With the intensification of the competitiveness of the hotel industry, the hotel catering industry has also encountered unprecedented challenges, the hotel catering in order to get sustainable development, it is necessary to have the core competitiveness of the catering. The rush to make quick profits at the expense of long-term interests is currently a great malaise throughout society, and China's hotel industry is no exception. Therefore, insightful people are calling for the earth to be left without a future if the alarm bells are not rung. The Chinese government advocates the scientific concept of development, sustainable development is its main theme, the green economy has been recognized by more and more citizens, a harmonious society is not a single branch, but a hundred flowers bloom. Only a great emancipation of the mind can feel the distant past and lasting future. It is said that those who have constant production have constant mind, while we have to say that those who have constant mind naturally have constant production, and the green economy is to put the concept of everlasting life into the economic activities. Green hotel is the practitioner of environmental protection economy, green hotel in the international known as green hotel, but generally in the official occasions and formal meetings, documents and also known as eco-efficient hotel, meaning "eco-efficient hotel". With the aggravation of the earth's environmental problems, environmental protection, as a concept of human development, will affect people's daily life, and everyone will participate in environmental protection. As for enterprises, it is more important to reflect their sense of social responsibility in the process of management to ensure that their production and operation minimize the impact on the environment. In addition to manufacturers of environmentally friendly products and technologies, we do not favor the use of the name of environmental protection by enterprises to make their own profits, so the concept of the so-called "green economy" and whether it will become the mainstream of China's economic development, which is yet to be explored. It may be more accurate to use the concept of "circular economy", which is the trend of international economic development, and China's economic development is certainly no exception. Green hotel was adopted in English just for the sake of easy understanding at that time. "Green" (green) is a metaphor for environmental protection, which has been widely recognized and accepted by the public. For example, Greenpeace Organization is a famous international environmental protection organization. The English language is very inclusive and innovative, and Green hotel will also become an accepted term. In English, there is not only Eco-efficient hotel, but also Environmental friendship hotel, which means more or less the same. An article once wrote that Eco-hotel can be considered to indicate green hotel, which is more concise. The definition of green hotel is more accurate in the Green Tourism Hotel issued by the National Tourism Administration. "A hotel that takes sustainable development as its concept, adheres to clean production, advocates green consumption and protects the ecological environment. (LB/T007-2006) "In the process of operation and management, the hotel mobilizes the hotel staff and guests to join in the environmental protection, and endeavors to conserve energy and resources and reduce pollutant emissions as a way of reflecting the social responsibility of the hotel enterprise. "Let the hotel become a green hotel, let the hotel guests become green consumers", this is a modern hotel should pursue a goal. A green hotel is a hotel that takes sustainable development as its concept, integrates environmental management into hotel operation and management, applies the concepts of environmental protection, health and safety, adheres to green management and hotel operation, advocates green consumption, protects the ecological environment and rationally uses resources.　　The most basic meaning of green hotel is to save energy and reduce consumption, take all possible measures to save electricity, water, natural gas and other energy consumption, to maximize the use of resources, so that the hotel to achieve high performance operation. At present, there are many hotels that have integrated the concept of environmental protection into their design from the beginning of the building construction, such as: using special energy-saving materials to maximize the effect of heat insulation and moisture insulation to reduce the energy consumption of the hotel operation. Secondly, another concept of green hotel is to minimize pollution, minimize the emission of waste gas and other polluting behaviors to the surrounding environment. At present, the hotel industry generally adopts measures such as: soliciting guests' opinions to reduce the frequency of replacing fabric supplies; adopting clean fuels and not burning raw coal, and so on.　　