Low-carbon environment-friendly little guardian composition

The so-called "low-carbon life" is to reduce the energy consumed in daily life as much as possible, thus reducing carbon dioxide emissions. Low-carbon life is an attitude, not an ability for ordinary people. We should actively advocate and practice a 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- 10 times that of coal-fired hydropower, and the price of wind power generation in some areas is higher than that of coal-fired hydropower; As a secondary energy, hydrogen energy is far from the commercialization goal of extracting clean energy such as wind energy and solar energy. Developing biofuels at the expense of consuming a large number of grain and oil crops has caused the prices of grain, meat and edible oil to rise to some extent. Globally, it is estimated that solar power generation will only reach 65,438+00% of the world's electricity supply by 2030, and the world's proven oil, natural gas and coal reserves will be exhausted in the next 40 years, 60 years and 65,438+000 years respectively. Therefore, one of the important meanings of "low-carbon economy" and "low-carbon life" is to save fossil energy consumption and provide time guarantee for the popularization and utilization of new energy in the next few decades when "carbon fuel civilization era" is in transition to "solar energy civilization era" (wind energy and biomass energy are both conversion forms of solar energy). Especially from the energy structure of China, low carbon means energy saving, and low carbon economy is based on low energy consumption and low pollution.

"Give up hobbies! The theme of Low-carbon Economy Environment Day 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, but also means guiding the public to reflect on which habitual consumption patterns and lifestyles are bad habits of wasting energy and increasing pollution, so as to fully tap the great potential of energy conservation and emission reduction in the service industry and consumers' lives. One of the important ways to turn to a low-carbon economy and a low-carbon lifestyle is to get rid of the hobby of "convenient consumption" at the expense of high energy consumption. " Convenience is a universal value in modern commercial marketing and consumer life. Many convenient consumption methods are inadvertently wasting huge energy. For example, according to the estimation of refrigeration technology experts, 70% of the electricity consumption of supermarkets is used for freezers, while the electricity consumption of open freezers is 20% higher than that of glass door freezers. Based on this calculation, an open freezer in a medium-sized supermarket consumes about 4% more than a year. 80,000 kWh, equivalent to consuming about 19 tons of standard coal, emitting about 48 tons of carbon dioxide and consuming about190,000 liters of clean water. There are about 800 large and medium-sized supermarkets and 6000 supermarket convenience stores in Shanghai. If glass door freezers are widely used in large and medium-sized supermarkets, customers can save about 452 1 10,000 kwh of electricity a year, which is equivalent to saving about10.8 million tons of standard coal and reducing carbon dioxide emissions by about 45,000 tons. In China, the annual per capita CO2 emission is 2.7 tons, but even if a white-collar worker in a city only has 40 square meters of living space, driving a car 1.6L after work and flying 12 times a year, the carbon emission will be 26 1 1 kg. 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 the code of conduct, then low-carbon life is a green lifestyle that we urgently need to establish.

Although "low-carbon life" is a new concept, it raises an old problem of sustainable development in the world, which reflects the concern for 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. Humans 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, the concept of "low-carbon life" is at least in line with the prudent principle of "preparing for a rainy day" and the psychology and ideal of pursuing perfection, so it is better to believe what it has than not, and the concept of "low-carbon life" is gradually accepted by all countries in the world. The emergence of a 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 gradually rises, people begin to care, have I done anything to reduce carbon today? In Badaling, Beijing, a carbon sink forest farm has begun to take 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, thus reducing carbon dioxide in the air. The idea of buying carbon sinks is more popular than driving less and turning on the air conditioner. At present, the main measures to slow down climate warming are to reduce emissions and increase 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 operability. More effective

[Edit this paragraph] Low carbon family

What kind of people can be regarded as "low carbon people" and what does "low carbon" mean? Simply put, "low carbon" is a living habit, and saving all kinds of resources around you is a natural habit. As long as you are willing to discipline 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 we can save more and not waste, we can also live a comfortable "low-carbon life". Since the Copenhagen Climate Change Summit opened on February 7th, 65438, it has been given various heavyweight titles such as "the most important conference in history" and "the conference that changed the fate of the earth". The 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 heat the earth. Over the past 200 years, with the deepening of industrialization, a large number of greenhouse gases, mainly carbon dioxide, have been emitted, which has led to global temperature rise and climate change. This is an indisputable fact. On February 8, 65438, the World Meteorological Organization released the report "Global Climate Situation in 2009" ahead of schedule, which pointed out that the recent 10 year was the hottest year in the world on record. In addition, global warming has caused Antarctic glaciers to begin to melt, which in turn has led to sea level rise. The latest survey published by Finnish and German scholars shows that by the end of this century, the sea level may rise by 1.9 meters, far exceeding previous expectations. If this continues, Tuvalu, a South Pacific island country, will probably become the first island country to disappear into the Wang Yang.

