With the issue of climate change increasingly restricting the sustainable development of society, people must realize that we must control atmospheric concentrations of greenhouse gases at a certain level. However, the traditional model of economic development will lead to human demand for energy continuing to grow, followed by a growth in emissions of carbon dioxide. Obviously we must ensure that there is rapid economic development, but also to protect the human living environment, which is a very sharp contradiction. A good solution to this conflict is to take a new model of development --- a low-carbon economy. The so-called low-carbon economy refers to the reduction of greenhouse gas emissions, the application of new technologies, new materials and new practices, etc., through improvements, optimization or innovative production and business activities, to achieve the maximum degree of reduction of greenhouse gas emissions, and the formation of a new economic development model, the goal is to mitigate climate change and promote sustainable human development. On how to develop a low-carbon economy, domestic and foreign scholars have been studied from many angles, one of which is a consensus to reduce greenhouse gas emissions through the development and use of low-carbon technologies. 展开更多
