腾讯与TED在伦敦气候周公布“碳寻计划”二期终选结果：10项前沿低碳技术从660余个全球项目中胜出，获约1.7亿元中试资助；另有6项创新技术获得支持。入选团队进行分享，并与专家、投资方共议气候科技行动。
中国科学院上海高等研究院发布全球首个全景式碳排放核算系统“磐石·禹衡碳核算大模型”，实现从“跟跑”到“重构范式”的技术突破。该系统通过数据、算法、算力三位一体，破解传统碳核算知识壁垒高、数据更新慢、分辨率低等瓶颈，构建坚实底层支撑体系。
生成式AI工具将文本转为图像和视频时，碳足迹远超预期。Hugging Face研究发现，视频生成能耗随长度激增：六秒视频耗能是三秒视频的四倍，揭示当前技术能效低下，需关注环保影响。
OpenAI在挪威纳尔维克建立欧洲首个AI数据中心"Stargate Norway"，这是其全球布局的重要一步。该数据中心采用可再生能源供电，初期容量230兆瓦，计划2026年前部署10万块NVIDIA GPU。项目采用液冷技术提高能效，并回收余热支持低碳企业。OpenAI将优先为挪威初创企业提供计算资源，同时向欧洲其他地区开放剩余算力。此举旨在推动欧洲AI创新，配合挪威政府的主权AI战略，延续了OpenAI近期在欧洲的扩张步伐。
