The concept that must be understood in the 21st century -carbon footprint

  Among the nature, full of various footprints, and carbon footprints are one of the invisible and invisible feet.Traces can measure the number of carbon dioxide. The so -called carbon footprint, English is Carbon Footprint, refers to the collection of greenhouse gas emissions caused by corporate institutions, activities, products or individuals through transportation, food production and consumption, and various production processes. Simply put, it is the "carbon consumption" of a person or group.

  Oil, coal, wood and other materials in our lives are composed of carbon elements, and the more these materials are consumed. The more carbon emissions, the more serious the global warming is caused.

  So, how to calculate the "carbon footprint" in life? First of all, we need to clarify the rules of carbon footprint calculation, that is, the public daily consumption → carbon dioxide emissions → carbon compensation. Secondly, after finishing the project share of daily consumption, the second step needs to complete the calculation of carbon emissions of each project. So what are the calculation methods?

Calculation method

Carbon dioxide emissions (kg) = power consumption number × 0.785 × renewable energy power correction coefficient

Carbon dioxide emissions (kg) = fuel consumption liters × 0.785

Carbon dioxide emissions (KG) by plane

Short -distance travel: within 200 kilometers = kilometers × 0.275 × The per capita carbon emissions of the unit cabin of the aircraft

Traveling halfway: 200-1000 kilometers = 55+0.105 × (kilometers -200)

Long -distance travel: more than 1000 kilometers = km × 0.139

  Finally, after counting the basic carbon emissions, it is necessary to calculate the carbon emissions in a carbon compensation, that is, the "carbon compensation forest" method. According to the State Forestry Administration, a tree can absorb and store 4-18 kg carbon dioxide each year. Based on the age of 50 years, it can reach up to 90 kg of carbon dioxide.

  So, if you say that your journey is 1,000 kilometers, your carbon emissions are 189 kg, you need to plant two trees to offset; based on this kind of calculation, if you consume 100 liters of gasoline by car, your self -driving car consumes 100 liters of gasoline, yours Carbon emissions are 270 kg, and three trees are required to offset ...

healthy lifestyle

"Low carbon is good related to our life"

  So, what are the benefits of understanding the concept of carbon footprints? In this regard, we can sort out from the following two perspectives:

First of all, it is about changes in enterprises and industries. With the release of various orientation documents, such as the "Twelfth Five -Year Plan" Special Plan for the Development of Climate Change Science and Technology Development "is clearly proposed that it is necessary to promote my country's slowdown and adapting to climate change technology Innovation and application, support the development of low -carbon economy, and support the goals of the GDP carbon dioxide emissions during the "Twelfth Five -Year Plan" period and 2020.

  Therefore, more and more companies have also begun to pay attention to low -carbon manufacturing, of which, naturally need to use the calculation of relevant carbon footprint and carbon emissions to reduce the GHG emissions of the entire life cycle of the product. The method is naturally not good.

Window window

"Window with better performance"

  Of course, there is another way to reduce the amount of air conditioning, that is, a window with better sealing performance. High -sealed performance insulation and energy -saving windows can keep the indoor comfortable temperature without using or without air conditioning. This will not only reduce the damage to the human body for long blowing air conditioners, but also can save energy and tariffs.

  More importantly, the natural comfort that this kind of window brings people's lives is incomparable to the environment created by air conditioning or other equipment, so people who are willing to choose more ecological life will choose windows with better performance to create a space to create space A more livable environment, this has never reduced personal carbon emissions.
