Reduce "carbon footprints" more "green" -Hunan implements the third report of the "double carbon" target series

Hunan Daily All -Media Reporter Liu Yinan Peng Yahui Peng Kexin

The three volts have passed, and the green is still strong. In people's unawareness, Sanxiang Greater more than 120,000 acres of forest carbon absorbing oxygen. The silent ecological process for thousands of years has now become the key to helping Hunan to achieve "carbon neutrality" and achieve "point green" through carbon transactions through carbon transactions.

The Xinhua County Affairs Affairs Center is a well -known "cut door". The "elevator below 4 floors is constantly reluctant" has been implemented in the Xinhua County Party Committee for 14 years, saving electricity and deeply rooted in the hearts of the people, and greatly reduced the "carbon footprint". Essence

In recent years, Hunan has made every effort to build a low -carbon society, develop a low -carbon economy, and cultivate a low -carbon lifestyle.

Forestry Carbon Exchange -The key to helping "carbon neutrality"

"There are many methods to absorb or remove carbon dioxide in the air, but the ability to absorb and store carbon dioxide by forests internationally, and the most efficient internationally recognized, economic feasible, and most efficient." Dai Chengdong said.

The forest growth of 1 cubic meter needs to absorb 1.83 tons of carbon dioxide and release 1.62 tons of oxygen. The dry and even tree roots of the forest can be regarded as a biomass after fixed carbon dioxide. Generally speaking, the more trees, the larger the tree, the greater the amount of carbon, and the "permanentness", the more carbon fixing.

In the next few years, my country's carbon trading market has only two trading varieties: carbon quota and forestry carbon exchange. Emiers can buy forestry carbon exchange to offset their emission reduction tasks.

Hunan is a large forestry province. As of the end of 2020, 59.97%of the land area of ​​21,800 square kilometers has been covered by forests, and the province's forest accumulation has reached 618 million cubic meters. Dai Chengdong said that for the national carbon neutralization, Hunan power, our province should realize carbon neutrality in advance, leaving room for poor forest provinces and other industrial developed areas.

In Longshan County, the Miao Autonomous Prefecture of the Xiangxi family, our province has identified more than 80,000 acres of forests as the first forestry carbon exchange project in the province. For 20 years, after being approved, this forest can reduce the amount of carbon dioxide by 1.6 million tons of carbon dioxide in the province. Based on this verification result, the transaction value can reach 56.18 million yuan.

In addition to Longshan County, our province has also planned more than ten pilot projects of forestry carbon exchange development, which is waiting for the state for approval for the country, with a total area of ​​170,000 hectares. All projects are promoted smoothly. It is estimated that the carbon reduction displacement can be reduced by 2.2 million tons/year, and the output value of carbon exchange can not be less than 88 million yuan/year.

According to Dai Chengdong's calculation, according to resource data and forestry carbon exchange pilot data, the annual carbon exchange capacity of our province can be included in the calculated amount of carbon exchange is almost doubled compared with the province's carbon emissions. In essence, the quality of forests is required to improve the quality of the forest. To this end, the province's forestry carbon exchange must be developed in an orderly manner, allowing each tree to reflect the ecological value. "

Traffic -more convenient to commute by bus

On August 25, in the charging station in the Ritto Preparation Area, the charging taxi and online taxis were endless.

At present, 93 DC fast charging piles have been built, and the intelligent flexible charging bow charging system has been built. "A DC fast charging pile can meet the charging needs of 15 new energy vehicles per day. Now there are nearly 500 new energy vehicles here to charge here every day." Zhou Wei, director of the Calling Engineering Engineering Director, said.

The construction of DC fast charging piles is just the beginning. According to Zhou Wei, the charging station will create the first large -scale optical storage charging charging station in Changsha, and will be introduced into a photovoltaic shed, which is expected to achieve a carbon reduction displacement of nearly 7,000 tons.

In recent years, Hunan has focused on creating a "green bus", and the proportion of new energy buses has continued to increase.

Last year, the Changsha Intelligent Driving Research Institute and Tencent provided technical support, creating the two smart commute bus lines of Meixi Lake -High -tech Zone. It has been operated for more than a year.

These two bus lines use intelligent connected technology to allow buses to prioritize at the traffic light intersection. Compared with ordinary buses at the same time, the average of 30.7%of the commuting time for intelligent connectivity, and about 24.7%of passengers along the line changed from private cars to bus travel.

At present, the two smart custom bus lines can turn more than 600,000 people throughout the year into bus. If each person is equivalent to reducing a car to a car, a 1085 tons of carbon emissions can be reduced throughout the year.

Zhuzhou City's intelligent rail transit system is planning to build a fast bus corridor with a "one horizontal, two vertical and one ring", with a total length of about 58 kilometers.

The project adopts an ordinary bus and wisdom rail fusion operation solution, which preferred the vehicle's real -time positioning and signal, forming a world original and leading fast transportation system in the country. Among them, Zhuzhou Zhi Rail Hunan University of Technology to Zhuzhou Railway Station West Square section has officially put into trial operation on March 30.

Based on the existing urban road transformation, the wisdom rail effectively reduced carbon emissions and air pollution in the construction process. The vehicle is driven by the vehicle, and the energy consumption is extremely low. It is expected to reduce 72,000 tons of carbon dioxide emissions during the operation of the entire life cycle.

Garbage disposal -resource utilization into scale

"Xiaole Xiaole, glass bottle." Recently, the reporter came to the E4 District E4, Beichen Delta, Beichen Delta. The resident Mr. Li was talking to the intelligent garbage classification compartment.

"The garbage is the wrong place to let go of the place, and it is the only resource on the earth that is constantly growing and never exhausted." Based on precise classification, garbage resources are treated to the next level.

In the second phase of the clean -up incineration project in Changsha, the reporter saw that the garbage operating vehicle continued to enter and exit. The thermal energy generated in the 1,000 degrees Celsius was converted into high -temperature steam, pushing the turbine to rotate, and the generator did to power generation. "The incineration of solid waste can transport an Internet electricity volume of about 4 million degrees per day, and the number of online electricity can be used by 1.1 million urban residents throughout the year." Li Fangzhi, chief engineer of Hunan Military Credit and Environmental Protection Co., Ltd., said.

The reporter learned from the Provincial Department of Housing and Construction that as of the end of 2021, there were 26 waste incineration plants in the province, and the incineration treatment capacity accounted for 68.3%of the total processing capacity.

According to incomplete statistics, the amount of construction waste in the province in 2021 was approximately 123 million tons, and the comprehensive utilization of resourceized was about 47.7 million tons.

Construction garbage, road renovation waste, etc. are excavated, recycled, recovered, broken, and sieved, and new materials such as new materials and regenerative agents, enhancers, and moisturizers are re -mixed and mixed with a certain proportion to produce construction regeneration products. Hunan Yunzhong Regenerative Technology Co., Ltd. has disposed of about 4 million tons of construction waste and road waste to achieve an output value of over 300 million yuan with urban construction waste resource resource utilization projects.

According to the relevant person in charge of the Provincial Department of Housing and Construction, our province has incorporated construction waste regeneration products into two types of products government procurement catalogs, and actively promotes the application of construction waste regeneration products into the bidding system for the total contracting bidding system of housing construction and municipal infrastructure projects.

At present, our province has achieved the entire process of construction waste. The "Hunan Provincial Building waste Information Supervision Platform" realizes the full life cycle data of construction waste generation, clearing, disposal, and product application in various regions of the province.
