Reading prompt

Zero -carbon, as a new concept and new practice under the goal of "double carbon", is improving all aspects of people's lives. Zero carbon practice in the fields of diet, residence, travel, etc. is undergoing. Experts said that zero carbon should be used as a long -term goal, stable and promoted in an orderly manner.

A milk discharge of zero -carbon emissions during the acquisition of raw materials and production, transportation, sales and abandonment; a building is superimposed through multiple technologies such as green production capacity, efficient energy saving, to achieve zero carbon operation; a high -speed service area rely on ecological design, circulating utilization, and use, and recycling. Energy replacement, realize zero carbon operation ...

Zero -carbon's once -strange vocabulary, as a new idea and new practice under the goal of "double carbon", is positively infiltrated into all aspects of people's lives. Zero -carbon is not completely discharged by carbon dioxide at all, but instead of calculating greenhouse gas emissions, the design scheme to reduce carbon footprint and reduce carbon emissions until the relative zero emissions of carbon are reached. What is the progress of zero carbon practice in the industry? What are the difficulties in the process of achieving zero carbon? How will zero carbon affect people's lives? In this regard, the reporter of "Workers' Daily" conducted a visit.

Food companies have exerted their efforts

Recently, in a Huaian Life Supermarket in Xicheng District, Beijing, the reporter saw that two milk is being sold on the shelves. In addition to the brand logo and milk category, the prominent position also indicates the word "carbon neutrality".

In 2022, it was called the first year of zero -carbon food, and many food companies exerted their efforts to zero carbon. "Zero -carbon food is a new concept." Luo Yunbo, a professor at the School of Food Science and Nutrition Engineering, China Agricultural University, said that in fact, carbon emissions can be generated in various aspects such as breeding, processing, transportation, and storage. At present, enterprises mainly adopt energy -saving emission reduction and carbon emissions transactions to achieve carbon neutrality, reaching the relative zero emissions of carbon.

It is understood that zero -carbon food manufacturers can reduce carbon emissions through as little use of fertilizer pesticides, use clean energy processing, and improve packaging recycling and reuse, and achieve carbon neutrality through planting sand and agricultural carbon. The birth of zero carbon food requires carbon inspection and carbon neutralization. For enterprises, carbon reduction input and certification expenditure are all costs that need to be paid for zero carbon.

Under technical challenges and cost pressure, where is the motivation for companies to pursue zero carbon? Luo Yunbo said that on the one hand, under the "double carbon" goal, energy conservation and emission reduction are the general trend, and the first realization of zero carbon is conducive to the test of survival of the fittest in the future; on the other hand, zero carbon contains profound social value, It is also very helpful for enterprises to establish a good brand image; in addition, consumers' willingness to buy environmental products is continuously enhanced, and enterprises can attract more consumers.

However, Luo Yunbo also reminded that there is currently no clear concept about zero -carbon food, and most of the publicity concepts of enterprises themselves.

Zero -carbon building promotes green development of urban and rural construction

A building with an area of ​​3467 square meters can reach 112%of the energy -consuming rate. Through renewable energy, green building materials, ventilation and emission reduction technologies, zero energy consumption and zero emissions ... Previously, China Sino -Singapore Tianjin Ecological City Real Estate The registration center was evaluated in Tianjin's first zero -carbon building demonstration project. According to reports, the building can reduce carbon dioxide emissions by 329 tons each year, equivalent to 3,000 trees.

The "Research Report on China Construction Energy Consumption and Carbon Emissions (2021)" released by the China Architectural Energy Conservation Association shows that the entire process of carbon emissions in my country accounts for about 50%of the country's total carbon emissions.

"Zero -carbon building refers to the full use of the energy -saving measures and renewable energy resources of the building's body, so that the annual carbon reduction volume of renewable energy carbon dioxide is greater than equal to all the construction of all carbon dioxide emissions throughout the year." "Carbon Building Confirmation and Evaluation Guide" pointed out that it is necessary to identify zero -carbon buildings through evaluation of the building's control indicators and carbon emissions.

The reporter learned from the Ministry of Housing and Urban -Rural Development that in many places, it continued to explore technical measures for renewable energy construction application and develop zero -carbon building. For example, Fujian Province vigorously promotes the integrated application of renewable energy buildings such as solar photovoltaic photovoltaic light, and encourages the integration and development of intelligent photovoltaic and green buildings.

In addition, prefabricated buildings that fit low -carbon construction and circular economy have also been highly respected in recent years. Data show that in 2021, the new construction area of ​​the country reached 740 million square meters, an increase of 18%year -on -year, accounting for 24.5%of the new construction area.

Energy transformation boosted zero carbon transportation

A few days ago, the country's first "zero -carbon service area" was officially put into use in Jinan East. Data from the Shandong Expressway Group show that the average annual carbon reduction of the annual carbon reduction after the project is far exceeding the average carbon dioxide emissions of more than 2,300 tons in the previous year, achieving zero carbon operation.

Transportation is one of the important areas of carbon emissions, accounting for about 10%of my country's total carbon emissions. Low -carbonization of transportation system is one of the key starting points for achieving "double carbon" goals in the transportation field.

"Vigorously promote new energy vehicles and energy -saving vehicles, and use alternative fuel vehicles to reduce carbon emissions is an important way to achieve zero carbon transportation." Zhang Xiang, director of the New Energy Automobile Technology Research Institute of Jiangxi New Energy Technology Vocational College Zero carbon transportation means that the penetration rate of new energy vehicles and alternative fuel vehicles in the field of transportation will grow rapidly. Zhang Xiang believes that the cost is one of the difficulties to promote new energy vehicles and fuel substitution. "Taking hydrogen fuel cell vehicles as an example, the green hydrogen produced by clean energy can really achieve environmental protection, but it must face high preparation costs." Zhang Xiang also mentioned that although new energy vehicles can achieve zero carbon emissions when driving, new energy vehicles can achieve zero carbon emissions when driving. However, about 70%of our country's power generation is thermal power generation, and carbon will be released during the power generation process. In the future, it is necessary to promote the transformation of power generation to wind power and photovoltaic power generation.

In addition, exploring the application scenarios of carbon -Puhui in many places, converting walking, riding, taking bus, and taking the subway to carbon reduction displacement, and encouraging the public to guide the public with low carbon travel through reward methods such as coupons. The "oil exchange" and energy feedback devices of the bus "turning waste into treasures" of rail transit energy are all ongoing energy -saving and emission reduction practices.
