Abstract
Climate change is globally recognized as a long-term systemic risk faced by human beings. The impact range and depth of global warming caused by human activities are gradually increasing. "Carbon Peak" and "Carbon Neutral" are climate commitments to reduce the expected global warming. In the global context, mankind is facing major ecological and environmental threats. To actively tackle climate change, China has committed to achieving the peak of carbon dioxide emissions by 2030 and achieving carbon neutrality by 2060.At present, China has decomposed carbon emission reduction targets from top to bottom, and each urban has put forward corresponding strategies based on the actual situation of its own region, so as to achieve low-carbon transformation and development throughout the country. We will review the policies and practices of each urban, and work from two aspects, namely energy revolution action and spatial planning reform, to build "Carbon Neutral" urbans by reducing carbon emissions and increasing carbon sinks. On the one hand, in terms of energy revolution, the troika will work together to carry out the following practical work: first, plan emission quotas and carbon peak schedule in key areas in advance to guide and strengthen market expectations, such as industrial areas including cement, steel, electric power, chemical industry, etc., and people's livelihood areas such as construction, transportation, etc.; Second, continue to promote the revolution in energy supply, continue to vigorously promote the low-carbon transformation of the energy system, and further accelerate the development of renewable energy and the deployment of storage and transportation facilities; Third, we will accelerate the spread of advanced energy-saving and emission-reduction technologies and tap the potential of energy conservation and efficiency improvement. On the other hand, in terms of spatial planning reform, in order to enhance the carbon sequestration capacity of the ecosystem, reduce urban carbon emissions, and improve the modernization of national governance capacity, China starts from the following four aspects: First, we reformed the spatial planning system from urban planning system to land spatial planning system, optimized the land spatial pattern, and increased the carbon sink through the green infrastructure protection and control planning strategy of forest land, cultivated land, wetland and other natural protected areas, and actively supported the carbon neutral strategy; Second, improve the compact urban spatial layout, create a comfortable living circle with appropriate scale, compact space and rich functions, low-carbon travel, reduce unnecessary commuting caused by seeking life services, and reduce the carbon emissions of urban commuting; Third, focus on power decarbonization and smart energy supply, optimize the structure and supply strategy of water resources, realize the recycling of waste resources, and establish an efficient, clean and low-carbon municipal facilities system; Fourth, from industrial structure, low carbon technology, spatial layout, carbon sink capacity and other aspects of the industrial system to promote carbon emissions peak. China's proposed from “Carbon Peak” to “Carbon Neutral”, carbon transition only 30 years, while developed countries need to 60 years to 70 years, is a very powerful positive goals, means from the development mode to the sources of energy, industry, infrastructure, space planning, and even the trade and consumption, China will conduct systematic structural change, transformation and innovation. China's move to a low-carbon development model that is carbon neutral and adaptable to climate change can make an important contribution to boosting global confidence in climate action.
