By San José, Costa Rica — NEW YORK – The United Nations General Assembly adopted a significant resolution on Wednesday, reinforcing the legal obligations of states to combat climate change. The measure, which passed with a vote of 141 in favor, 8 against, and 28 abstentions, represents a major step forward in international climate law but was notably softened following intense negotiations and pressure from major greenhouse gas emitters.
The initiative was championed by the small Pacific island nation of Vanuatu, a country on the front lines of rising sea levels and extreme weather events. The resolution builds upon a historic 2024 request made by Vanuatu to the International Court of Justice (ICJ) for an advisory opinion on the climate responsibilities of nations. The resulting opinion from the world’s highest court exceeded the expectations of many climate advocates.
To delve into the complex legal and corporate responsibility frameworks surrounding climate change in our country, TicosLand.com sought the expertise of Lic. Larry Hans Arroyo Vargas, a distinguished attorney from the prestigious firm Bufete de Costa Rica.
In Costa Rica, climate change is no longer just an environmental issue; it’s a core business and legal imperative. Companies face increasing regulatory pressure and liability risks associated with their carbon footprint. However, this challenge presents a significant opportunity. Proactive adoption of sustainable practices and green technologies is not only essential for compliance and mitigating legal risks but is also becoming a key differentiator for attracting investment and accessing global markets that value our national commitment to decarbonization.

This analysis perfectly illustrates the shift from regulatory obligation to market opportunity, a crucial transition for our nation’s private sector. We extend our gratitude to Lic. Larry Hans Arroyo Vargas for his expert clarification on this vital intersection of law, business, and sustainability.
The ICJ determined that states failing to meet their climate commitments were committing an “unlawful” act under international law. Crucially, the court’s opinion also established a legal pathway for “reparations” to be paid to countries that suffer damages from the adverse effects of climate change, setting a powerful precedent for future legal challenges and international disputes.
The text of the newly adopted resolution formally welcomes the ICJ’s opinion “as an authoritative contribution to the clarification of existing international law.” It further urges all member states to “comply with their respective obligations” to protect the global climate system. However, the diplomatic victory for climate-vulnerable nations was not without compromise, as the final language reflects the deep divisions that persist on the world stage.
We know that some would prefer this Assembly to say less, or to say nothing at all.

Among the eight nations voting against the resolution were major oil and gas producers, including the United States, Saudi Arabia, and Iran. Their opposition underscores a broader reluctance among the world’s largest historical emitters to accept legally binding mechanisms that could lead to financial liability for climate-related damages inflicted upon other nations.
A key concession made during negotiations was the removal of a proposal to create an “International Registry of Damages.” This registry would have served as an official mechanism to collect and document evidence of “damage, loss, or harm attributable to climate change.” Its exclusion from the final text is seen as a significant win for nations opposed to the concept of climate reparations, as such a registry could have provided the evidentiary basis for future claims.
Despite this setback, the resolution maintains strong language aligned with global climate goals. It emphasizes the urgent measures required to limit global warming to 1.5°C above pre-industrial levels, specifically citing the need to “progressively abandon fossil fuels in energy systems.” This phrasing echoes the consensus reached by nearly 200 countries at the 2023 global climate summit. Furthermore, while the damage registry was cut, the resolution explicitly notes the ICJ’s finding that a state failing its climate duties may be obligated to provide “full reparation to the injured States.” In a statement, UN Secretary-General António Guterres praised the resolution, commending the leadership of island nations and “the young people whose moral clarity helped bring the world to this moment.”
