Green Construction: Status and Prospects of Shenzhen Construction Industry’s “Double Carbon” Goal

Shenzhen has extensive green construction experience as one of China’s new green development pilot cities.Shenzhen has experienced substantial economic growth as a result of the reform and opening up,but it has also had to face the burden of urbanization problems and difficulties.This article looks at the history of green construction in Shenzhen and how the spirit of the city influenced it.The work then divides the procedure into two phases and examines the issues that arise.Suggestions for achieving the“Double Carbon”aim in the building industry are sought through this effort.

Design Method and Classic Case Analysis of Low Carbon Community

Realizing “carbon peaking” and “carbon neutrality” is a major strategic decision made by China to coordinate domestic and international situations.In order to achieve the “double carbon” goal,it is also necessary for relevant practitioners to actively put into practice to improve the participation of residents and advocate low carbon life while formulating the policy action plan.Community is an important place for human activities and one of the main spatial types of carbon emissions in cities.Doing a good job in planning energy conservation and emission reduction in the community plays an important role in achieving the “double carbon” goal.Through the analysis of classic low carbon community practice cases at home and abroad,6 planning and design methods for low carbon community are concluded,and the development status of low carbon community in China is reflected and summarized.

Carbon Emission Measurement and the Decoupling Effect Under the“Double Carbon”Goal in Xi’an,China

Cities generate more than 60%of carbon emissions and are the main battleground for achieving the target.However,there is no unified and standardized measurement methods of carbon emissions in cities.In this paper,we took Xi’an as an example and started by measuring carbon emissions with the new standards.Then,the decoupling of economic development from carbon emissions was studied according to the Tapio decoupling theory.Based on the generalized Divisia index method,the decoupling effort model was proposed to study the impact of carbon emission factors contributing to carbon reduction.The results show:(i)During the period 1995–2021,the carbon emissions of Xi’an increased rapidly,with an average annual growth rate of 6.06%,due to the accelerating pace of urbanization and industrialization.(ii)The energy consumption sector accounted for the largest share of carbon emissions,ranging from 77.38%to 89.46%.Xi’an’s energy structure is primarily based on fossil fuels,especially coal,which holds a significant proportion.To achieve the“double carbon”goal,it is crucial to reduce the dependence on fossil fuels.(iii)The 10th Five-Year Plan was in the state of“expansive coupling”,while other periods were in the“weak decoupling”state from the 9th to 14th Five-Year Plan periods.After the carbon peak year in the 15th Five-Year Plan,it would be in a state of“strong decoupling”.The agricultural production account was the first to achieve a“strong decoupling”state.(iv)The government of Xi’an made efforts to decouple,but these were not enough.Technological innovation played a crucial role in the carbon reduction of Xi’an,and was a key factor in achieving the“double carbon”goal.
