Recently, the Ministry of Industry and Information Technology, the National Development and Reform Commission, the Ministry of Ecology and Environment, the Ministry of Housing and Urban-Rural Development and other four departments jointly issued the "Building Materials Industry Carbon Peak Implementation Plan" (hereinafter referred to as the "Implementation Plan"), in order to better understand and implement the "Implementation Plan", the content of the "Implementation Plan" is interpreted as follows
.

I.
What is the background to the issuance of the Implementation Plan?

A few days ago, the CPC Central Committee and the State Council issued the "Opinions on Complete, Accurate and Comprehensive Implementation of the New Development Concept to Do a Good Job in Carbon Peaking and Carbon Neutrality", and the State Council issued the "Action Plan for Peaking Carbon Emissions before 2030" to make overall arrangements
for carbon peaking and carbon neutrality.

The building materials industry is an important basic industry of the national economy and an important support
for improving living conditions, managing the ecological environment and developing circular economy.
China is the world's largest producer and consumer of building materials, and the output of cement, flat glass and other major building materials products ranks first
in the world.
Due to the large scale of the industry and the characteristics of the kiln process, the building materials industry is also a key area of industrial energy consumption and carbon emissions, and is one of
the industries with the heaviest carbon emission reduction tasks in China.
Achieving carbon peak in the building materials industry is crucial
for industry and even the whole society to achieve the carbon peak goal on schedule.

In order to thoroughly implement the decision-making and deployment of the Party Central Committee and the State Council on carbon peaking and carbon neutrality, as well as the work requirements of the Implementation Plan for Carbon Peaking in the Industrial Sector, the Ministry of Industry and Information Technology and relevant departments have studied and formulated the Implementation Plan, as an important component of the national "1+N" policy system for carbon peaking, to guide the industry to carry out carbon peaking in a scientific and orderly manner
.

II.
What are the main contents of the Implementation Plan?

The "Implementation Plan" includes "3 parts, 5 tasks and 4 measures"
.

The three parts refer to the "Implementation Plan", which consists of
three parts: "overall requirements, key tasks and safeguard measures".

The five tasks refer to the five key tasks
proposed in the Implementation Plan: "strengthening total volume control, promoting raw material substitution, converting energy-using structure, accelerating technological innovation, and promoting green manufacturing".

The four measures refer to the four safeguard measures
proposed in the Implementation Plan: "strengthening overall coordination, increasing policy support, improving the standard measurement system, and creating a good environment".

Third, what is the current level of green development of China's building materials industry?

Since the 18th National Congress, the transformation and upgrading of China's building materials industry has achieved remarkable results, its comprehensive strength and competitiveness have been steadily improved, new progress has been made in green development, and the energy consumption and pollutant emission intensity of key industries and backbone enterprises have reached the world's advanced level
.
The main results are as follows: First, the optimization and upgrading
of the industrial structure.
The new production capacity of cement and flat glass has been effectively controlled, multiple measures have been taken to guide the orderly withdrawal of backward production capacity, and the scale of new building materials such as inorganic non-metals and composite materials has been expanding
.
The second is to improve
the level of energy conservation and carbon reduction.
Support the technological transformation of enterprises, promote new technologies, new processes and new equipment, accelerate the implementation of cleaner production transformation in key industries, and greatly improve
the level of energy conservation and emission reduction in the industry.
According to China's energy consumption limit standard, the comprehensive energy consumption of cement clinker products ≤ 117 kg of standard coal / ton, and the comprehensive energy consumption of flat glass products is divided into ≤ 12 kg standard coal/weight box and ≤ 13.
5 kg standard coal/weight box according to production capacity, which is generally at the world's advanced level
.
Third, the circular economy is accelerating
.
The building materials industry gives full play to the advantages of collaborative disposal, continuously improves the comprehensive utilization level of resources, and promotes the development of
resource recycling.
Taking the cement industry as an example, at present, there are nearly 300 cement clinker production lines for coordinated disposal of domestic waste, urban sludge and industrial waste relying on the new dry cement kiln technology in the country, which effectively promotes the green transformation of the industry and makes positive contributions
to the construction of China's ecological civilization.
Fourth, the development of
green building materials has accelerated.
A number of green building materials products have emerged in the fields of building doors and windows, sanitary ware, waterproof materials and other fields to improve the high-quality supply capacity
of green building materials.
Certified 58 categories of green building materials products, formed a relatively complete product system, cultivated 8 national new industrialization industry demonstration bases of green building materials, green building materials has a good development foundation
.

