The concept of low-carbon life The so-called "low-carbon life" means that the energy consumed in daily life should be reduced as much as possible, so as to reduce the emission of carbon dioxide. Low-carbon life is an attitude, not an ability, for ordinary people. We should actively advocate and practice low-carbon life, and pay attention to saving electricity, water, oil and solar terms. In addition to planting trees, some people buy goods with short transportation mileage. Some people insist on climbing stairs in various ways, some of which are interesting and some of which are inevitably troublesome. But people who care about global warming have actually brought carbon dioxide reduction into their lives.

the ideal form of "low carbon economy" is to fully develop "sunshine economy", "wind energy economy", "hydrogen energy economy" and "biomass energy economy". But at present, the cost of solar power generation is 5-1 times that of coal-fired hydropower, and the price of wind power generation is higher than that of coal-fired hydropower in some areas; As a secondary energy, hydrogen energy is still far from the commercialization goal of extracting clean energy such as wind energy and solar energy. The development of biofuels at the expense of consuming a lot of grain and oil crops has caused the price of grain, meat and edible oil to rise to some extent. From a global perspective, it is estimated that solar power generation will only reach 1% of the world's electricity supply by 23, and the world's proven oil, natural gas and coal reserves will be exhausted in the next 4, 6 and 1 years respectively. Therefore, one of the important meanings of "low-carbon economy" and "low-carbon life" is to save the consumption of fossil energy and provide time guarantee for the popularization and utilization of new energy in the next few decades when the "carbon fuel civilization era" transits to the "solar energy civilization era" (wind energy and biomass energy are the conversion forms of solar energy). Especially from the energy structure of China, low-carbon means energy saving, and low-carbon economy is an economy based on low energy consumption and low pollution.

"give up hobbies! The theme of Environment Day for Low-carbon Economy reminds people that "low-carbon economy" not only means that the manufacturing industry should speed up the elimination of backward production capacity with high energy consumption and high pollution, and promote scientific and technological innovation of energy conservation and emission reduction, but also means guiding the public to reflect on which accustomed consumption patterns and lifestyles are bad habits of wasting energy and increasing pollution, so as to fully explore the great potential of energy conservation and emission reduction in the service industry and consumer life. One of the important ways to turn to a low-carbon economy and low-carbon lifestyle is to get rid of the hobby of "convenient consumption" at the expense of high energy consumption. "Convenience" is a popular value in modern commercial marketing and consumer life. Many convenient consumption methods are wasting huge energy inadvertently. For example, according to the estimation of refrigeration technology experts, 7% of the electricity consumption of supermarkets is used for freezers, while the electricity consumption of open freezers is 2% higher than that of glass door freezers. From this calculation, an open freezer in a medium-sized supermarket consumes about 4% more a year. 8, kWh is equivalent to consuming about 19 tons of standard coal, emitting about 48 tons of carbon dioxide and consuming about 19, liters of clean water. There are about 8 large and medium-sized supermarkets and 6 supermarket convenience stores in Shanghai. If glass door freezers are widely used in large and medium-sized supermarkets, customers only need to lift a finger when shopping, which can save about 45.21 million kWh of electricity a year, which is equivalent to saving about 18, tons of standard coal and reducing carbon dioxide emissions by about 45, tons. In China, the annual per capita CO2 emission is 2.7 tons, but even if a white-collar worker in a city has only 4 square meters of living space, driving a 1.6L car to get off work and flying 12 times a year, the carbon emission will be 2,611 kilograms. From this point of view, energy conservation and emission reduction is imperative. If environmental protection concepts such as protecting the environment, protecting animals and saving energy have become codes of conduct, low-carbon life is a green lifestyle that we urgently need to establish.

