    More environmentally friendly and greener -- look

     Transportation industry is a key field to promote green development and achieve carbon peak and carbon neutralization. In recent years, China's transportation industry has actively promoted the green and low-carbon transformation, vigorously adjusted the transportation structure, promoted the use of new energy vehicles, and achieved positive results.

    "Where do you go?" "Heze has the final say." in Shandong, custom buses are welcomed by more and more people. In recent years, in order to meet the diversified travel needs of citizens, Heze public transport group has set up customized bus lines. At present, there are campus lines, commuter lines and other types.
    "Public transport priority" is undoubtedly an important way to practice green travel. Last year, the Ministry of transport and the national development and Reform Commission jointly issued the green travel creation action plan, which clearly advocated a simple, moderate, green and low-carbon lifestyle by carrying out the green travel creation action, guided the public to give priority to green travel modes such as public transport, walking and cycling, reduced the traffic volume of cars and improved the overall level of green travel in China.
    Launch customized bus lines, build special bicycle roads, and accelerate the promotion of new energy and clean energy... All departments across the country responded positively and came up with new and wonderful ideas one after another. Nowadays, the green travel atmosphere is becoming stronger and stronger, and green travel is becoming the habit of people. According to statistics, by the end of last year, the number of new energy vehicles in urban public transport, cruise taxis and urban logistics distribution vehicles had reached 466000, 132000 and 430000 respectively.
    At the end of May this year, the Hebei section of Beijing Xiong Expressway in xiong'an new area was opened to traffic. According to the project leader of CCCC first public works bureau group, the project has high safety and environmental protection requirements, high standardization requirements and high quality requirements. In terms of smart high-speed construction, Jingxiong high-speed comprehensively uses the new generation of information technologies such as Beidou high-precision positioning, big data and artificial intelligence, and has also set up more than 3700 smart light poles across the line, which have the functions of intelligent perception, smart lighting, energy conservation and consumption reduction.
    High speed railway is also an important symbol of modern "green transportation". Since the completion and operation of China's first Beijing Tianjin Intercity Railway with a design speed of 350 kilometers per hour in 2008, a large number of high-speed railways have been completed and put into operation. Especially since the 18th National Congress of the Communist Party of China, China's high-speed railway development has entered the fast lane, with an average annual operation of 3500 kilometers, and has successfully built the world's largest and most modern high-speed railway network.
    According to the data from China National Railway Group Co., Ltd., in terms of energy conservation, the energy consumption per 100 km of high-speed rail is only 18% of that of aircraft and about 50% of that of buses. In terms of land saving, compared with 4-lane expressway, the land occupied by high-speed railway is only 50%, and the land occupied by completed unit transportation volume is only 10%. In terms of environmental protection, the carbon dioxide emission of high-speed rail is only 6% of that of aircraft and 11% of that of cars. From 2012 to 2019, the increased passenger turnover of high-speed rail will reduce carbon dioxide emissions by 23.2 million tons compared with the same passenger turnover completed by highway.
    In addition, the freight capacity of existing lines released by high-speed rail operation has created favorable conditions for increasing railway traffic volume and optimizing transportation structure, and promoted the green transformation and development of transportation.
    At the same time, high-speed railway adopts electrification technology, and its construction and development has significantly improved the railway electrification rate. At present, the national railway electrification rate has reached 74.9%; The annual fuel consumption of National Railways has decreased from the peak of 5.83 million tons in 1985 to 2.31 million tons at present, which is equivalent to reducing carbon dioxide emissions by 12.56 million tons per year.
    In terms of civil aviation, reducing aircraft fuel consumption and carbon emission is the core task of green development of civil aviation industry. Ma Xulun, chairman of China Southern Airlines Group Co., Ltd., introduced that in recent years, China Southern Airlines has started from one lever and one rudder to create a whole process flight energy-saving mode.
    When the plane lands, the university asks when to release the landing gear. The landing gear is put too early, resulting in high resistance and fuel consumption; Put it too late and affect safety. China Southern Airlines obtained the best altitude through big data calculation. At present, China Southern Airlines has calculated 19 similar fuel saving points, covering various stages such as takeoff, cruise and descent, so as to realize the fine management of the whole flight process.
    It is reported that from 2018 to 2020, China Southern Airlines saved 127000 tons of fuel, reduced 401000 tons of carbon emissions, and reduced fuel consumption per ton kilometer from 0.2018 kg to 0.1824 kg.
    In addition to airlines, airports are also quietly carrying out a "green revolution". Entering the airport, a mobile phone can pass all the way, "paperless" travel has become a scene that many passengers are used to.
    According to the data of Civil Aviation Administration, from 2019 to 2020, "paperless" will save 430 million yuan in paper and investment costs for airlines and airports, effectively reduce 8622 tons of carbon emissions in the whole industry, and achieve remarkable social and economic benefits.
    It is predicted that during the "14th five year plan" period, more than 2 billion people in China will enjoy the "paperless" convenient travel service, and the "paperless" convenient travel will reduce the check-in time for passengers by more than 2 billion hours.
    The use of new energy vehicles also makes an important contribution to green development. By the end of last year, the use of new energy vehicles in airports in China accounted for nearly 1 / 5. Taking Beijing Daxing International Airport as an example, the use of new energy vehicles accounts for more than 4 / 5. In terms of air quality improvement, 400000 tons of aviation fuel were saved, which is equivalent to reducing about 1.3 million tons of carbon dioxide emissions and about 4800 tons of various air pollutants. The consumption intensity of gasoline and diesel at the airport decreased significantly.
