Investigation and thinking on the annual carbon emission of an ordinary family

I. Background and significance of the research

165438+1A few days ago, my father always complained, "Why is it still so hot? It's nothing like autumn. " Grandma is also very worried: "the first frost of the 24 solar terms has passed, and it should be winter soon." Why is the weather so abnormal? " Dad's complaints and grandma's worries made me think: yes, according to the ancients, winter is coming, so why am I still wearing short sleeves? At this time, I remembered what the teacher said about global warming, which has seriously affected the survival of human beings, and those lovely penguins have been greatly reduced because of climate warming. So what are the causes of global warming, and how can we make the earth's climate normal?

Through online inquiry, it is known that the main cause of climate warming is the excessive emission of greenhouse gases (carbon dioxide). I also learned a new term "carbon emission", which is the general name or abbreviation of greenhouse gas emission. The most important gas in greenhouse gases is carbon dioxide, so the word carbon is used as a representative. Although it is not accurate, as the fastest way for people to understand it, it is simply to understand "carbon emissions" as "carbon dioxide emissions". I also learned that according to a research report of the International Energy Agency (iea), the carbon dioxide emission in 20 10 was 30.6 billion tons, the highest level in history, and the agency warned that the annual greenhouse gas emission should not exceed 32 billion tons. So it is urgent to control the growth of global carbon emissions, so what should we do as small citizens of the earth?

Low-carbon life should start with me and my home. First, make statistics on the composition of carbon emissions of my family (there are three people in our family) in one year, and then analyze how to reduce the carbon emissions of my family. Quote a public service advertisement of Wenzhou Radio Station: "No matter how small the power is, it is also a kind of support." Two. Research methods.

In the process of research, I will use the methods of searching information, sampling survey, statistics and calculation.

Three. The process of research.

1 (Search for information and find a method to calculate personal carbon emissions.

First of all, I want to think about: which aspects of our family will produce more carbon dioxide in daily life, and how to calculate the amount of carbon dioxide produced.

In order to solve these two problems, I searched online and was surprised to find a calculator that can calculate personal carbon emissions. It is supervised by Beijing Forestry Carbon Sequestration Office. The formula in the personal carbon emission calculator developed by the calculator is based on the formula formulated by the United Nations and some environmental protection organizations, and uses the local statistical data and conversion coefficient in China, which makes the calculation more in line with China's national conditions and more accurately reflects a person's actual carbon emission, and lists our basic necessities and conversion coefficients.

For example, clothing (the number of clothes purchased, the number of washing powder used), food (the number of smoking, the number of drinking white wine, the number of drinking beer, the consumption of meat and food), housing (electricity, gas, natural gas, coal burning, central heating, wood for decoration, aluminum for decoration), and transportation (planes, ships, trains, subways, buses). And each item of carbon dioxide consumed has a corresponding calculation formula.

Wow, that's great ~ I only need to count the consumption of goods in our family for more than one year, and I can substitute it into the formula of carbon emission calculator to calculate the carbon dioxide emission of the whole family for one year.

Here are some calculation methods:

Carbon dioxide emission of household electricity (kg) = power consumption × 0.785;

CO2 emission from driving (kg) = fuel consumption increase × 0.785;

Aircraft carbon dioxide emissions (kg):

Short distance: within 200 km = km × 0.275;

Midway trip: 200 to1000 km = 55+0.105× (km-200);

Long-distance travel: over 1000 km = km ×0. 139.

Carbon dioxide emission of trains = km ×0.04

Carbon dioxide emission of meat (kg) = kg × 1.24.

(See/ZT/2009/ChooseEarth/tanzuji.htm for details) 2. Collect relevant data and calculate household carbon emission projects by classification.

The carbon emission calculator covers five aspects: clothing, food, housing, transportation and use, with 26 items in total. After careful analysis, nine items have not been consumed by our family (including house decoration and smoking), and the following items are related to our family: the number of clothes purchased, the amount of washing powder, the amount of liquor, and the number of items related to our family.

For the convenience of statistics, I divide my carbon emission projects into the following three categories: (1) "Easy to count and clear" data can be directly collected according to related bills and dashboards. For example, natural gas, electricity consumption, the mileage of my dad's car, the mileage of flying, the mileage of taking the train, the mileage of long-distance buses, and the number of clothes bought are all calculated on an annual basis. Data were collected by consulting natural gas and electricity bills, as well as surveys and surveys in automobile odometer.

Then substitute the obtained one-year correlation into the formula, and the calculation result is shown in table 1:

The electricity consumption is 7320 degrees 7027.2, calculated by electricity meter, natural gas is 86 cubic meters 6 1.06, calculated by gas meter, automobile mileage 10000 kilometers 156 1 calculated by odometer, and the mileage of flying is 2856 kilometers, 396.98, and the mileage from Wenzhou to Beijing is 9/kloc-.

Little egrets are going back and forth on the beach. The number of clothes purchased was 7 1 454.4. Mom bought 28 pieces and Dad bought them.

18 yuan, I bought 25 yuan, a total of 9604.4.

(Table 1)

(2) The data of "scattered incidents that are not easy to refer to" will be recorded regularly this month, and sampling survey will be adopted. As far as possible, take appropriate individual data as a sample of the whole year, and then take this sample as the average monthly usage, so as to estimate the whole year (this is because the research time of this paper is limited). For example, on the day of 1 65438+1October12-65438+February 1kg, the monthly consumption of washing powder is about1kg, so the carbon emission calculated according to the above formula is 0.72kg, which is 0.72× 60 for the whole year.

The consumption of washing powder, grain and paper products is counted monthly, as shown in Table 2.

(kg) (kg) Consumption of washing powder 1kg 0.72 8.7 Consumption of grain 45kg 42.3 507.6 Consumption of paper products 5kg 17.5 2 10, totaling 726.3.

(Table 2)

(3) For most items of food, transportation and use, more detailed records and statistics are needed. I actually keep a diary for one month (165438+1October12-65438+February 1 1). Through this,
