A greener city, a greener industry and a lower-carbon life —— Practice observation on promoting carbon reduction in many places

On June 5th, it was World Environment Day. The reporter visited many places in China recently and saw that a more environmentally friendly city, a greener industry and a lower-carbon lifestyle have gradually become a climate. Various fields actively promoted the practice of carbon reduction and strived to create a better life in which man and nature coexist harmoniously.
From single building to the whole area, an environmentally friendly city with lower energy consumption.
On Cuiyu Road, Liangjiang New District, Chongqing, there is a house full of flowers and plants called "Chongqing House". The bougainvillea blooming all over the wall is beautiful, and dozens of plants such as golden bamboo and ivy adorn the external wall of the building, which, together with the green plants planted on the roof, makes the building integrate with the natural landscape.
Xiao Huang, deputy chief architect of Chongqing Bojian Architectural Planning and Design Co., Ltd. said: "The dense plants can help the building to insulate heat and cool down in summer, and the plants wither in winter. The direct sunlight can meet the indoor lighting requirements, and together with the tunnel wind system, solar energy absorber and rainwater collection pond, it can save electricity by 40% to 50% per square meter."

The "Chongqing house" that can reduce consumption is not a case. According to the data released by the Ministry of Housing and Urban-Rural Development, by the first half of 2022, the proportion of new green buildings in China has exceeded 90%.
All localities are constantly promoting the promotion and coverage of green buildings from single buildings to ecological urban areas and low-carbon cities. In Shanghai Qiantan International Business District, the sustainable development concept of "energy-saving, low-carbon and environment-friendly city" was written into the design drawings from the beginning.
"More than 10 years ago, when it was still a construction site, we planned the comprehensive smart energy project of Qiantan Energy Center." Zhang Yuanyuan, general manager of Shanghai Electric Power Green Energy Co., Ltd. said that the energy center is based on natural gas, and adopts the technology of combined cooling, heating and power supply and energy storage to provide air-conditioning cold and heat sources for individual buildings in the region, "integrating the energy supply systems of independent and scattered individual buildings to realize centralized energy supply and unified coordination. At present, the comprehensive utilization efficiency of regional energy reaches 81.9%, saving energy by 35.6%. "
From the park to the production line, the escalating green industry.
The office area adopts the air conditioning mode of water storage centralized energy station to reduce the power generation cost; Public transportation, shared travel and other modes of transportation "zero distance" conversion and connection; Natural resources such as wetlands and waterfalls are reserved, and most areas are drained by natural ecological grass ditch … … Hainan Ecological Software Park, located in Chengmai County, Hainan Province, is exploring the construction of green industrial parks in all directions. Chunzhi Yang, the person in charge of the park, said that according to the conversion, the carbon emission per 10,000 yuan of output value is only two kilograms, "this is a very low value".

From keeping a close eye on the "GDP per mu" of industrial land to calculating the carbon emissions per unit output value, the changes in the focus of industrial parks reflect that the concept of green development is constantly deepening. The peak carbon dioxide emissions Action Plan before 2030 issued by the State Council proposes to build a number of energy-saving and low-carbon parks that reach the international advanced level, and promote energy-saving and carbon-reducing transformation in power, steel, petrochemical and other industries.
Recently, the hydrogen supply project of hydrogen fuel cell in Chongqing Chuanwei Chemical Co., Ltd. of China Petrochemical Group has been completed, and it can supply more than 6,000 kilograms of high-purity hydrogen every day after it is put into use, meeting the hydrogenation demand of more than 300 hydrogen fuel vehicles.
"A large amount of by-product hydrogen is produced in the production process of the enterprise, and we passed ‘ Complete hydrogen purification technology for fuel cell vehicles ’ Purification costs more than 30% less than conventional hydrogen production. " Hu Ze, deputy chief engineer of Chuanwei Chemical, introduced.
Changing the "by-products" in production into "main products" with low carbon and environmental protection, the petrochemical industry is accelerating the pace of green transformation.
At the same time, China’s non-fossil energy power generation industry is developing rapidly. According to the information released by the Ministry of Ecology and Environment on May 29th, from the comprehensive EIA approval from January to April this year, 952 photovoltaic power generation projects were involved, up by 132.2% year-on-year; There were 586 projects in the wind power industry, up 36% year-on-year.
From fashion to habit, into a daily low-carbon life.
Gubei Garden Community, a gorgeous family in Changning District, Shanghai, has a bright green bill: in the past 18 years, the community has carried out energy conservation and emission reduction for public buildings, saving an average of 38,000 kWh per month; Carry out wastewater utilization, and discharge the wastewater from the water purification system into the landscape pool through the construction of pipelines, saving more than 60,000 cubic meters of water; Domestic waste classification is implemented, and the recycling rate of dry and wet waste reaches 14.33% through wet waste composting & hellip; …
Residents often sit together and talk about some green topics: what else can recycled bottles and cans do? How to build an ecological space more suitable for the survival of insects and better protect biodiversity in the community? "People often say that a green lifestyle is a fashion, and we hope that through long-term practice, fashion will become a habit, so that being close to nature, protecting the environment and advocating a green and low-carbon lifestyle will become people’s daily natural choices." Chen Lei, deputy director of Gubei Garden Community Committee of Gorgeous Family, said.

In March this year, the Measures for the Management of Carbon Pratt & Whitney in Hainan Province (Trial) was officially implemented. "This is an innovative voluntary emission reduction mechanism that rewards low-carbon behaviors and encourages the public to live a low-carbon life." Zhang Jing, director of the Finance Department of Climate Change and Science and Technology of Hainan Provincial Department of Ecology and Environment, said, "For example, if the public chooses to drive new energy vehicles or take buses and other green modes of travel, they can get carbon points in accordance with the relevant provisions of carbon Pratt & Whitney, and exchange them for coupons, small gifts and other rewards."
At present, many cities in China have carried out innovative exploration of carbon accounts, and each individual’s carbon reduction behavior will converge into an important force for the whole society to achieve the goal of "double carbon". The relevant person in charge of the Shanghai Municipal Bureau of Ecology and Environment said that we should actively practice the green production and lifestyle, promote the overall green transformation of economic and social development in high-quality development, and make every effort to build a harmonious coexistence between man and nature in beautiful homeland.