65438+ A study published by American media on February 5th pointed out that the earth fever has also caused a huge crisis to human health. First, allergies are getting worse. Studies show that with the gradual increase of carbon dioxide level and temperature, the flowering period is advanced, which increases the pollen yield and aggravates the spring allergy. Secondly, species are becoming more and more "pocket-sized". With the global temperature rising, the biological form is getting smaller and smaller, which has appeared in Scottish sheep. Third, kidney calculi has increased. Due to rising temperatures and dehydration, researchers predict that by 2050, there will be 2.2 million new patients with urinary calculi. Fourth, the outbreak of foreign infectious diseases, the increase of water environment temperature will make mosquitoes and plankton multiply, and dengue fever, malaria and encephalitis break out from time to time. Fifth, in summer, the lung infection is aggravated, the temperature rises and the cool wind decreases, which will aggravate ozone pollution and easily lead to lung infection. Sixth, algae flooding causes diseases, and the rising water temperature leads to the rapid reproduction of cyanobacteria, which will pollute natural lakes from municipal water supply system, thus causing diseases such as digestive system, nervous system, liver and skin.

[Edit this paragraph] Low-carbon life starts with details.

The global crisis caused by carbon dioxide has aroused people's sense of urgency. Even though countries around the world are still trying to reduce emissions, the concept of low carbon has almost been widely recognized. Low carbon refers to lower and lower greenhouse gas (mainly carbon dioxide) emissions. In this regard, Ren Guanping, secretary general of the Chinese Society of Environmental Sciences, told Life Times: "Energy conservation is the biggest carbon reduction." First of all, carbon reduction is mainly implemented in production, such as vigorously developing clean energy such as hydropower, nuclear power, wind energy and solar energy. Ren Guanping emphasized that it is everyone's responsibility to reduce carbon. For us, lifestyle describes everyone's "carbon footprint", and low-carbon life is a simple lifestyle. Ren Guanping also pointed out that low-carbon life can be reflected in all aspects of clothing, food, housing, use and transportation.

[Edit this paragraph] To enter a low-carbon life, the public needs to solve three puzzles.

With the increasing climate pressure, developing a low-carbon economy, building a low-carbon city and realizing a low-carbon life in an all-round way have gradually become the knowledge of all walks of life. However, in the process of interviewing many cities, some citizens and even government officials generally have three doubts about realizing a low-carbon life, which need to be solved by all parties.

Puzzle 1: Does realizing a low-carbon life mean lowering the living standard of urban residents? When interviewed by the author, some citizens think that realizing a low-carbon life is not only a great event, but also a good thing from the perspectives of saving resources and energy, protecting the environment and reducing carbon emissions. However, judging from the requirements of low-carbon life, it may reduce people's hard-won living standards. For example, while people's living standards are improving, they hope to improve their travel conditions by buying cars with large displacement or better performance, and they hope to buy bigger houses to improve their living conditions, which are obviously incompatible with low-carbon life. Wang Xianen, a professor at the School of Environment and Resources of Jilin University, and other experts believe that there is no conflict between fully realizing a low-carbon life and maintaining or improving people's living standards. Their common goal is to better improve people's living environment and conditions. The key is to find a combination point, explore a low-carbon sustainable consumption model, and minimize the use of products that consume more energy and reduce greenhouse gas emissions such as carbon dioxide while maintaining a high standard of living. Yang Yisheng, deputy director of the Fujian Provincial Government Development Research Center, said that low-carbon life is not a backward way of life, and engaging in a low-carbon economy will not necessarily reduce our quality of life. In a low-carbon economy, convenient transportation and comfortable and spacious houses can be guaranteed, and low-carbon technology can be used to solve these problems. For example, in cities, reclaimed water can be used to irrigate green space, renewable energy such as solar energy can be used for lighting and daily use, clean energy such as coalbed methane can be used as fuel for automobiles, and renewable energy heat pump technology such as sewage source, shallow water source, deep high-temperature underground water source and soil source can solve building heating. In Huihe Park, Shuozhou City, Shanxi Province, all the street lamps, underground lamps, courtyard lamps and lawn lamps used are powered by solar energy, and all the lamps are intelligently controlled to realize automatic lighting during the day and at night, saving about 800,000 kWh of electricity every year. While enjoying the physical and mental pleasure brought by urban construction, local citizens have virtually saved energy resources and reduced carbon emissions.