In general, China's building materials industry has a complete range of products, a perfect industrial chain, mature production technologies such as kiln calcination, energy consumption and pollutant emissions have reached the international advanced level, but due to the large industrial scale, high process emissions, coal energy structure, and large differences between industries, the building materials industry does have a large total amount of emissions, uneven development, etc.
, the task of carbon peaking is relatively arduous, and it is urgent to unify the thinking of the whole industry, closely focusing on the decision-making and deployment of the Party Central Committee and the State Council on carbon peaking and carbon neutrality.
Accelerate the orderly implementation of carbon peaking and carbon emission reduction in the whole industry
.

4.
How to correctly understand the relationship between the development of the building materials industry and emission reduction?

For the building materials industry, during the "14th Five-Year Plan" and even the "15th Five-Year Plan" period, the building materials industry will enter a new stage of high-quality development, and it is still in a period of important strategic opportunities.

In general, with the transformation of development mode and the upgrading of demand structure, the demand for traditional building materials products such as cement for the construction industry will enter the platform adjustment period, showing a trend of stability and decline; The demand for mineral functional materials, high-performance fibers and composite materials for emerging industries such as energy conservation and environmental protection, electronic and electrical appliances will continue to grow rapidly
.
To promote the carbon peak of the building materials industry, it is necessary to handle the relationship between different industries, seek truth from facts, classify policies, and achieve healthy development
of the industry.

The building materials industry should not only deeply understand the new opportunities and new requirements brought about by the accelerated construction of the new development pattern and the further exertion of the advantages of the domestic ultra-large-scale market, but also deeply understand the new contradictions and new challenges of the weakening of the expansion of large-scale and quantitative demand and the more urgent task of green and safe development, and make full use of the opportunities brought by the dual carbon strategy to the industrial innovation of the building materials industry, promote green transformation in development, achieve greater development in green transformation, and solidly promote the high-quality development
of the building materials industry.

5.
What is the carbon peak goal of the building materials industry?

In accordance with the overall deployment of the country and the actual situation of the building materials industry, the Implementation Plan proposes that the building materials industry achieve carbon peak before 2030, and encourages industries with conditions to peak first
.
At the same time, the main objectives
of the "14th Five-Year Plan" and "15th Five-Year Plan" phases were put forward.
During the "14th Five-Year Plan" period, the energy consumption and carbon emission intensity of key products such as cement, glass and ceramics continued to decline, and the comprehensive energy consumption of cement clinker products decreased by more than
3%.
During the "15th Five-Year Plan" period, the industrialization of green and low-carbon key technologies in the building materials industry has achieved a major breakthrough, the level of raw fuel substitution has been greatly improved, and an industrial system
for green and low-carbon circular development has been basically established.

6.
Why are the key tasks of strengthening total volume control proposed? How can this task be implemented?

Total volume control is the basis for the
carbon peak of the building materials industry.
Due to its process characteristics, the cement industry accounts for about 70% of the total emissions of the building materials industry, which is a key area
of carbon emissions in the building materials industry.

In recent years, the state has increased supply-side structural reform for key industries such as cement and flat glass, and their production capacity has been effectively controlled
.
Considering that the demand for cement, flat glass and other products has entered the platform adjustment period, with the continuous advancement of the "dual carbon" work, it is still necessary to strictly control the total
production capacity of key industries.
In the next step, in terms of strengthening total volume control, the Implementation Plan proposes to focus on promoting the following work: First, give play to the comprehensive role of policies, standards and markets, and guide the withdrawal of inefficient production capacity
.
The second is to strictly implement the capacity replacement policy of cement and flat glass industries to ensure that the total production capacity is maintained in a reasonable range
.
At the same time, strengthen the management
of lime, building sanitary ceramics, wall materials and other industries.
The third is to improve the peak-shifting production of cement and fully mobilize the enthusiasm of enterprises to implement peak-shifting production in accordance with laws and regulations
.

7.
Why is the key task of promoting raw material substitution proposed? How can this task be implemented?

Raw material substitution is the key
to carbon peaking in the building materials industry.
Major products such as cement and lime in the building materials industry require a large amount of carbonate minerals as raw materials in the production and preparation process, and carbon dioxide is formed during the carbonate decomposition process, resulting in a large amount of carbon emissions
.
According to statistics, the emissions of the production process account for more than 50% of the total carbon dioxide emissions of the building materials industry, and the carbon emission reduction work of the building materials industry urgently needs to improve the comprehensive utilization level
of resources by replacing raw materials.

In recent years, building materials has given full play to the advantages of kilns, promoted the coordinated disposal of domestic waste, phosphogypsum and other bulk solid waste resource utilization by cement kilns, consumed more than 600 million tons of industrial waste residue every year, and at the same time, disposed of more than 10 million tons
of garbage, sludge, hazardous waste, etc.
In the next step, in terms of promoting the substitution of raw materials, the "Implementation Plan" proposes to focus on promoting the following work: First, strengthen the coupling between industries, increase the proportion of limestone replaced by calcium-containing resources under the premise of ensuring the quality of cement products, and accelerate the promotion and application
of new low-carbon cement varieties.
The second is to accelerate the improvement of the utilization level of solid waste of building materials products, and support the construction of a number of cement kilns, wall materials, tunnel kilns with better energy efficiency and coordinated disposal of solid waste projects
in key towns.
The third is to promote the reduction and precise use of building materials products and accelerate the development of new low-carbon cementitious materials
.

