What is the research status of green logistics at home and abroad??

by admin

green logistics refers to the purification of the logistics environment while restraining the harm of logistics to the environment in the logistics process, so as to make the best use of logistics resources. With the deepening of the deterioration of environmental resources, the threat to human survival and development is greater and greater. Therefore, people pay more and more attention to the utilization and protection of the environment. The development of modern logistics must give priority to environmental problems. It is necessary to improve the logistics system from the perspective of environment, that is, it is necessary to form an environmental symbiotic logistics management system. Based on the maintenance of the global environment and sustainable development, this logistics management system changes the one-way relationship between development and logistics, consumer life and logistics. While restraining the harm of logistics to the environment, it forms a logistics system that can promote the healthy development of economy and consumption, that is, it changes to green logistics. Therefore, modern green logistics management emphasizes the overall and long-term interests, emphasizes all-round attention to the environment, reflects the enterprise green image, and is a new trend of logistics management

I. Theoretical Basis of green logistics

(I) sustainable development theory

sustainable development refers to the process of meeting the needs of contemporary people without threatening the ability of future generations to meet their needs. The Research Report “our shared future” published by the International Commission on environment and development in 1987 proposed that the development and utilization of resources in the contemporary era must be conducive to the maintenance of the environment of the next generation and the sustainable utilization of resources. Therefore, in order to achieve long-term and sustainable development, we must take various measures to maintain our natural environment. This economic sustainable development policy is also applicable to logistics management activities. Due to the inevitable consumption of energy and resources and environmental pollution in the process of logistics, various measures must be taken to maintain the natural environment in order to achieve long-term and sustainable development. Based on the theory of sustainable development, modern green logistics management forms the complementary promotion and restriction relationship between logistics and environment, which promotes the development of modern logistics and achieves the symbiosis of environment and logistics

(II) ecological economics theory

ecological economics is a science that studies the law and application of material circulation, energy transformation and value-added between economic system and ecosystem in the process of reproduction. Logistics is an important link in the process of social reproduction. It includes not only material recycling and energy transformation, but also value transformation and value realization. Therefore, logistics involves two systems of economy and ecological environment, which naturally builds a bridge between economic benefits and ecological benefits. The traditional logistics management does not deal with the relationship between the two, too much emphasis on economic benefits, while ignoring environmental benefits, resulting in the decline of the overall social benefits. Economic benefits mainly involve current and local interests, while environmental benefits are related to macro and long-term interests. The emergence of modern green logistics has better solved this problem. Guided by the general principles of economics and based on ecology, green logistics studies the economic behavior, economic relations and laws of logistics and the relationship between ecosystem, so as to seek the best combination and coordinated development of ecology and environment under the conditions of ecological balance, economic rationality and advanced technology

(III) ecological ethics theory

ecological ethics forces people to deeply reflect on the environmental problems caused in the process of logistics, resulting in a strong sense of social responsibility and obligation. In order to survive and develop healthily and safely, and for the vital interests of generations to come, mankind should consciously maintain ecological balance. This is the unshirkable responsibility entrusted to us by the times, and it is also the rights and obligations of mankind to nature. It is from ecological ethics that green logistics gets moral support

Second, how to implement green logistics management

as an important part of today’s sustainable economic development, green logistics management is of great significance to the development of economy and the improvement of people’s quality of life. Both relevant government departments and enterprises should strengthen logistics management and jointly build a framework for the development of green logistics

(I) the government’s green logistics management measures

1 management of occurrence sources: it mainly manages the sources of environmental problems in the logistics process. Due to the increasing logistics activities and the development of distribution services, the number of vehicles transported in transit increases, which will inevitably lead to the aggravation of large steam pollution. The following measures can be taken to control the occurrence source: formulate corresponding environmental regulations and limit the exhaust emission and vehicle type; Take measures to promote the use of vehicles that meet the restrictions; Popularize the use of low pollution vehicles; Limit the noise generated by vehicles. Since the late 1990s, China has continuously strengthened the control of pollution sources. For example, in order to control air pollution, Beijing has issued two-stage control objectives. It has not only formulated strict emission standards for newly produced vehicles, but also carried out treatment and transformation for in-service vehicles. While encouraging the improvement and renewal of vehicles, it has taken measures such as limiting driving routes, increasing vehicle detection frequency and charging emission fees according to the amount of emission, The emission of pollutants has been greatly reduced

2 management of traffic volume: give play to the guiding role of the government and promote the transformation of enterprises from self-use vehicle transportation to business truck transportation; Promote enterprises to choose reasonable transportation mode and develop joint distribution; The government coordinates the construction of logistics center; Build a modern logistics management information network, so as to finally realize the benefits of logistics, especially to improve the logistics efficiency of small and medium-sized enterprises. Through these measures to reduce cargo flow, effectively eliminate staggered transportation, alleviate traffic congestion and improve cargo transportation efficiency

