新冠疫情使全球碳排放减少（图）
新冠疫情 全球 碳排放 减少
2020/5/21
《自然—气候变化》5月19日发表的一篇论文指出，由于政府采取防止新冠肺炎疫情传播的政策，截至2020年4月初，全球二氧化碳日排放量比2019年的平均水平下降了17%。目前，各国政府实施的防止新冠肺炎传播的政策对全球能源需求产生了巨大冲击。随着世界各地大量人口被要求待在家中、关闭边境，消费率和运输率都相应下降。不过，全球实时排放数据的缺失增加了量化这种冲击的难度。

新技术使垃圾化身石墨烯
新技术 垃圾 石墨烯
2020/2/10
近日，美国莱斯大学研究人员在《自然》上报道，他们可以将从食物残渣到汽车旧轮胎的任何含碳固体转化成石墨烯。如今，从高强度塑料到柔性电子产品，由石墨烯制成的材料使用范围十分广泛。现有技术只能生产极少量的“完美”石墨烯，而在实验室里，这种新方法已经可以每天生产出几克近乎原始的石墨烯，研究人员现在正在扩大其产能至每天数公斤。

丹麦蓝天清洁技术助力减缓农业气候影响
丹麦 蓝天清洁技术 减缓影响 农业气候
2019/8/28
农业、航空是重要的温室气体排放源，随着全球应对气候危机的日趋紧迫，必须找到全新的解决方案才能确保全球变暖不超过1.5°C。丹麦技术大学和奥胡斯大学的研发人员近来成功开发出了蓝天清洁（SkyClean）技术，该技术不仅可以将农业的气候影响减半（可以减少50％的农业温室气体排放），还可以将秸秆和污泥转化为气候中性的航空燃料，为应对气候变化提供全新的重要解决方案。

日本提出二氧化碳零排放目标
日本 二氧化碳 零排放
2019/6/6
据《日本经济新闻》报道，日本政府提出2070年前后二氧化碳排放量将降至零。这一新目标明确提出将利用可再生能源和核能，并使用低成本制造氢气技术和二氧化碳回收再利用技术。此举使日本成为七大工业国（G7）中第一个提出二氧化碳零排放的国家。日本政府计划6月份将此次提出的目标提交给联合国，同时在G20峰会上公布。因受到2011年福岛第1核电站事故影响，核电站停运，二氧化碳减排受到影响。日本政府认为有必要提出...