Puzzle 2: Low-carbon life is too far away from the daily life of urban residents. Will ordinary citizens be "willing but unable"? When interviewed, some citizens think that low-carbon life is just a theoretical idea, which is like an "unreachable" dream for them, too far away from their daily life. Some citizens also believe that low-carbon life is a systematic project, and it is difficult to achieve it by the citizens themselves. Instead of this, it is better to "muddle along" according to the daily lifestyle. When interviewed by the author, some experts believe that the living habits and consumption patterns formed by urban residents for a long time are really difficult to change in a short time. In this inertia life mode, the implementation of low-carbon life may also bring inconvenience. But none of these can be the reason why citizens refuse to live a low-carbon life. As long as people start from the details and have the determination and desire to change, a low-carbon life is completely achievable. Luo Xingbi, a staff member of WWF Changchun Project Office, said that in the action to stop global warming, not only the government and enterprises need to formulate effective countermeasures, but every ordinary person can play an important role. Reducing personal carbon footprint and cultivating a low-carbon lifestyle is not only the current social trend, but also the embodiment of personal social responsibility. Cui Shumin, Deputy Secretary-General of Taiyuan Municipal Government, picked up some documents from his desk and showed them to the author. These documents are printed on the back of waste paper. Not only that, they also make some blank paper into post-it notes, make full use of them and never waste them. "Global climate change affects our life and living environment, so more people need to participate in the practice of low-carbon lifestyle and contribute to environmental protection. Starting from each of us, starting from the changes of community residents and lifestyles. Citizens can do many things to achieve a low-carbon life, including reducing high-carbon energy consumption, green travel and recycling garbage. " Cui Shumin said. Zhang Huilian, a senior project officer at the Center for Sustainable Development Education of the Institute of Environment and Development, said: "Low-carbon life is actually very simple to do. The temperature of bath water can be reduced by 65438 0 degrees, and the carbon dioxide can be reduced by 35 grams per bath; Turn off the range hood after cooking, saving 10 minutes a day and 12 kwh a year. " The United Nations Environment Programme (UNEP) has put forward several suggestions on personal "low-carbon lifestyle", such as changing 45 minutes of exercise on an electric treadmill to jogging in a nearby park, which can reduce carbon dioxide emissions by nearly 1 1,000 grams; Don't use the washing machine to dry clothes, let clothes dry naturally, which can reduce the emission of 2300 grams of carbon dioxide; Turning off computers and monitors at rest and after work can not only save electricity, but also reduce the carbon dioxide emissions of these appliances 1/3 and so on.

Problem 3: Low-carbon life is a matter for urban residents. Can the government and relevant departments be "shopkeepers"? In the interview, the author also found that when talking about low-carbon life, the leaders of some cities' governments and relevant departments think that low-carbon life is mainly concentrated in the life field of citizens, which is their own business, mainly relying on citizens to change their ideas and practice. On the one hand, the government and relevant departments have no right to interfere, on the other hand, they are very powerless in changing the daily life style of citizens. Experts believe that the government and relevant departments are not only managers of social affairs, but also service providers of people's lives. Low-carbon life is not only the conscious behavior of citizens, but also the need for the government and relevant departments to create a low-carbon living environment. For example, building a low-carbon community, supporting "vein" industries such as garbage collection, and giving certain rewards to citizens who consciously practice a low-carbon lifestyle. , all have the role of "four or two" and form a good low-carbon lifestyle. During the author's interview, some citizens expressed the hope that the local government and relevant departments would provide some information services to realize a low-carbon life and guide their own life behavior by introducing some policies. Cities such as Taiyuan and Baoding have effectively guided citizens' lifestyles and consumption habits by formulating and implementing green standards involving various industries and issuing low-carbon life manuals. The successful practice of these cities also proves that in the process of realizing low-carbon life, the government and relevant departments can not only be "shopkeepers", but also promote the effective development of the whole work through their own efforts.

[Edit this paragraph] Low-carbon life-measures

Simple understanding, low-carbon life is to return to nature to carry out activities between people and nature, mainly changing the details of life from three aspects: saving electricity, saving solar terms and recycling, including the following low-carbon good living habits: advocating low carbon and caring for the earth.