3 management of traffic flow: the government invests corresponding funds to establish circular roads in the central part of the city and formulate relevant road parking management regulations; Take measures to modernize the traffic control system; Carry out the development of grade separation between roads and railways. In order to reduce traffic congestion, improve the efficiency of distribution and achieve the purpose of environmental protection

to promote green logistics, in addition to strengthening government management, we should also pay attention to the advocacy of private green logistics, strengthen the green management awareness of enterprises, and give full play to the role of enterprises in environmental protection, so as to form a self-discipline logistics management system

(II) enterprise green logistics management measures

1 green transportation management < br>
(1) carry out joint distribution: joint distribution refers to the distribution activities jointly organized and implemented by multiple enterprises. Several small and medium-sized distribution centers unite to distribute goods to customers in a certain region. It mainly refers to the situation that the number of goods required by customers in a certain region is small, the use of vehicles is not full, and the utilization rate of distribution vehicles is not high. Joint distribution can be divided into two types: joint distribution with the owner as the main body and joint distribution with the logistics enterprise as the main body. From the perspective of cargo owners, logistics efficiency can be improved through joint distribution. For example, small and medium-sized wholesalers, if their respective distribution is difficult to meet the distribution requirements of retailers in multiple batches and small batches. By adopting joint distribution, the deliverer can realize a small amount of distribution, and the receiver can conduct unified inspection, so as to improve the logistics service level; From the perspective of logistics enterprises, especially some small and medium-sized logistics enterprises are limited in logistics rationalization and efficiency due to the constraints of capital, talents and management, less traffic volume, low efficiency, more vehicles and undertaking business alone. If we cooperate with each other and adopt joint distribution, the problems of raising funds, bulk goods and improving vehicle utilization through information network can be better solved. Therefore, joint distribution can maximize the utilization efficiency of personnel, materials, funds, time and other resources and maximize economic benefits. At the same time, redundant staggered transportation can be removed, and social benefits such as traffic mitigation and environmental protection can be achieved

(2) adopt the compound consistent transportation mode: the compound consistent transportation () refers to a way of absorbing the advantages of basic transportation modes such as railway, automobile, ship and aircraft, organically combining them, and implementing the mutual connection of multi links, multi sections and multi means of transportation for commodity transportation. This mode of transportation takes containers as the general medium to connect various tools, which plays a role in promoting composite direct transportation. Therefore, the loading tools and packaging dimensions are required to be standardized. As containers and other packaging forms are adopted in the whole process, the packaging expenditure can be reduced and the cargo damage and cargo difference during transportation can be reduced. It overcomes the inherent advantages of single transportation mode and compound transportation mode, so as to ensure the inherent efficiency of transportation mode; On the other hand, from the perspective of logistics channels, it effectively solves the separation of goods in production and marketing space and time caused by various market environment differences such as geography, climate and infrastructure construction, and promotes the close combination between production and marketing and the effective operation of enterprise production and operation

(3) vigorously develop third-party logistics: Third Party Logistics () is a business mode in which logistics enterprises other than suppliers and demanders provide logistics services. The development of third-party logistics, in which these enterprises specializing in logistics business provide logistics services for suppliers or demanders, can consider the rationalization of logistics from a higher perspective and more widely, simplify the distribution links and carry out reasonable transportation, which is conducive to the rational utilization and allocation of material resources in a wider range, and can avoid the occupation of funds, low transportation efficiency, cumbersome distribution links, increased burden of enterprises caused by their own logistics Increasing urban pollution and other problems. When the vehicle distribution in some big cities is greatly saturated, the emergence of professional logistics enterprises reduces the number of transport vehicles in big cities, thus alleviating the pressure of logistics on urban environmental pollution. In addition, enterprises should also use raw materials that save resources and reduce pollution and environment as power for various means of transport, such as liquefied gas and solar energy as the power of urban means of transport; Or respond to the call of the government to speed up the upgrading of transportation tools

2 green packaging management

green packaging refers to the packaging that saves resources and protects the environment. The main ways of green packaging are: to promote the production department to adopt the packaging made of degradable materials as simple as possible; In the process of circulation, measures should be taken to realize the rationalization and modernization of packaging:

(1) packaging Modularization: the standard for determining the basic size of packaging, that is, packaging modularization. After the packaging module standard is determined, all kinds of products entering the circulation field need to be packaged according to the size specified by the module. Modular packaging is conducive to the collection of small packages, and containers and pallets are used for packing and loading. If the packaging module can be unified with the size module of warehouse facilities and transportation facilities, it is also conducive to transportation and storage, so as to realize the rationalization of logistics system

(2) large scale and containerization of packaging: it is conducive to the mechanization of the logistics system in the process of loading and unloading, relocation, storage and transportation, accelerate the operation speed of these links, reduce unit packaging, save packaging materials and packaging costs, and protect the goods. Such as container, container bag, pallet and other container loading methods

(3) treatment of multiple, repeated use and waste packaging: general packaging is adopted without special arrangement for return; Turnover packaging is adopted, which can be used repeatedly, such as beverage, beer bottle, etc; Cascade utilization: the packaging materials after one-time use can be transformed into other uses after use or simply treated for other uses; The waste packaging materials are recycled and transformed into other uses or new materials

(4) development of new packaging materials and packaging appliances
