Abstract: |
Since the industrial revolution, the concentration of carbon dioxide and other greenhouse gases
in the atmosphere has increased significantly, and the continuous accumulation of greenhouse effect has
led to global warming, which further leads to frequent occurrence of extreme weather and natural disasters.
Thus, global climate change caused by greenhouse gas emissions has become a decisive issue threatening
the survival and security of human beings and the stability of the ecological environment in this era. China
has been the world’s largest carbon emitter since 2006, accounting for 27.9 percent of global emissions in
2019. China plays a pivotal and irreplaceable role in global efforts to reduce emissions and combat climate
change. President Xi Jinping has announced an ambitious climate target to have CO 2 emissions peak
before 2030 and achieve carbon neutrality before 2060 at the General Debate of the 75th Session of the UN
General Assembly. Moreover, to quest a preventive, low-cost and long-term carbon emission reduction
approach is the premise and guarantee of fulfilling China’s climate commitment.
China’s efforts to tackle climate change mainly rely on the use of clean energy or energy-
saving technology; technological progress contributed 60 percent to China’s 2017 reduction
in carbon emission intensity (based on 2005 data). However, the “rebound effect” and the
“Diminishing marginal effect” are the two insurmountable restraining factors in technological
progress, which limit the potential of technological development to reduce carbon emissions.
In this paper, it analyzed the incompleteness of China’s current carbon emission reduction
approach that took the technological progress as the core, and developed the concept of
“structural adjustment emission reduction”, as well as compared the main differences between
“structural adjustment approach to emission reduction” and “technological progress approach
to emission reduction”. As a conclusion, the irreplaceable carbon constraint role of spatial
planning as a leading means of structural adjustment emission reduction were highlighted.
Next, by defining the concept of spatial planning, this paper points out that urban and
rural land use is a coupling system of human economic development, social civilization
and ecological environment, and it is also an important spatial object for spatial planning
to coordinate and regulate human economic and social activities. The internal mechanism
of spatial planning for carbon emission reduction was analyzed from the perspective of
“spatial planning-land us-carbon emission”. It’s found that through four basic control means
of “boundary”, “function”, “location” and “index”, spatial planning influences the changes of scale, structure, layout and intensity of regional land use to optimize the social civilization forms and physical space entities associated with
carbon emissions, then improve the social efficiency, economic and ecological benefit in the region, and finally controlled the carbon emission
effects of the regional system.
Lastly, this paper argues that carbon emission reduction approach based on spatial planning is a process in which carbon emission constraint
thinking is applied to spatial planning analysis and scheme formulation, and carbon emission activities within a certain region can be actively
intervened. To provide specific pathway guidance for spatial planning to perform the functions of carbon emission constraint and promote
climate co-benefits, this paper constructs a carbon emission constraint framework of spatial planning based on a three-step approach, including
“determination of carbon emission regulators”, “calculation of carbon emission effects” and “development of carbon emission constraint
programs”. It is quite clear that the theoretical and practical research on spatial planning under the carbon emission constraint framework is still
in the exploratory stage, and it can focus on the following aspects in further research: 1) The tools of land use carbon emission effect assessment;
2) The correlation mechanism between planning elements and carbon emissions; 3) Cohesion and integration of carbon emission constraint
framework and planning system. |
