Over the past year, how is the carbon accounting evaluation in Tongzhou District?
"Facing the vision of carbon neutrality, we explore the deep integration of carbon emissions and carbon emission reduction related content with the detailed management and control of ecological environment, fully connect with relevant policies and plans of Tongzhou District and urban sub-centers, and carry out carbon emissions and emission intensity accounting for major projects and major projects." Cao Jingang, the Approval Section of the Ecological Environment Bureau of Tongzhou District, Beijing City, said.
On August 1, 2023, according to the "Notice of the Beijing City Ecological Environment Bureau on Trial Carrying out Carbon Emission Accounting and Evaluation in Environmental Impact Assessment of Construction Projects", the environmental impact assessment of construction projects in Tongzhou District of Beijing City carried out carbon emission accounting and evaluation on a trial basis. Over the past year, Tongzhou District has based on the application results of "carbon emission online" in zoning control and combined with the basic situation of construction projects, evaluated three construction projects, including the first phase of Beijing Rail Transit Line M101, based on carbon emission control goals, analyzed pollution reduction and carbon environmental protection measures and proposed carbon emission reduction measures and suggestions to promote in-depth and practical refined carbon emission management.
The carbon accounting evaluation of three projects is progressing smoothly
"According to requirements, Tongzhou District focused on the construction of environmental impact statements and demonstrated their application in road transportation, water conservancy, medical research and experimental development for the first time." Zhao Ji, the approval department of the Tongzhou District Ecological Environment Bureau of Beijing City, said that we have carried out exploratory research on the carbon emission level of Tongzhou District from the dimensions of time, industry, industry and other dimensions, clarified the goal of "carbon emissions online", put forward pollution reduction and carbon reduction management and control suggestions from the perspectives of energy, industry and management, and further clarified the management responsibilities of key carbon emission units.
According to reports, the three projects to carry out carbon accounting evaluation this time are: Beijing Rail Transit Line M101 Phase I Project, Beijing City Center for Disease Control and Prevention Biosafety Level III Laboratory Construction Project, Chaobai River Comprehensive Management and Ecological Restoration Project (Tongzhou Section). According to the characteristics of each project, the carbon accounting and evaluation work of the three projects has its own focus.
Among them, in the first phase of the Beijing Rail Transit Line M101 project, in accordance with the Beijing City local standard "Carbon Dioxide Emission Accounting and Reporting Requirements for Road Transport Industry," the focus is on "double control" management of the total amount and intensity of carbon emissions, and exploring the establishment of carbon accounting indicator systems and methods for rail transit activities.
"We guide the construction unit to calculate the total carbon emissions in the initial, medium and operation periods, analyze the carbon emission level, and propose carbon emission reduction measures in terms of source prevention and control, process control, and terminal management." Zhao Ji said.
In the construction project of the Biosafety Level 3 Laboratory of the Beijing City Center for Disease Control and Prevention, due to the lack of advanced values for the industry's carbon emission level, Tongzhou District has taken energy conservation, emission reduction and carbon reduction measures as the fundamental basis, and has adopted an all-out approach to reduce the carbon footprint to ensure energy-saving and low-carbon operation of the project, thereby truly realizing carbon emission reduction.
"Based on the experimental technical process, equipment models and equipment quantities of the project, we guide the construction unit to give priority to the use of advanced technology, reliable, energy-saving and consumption-reducing products, and make overall considerations from aspects such as process layout, public engineering system configuration, material transportation, etc., to build a ground source Heat pump system and energy management system to reduce the amount of fuel needed for heating during use, make every effort to reduce the carbon footprint and achieve carbon emission reduction." Zhao Ji said.
The Chaobai River Comprehensive Management and Ecological Restoration Project (Tongzhou Section) is a collaborative management project for the Chaobai River in the Beijing-Hebei section and an important starting point for promoting the coordinated development of Beijing, Tianjin and Hebei. In this project, Tongzhou District explored the coordinated management and control of carbon pollution in Beijing, Tianjin and Hebei to coordinate the promotion of regional low-carbon development and effectively improve the energy efficiency and environmental benefits during the construction and operation periods of river ecological management projects.
"On the one hand, we build a regional collaborative linkage system and build a work pattern for coordinated promotion of pollution reduction and carbon reduction. We refer to the pollution reduction and carbon reduction management and control requirements of Beisan County, and finally put forward optimization and adjustment suggestions and ecological and environmental impact mitigation measures to continuously deepen the three places. Collaborative cooperation in research on carbon emission reduction related measures. On the other hand, based on the 'Carbon Emissions Online' result of the detailed management and control of ecological environment zoning as the basic map, the carbon emission accounting and evaluation results of construction projects, pollution reduction and carbon reduction measures, and measure compliance analysis are summarized to create a region. A new model for reducing carbon." Zhao Ji said.
"So far, three construction projects have been evaluated based on carbon emission control goals." Cao Jingang said,"In this process, we have initially achieved the effectiveness of source control in carbon emission evaluation, deepened the synergy of pollution reduction and carbon reduction in the Beijing-Tianjin-Hebei region, and organically integrated the ecological environment zoning management and control in Tongzhou District. Under the conditions of refinement results, it is clearly stated that project access should meet the control requirements of 'carbon emissions online'."
Strengthen experience summary and condensation and expand demonstration results
"By conducting carbon accounting and evaluation on three construction projects, analyzing environmental protection measures for pollution reduction and carbon reduction, and proposing carbon emission reduction measures and suggestions, it provides a powerful starting point for the green and high-quality development of the sub-center." Cao Jingang said,"In the next step, we will further improve the technical evaluation system, promote innovation in collaborative management and control of carbon pollution, and continuously expand application scenarios."
According to reports, in the carbon accounting and evaluation work of the three construction projects, not only will the pollution reduction and carbon reduction control requirements in terms of total carbon emission control targets, carbon emission intensity, etc. be used as support and refinement for promoting the construction of environmental impact reports, it also gives full play to the guiding and service role of carbon emission evaluation, providing an important reference basis for early demonstration and decision-making of the project; It not only organically integrates the detailed results of ecological environment zoning management and control in Tongzhou District as a supporting document for project ecological environment access, but also conducts timely regional consultations on development and construction projects involving cross-regional and river basin ecological and environmental impacts, and continuously deepens joint prevention and control among the three places.
"At present, we are constantly optimizing and improving carbon emission accounting and evaluation work, initially forming technical guidance, making technical reserves that can be promoted, applied, and demonstrated, and striving to control energy consumption, process processes, energy-saving technologies, and reduction of emission sources of construction projects. Achieve all-round and full-process control in terms of carbon measures and other aspects. At the same time, we will strengthen the summary and refinement of experience, continuously expand the implementation and application fields of carbon accounting and evaluation, strengthen the application in the field of environmental assessment, and expand to support comprehensive utilization of water resources, groundwater development and utilization, and respond to climate change, so as to evaluate the effectiveness of cities 'response to climate change. Provide solid data support and contribute application scenarios to the construction of the sub-center carbon assessment system." Zhao Ji said.
"This carbon accounting and evaluation work on the Comprehensive Management and Ecological Restoration Project (Tongzhou Section) of the Chaobai River greatly inspires us to further deepen the joint construction, joint prevention and control of the regional ecological environment." Zhao Ji said that in the next step, we will also try to explore a series of working models in identifying carbon emission sources, assessing emission reduction potential, and monitoring and tracking carbon emission data. Through business collaboration and joint decision-making, we will strengthen regional green financial services, deepen the construction of the carbon emissions trading market, and strive to build a green and low-carbon pattern for coordinated industrial development in Beijing, Tianjin and Hebei.
