International public finance for climate adaptation in developing countries reached US$28.2–31.7 billion in 2024, increasing by US$1 billion from the previous year.
±«±··¡±Ê’s highlights the growing financing gap for climate adaptation and loss and damage, as vulnerable countries struggle to access sufficient support. Despite these challenges, increased multilateral development bank financing, South-South cooperation and private sector investment offer positive signs for strengthening global adaptation efforts.
Climate change may accelerate antimicrobial resistance by helping drug-resistant microbes emerge, spread and multiply, increasing global health risks and threatening effective infection treatments.
As the world heads towards exceeding 1.5°C of warming, adaptation efforts are not keeping pace with accelerating climate impacts, leaving vulnerable communities exposed to climate risks. The found that developing countries will need an estimated US$305 billion annually by 2035 for climate resilience measures, while international public adaptation finance reached just US$28.2–31.7 billion in 2024. Ahead of COP31, the report underscores the urgent need to scale up finance for climate adaptation, strengthen institutions and speed up action to build resilience and protect communities.
The window to limit warming to 1.5°C without significant overshoot has closed, but Ä¢¹½ÊÓƵEP says rapid cuts can still avert worse climate impacts.
Against a backdrop of intensifying climate impacts and geopolitical tensions, the new examines the gap between current efforts to cut emissions and the action needed to meet the Paris Agreement's long-term temperature goal. While the clean energy transition is accelerating due to lower costs and concerns over energy security, affordability, and industrial competitiveness, global action remains insufficient to avoid the worst risks of climate change. "And the world is running out of time and excuses to close it," said the Ä¢¹½ÊÓƵ Secretary-General, calling on governments to take action.
Reducing food loss and waste can fight hunger and climate change by improving food security, cutting emissions, and strengthening sustainable food systems.
The , adopted on 16 September 1987, unites nations to protect the ozone layer by phasing out harmful chemicals and advancing climate action.
Air pollution involves complex pollutants, sources, chemical reactions, measurement standards, and health impacts, making clean air far more technical than it appears.
A new finds that every US$1 invested in tackling climate change and air pollution together could generate around US$15 in economic benefits. Cleaner air can cut healthcare costs, boost productivity and save lives, while also slowing global warming. In 2025, human-caused outdoor air pollution was linked to 6.4 million premature deaths worldwide. The report identifies 25 proven measures across energy, transport, agriculture, homes and waste, warning that every year of delay could cost the world more than US$1.5 trillion in lost benefits.
The world is likely to cross the 1.5°C global warming threshold within the next few years, increasing the risks of extreme weather, ecosystem loss and damage to health, food and water supplies. A new says the best remaining path is to keep this rise as small and brief as possible, then bring temperatures back below 1.5°C. This requires rapid and sustained cuts in greenhouse gas emissions, a faster shift from fossil fuels to renewable energy, stronger climate adaptation and carefully managed removal of carbon from the atmosphere. Every fraction of a degree — and every year above 1.5°C — matters.
The global energy system powers almost everything we do, but it is also fuelling some of the planet’s biggest challenges. ±«±··¡±Ê’s says transforming the system means rapidly expanding renewable energy, improving energy efficiency and redirecting fossil fuel subsidies towards clean, affordable power. But the transition must also protect people and nature, including communities affected by mining for renewable-energy minerals. Expanding grids, local renewable systems and clean cooking can widen energy access. With political will, a cleaner energy system can also be fairer and more resilient.
Once considered one of the world’s fastest-disappearing ecosystems, mangrove forests are showing remarkable signs of recovery. A recent global study using satellite imagery from the 1980s to 2023 found that global mangrove losses have slowed sharply, while natural regeneration and expansion are increasingly offsetting past declines. These coastal forests protect shorelines, store carbon, support fisheries and provide habitat for more than . Ä¢¹½ÊÓƵ Environment Programme () and partners are helping drive this recovery through science-based, community-led restoration efforts in countries including Kenya, Costa Rica, Benin and across the South China Sea region, combining conservation, sustainable livelihoods and innovative financing.
The Moon has fascinated humanity for millennia and plays a vital role in sustaining life on Earth through its influence on tides and ecosystems. As lunar exploration accelerates, with countries and private companies pursuing ambitious missions, the United Nations is emphasizing the need for sustainable space activities. Despite international treaties and guidelines, an estimated 140 million pieces of space debris orbit Earth, including defunct satellites, rocket bodies, collision fragments and mission-related debris. These objects can damage spacecraft, pollute the atmosphere during re-entry and even pose risks to people and ecosystems. The and the are working to address these growing environmental challenges through stronger global cooperation and governance.
The 2026 World Cup demonstrated that mega-sporting events could leave cities greener, not just busier. Toronto, Seattle and Mexico City turned tournament pressure into long-term environmental gains through net-zero facilities, restored parks, native tree planting, reusable foodware, food rescue and stronger recycling systems. Expanded public transit, cycling routes and walkable streets also helped fans choose lower-carbon travel. The tournament showed that when cities paired major events with community action and lasting partnerships, the final whistle marked the beginning of a healthier, more sustainable urban future.
