More than 50 nations attend world-first conference on phasing out fossil fuels

Fossil fuel phaseout talks just crossed a real threshold: for the first time, more than 50 nations sat down together specifically to plan a way off coal, oil, and gas. The two-day gathering in Santa Marta, Colombia, brought together an unusually wide mix — major producers like Australia, Norway, and Canada alongside Pacific island nations like Tuvalu and Vanuatu, with Europe and emerging economies in between. No binding deals were expected, but the recommendations will feed into a voluntary roadmap being shaped under Brazil’s COP30 leadership. It’s a small, hopeful shift: producers and consumers finally talking openly about a transition that, until recently, was almost taboo to name out loud.

Ten nations pledge €11 billion for a 100GW North Sea wind hub

North Sea wind hub: Ten European nations have pledged €11 billion to build a 100-gigawatt offshore wind network in the North Sea, enough clean electricity to power roughly 100 million homes. The commitment, formalized through the Esbjerg Declaration, is the largest coordinated offshore wind investment in European history. Beyond the raw numbers, the agreement marks a fundamental shift from competing national energy projects toward a shared multinational grid spanning northwestern Europe. It directly addresses Europe’s dependence on imported fossil fuels while setting ambitious targets of 100GW by 2030 and 300GW by 2050.

The high seas treaty enters into force, giving two-thirds of the ocean its first legal protection

The High Seas Treaty entered into force on January 17, 2026, giving the roughly two-thirds of the ocean beyond national borders binding legal protection for the first time in history. After nearly 20 years of negotiations, 60 nations ratified the agreement by September 2025, triggering its historic implementation. The treaty empowers the international community to establish marine protected areas in international waters, require environmental impact assessments for deep-sea activities, and share the benefits of marine genetic resources equitably among all nations. What once had no legal guardian now does.

Australia to invest $125m in Pacific island off-grid and community scale renewables

The funding, which comprises a $75 million investment through the REnew Pacific program and $50 million through the Australia-Pacific Partnership for Energy Transition, was announced at the COP29 United Nations climate summit. The REnew Pacific program will help deliver off-grid and community-scale renewable energy in remote and rural parts of the Pacific, enabling lighting, access to water, improved agriculture, better food security, quality education and health services, reliable communications connectivity and enhanced incomes. The $50 million Partnership for Energy Transition funding will capture renewable energy investment benefits such as energy transition modelling, grid studies, feasibility studies and university collaborations.

Spain to give Ukraine €1 billion in military aid in decade-long defense deal

Although the precise details of the agreement have not been made public, the Spanish government said its assistance would “allow Ukraine to prioritize its capacities, including its air defenses.” The bilateral deal was agreed two days after Russia’s onslaught in the north-eastern Ukrainian city of Kharkiv killed 18 people, and as E.U. leaders grow increasingly exasperated with Hungary’s efforts to block aid to Ukraine.
