

  • Indigenous rights and biodiversity

  • Expansion of climate finance mechanisms

  • Reinforcement of the 1.5°C target under the Paris Agreement

However, the conference has drawn controversy due to extreme accommodation costs in Belém. The UN held emergency talks with Brazilian officials in July to address price hikes, which risk excluding civil society and smaller nations from full participation.


Climate & SDG Convergence


Earlier this year, the Sixth Global Conference on Climate and the SDGs convened in Copenhagen, emphasizing the need to integrate sustainable development goals (SDGs) directly into national climate finance plans. One outcome was a call for finance ministries worldwide to apply joint budgeting mechanisms for climate and development, a shift from treating these priorities as separate issues.


The conference revealed that only 23 out of 173 updated Nationally Determined Contributions (NDCs) explicitly align climate targets with the SDGs, despite over 80% of the SDG targets being linked to climate outcomes. Speakers stressed that aligning national budgets and policies with both agendas is critical for maximizing impact. The event promoted nature-based solutions, cross-sector collaboration, and inclusive transitions that center people, ecosystems, and local knowledge.

Education as a Climate Solution


The UN also continues to elevate education as a strategic climate solution. The Global Education Coalition, supported by UNESCO and over 230 partners, has accelerated national digital education strategies across 50 countries. Meanwhile, initiatives like the Greening Education Partnership are embedding climate literacy into school curricula and teacher training.


The Coalition’s 2025 strategy places added emphasis on:

  • Gender equality in STEM,

  • Cross-border digital infrastructure, and

  • Early education on sustainability.


Information Integrity in Climate Communication


Misinformation remains a persistent challenge. To combat this, the UN launched a Global Climate Information Integrity Initiative, emphasizing transparency in climate science communication. A new platform called “Verified for Climate” aims to elevate science-based content across public campaigns, especially ahead of COP30.


A Future-Oriented Framework


With COP31's hosting bid still undecided between Turkey and Australia, and the ICJ’s ruling still reverberating across legal and political sectors, the remainder of 2025 promises additional shifts in how climate governance is operationalized. The growing overlap between environmental law, youth empowerment, and international education signals a new era in multilateral policy: one where education and ecological justice are tightly interwoven.