Although "low-carbon life" is a new concept, it is an old problem of sustainable development in the world, which reflects the concern about the future caused by climate change, and the world is increasingly aware of this problem. Climate problems such as global warming make human beings have to consider the current ecological environment. Human beings realize that excessive carbon emissions in the process of production and consumption are one of the important factors that cause climate problems, so to reduce carbon emissions, some consumption and production activities should be optimized and restrained accordingly. Although some scholars still have different views on the causes of climate change, because the concept of "low-carbon life" at least conforms to the cautious principle of "preparing for a rainy day" and the psychology and ideal of pursuing perfection, it is better to believe what it has than to believe what it has, and the concept of "low-carbon life" is gradually accepted by all countries in the world. The emergence of low-carbon life not only tells people what you can do to reduce carbon, but also tells people what you can do. When this lifestyle is gradually emerging, people begin to care, have I done anything to reduce carbon today? In Badaling, Beijing, a carbon sink forest farm has taken shape. If you want to offset your carbon emissions, you can come here to buy carbon sinks or plant trees. Forestry carbon sinks absorb and fix carbon dioxide in the atmosphere and release oxygen through afforestation, forest management and vegetation restoration, so as to reduce carbon dioxide in the air. The idea of buying carbon sinks is welcomed by more people than driving less and turning on air conditioners less. At present, the main measures to slow down climate warming are reducing emissions and increasing foreign exchange. Compared with emission reduction measures, forestry carbon sequestration measures have become an important means to slow down climate warming because of their low cost, multiple benefits and easy operation.

what kind of people can be regarded as "low-carbon people" and what does "low-carbon" mean? To put it simply, "low carbon" is a living habit, and it is a natural habit to save all kinds of resources around you. As long as you are willing to take the initiative to restrain yourself and improve your living habits, you can join in. Of course, low-carbon doesn't mean that you should be frugal and give up some enjoyment of life. As long as you can save more and don't waste, you can also live a comfortable "low-carbon life". Since its opening on December 7th, the Copenhagen Climate Change Summit has been crowned with various heavyweight titles, such as "the most important conference ever" and "the conference that changed the fate of the planet". This conference tried to establish a global framework for greenhouse gas emissions, and it also made many people deeply reflect on the current production and lifestyle of human beings. Greenhouse gases have caused the earth to have a fever for more than 2 years. With the deepening of industrialization, a large number of greenhouse gases, mainly carbon dioxide, have been discharged, which has caused the global temperature to rise and the climate to change. This is an indisputable fact. On December 8th, the report "Global Climate in 29" released in advance by the World Meteorological Organization pointed out that the last 1 years were the hottest in the world on record. In addition, global warming has also caused Antarctic glaciers to begin to melt, which in turn led to sea level rise. The latest survey published by Finnish and German scholars shows that the sea level may rise by 1.9 meters by the end of this century, far exceeding previous expectations. If this development continues, Tuvalu, a South Pacific island country, will probably be the first island country to disappear into the Wang Yang. A study published by the American media on December 5 pointed out that the earth's fever has also caused a huge crisis to human health. First, the allergy is aggravated. Studies show that with the gradual increase of carbon dioxide level and temperature, the flowering period comes ahead of schedule, which increases the pollen production and aggravates the allergy in spring. Secondly, the species are becoming more and more "pocket-sized". With the global temperature rising, the biological form is getting smaller, which has already appeared in Scottish sheep. Third, the kidney calculi has increased. Due to the rising temperature and dehydration, researchers predict that by 25, there will be 2.2 million new patients with urinary calculi. Fourth, the outbreak of exotic infectious diseases, the increase of water environment temperature will make mosquitoes and plankton multiply, and dengue fever, malaria and encephalitis will break out from time to time. Fifth, in summer, the lung infection is aggravated, the temperature is increased, and the cool wind is reduced, which will aggravate ozone pollution and easily lead to lung infection. Sixth, algae flooding causes diseases, and rising water temperature leads to the rapid proliferation of cyanobacteria, which will be polluted from municipal water supply system to natural lakes, thus causing diseases of digestive system, nervous system, liver and skin.
