Section 1 Low-carbon, Low-carbon Life and Low-carbon Lifestyle
What is "low carbon"
Low carbon, English for "low carbon", means reducing (reducing) greenhouse gas (mainly carbon dioxide) emissions.
What is a "low carbon life"
Low-carbon life is to reduce the consumption of various activities in social life, thus reducing carbon emissions, especially carbon dioxide. Low-carbon life is an attitude and an idea for ordinary people. We should actively advocate and practice a low-carbon life, pay attention to saving electricity, oil and solar terms, and start from scratch.
What is a "low carbon lifestyle"
The low-carbon lifestyle should start from the details, abandon the bad habits of wasting resources and increasing pollution, and abandon the bad habits of "face consumption" and "luxury consumption" at the expense of increasing energy consumption and greenhouse gas emissions. In 2008, the United Nations Environment Programme released a report in World Environment Day, giving suggestions on "low-carbon lifestyle" and instructing people how to contribute to energy conservation and emission reduction from small things in daily life.
Section 2 Low-carbon Life and Low-carbon Economy
Low-carbon economy is an economic model based on low energy consumption, low pollution and low emission, and it is another great progress of human society after agricultural civilization and industrial civilization. The essence of low-carbon economy is to use energy efficiently, develop clean energy and pursue green GDP. The core is the innovation of energy technology and emission reduction technology, the innovation of industrial structure and system, and the fundamental change of human survival and development concept.
The background of "low-carbon economy" is the severe challenge of global warming to human survival and development. With the continuous growth of global population and economic scale, environmental problems caused by energy use and their causes have been continuously recognized by people, not only the harm of smog, photochemical smog and acid rain, but also the global climate change caused by the increase of carbon dioxide (CO2) concentration in the atmosphere has been confirmed as an indisputable fact.
In this context, a series of new concepts and policies such as "carbon footprint", "low-carbon economy", "low-carbon technology", "low-carbon development", "low-carbon lifestyle", "low-carbon society", "low-carbon city" and "low-carbon world" came into being. The result of great changes in energy, economy and even values may be a new way to gradually move towards ecological civilization, that is, abandoning the traditional growth model of the 20th century, directly applying innovative technologies and mechanisms in the new century, and realizing social sustainable development through a low-carbon economic model and a low-carbon lifestyle.
As a frontier economic concept with extensive sociality, low-carbon economy has no conventional definition. Low-carbon economy also involves a wide range of industrial fields and management fields.
The ideal form of "low carbon economy" is to fully develop "sunshine economy", "wind energy economy" and "hydrogen 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 the consumption of fossil energy and provide time guarantee for the popularization and utilization of new energy in the next few decades when "carbon fuel civilization era" transits to "solar energy civilization era". 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.
"Get rid of 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 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, the open freezer of a medium-sized supermarket consumes about 48,000 kWh more than one year, which is equivalent to about 19 tons of standard coal, about 48 tons of carbon dioxide, and 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.
The second important way to turn to a low-carbon lifestyle is to get rid of the consumption hobby of using disposable products. The uncontrolled use of plastic bags is one of the most typical hobbies of people for many years. It is necessary to make quitting this hobby become people's conscious behavior, and let the public understand that the significance of "limiting plastics" lies in curbing white pollution, which is only a "one-dimensional" environmental science consciousness. In fact, the significance of "limiting plastics" is to save the source of plastics-petroleum resources and reduce carbon dioxide, which is a "related" awareness of energy conservation and environmental protection. According to the calculation in the National Handbook of Energy Conservation and Emission Reduction issued by the Ministry of Science and Technology of China, the reduction of plastic bags by 10% can save about10.2 million tons of standard coal and 3 1 10,000 tons of carbon dioxide. Relevant environmental awareness can not only guide the public to understand that "limiting plastics means saving oil and energy", but also guide the public to realize that "saving water is also saving energy" (that is, saving the electricity consumption of urban water production and water supply) and the relationship between changing the consumption hobby of using disposable products and saving energy, reducing carbon emissions and coping with climate change.
