十多年来,联合国环境署《排放差距报告》每年都对“2030年温室气体预测排放量”与“为避免气候变化最严重影响所规定的排放量”之间的差异进行审查。
今年的报告有哪些新发现?
报告发现,尽管2019冠状病毒病(COVID-19)大流行导致二氧化碳排放量出现短暂下降,但世界仍然朝着截至本世纪末升温超过3°C的方向发展,远远超出了《巴黎协定》所规定的“将全球升温幅度控制在2°C内,并致力于实现1.5°C温控目标”的水平。
但是,在已有政策的基础上,2019冠状病毒病(COVID-19)疫情后的低碳复苏可能会使2030年预计温室气体排放量减少25%。这远远超出实施《巴黎协定》无条件国家自主贡献所能预见的减排量,大大增加了世界实现2°C温控目标的机会。
报告还分析了迄今为止的低碳复苏措施,总结了各国出台的最新净零排放承诺,并探讨了生活方式、航空和航运部门填补这一差距的潜力。
Despite a dip in greenhouse gas emissions from the COVID-19 economic slowdown, the world is still heading for a catastrophic temperature rise above 3°C this century – far beyond the goals of the Paris Agreement. But UNEP's Emissions Gap points to hope in a green pandemic recovery and growing commitments to net-zero emissions.
Join us on Wednesday 9 December for the launch of the Emissions Gap Report 2020.
Every year, the Emissions Gap Report signals the difference between where greenhouse emissions are predicted to be in 2030 and where they should be to avoid the worst impacts of climate change.