1. Daily rice washing water can be used to wash hands and clean furniture, which is clean and natural.

2. Laying waste newspapers on the bottom of the wardrobe can not only absorb moisture, but also absorb the peculiar smell in the wardrobe;

3. Don't throw away the used mask paper. Using it to wipe the surface of jewelry, furniture or belt will not only shine, but also leave the fragrance of mask paper;

4. Dry tea residue, dry it to make a tea pillow, which is comfortable and helps to improve sleep.

5. Go out shopping, bring your own environmental protection bags, whether free or charged plastic bags, and reduce the use.

6. Bring your own drinking cup when you go out to reduce the use of disposable cups.

7. Use permanent chopsticks and lunch boxes, and try to avoid using disposable tableware.

8. Get into the habit of turning off the power supply of electrical appliances at will to avoid wasting electricity.

9. Try not to use refrigerators and air conditioners, and use electric fans or electric fans when it is hot.

After the re-creation of manual DIY, you will find that the original waste is also a treasure, so the home environment is healthy and full of creative little joy. "Low-carbon people" are using the changes of their own life details to prove that climate change is no longer just a concern of environmentalists, government officials and experts and scholars, but is closely related to each of us. Nowadays, advocating healthy living has become a trend. "Low-carbon life" is no longer just an ideal, but also a new lifestyle worth looking forward to.

There are a few points that are not easy to notice:

1. Replace the electronic alarm clock with the traditional clockwork alarm clock every day;

2. Turn off the computer power during lunch break and after work;

3. Turn off the lights and air conditioners once they are not used; Once the mobile phone is charged, unplug the charging plug immediately;

4. Choose to dry clothes and avoid using drum dryer; Use jogging in a nearby park instead of 45 minutes of exercise on the treadmill;

5. Replace the 60-watt bulb with an energy-saving lamp; Don't drive, ride a bike or walk.

6. When using the computer, try to use low brightness and open fewer programs to save electricity.

[Edit this paragraph] Low-carbon life-fashion life

The amount of food stored in the refrigerator should be 60% of the volume. Too much or too little food consumes electricity. There should be a gap of about 10 mm between food and refrigerator. Using several plastic boxes to hold water, making ice cubes in the freezer and putting them in the freezer can prolong the downtime and reduce the startup time.

The instantaneous current of air conditioner is large, and frequent switching consumes considerable power, which is easy to damage the compressor. Put the fan under the air conditioner and use the wind power of the fan to improve the cooling effect. Turn on the electric fan immediately after the air conditioner is turned on. You don't have to turn on the air conditioner all night at night, saving nearly 90% electricity. Set the air conditioner to dehumidification mode. At this time, even if the room temperature is slightly higher, it can make people feel cool and save electricity compared with refrigeration mode.

For the same long washing time, when the washing machine works in the weak gear, the motor starts more times, that is to say, using the strong gear actually saves electricity than the weak gear and can prolong the life of the washing machine. According to the rotation speed 1680 rpm (only applicable to turbine type) and dehydration time 1 min, the dehydration rate can reach 55%. Generally, dehydration does not exceed 3 minutes. Prolonging dehydration time is of little significance.

Dry food in the microwave oven is mixed with water, covered or wrapped with polypropylene plastic wrap before heating, or heated with heat-resistant glassware with cover. The amount of food heated or cooked at one time should not exceed 0.5 kg, and it is best to cut it into small pieces. When the quantity is large, it should be heated in different periods and stirred in the middle. Use "high firepower" as much as possible. In order to reduce the frequency of turning on and off the microwave oven when thawing food, food can be moved from the freezer to the freezer in advance and thawed slowly, so that the "cold energy" in frozen food can be fully utilized.

When the computer is not used for a short time, the energy consumption can be reduced to below 50% by turning on the "sleep" mode of the computer; Turn off unused programs and peripherals, such as speakers and printers; Do not let the hard disk, floppy disk and CD work at the same time; Reduce the brightness of the display appropriately. Special attention should be paid to the use of notebook computers: fully discharge the battery; Try not to use external equipment; Shut down temporarily unused equipment and interfaces; Close the screen saver; Reasonable shutdown mode: use "standby" when immediate recovery is needed, "sleep" when battery is used, and "shutdown" is not needed for a long time; When using the battery, under WindowsXP/VISTA, the CPU automatically reduces the frequency through SpeedStep technology, and the power consumption can be reduced by 40%.

The cooking time of large fire gas is shorter than that of small fire, which can reduce heat loss. But it is not advisable to let the fire exceed the bottom of the pot to avoid wasting gas. When the temperature is high in summer, don't cover the water before boiling, let the water with lower temperature than air exchange heat with the air, and then cover the water when the water naturally heats up to the air temperature, which can save gas. Before cooking, dry the water droplets outside the pan, try not to steam the food that can be cooked well, cook the food that is not easy to cook with pressure cooker or stainless steel pot, do not use oil fume, and heat the cooked food with microwave oven. It also helps to save gasoline.

