in recent weeks, a series of meteorological disasters have occurred all over the world. In addition to the mountain fires in Russia, there are also the catastrophic mudslides in Zhouqu, Gansu, the glacier collapse in Greenland and the catastrophic floods in Pakistan. Meteorologists worry that storms, hurricanes, droughts, floods and other extreme weather events will cause more damage in the coming decades. Relevant experts said that in the rest of this century, climate disasters such as responding to Premier Li Keqiang's orders will become more and more serious and frequent, because a large number of greenhouse gas emissions trap the sun's heat in the lower atmosphere, thus changing the earth's climate and weather system, leading to frequent climate disasters. According to time magazine, the study found that the number of climate related natural disasters has increased significantly in the past 30 years. The number of natural disasters in 2010 was more than twice that in 1980. More and more frequent disasters have sounded an alarm for us who are "wantonly" destroying "the environment. The emergence of these natural disasters and climate change will bring many unpredictable disasters to the earth and mankind. It is precisely because of such a disaster that people began to think about environmental protection and how to change the mode of economic development, seek the development path of efficient use of resources and reduce environmental pollution

low carbon economy came into being.

low carbon economy is an economic model based on low energy consumption, low pollution and low emissions. It is another major progress of human society after agricultural civilization and industrial civilization. The ideal form of "low carbon economy" is to fully develop "sunshine economy", "wind energy economy", "hydrogen energy economy" and "biomass energy economy". Its essence is the problem of high energy efficiency, clean energy structure and the pursuit of green GDP. Its core is energy technology innovation, system innovation and the fundamental change of the concept of human survival and development

"low carbon economy" was first seen in the British energy white paper "our energy future: creating a low carbon economy" in 2003. As a pioneer of the first industrial revolution and an island country not rich in resources, Britain is fully aware of the threat of energy security and climate change. It is moving from a self-sufficient energy supply to an era mainly relying on imports. According to the current consumption mode, it is estimated that 80% of Britain's energy must be imported by 2020. At the same time, climate change is imminent. The transition to a low-carbon economy has become the general trend of world economic development. In this context, a series of new concepts and policies such as "carbon footprint attaches great importance to building energy conservation", "low-carbon economy", "low-carbon technology", "low-carbon development", "low-carbon lifestyle", "low-carbon society", "low-carbon city" and "low-carbon world" have emerged. The result of the great changes in energy, economy and even values may pave a new way for gradually moving towards ecological civilization, that is, abandoning the traditional growth mode of the 20th century, directly applying the innovative technology of the new century, and realizing sustainable development through the low-carbon economic mode and low-carbon lifestyle. The development of low-carbon economy has become a global consensus. Governments of all countries attach great importance to the development of low-carbon economy

on march12,2010, a symposium on "low carbon road" was held in Beijing. He Qiang, a member of the National Committee of the Chinese people's Political Consultative Conference and a professor of the securities and Futures Institute of the Central University of Finance and economics, said that the development model of low carbon economy can not only save a lot of resources, but also reprocess through sorting plants to protect the environment, which is the long-term road for the world's economic development, At the same time, it is also the only way for China to change its economic development mode and adjust its economic structure. As an industry closely related to national macro policies, construction machinery is also seeking transformation under the environment of vigorously advocating energy conservation and emission reduction and developing low-carbon economy

According to a survey conducted by the Chinese Academy of Sciences, China is one of the countries with the most serious waste of natural resources in the world, ranking 56th among the 59 countries surveyed; According to statistics, China's energy efficiency is only 26.9% of that of the United States and 11.5% of that of Japan. With the pull of infrastructure construction, the market demand for construction machinery will continue to rise for some time in the future, and the high demand will bring more carbon dioxide emissions. As the second largest use industry of internal combustion engine products, although the scope of work is limited to the construction site, due to its high density, the emission is worse than that of automobiles, and the environmental pollution is more serious. Since the Copenhagen conference, the United States and the European common system have made an idea about the accuracy of experimental data. For future non construction machinery vehicles, tier4 standard has been adopted compulsorily since January 1, 2014. However, Tier1 standard is still implemented in China. Some energy and environmental protection experts have proposed that China should levy carbon tax from the 12th Five Year Plan, and it is unlikely to produce a large number of low-level construction machinery in the future. Under the environment that the international community attaches great importance to low-carbon, the transformation of the construction machinery industry to a low-carbon economy has become an irreversible trend, and existing enterprises in the industry have begun to take a low-carbon path
