With the arrival of the strongest cold wave since this winter, North China, Huanghuai and other places ushered in a wide range of rain and snow weather, and the local minimum temperature reached the extreme value of the same period in history, but Tunhetou Village, Zhangxiutun Town, Zaoqiang County, Hengshui City, Hebei Province was a warm and harmonious place. Referring to this year's winter heating, villager Lu Guitai particularly praised: "I don't worry about the cold weather this year, natural gas is safe and convenient, there is no peculiar smell, and the house can reach 178 degrees”
Recently, the inspection personnel of China Gas in Tang County, Baoding City, braved the wind and snow to inspect the gas pipeline network facilities.
In order to fulfill social responsibility and help the country win the battle to defend the blue sky, as a large-scale cross-regional comprehensive energy and service enterprise in China, China Gas Holdings Co., Ltd. (hereinafter referred to as "China Gas") has actively responded to the call of the country and has fully entered Hebei, Henan, Shaanxi, Shandong, Shanxi, Inner Mongolia, Ningxia and other places since 2017. In the past six years, the company has implemented 237 coal-to-gas projects in the above-mentioned areas, connected 7.58 million users, and put into operation more than 180,000 kilometers of gas pipelines, allowing more than 40 million rural residents in the northern region to use piped natural gas 5-10 years ahead of schedule, contributing to the "responsibility of China Gas" in the process of air pollution prevention and rural revitalization in China.
Help the country reduce carbon emissions by more than 2800 million tons
Ordinary people are no longer "smoky" in winter heating
As we all know, for a long time, the air pollution in Beijing-Tianjin-Hebei and the surrounding areas has been a "painful pain" for the people in various places. In January 2013, Beijing experienced a persistent, widespread, and high concentration of severe air pollution, PM2The concentration of 5 was once close to 160 micrograms, which attracted great attention at home and abroad. However, as of last year, Beijing's PM25 The concentration has dropped to 30 micrograms, and the number of heavily polluted days has dropped from the original 58 days to the current 2 to 3 days, and "Beijing Blue" has become the norm, and it has been recommended by the United Nations Environment Programme as the "Beijing Miracle" to countries around the world.
Winning the battle to defend the blue sky is a solemn commitment to the broad masses of the people. On December 11, the ** Information Office held a regular policy briefing, at which Liu Bingjiang, Chief Engineer of the Ministry of Ecology and Environment and Director of the Department of Atmospheric Environment, introduced the "Action Plan for Continuous Improvement of Air Quality" (hereinafter referred to as the "Action Plan") issued a few days ago, and summarized China's experience and achievements in air pollution prevention and control in the past ten years.
In an interview with reporters, Liu Bingjiang pointed out that China's natural gas consumption has doubled from nearly 170 billion meters in 2013 to 2020. "The new natural gas is mainly used for urban consumption and coal-to-gas conversion, which is a very critical measure. Over the past eight years, we have concentrated resources and concentrated forces to mainly control scattered coal and relatively inefficient coal, such as boilers and industrial kilns, etc., the country's coal-fired boilers and kilns have been reduced by more than 400,000 units, the energy consumption structure of 25 million rural residents has been changed, and the people have also bid farewell to the smoky and fire-burning energy consumption mode, which has reduced coal consumption by about 500 million tons and carbon dioxide by 1 billion tons in the past eight years. ”

Behind the above outstanding emission reduction report card, China Gas has made outstanding contributions. The "2+26" cities in Beijing-Tianjin-Hebei and surrounding areas are the "main battlefields" for China Gas to deploy coal-to-gas projects in the past six years. According to Xiong Wei, president of the China Gas Future Research Institute, up to now, the company has provided more than 88500 million m of natural gas is used for winter heating. At the same time, from 2018 to March 2023, the company has helped the country achieve a CO2 reduction of more than 2800 million tons, sulfur dioxide emission reduction of about 1.93 million tons, nitrogen oxide emission reduction of about 1.02 million tons, carbon monoxide emission reduction of about 2.09 million tons, solid particulate matter emission reduction of about 33.62 million tons. Among them, the reduction of carbon dioxide emissions is equivalent to planting 15.3 billion trees. It can be seen that speeding up the treatment of scattered coal and promoting the transformation of coal-to-gas clean heating can effectively solve the problem of air pollution in the northern region and achieve a significant improvement in ambient air quality.
Reduce the incidence of respiratory diseases in the north
The rural coal-to-gas switch not only warms the house, but also warms the heart
It is necessary to be warm indoors and blue sky outside the window. "The large-scale application of natural gas, a clean energy source, in northern China has not only effectively reduced the air pollution caused by coal soot emissions, but also made a clean and tidy indoor environment and rural appearance become the norm along with warmth.