Having a short meeting is also a kind of saving. Lighting, air conditioning and power for public address can be saved. Perfume that is about to expire can be sprayed on dried flowers stuffed in pillows, on washing water and on mopping the floor. Unplug any electrical appliances when they are not in use.

Try to use public transportation, make shopping plans when driving out, and try to buy them at one time. Walk more, ride a bike, take the light rail subway and drive less. Energy-saving during driving: avoid cold start, reduce idle time, avoid sudden speed change, choose appropriate gears to avoid high-speed and low-speed operation, change oil regularly, and keep the tire pressure appropriate without opening the window at high speed.

Use e-mail, MSN, QQ and other instant messaging tools more, and use fax printers and various trees less. 7. Eat less food with packaging bags and reduce the frequency of using packaging bags.

Take more buses. Carbon dioxide produced by transportation accounts for more than 30% of greenhouse gas emissions, and one of the best ways to reduce such emissions is to take buses. According to the data of American Public Transportation Association, public transportation saves nearly 5.3 billion liters of natural gas every year, which means that it can reduce carbon dioxide emissions by 6.5438+0.5 million tons.

Stick to small habits

Take less elevators 1 elevator, and reduce carbon emission by 0.2 18kg.

Turn on the cold air less 1 hour, and reduce the carbon emission by 0.62 1kg.

Blow less electric fans 1 hour, and reduce carbon emissions by 0.045kg.

Watch less TV 1 hour and reduce carbon emissions by 0.096kg.

Using less 1 hour bulbs will reduce carbon emissions by 0.04 1 kg.

Less driving 1 km will reduce carbon emissions by 0.22 kg.

Eating less fast food 1 time will reduce carbon emissions by 0.48kg.

Burning less paper money 1kg will reduce carbon emissions 1.46kg.

If 1kg garbage is lost less, the carbon emission will be reduced by 2.06kg.

Eating less 1kg of beef will reduce 13kg of carbon emissions.

Saving one degree of electricity will reduce carbon emissions by 0.638 kg.

Saving one degree of water will reduce carbon emissions by 0. 194kg.

Saving primary natural gas will reduce carbon emissions by 2. 1kg.

If we finish everything in one day, we can reduce our carbon emissions by 21.1.73kg per day.

If everyone in China can do everything every day, then we can reduce the carbon emissions by 296,422,200,000 kilograms every day, which is about 3x10.6 tons.

If everyone in the world can do everything every day, then we can reduce carbon emissions by 1058650000000kg every day, which is about 1. 1x 10 8 tons.

[Edit this paragraph] Low-carbon home life begins with decoration.

"Low carbon" is a very broad concept, and all ways to reduce carbon dioxide emissions can be collectively referred to as low carbon, including energy saving and emission reduction in industrial production, green design of buildings, and energy saving of automobiles. Low-carbon life can also save energy and reduce the emission of harmful substances at home.

Simplicity and generosity are most conducive to energy saving.

In recent years, simple design style has gradually become the dominant style in family decoration. Simple style is the most reasonable key factor of energy saving in home decoration. Of course, simplicity does not mean simplicity. As long as the design is comprehensive, the simple style is very suitable for modern decoration, especially for young people. And this design style can minimize the waste of materials in home decoration. Transparent design is now gradually accepted by more and more owners, which maintains ventilation and air circulation and greatly reduces energy waste.

Color returns to environmental protection and nature.

It used to be white at home. With the development of chemical industry, there are more and more colors at home. In fact, the use of color is also related to energy saving. Excessive use of dark colors such as red, green and purple will actually waste energy.

Especially in high temperature season, because dark paint absorbs heat, it is widely designed and used on home decoration walls, absorbing a lot of heat during the day, and using air conditioning at night will increase the energy consumption of the room.

Green building materials to create a low-carbon life

In the process of decoration, in fact, we can use lightweight partition materials such as light steel keel and gypsum board in some "zones" that don't pay attention to fastness, and try to use clay solid bricks, spotlights and aluminum alloy doors and windows as little as possible. In some designs, we can also consider giving up. For example, spotlights and light strips that most families only use occasionally are actually very expensive designs and are likely to become a great waste. Through material comparison, color matching and other means, it can completely replace spotlights and light belts.

In addition, when moving to a new house, try not to change the furniture that can continue to be used. Use more bamboo and rattan furniture. These materials are highly renewable and can also reduce the consumption of forest resources.
