At this stage，green，low-carbon and sustainable development has become the general trend of global development. The “double carbon” target strategy proposed by General Secretary Xi Jinping is not only the internal requirement for China to achieve high-quality development，but also the inevitable choice to conform to the global development trend and build a community of human destiny. In 2022，Beijing will host the Winter Olympics and Paralympics. We must strive to start from the four aspects of construction，energy，transportation and carbon sequestration，give full play to the advantages of green energy，artificial intelligence，5G and other cutting-edge technologies，and realize low-carbon hosting，thereby helping Beijing Green development，driving the growth of green technology and industry in the Beijing-Tianjin-Hebei region，and contributing to the country’s goal of achieving carbon peak and carbon neutrality.