Ten years ago, each farmer in the village burned an average of about 2 tons of raw coal and a lot of firewood bales every year. Since China Gas entered the local area in 2019 to promote the conversion of coal to gas, now when you walk into Xihubao Village, you will be greeted by a picture of a harmonious and livable beautiful countryside, where the pungent smell of soot in the past, the dirty and messy coal-fired boiler room, and the scenes of villagers buying coal, transporting coal, collecting fires, and pouring ashes in winter have long been gone.
Switching from coal to gas not only warms the houses of every household, but also warms the hearts of ordinary people. The reporter walked into the home of Zhang Shasha, a villager in Xihubao Village, and found that each bedroom was equipped with radiators and other heating devices according to different needs, and the kitchen with easy-to-operate wall-hung stoves and gas cookers was also well arranged, which was completely comparable to the residences in the city. "In the past, it was the norm to burn coal for heating, smoke and fire, and it was dirty and tiring to transport coal and dust, and it was normal to use an additional 150 yuan a can of bottled liquefied gas for cooking, and it was the norm to use ten cans and eight cans a year. It's so easy now, you can heat at the touch of a button, you can have hot water 24 hours a day, and cooking is cheaper than using bottled liquefied gas," says Zhang.
China Gas goes deep into rural areas to provide users with clean energy services.
In addition, the absence of coal, firewood, grass and ash dumped everywhere has fundamentally improved the air quality in the lower floors, which in turn has greatly reduced the incidence of respiratory diseases in the northern region. The Lancet, an internationally renowned medical journal, released the Lancet Countdown to Population Health and Climate Change China Report (2023) in November this year. According to the report, due to the implementation of China's "Three-year Action Plan for Winning the Blue Sky Defense War", about 28 percent were avoided between 2015 and 2020240,000 premature deaths. Among them, due to coal substitution actions such as coal-to-gas conversion in North China, the household aspect has been avoided2890,000 premature deaths, contributing the most among all segments. It can be seen that promoting the reform of rural energy structure is not only winning clear water and blue sky, but also a win-win situation of environmental, economic and social benefits.
From "2+26" to "2+36" cities
The coal-to-gas conversion has been carried out at a non-stop pace and with undiminished intensity
It is understood that China has become the country with the fastest improvement rate of air quality in the world, and the problem of coal-source pollution has been basically solved, but Liu Bingjiang pointed out that the turning point of China's air quality from quantitative to qualitative change has not yet arrived, and the problems of heavy pollution are still frequent and frequent, the industrial structure is biased towards chemicals, and the energy structure is biased towards coal.
Now, with the issuance of the Action Plan, it marks that China's air pollution prevention and control has entered a new stage. As the third "Ten Atmospheric Measures" issued by the state after the "Action Plan for Air Pollution Prevention and Control" and the "Three-year Action Plan for Winning the Blue Sky Defense War", the "Action Plan" reflects China's continuous attention to air pollution control. For example, the urban scope of the key prevention and control areas has been adjusted compared with before. Among them, the Beijing-Tianjin-Hebei region and its surrounding areas have been adjusted from the original "2+26" cities to "2+36" citiesThe target is to achieve PM2 in cities at and above the prefecture level across the country by 20255. The concentration will be reduced by 10% compared with 2020, and the proportion of days with severe pollution and above will be controlled within 1%. Total emissions of nitrogen oxides and VOCs decreased by more than 10% respectively compared to 2020. Beijing-Tianjin-Hebei and surrounding areas, Fenwei Plain PM25. The concentration decreases by %.
In order to achieve the above goals, the Action Plan proposes 9 key tasks and 36 sub-tasks. Among them, in terms of optimizing the energy structure, it is proposed to vigorously develop new energy and clean energy, strictly and reasonably control the total coal consumption, actively carry out the shutdown and integration of coal-fired boilers, implement clean energy substitution for industrial furnaces, and continue to promote clean heating in the northern region. This means that six years later, China Gas's coal-to-gas conversion will continue.

It is not only the goal, but also the duty and mission to accelerate the promotion and application of natural gas, lay the pipeline network to thousands of households, improve the quality of life of rural residents, and help the country win the battle to defend the blue sky. "We are trying to change the traditional energy Xi of rural residents for thousands of years, which is a great undertaking that has never been done before. Focusing on the blue sky and white clouds, thinking about the happiness of the people, and sharing worries about rural revitalization, China Gas still has a long way to go, but we will unswervingly go on!Liu Minghui, chairman of the board of directors and president of China Gas, said.