In fact, the creation, implementation and maintenance of green hotels is a continuous development process, can not say which hotel from the beginning of the completion of the green hotel will always be a green hotel, there are more efforts from the management and service process of environmental protection in the consistent adherence. In fact, from the customer's point of view, sometimes the promotion of green environmental protection also bring some inconvenience to customers, such as the promotion of water use of small emissions and other measures. Therefore, the construction of green hotels is synchronized with the improvement of environmental protection awareness of the whole population, and very often it also needs the cooperation of customers. Green hotel is an environmentally friendly, ecologically efficient hotel. Green hotel has three concepts of "green, health, environmental protection" and six standards: minimum emissions, recycling and reuse of related items; effective use of energy, storage and management; management of fresh water resources; wastewater management; environmental protection procurement policy; social and cultural development.　　A green hotel is a hotel that applies the concepts of safety, health and environmental protection, adheres to green management, advocates green consumption, protects the ecology and uses resources rationally. Safety means that the hotel has appropriate public **** safety facilities and food safety assurance system. Health means that the hotel provides consumers with services and products that are beneficial to physical and mental health. Environmental protection refers to the hotel operation to reduce pollution to the environment, energy saving and consumption. Green hotels are categorized into five grades from Grade A to Grade AAAAA, using the ginkgo biloba, which has Chinese characteristics, as a logo, and are awarded to hotels assessed according to the standards. The evaluation of green hotels will be carried out by an expert committee organized by the China Hotel Association.　　In the current standard, hotels are categorized as "green" in two grades: gold leaf and silver leaf. Green Hotel is a hotel that adheres to the concept of sustainable development, adheres to clean production, advocates green consumption, protects the ecological environment and reasonably uses resources. Its basic principles are reduction, reuse, recycling and substitution. The eligibility to participate in the assessment is for tourism hotels that have been officially opened for more than one year. The assessed green tourism hotels are reviewed by provincial tourism star hotel assessment organizations once every three years. The review results are reported to the China Tourism Star Hotel Rating Organization for the record. The logo is valid for five years (calculated from the date of issuance of the certificate). The expiration date must be reapplied for and rated. The hotel industry to sustainable development, must support the upper stream industry chain, which is also an important concept of green hotel - comprehensive and harmonious development as well as sustainable development. During the implementation of green hotels, it is important to keep an eye on the suppliers of hotel products. The hotel should reach a kind of communication and cooperation with suppliers, *** with to promote the hotel's green work. Many hotels already have some effective measures, such as purchasing simple packaging consumables, purchasing durable furniture items, purchasing pollution-free vegetables and green food. We hope that suppliers of hotel equipment, products and technology will pay more attention to the needs of hotels in this regard and produce more and better "environmentally friendly" products. Green environmental protection mainly refers to the hotel in the operation process to reduce pollution to the environment, energy saving and minimize consumption, to achieve the maximization of resource utilization. At present, the concept of green environmental protection is more and more applied to the operation of urban inns, mainly from two aspects of implementation. First, it is energy saving and consumption reduction. Including: saving water, electricity, coal, natural gas and other aspects. For example: the hotel to establish a water metering system, and water consumption records, analysis; central air conditioning machine equipment to add automatic frequency converter, regulating low power under the amount of water and electricity; guest rooms using small-displacement flush toilet; energy-saving lamps are more commonly used in the hotel industry, and we will further consider the use of solar energy technology products.　　Secondly, we strive to minimize the pollution to the surrounding environment and reduce the emission of waste and exhaust as much as possible. For example, all City Inn chain hotels use heat pumps instead of boilers to burn hot water, thus avoiding the pollution of the surrounding environment caused by the waste gas from boilers; the central air conditioning uses heat recovery devices to use the heat generated by the air conditioning operation to burn water for domestic use, making use of renewable resources as much as possible. Coffee never uses disposable tableware such as disposable dishes and foaming lunch boxes, and the tableware has complete sterilization measures.　　All of the above measures are the improvement of the hotel from the hardware, but in the implementation of the staff and guests need to actively cooperate. For example: at present, many hotels will be placed on the tip card to remind guests to save water and electricity and do not change the cloth too often, but the real can be done may be a small part of the guests. This requires the hotel in the operation process of the continuity of the concept of environmental protection continue to penetrate.
