As climate-related disasters escalate around the world— rising seas, deadly heatwaves, floods, and droughts—the urgency of coordinated international climate action has never been clearer. In this context, the 30th Conference of the Parties (COP 30) to the United Nations Framework Convention on Climate Change (UNFCCC) will convene this November in Belém, Brazil, a gateway to the Amazon rainforest and a symbol of the stakes at hand. 

First, Mark Lutes provides a roadmap for what to expect at COP 30, highlighting five critical areas where progress—or failure—will shape the future of the global climate regime: closing the ambition gap in national climate commitments, protecting forests and biodiversity, accelerating a just transition away from fossil fuels, delivering on promises of adaptation finance, and advancing a new global roadmap for scaling climate finance to at least $1.3 trillion annually. 

Next, Supraja Kumar examines recent progress within the International Civil Aviation Organization (ICAO), focusing on the adoption of an updated carbon dioxide standard for aircraft. While ICAO's new standard represents incremental progress in fuel efficiency, Kumar explains that deep decarbonization of aviation will require more than modest technical improvements—it will demand systemic changes, including a rapid shift to sustainable aviation fuels and the deployment of zero-emission aircraft. 

Third, Serkan Ünalan and I provide a critical assessment of the International Maritime Organization's (IMO) recently approved Net-Zero Framework. We caution that flaws in greenhouse gas accounting rules for marine fuels could allow the shipping sector to meet compliance targets while continuing to use fuels that exacerbate climate change, such as biofuels made from food-based feedstocks like soy and palm oil. We call for urgent corrections to ensure that the IMO's framework closes key loopholes, including accounting for indirect land-use change from biofuels, methane slip from LNG engines, and nitrous oxide emissions from ammonia-fueled ships. 

Thomas Brewer concludes the issue with a timely exploration of how sea level rise is interacting with solid waste management practices, particularly in Western Europe. Brewer illustrates how coastal vulnerability to rising seas varies greatly by location and governance context, with examples from Amsterdam, Hamburg, and Copenhagen showing how cities are adapting waste management infrastructure and policies to meet these challenges. Brewer emphasizes that the accelerating pace of sea level rise wi l require multi-level governance responses to handle waste. As climate impacts intensify and the window for meaningful mitigation narrows, international climate policy is entering a decisive phase. The articles in this issue underscore that achieving the goals of the Paris Agreement will require not only bold national commitments at COP 30, but also sustained progress in key global sectors, from aviation and shipping to waste management. The success of COP 30 and associated international frameworks will depend on a shared commitment to move beyond incrementalism and deliver real, measurable progress.