The third important way to turn to a low-carbon lifestyle is to get rid of the hobby of "face consumption" at the expense of consuming a lot of energy. In the first quarter of 2009, the fastest-growing car sales in China were luxury cars, among which high-end large-displacement BMW imported cars increased by more than 82% year-on-year, and large-displacement multi-functional sports car SUV increased by 48.8% year-on-year. In contrast, many developed countries are willing to use small cars and small displacement cars. Advocating a low-carbon lifestyle is not to oppose cars entering the family, but to advocate the moderate use of private cars. The penetration rate of private cars in Japan is 80%, but travel is not entirely dependent on private cars. In Tokyo, private cars generally travel 3000 to 5000 kilometers a year, while private cars in Shanghai generally travel 18000 kilometers a year. The unrestrained use of private cars by domestic people has become a hobby of conspicuous consumption life. In front of key schools in some cities, one or two hundred private cars pick up and drop off children, blocking the surrounding roads. Because people unilaterally understand the meaning of "modern lifestyle" as "enjoying more convenience provided by electrification and automation", daily life is increasingly dependent on power technology systems with high energy consumption. Often the short distance of several hundred meters or the stairs of several floors are driven by motor vehicles and elevators. On the other hand, people consume more and more high-calorie foods such as livestock and poultry meat and oil at the expense of energy consumption and greenhouse gas emissions. The incidence of obesity has also increased. Some weight-loss groups in cities prefer to consume their weight in artificial environments that consume electricity, such as air-conditioned gymnasiums and electric treadmills. The environmental cost is to increase greenhouse gas emissions.
Calculate your carbon footprint in the third quarter
What is a "carbon footprint"
"Carbon Footprint" comes from the English word "carbon footprint", which means the "carbon consumption" of a person or group. It is an index to measure the environmental impact of carbon dioxide emissions produced by a country, region, company, family or individual due to daily energy consumption.
A person's carbon footprint can be divided into the first carbon footprint and the second carbon footprint. The first carbon footprint is carbon dioxide directly emitted by fossil energy. For example, a person who often travels by air will have more first carbon footprint, because flying will consume a lot of fuel and emit a lot of carbon dioxide. The second carbon footprint is the carbon dioxide indirectly emitted by various products. For example, a bottle of ordinary bottled water will bring a secondary carbon footprint due to the carbon emissions generated during its production and transportation.
Carbon footprint involves many factors and can be measured by a specially designed "carbon footprint calculator". For example, if you use 100 kwh of electricity, that means you emit about 78.5 kilograms of carbon dioxide; You consumed 100 liter of gasoline and emitted about 270 kilograms of carbon dioxide. The greater your carbon footprint, the greater your responsibility for global warming.
Knowing your "carbon footprint" in daily life, you can try to live by reducing your "carbon footprint". For example, reduce unnecessary consumption of household appliances; Travel by bus; Choose local products first when buying goods; Even when eating and cooking, choose a cooking method that reduces the "carbon footprint". Taking potatoes as an example, baking potatoes in an oven produces more carbon dioxide than cooking potatoes in a pot, and cooking potatoes in a pot produces more carbon dioxide than cooking potatoes in a microwave oven.
Is there any positive and feasible way to reduce the "carbon footprint" left by life and activities? This is the "carbon neutral" environmental protection action that became popular in the west.
(2) What is "carbon neutrality"
The so-called "carbon neutrality" means that people (including units, enterprises and individuals) calculate the carbon dioxide emissions directly or indirectly generated by their daily activities (production), and then plant trees to absorb these emissions, or calculate the economic costs required to offset these carbon dioxide, and then individuals pay the fees to specialized enterprises or institutions to offset the corresponding carbon dioxide in the atmosphere through tree planting or other environmental protection projects. Obviously, "carbon neutrality" is self-examination and self-discipline after people reflect on the reality of global warming, and it is a positive action after the residents of "global village" wake up. Dealing with the excessive discharge of carbon dioxide and major pollutants is not only the responsibility of the government, but also the responsibility of every enterprise and every citizen.
