Climate change already threatens the future of humanity. At present, many countries have formulated carbon emission and carbon tax policies, escalating the issue of carbon emission reduction from the previous ethical issue to the current economic issue, which directly affects the operation of enterprises, and carbon neutrality has become one of these hot words. So, what do we often mean by carbon neutrality?
Originally, carbon neutrality was defined as a balance between carbon emissions and carbon sinks (systems that absorb more carbon dioxide than carbon emissions, such as forests, soils, and oceans) over a specific period of time, thereby eliminating additional carbon dioxide emissions produced by humans.
On a smaller scale, when carbon neutrality is set as a national and corporate goal, it is mainly achieved through carbon emission reduction at source and end-of-line offsetting. That is, carbon emissions are minimized first, and then carbon offsets are carried out through afforestation, soil carbonization, peatland restoration, direct air carbon capture and storage (DACCS), etc., to artificially create carbon sinks and achieve carbon neutrality.
Taking the construction industry as an example, in 2020 alone, the total carbon emissions of the whole process of construction in the country will be 50800 million tco, accounting for 50 percent of the country's carbon emissions9%。Among them: carbon emissions in the production stage of building materials 282TCO, accounting for 28 percent of the country's total carbon emissions2%；Carbon emissions during the operation phase of the building 21600 million TCE, accounting for 21 percent of the country's total carbon emissions7%。It can be seen that the production stage of building materials and the operation stage of buildings are the main carbon emissions. If we want to achieve carbon neutrality as soon as possible, reducing the carbon emissions from the production of building materials and the carbon emissions from the later operation of buildings is the key.
Therefore, in order to effectively reduce the carbon emissions of the construction industry and achieve carbon neutrality as soon as possible, the country has begun to vigorously promote the integration technology of building insulation and structure.
The integrated technology integrates the functions of thermal insulation and wall enclosure, and the wall does not need to take additional insulation measures to meet the requirements of the current standards, and realizes the new technology of thermal insulation and building life and convenient construction, which is an important measure to effectively solve the common quality problems of energy-saving and thermal insulation projects and fire safety, in line with the national energy conservation and emission reduction development direction and industrial policy, and is of great significance to China's early realization of carbon neutrality.
At present, there are more and more integrated thermal insulation materials in the market, this kind of thermal insulation materials have passed the national green product certification, have ultra-low thermal conductivity, and the fire rating is at grade A and above, in addition, they generally have the characteristics of frost resistance, waterproofness, bending resistance, strong dimensional stability, long service life, etc., and facilitate construction, which can effectively save the construction period. WJ reinforced connection composite insulation board is one of the representatives of this type of product.
China has set the goal of carbon neutrality by 2060, and there is a long way to go. However, carbon neutrality has become a trend of the future, and many countries have set relevant targets for this important initiative. It is believed that with the joint efforts of all industries, China can effectively reduce carbon emissions, create carbon sinks through various green activities, and finally effectively complete the goal of carbon neutrality.
