28. 国际标准，如国际电联制定的标准，为各国及城市、信通技术部门和其他利益攸关方实现更好、更环保重建提供了精准工具。国际电联的一项绿色标准为信通技术部门制定世界上第一个信通技术部门特定的基于科学的目标提供了必要的指导，并得到基于科学的目标倡议的批准，以根据《巴黎协定》和可持续发展目标实现净零。此外，为了提高整个信通技术价值链的可持续性绩效，国际电联制定了直接支持信通技术部门向循环经济模式过渡的技术标准。31 国际电联的绿色标准为开发信通技术设备的通用电源适配器和充电器解决方案提供了规范和要求。2022 年，国际电联向全球 10 个国家提供技术援助，支持制定电子废物监管法规。国际电联还与世界经济论坛合作，开发电子废物管理政策做法工具包，为如何根据生产者延伸责任原则制定国家电子废物政策和条例提供指导。
28. International standards such as those developed by ITU have provided countries, cities, the ICT sector and other stakeholders with the exact tools they need to build back better and greener. One of the ITU green standards has provided the ICT sector with the guidance it needs to set the world’s first ICT sector-specific science-based targets, approved by the science-based target initiative, to reach net zero in line with the Paris Agreement and the Sustainable Development Goals. Furthermore, to improve the sustainability performance of the entire ICT value chain, ITU has developed technical standards that directly support the transition of the ICT sector towards the circular economy model.31 The green standards of ITU have provided the specifications and requirements for developing a universal power adapter and charger solution for ICT devices. In 2022, ITU has been providing technical assistance to 10 countries globally by supporting them with their e-waste regulation. In collaboration with the World Economic Forum, ITU also developed a toolkit on policy practices for e-waste management, which provides guidance on how to develop national e-waste policies and regulations based on the principle of extended producer responsibility.