Learn to calculate the family's carbon footprint.
The "carbon footprint" of a family is the "carbon" emission of every household in daily consumption. You can calculate your "carbon footprint" by the following formula:
1, household electricity consumption
According to the average carbon emission when generating electricity (in fact, the carbon emission generated by using clean energy such as wind power or hydropower will be lower than that generated by using thermoelectric). Carbon dioxide emission (kg) = power consumption ×0.785.
Step 2 transport
① Driving: Because the fuel consumption of cars with the same distance and different displacement is different, it is necessary to convert the distance into fuel consumption according to the fuel consumption of cars to calculate the carbon emissions, and small displacement cars have less carbon emissions at the same distance. Therefore, it is necessary to vigorously promote small-displacement energy-saving and environment-friendly vehicles.
Emissions of carbon dioxide (kg) = litres of oil consumption ×2.7.
② Flight: calculated according to the average emission of passengers on the plane. In fact, because business class and first class occupy more space, the emissions should be higher than economy class.
Short-distance travel within 200 kilometers: carbon dioxide emission (kg) = flight kilometers × 0.275;
200 ~ 1000 km: CO2 emission (kg) = 55+0. 105× (flight kilometers-200);
/kloc-long-distance travel over 0/000 km: CO2 emission (kg) = flight km ×0. 139.
3. Household gas:
① Natural gas: CO2 emission (kg) = natural gas usage × "carbon intensity coefficient" 0. 19.
② Liquefied petroleum gas: carbon dioxide emission (kg) = usage of liquefied petroleum gas × "carbon intensity coefficient" 0.2 1.
4. Domestic tap water:
It takes 0.67 ~ 1. 1.5 kwh to produce a ton of tap water. According to the average power consumption, carbon dioxide emission (kg) = tap water usage ×0.9 1.
(4) Are you carbon neutral?
"Carbon neutrality" is a scientific and healthy life concept and lifestyle. On the one hand, adopt a "low-carbon lifestyle" to reduce carbon emissions; On the other hand, the balance is achieved through certain carbon offset measures. A tree can absorb 18.3 kg of carbon dioxide a year. Number of trees planted (plant) = carbon dioxide emission (kg) ÷ 18.3.
The second chapter is the golden idea of low-carbon life
Section 1 Washing and Finishing of Clothes
1, water saving of washing machine
Jindianzi 1
The washing time depends on the kind of clothes and the degree of dirt. Generally speaking, synthetic fibers, wool and silk fabrics can be washed for 3 to 4 minutes, cotton and linen fabrics for 6 to 8 minutes, and dirty clothes for 65,438+00 to 65,438+02 minutes.
Golden idea 2
In the same long washing cycle, the number of blades in "softening" mode is more than that in "standard" mode, and the motor will be started repeatedly. The starting current of the motor is 5-7 times of the rated current, and "standard washing" is more energy-saving.
Golden idea 3
Dehydration after washing can be completed within 2 minutes. When clothes are dehydrated for one minute at the speed of 1680 rpm, the dehydration rate can reach 55%, but the dehydration rate is slightly improved by prolonging the time.
Section 2 Selection, Storage and Cooking of Food

Chapter 3: Three puzzles to be solved in entering a low-carbon life.
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 many cities, some citizens and even government officials generally have three major doubts about realizing a low-carbon life, which need to be solved by all parties.
Confusion 1: Does achieving a low-carbon life mean reducing emissions?
What is the living standard of urban residents?
Some citizens believe that from the perspective of saving resources and energy, protecting the environment and reducing carbon emissions, achieving a low-carbon life is not only a major event, but also a good thing. 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.
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.
