Sustainable development is proposed by human beings on the basis of summing up experience and lessons in the face of the increasing destruction of the earth on which human beings rely for survival. It is a reflection of human beings' production and living activities, as well as their understanding of the realities and future concerns. What is sustainable development? In English development It is development that meets the needs of the present without compromising the ability of future generations to meet their own needs (development that meets the needs of the present without compromising the ability of future generations to meet their own needs).Sustainable development is not about a certain country, region, industry, unit or product. The harmonious coexistence between man and nature is the prerequisite for sustainable development, and only development under this premise is sustainable. In order to achieve sustainable development, the main problems we are facing at present are global climate change, loss of biodiversity, depletion of stratospheric ozone, shortage of water resources and deterioration of water quality, and acid deposition. The United Nations Intergovernmental Panel on Climate Change (IPCC) released the sixth assessment report of the Intergovernmental Panel on Climate Change (IPCC) in Interlaken, Switzerland, with the comprehensive report "Climate Change 2023" (AR6 Synthesis Report: Climate Change 2023).The report clearly states that "there is no doubt that human influence is the fundamental cause of the warming of the atmosphere, oceans, and land. ".Environmental issues have become major opportunities and challenges that must be faced in global business activities. At present, from the perspective of business operation, enterprises mainly improve their sustainable development capabilities through the following aspects: 1. Improving the productivity of natural resources with the help of advanced technology;2. The production mode should be developed towards the direction of the biological chain, and the "closed loop" production process should be implemented to avoid waste and pollution;3. Change the traditional business model and use lean manufacturing and management to promote sustainable development of enterprises; Reinvest in natural resources to restore, maintain, and expand life on our planet.

With the improvement of urbanization construction, people's demand and consumption of energy are also increasing day by day. Fossil energy (oil, coal, natural gas, etc.) accounts for 85% of total energy consumption. The extensive use of fossil energy has led to a surge in greenhouse gases (CO2, CH4, O3), which has seriously disrupted the balance of the climate and caused environmental problems such as ecological pollution and resource shortages. Although the widespread use of air conditioning, refrigerators and other refrigeration equipment can alleviate the problem of high temperatures, these traditional refrigeration facilities rely on vapor compression to achieve cooling, which not only consumes electrical energy but also exacerbates global warming through the use of refrigerants (such as hydrofluorocarbons), further causing serious harm to the environment. Therefore, solving energy consumption and environmental change are two major problems facing us at present, and it is urgent for people to make response strategies as soon as possible and explore a green and low-carbon cooling method .Research shows that 39% of the country's total energy consumption is used in buildings, of which 60% is used for space heating and cooling. If this rate continues to develop, by 2050, the energy consumption for building cooling will increase tenfold. Therefore, reducing energy consumption for indoor temperature regulation is important for alleviating environmental problems. The "radiation cooling" technology has attracted attention due to its ability to achieve cooling without any energy input, and is expected to replace traditional cooling methods. Radiative cooling is a technology that achieves cooling through spectral regulation. Compared to traditional active cooling technologies, this passive technology does not consume additional electrical energy and can be applied to the exterior surfaces of various buildings and structures. Therefore, it is considered an emerging technology that can reduce carbon emissions from air conditioning and refrigeration.