8.
Why are the key tasks of converting the energy-using structure proposed? How can this task be implemented?

Energy optimization is the guarantee
for the carbon peak of the building materials industry.
The building materials industry mostly adopts the kiln production process, which is still dominated by fossil fuels, and the fuel combustion process inevitably produces carbon emissions, according to statistics, the fuel combustion process emissions account for more than
30% of the total carbon dioxide emissions of the entire industry.
Reducing the use of coal and fully tapping the "calcination value" of clean energy will promote the carbon emission reduction of the building materials industry
.

In recent years, the building materials industry has actively explored new energy applications such as photovoltaic power generation, and some backbone enterprises have made full use of a variety of new energy sources such as waste heat power generation, photovoltaic power generation and wind power generation, and strive to build a pilot enterprise
of "zero power purchase".
In the next step, in terms of converting the energy-using structure, the Implementation Plan proposes to focus on promoting the following work: First, increase the proportion of alternative fuel utilization and increase the replacement rate
of coal combustion in cement and other industries.
The second is to accelerate the application of clean and green energy, orderly increase the proportion of natural gas and electricity, and guide building materials enterprises to actively consume renewable energy
.
The third is to guide enterprises to strengthen the refined management of energy and improve the energy utilization efficiency level
of the building materials industry.

9.
Why are the key tasks of accelerating technological innovation proposed? How can this task be implemented?

Technological innovation is the driving force
for the carbon peak of the building materials industry.
In order to balance sustainable economic and social development and the realization of the goal of carbon peaking on schedule, it is necessary for the whole society, the whole industry and the entire industry chain to accelerate technological progress, break through key technologies, promote applicable technologies, achieve system change, and promote power change
.

In recent years, a large number of green and low-carbon technologies have emerged in the building materials industry, such as low-resistance cyclone preheaters, high-efficiency firing, high-efficiency grate coolers, high-efficiency energy-saving grinding and other energy-saving technical equipment in the cement industry, float glass kiln multi-line technologies in the glass industry, ceramic dry powder production and other technologies, which have improved the green development level of
the industry.
In the next step, in terms of accelerating technological innovation, the Implementation Plan proposes to focus on promoting the following work: First, accelerate the research and development of major key low-carbon technologies and enhance technical support
for energy conservation and consumption reduction.
The second is to accelerate the promotion of energy-saving and carbon-reduction technology and equipment, and improve the level of energy conservation and consumption reduction of
building materials enterprises.
The third is to accelerate the digital transformation of the building materials industry and use a new generation of information technology to promote energy conservation and carbon
reduction in the industry.

10.
Why are the key tasks of promoting green manufacturing proposed? How can this task be implemented?

Green manufacturing is a requirement for
the building materials industry to peak carbon.
The building materials industry should combine the characteristics of the production process such as crushing, homogenization, batching, molding, calcination, etc.
, and focus on key directions such as low-carbon process, industrial recycling, and product greening, so as to promote the green and low-carbon transformation
of the whole life cycle of the industry.

In recent years, the building materials industry has focused on "finding gaps in benchmarks and improving technological transformation", clarifying standard paths, accelerating green and low-carbon technological transformation actions in key industries, and promoting the production and application
of green building materials.
Especially since the beginning of this year, six departments, including the Ministry of Industry and Information Technology, the Ministry of Housing and Urban-Rural Development, the Ministry of Agriculture and Rural Affairs, the Ministry of Commerce, the State Administration for Market Regulation, and the National Rural Revitalization Administration, have carried out green building materials to the countryside, promoting the production and consumption
of green building materials.
In the next step, in terms of promoting green manufacturing, the Implementation Plan proposes to focus on promoting the following work: First, strengthen the green management of the whole life cycle of building materials enterprises and build an efficient and clean production system
.
The second is to build a green building materials product system, promote the construction of standard system, product certification and other related work
.
The third is to cultivate green building materials backbone enterprises and industrial clusters, carry out activities such as sending green building materials to the countryside, promote the coordinated development of green building materials and green buildings, and accelerate the production and application
of green building materials.

11.
How to ensure the effective implementation of the Implementation Plan?

The Implementation Plan focuses on promoting relevant work
from four aspects: management, policy, standards and publicity.

First, overall planning and coordination
should be strengthened.
Give full play to the coordination mechanism of departments and localities, give full play to the role of industry associations, take the lead in large building materials enterprises, and work together to promote the carbon peak
of the building materials industry.
