Two years later, "low-carbon concrete" once again appeared in the heavy documents of government departments.

22 August, Ten departments, including the State Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Industry and Information Technology, the Ministry of Finance, the Ministry of Natural Resources, the Ministry of Housing, Urban and Rural Construction, the Ministry of Transport, the State-owned Assets Commission of the State Council, the State Energy Administration and the Civil Aviation Administration of China, jointly issued the Implementation Plan of the Green Low Carbon Advanced Technology Demonstration Project (hereinafter referred to as the Implementation Plan). The purpose of the implementation plan is to speed up the demonstration and application of green low-carbon advanced and applicable technologies, and forge new industrial competitive advantages in the process of implementing the target task of carbon peak and carbon neutralization. The technologies

included in this edition of the Implementation Plan are divided into three categories: source carbon reduction, process carbon reduction and end carbon sequestration. In the category of process carbon reduction: 6. Demonstration projects in the construction field. It includes advanced demonstration of ultra-low energy consumption buildings and near-zero energy consumption buildings, demonstration of energy-saving renovation of existing buildings, demonstration of near-zero carbon emission renovation of public infrastructure, demonstration of heating metering renovation, R & D, manufacturing and demonstration application of high-efficiency heat pumps, R & D, production and demonstration application of new low-carbon and zero-carbon building materials such as new cementitious materials, low-carbon concrete and advanced bio-based building materials. Following the "Action Plan for Carbon Peak by 2030" issued by the State Council on October 26, 2021, which mentioned "strengthening the R & D and application of low-carbon building materials such as new cementitious materials, low-carbon concrete, wood and bamboo building materials", two years later, "low-carbon concrete" has once again appeared conspicuously, which deserves the attention and reflection of industry enterprises! After the State Council issued the Action Plan for Carbon Peak by 2030

in 2021, the China Concrete and Cement Products Association responded quickly. On November 4, the Ready Mixed Concrete Branch of the Association and the National Construction Union Credit Certification Center jointly organized an expert symposium on "Low Carbon Concrete", focusing on "What is Low Carbon Concrete?" "How to define new cementitious materials and their application fields?" "What problems can be solved by new cementitious materials?" And so on launched a heated and extensive discussion, and condensed a lot of consensus. He also published a series of articles on "Low Carbon Concrete", which elaborated the profound insights and development suggestions of many industry experts on "Low Carbon Concrete", and attracted wide attention from readers. According to the requirements of the Implementation Plan issued on August 22 by the Expert Symposium

on "Low Carbon Concrete" held on November 4,

2021, the declaration of the first batch of demonstration projects in 2023 will be launched simultaneously, and the number of submissions from each region will not exceed 10 in accordance with the principle of selecting the best from the best and avoiding abuse. The plan further points out that through the implementation of the green low-carbon advanced technology demonstration project, a number of projects with leading technology level, outstanding emission reduction effect, coordinated pollution reduction and carbon reduction, and obvious demonstration effect will be laid out to accelerate the occupation of the global green low-carbon technology and industrial highlands, so as to provide strong support for the realization of the goal of carbon peak and carbon neutralization, and provide green kinetic energy for high-quality economic and social development.

Here, China Concrete and Cement Products Association solemnly appeals to industry enterprises to carefully study the Implementation Plan, think deeply and firmly anchor the development direction of "low-carbon concrete". Projects that meet the requirements for declaration are actively preparing for declaration.
