After two weeks of intense negotiations, the 2025 UN Climate Change Conference (COP30) in Belem, Brazil, concluded with a major multilateral deal. Nearly 195 countries adopted the “Belem Package,” a comprehensive set of 29 decisions covering climate finance, just transition, adaptation, gender and technology.
The centerpiece of the agreement was a bold commitment to mobilize $1.3 trillion annually by 2035 for climate action. Adaptation finance, financial support for developing countries to adapt to climate change impacts such as extreme weather events and rising sea levels, is set to double in 2025 and triple by 2035, according to the package. Crucially, the long-awaited Loss & Damage Fund—created in previous COPs—was operationalized, with clear replenishment cycles agreed upon.
AP Human Geography teacher Brent Keemle said the agreement highlights long-standing disparities between nations. “These types of agreements could impact global inequality in the sense that highly developed countries produce most of the carbon emissions that are connected to increased global temperatures,” Keemle said. He added that developing countries often lack the resources to address climate-related harms such as drought and extreme weather, and that if funding commitments are fulfilled, “these packages would allow developing countries to meet challenges that could be devastating for fragile economies.”
To help countries turn their climate pledges into real action, COP30 launched two major initiatives: the Global Implementation Accelerator and the Belem Mission to 1.5 °C. Both initiatives were designed for the implementation of national climate and adaptation plans. For the first time, the conference also explicitly addressed climate disinformation; parties committed to promoting information integrity and countering false climate narratives.
Keemle also pointed to broader social effects tied to climate policy outcomes. “If funding is provided and areas affected by climate change are able to mitigate the challenges it brings, it could reduce the number of migrants fleeing environmental disasters,” he said, explaining that people may choose to remain in their home regions if infrastructure can withstand climate-related issues.
Belem also delivered on equity and social justice. Delegates approved a just-transition mechanism that emphasizes support to workers, Indigenous communities and marginalized groups through technical cooperation and capacity building. The Gender Action Plan was strengthened, requiring gender-responsive budgeting and greater representation of Indigenous, rural and Afro-descendant women in climate roles.
In a major boost to forest protection, parties signaled their support for nature-based solutions. The COP30 Action Agenda included the launch of the Tropical Forests Forever Facility, which raised $5.5 billion and involved more than 50 countries. At least 20% of that funding is earmarked for Indigenous peoples and traditional communities.
Public health was not left behind. The Belem Heath Action Plan, endorsed by more than 30 countries and, backed by the World Health Organization, secured $300 million to strengthen climate-resilient health systems, disease surveillance and climate-informed health policies.
Notably, however, the final COP30 agreement did not include a clear roadmap to phase out fossil fuels. While more than 80 countries had backed a stronger withdrawal from fossil fuels, the text ultimately referred only to a “transition away” from fossil fuels—echoing the language of a prior COP30 decision rather than establishing a firm exit plan.
AP Environmental Science teacher Zachary Marotta said the outcome reflects both progress and unresolved challenges. “They have a vision and goals for 10 years from now, which is progress,” Marotta said, noting that many countries, including the United States, remain heavily dependent on fossil fuels and that an immediate phase-out would be difficult. He expressed hope that future meetings would continue to build on the progress made at COP30.
Even in Iowa, thousands of miles from Belem, the outcomes of COP30 could have meaningful effects. The tripled adaptation finance could influence U.S. and state-level investments in flood control, soil conservation and climate-resilient agriculture—areas especially relevant to Iowa farmers, who face growing risks from more extreme rainfall and flooding. Meanwhile, the just-transition mechanism and the global push for sustainable energy could shape the future of Iowa’s biofuels industry, potentially channeling more funding and innovation toward low-carbon energy in the Midwest.
Marotta also addressed how international climate efforts may translate domestically. He noted that the U.S. federal government did not send representatives to the conference, though some state officials attended. “Each part of the US is being hit differently by climate change,” Marotta said, adding that states will need to adapt based on their own challenges.
Turning to Iowa, Marotta emphasized land use as a key area of focus. He said that finding more sustainable ways to use land, reclaiming previously used land, and protecting the small percentage of non-altered land are among the most effective ways Iowa can make positive environmental changes.
Ultimately, COP30 in Belem was framed by its organizers as a “COP of implementation”—a turning point meant to move climate diplomacy from promises to real, on-the-ground action. While the lack of a firm fossil fuel exit disappointed some, the sweeping financial commitments and institutional mechanisms created in Belem lay the groundwork for an ambitious next chapter in global climate cooperation.
