《巴黎协定》将努力控制全球温度到2100年不超过工业化前1.5℃确定为全球温控目标之一。科学研究表明，如果将全球温升控制在1.5℃范围内，那么地球各系统要承受的气候风险会远低于2℃。当然相比于2℃目标，1.5℃目标对全球气候变化减缓行动的要求更为严苛。尽管在《巴黎协定》中各缔约方承诺了各自到2030（2025）年的减排目标，但它们相对于实现1.5℃目标的减排力度而言仍有很大的不足。若想要实现这一目标，全球必须立即行动并采取强有力的减排、脱碳和固碳措施。1.5℃目标不仅是全球努力应对气候变化的方向，而且是开启未来世界低碳可持续发展的重要标志。
The Paris Agreement has set one of its targets that to make efforts to limit the temperature to increase 1.5℃ above pre-industrial levels（in short 1.5℃ target）. Comparing with 2℃ long term temperature goal，the 1.5℃ target will reduce the climate risks for the earth systems，but need more stringent global mitigation actions. Although the Parties had committed their national determined contributions till 2030（2025），there is still a big gap with respect to the 1.5℃ target. The global mitigation actions should be taken immediately to reduce emissions. Other actions related with decarbonization and carbon sequestration measures should also be conducted to reach this target. 1.5℃ target is more than just a direction，but an important indicator of starting to implement future low-carbon sustainable development.
