Carbon footprint（Carbon Footprint）It is used to measure the carbon dioxide emissions directly or indirectly caused by individuals, organizations, products or countries within a certain period of time.The calculation of carbon footprint covers the emissions of products or services in the whole life cycle from production, transportation, final use to waste disposal.This comprehensive assessment method enables us to more accurately understand and evaluate the impact of human activities on the environment.The introduction of the concept of carbon footprint aims to remind people of the urgency of tackling climate change.By calculating and understanding the carbon footprint of individuals or organizations, we can help people identify and implement strategies to reduce greenhouse gas emissions, thereby combating global warming.
In June 2024, the Ministry of Ecology and Environment, the Ministry of Finance, the People's Bank of China and other 15 departments jointly issued the Implementation Plan on Establishing a Carbon Footprint Management System.The Plan points out that the carbon footprint management system will be initially established by 2027;By 2030, the carbon footprint management system will be more perfect and the application scenarios will be more abundant.[6]
Carbon footprint, which represents the“carbonConsumption "."Carbon" refers to oil, coal, wood and other carbon elementsnatural resources。The more "carbon" is consumed, the culprit of global warming“carbon dioxide”The more they are manufactured, the larger their "carbon footprint" will be;On the contrary, the "carbon footprint" is smaller.The supply chain of manufacturing enterprises generally includes procurement, production, warehousing and transportation, in which warehousing and transportation will generate a large number ofcarbon dioxide。
A carbon footprint is historically defined as"the total set ofgreenhouse gas(GHG）Emissions caused by an organization, event, product or person.Greenhouse gas emission channels mainly include:Transportation, food production and consumption, energy use and variousProduction process。Usually used for all greenhouse gas emissionsCarbon dioxide equivalent To represent.
Carbon footprint(CO2 footprint)[2], Carbon Footprint in English, refers to enterprises, activities, products or individuals through transportation, food production and consumption and variousProduction processCaused byGreenhouse gas emissionsCollection of.It describes the impact of a person's energy awareness and behavior on the nature, and calls on people to start from themselves.Some enterprises have begun to practice the environmental protection concept of reducing carbon footprint.

Calculate your own "carbon footprint"
idea
Daily public consumption - carbon dioxide emissions - carbon compensation
Change lifestyle, abandon all kinds of "high carbon" life, and advocate "low carbon" life.
Long distance travel: more than 1000 kilometers=kilometers × 0.139.
Number of compensation trees after conversion
Carbon footprint
For example, if you travel 2000km by air, you will emit 278kgcarbon dioxideFor this reason, three trees need to be planted to offset;If 100 kilowatt hours of electricity is used, 78.5 kilograms of carbon dioxide will be emitted.To do this, a tree needs to be planted.
If it is not compensated by planting trees, it can be based on the international general carbon sinkprice level For each ton of carbon dioxide emitted, the compensation is 10 dollars.With this money, you can invite others to plant trees.
According to the absorption of 111Kg by fir in 30 yearscarbon dioxideTo calculate how many trees need to be planted to compensate.
Carbon footprint calculation
First, there are several methods to calculate carbon footprint:
Life cycle analysisIt is a bottom-up calculation method for products and their "from beginning to end" process. The calculation process is detailed and accurate.
IPCC carbon emission method isthe United NationsThe Guidelines for Greenhouse Gas Inventories prepared by the Climate Change Commission take into full consideration the greenhouse gas emissions in the calculation process.
Input and outputMethod is a top-down calculation method, which uses input and output to calculate, but the calculation results are not accurate.
More than one method is available to the public, which depends on how people use it.Like thisWorld mapandU.S. Department of StateThe carbon footprint per capita and the total emissions of each country (or other advancedWork team, organizations, etc.), and can separate the individual emissions of residents from the group.The calculation from bottom to top is just like the above example of the carbon footprint of your own car, summarizing the carbon emissions attributed to individual actions.
Take the carbon footprint of your own car as an example: the first method estimates all carbon emissions, from the mining of raw materials for cars (including all metals, plastics, glass and other materials used to manufacture cars) to the entire life cycle of car production, driving and disposalcarbon dioxidedischargeequivalent。The second method onlyComputational manufacturing, driving and disposal of vehiclesfossil fuelCarbon emissions.
Calculator
Carbon footprint
In 2013, everything has its own carbon footprint, and each item can be measured in different ways, but it is not only for carbon dioxide (although it is the most common relative to other greenhouse gases), other greenhouse gases include (but are not limited to):methane, ozone,Nitrous oxide，Sulfur hexafluoride, hydrofluorocarbons, perfluorocarbons andChlorofluorocarbonsEtc.In view of this, most carbon footprint calculations in the United States include all applicable gases, because these are conducive to understanding and understandinggreenhouse effectAndGlobal warming。This is a rather complicated calculation. Different individuals will have different variables. The calculation of carbon footprint includes everything used for electricity, home building, transportation (including traveling by car, plane, railway and othersPublic transport）And all the energy usedconsumables。Many of the above personal factors can be calculated separately (such as personal carbon footprint, from home, travel, food, etc.).Once you understand your carbon footprint and where it comes from (perhaps more important), you can start to reduce it;There are many ways to generate a carbon footprint, but there are always ways to reduce it.

As more and more enterprises begin to pay attention to low-carbon manufacturing to cope with the pressure from the government, society and the public, and demonstrate their own social responsibility.Many excellent enterprises in the industry start from the product source design to reduce the overall productlife cycleGHG emissions.
According to the data analyzed by CQC, the use of high energy consuming equipment in the paint industry in 2013 and the high carbon emissions of some raw materials are the main reasons for the high carbon emissions of most brand paint products.
"Twelfth Five Year Plan" National Science and Technology Development for Climate ChangeSpecial planning》Officially released.The Special Plan clearly proposes to promote national mitigation andAdaptation to climate changeTechnological innovation and application, support the development of low-carbon economy, support the units during the "12th Five Year Plan" period and 2020gross domestic productcarbon dioxideEmission target.It is believed that with the further implementation of relevant national policies, more and more companies will begin to accept carbon footprint assessment and certification of products, which will also become assessment enterprisesLow carbon and environmental protectionsocial value New coordinates of.
According to the information of E-Carbon Home, according to the scheduled procedureInternational Organization for StandardizationDraft ISO14067 product carbon footprintinternational standard(referred to as ISO carbon footprint standard)FinalThe draft will still be determined in 2013, and the final version will be released in 2013.Experts generally believe that according to the latest version of this standardDraft for Comments, big countries will launch a new roundCarbon emission reductionplay a game。The standard aims to formulate more precise requirements for the quantification, notification and verification of carbon footprint of products, and provide a clear and consistent way of describing. It may soon become an internationally accepted standard for the assessment, monitoring, reporting and verification of carbon footprint.
Do not exclude the followingInternational procurementThe Chamber of Commerce incorporated it into its ownGlobal Supply Chainmanagement systemMedium.According to the carbon experts, the UK, Japan, the United States and other countries have established a variety of low-carbonCertification systemAnd labels, manydeveloped country% of enterprises also marked their productscarbon emissionOr energy-saving information to cater to consumers' environmental awareness.On the one hand, the ISO carbon footprint standard will form a new trade threshold, increasingCarbon certification, carbon labeling and other expenses, increase smallExport enterprisesCost, weakening itsIndustrial competitiveness；On the other hand, this standard will form a new technological threshold, accelerate the elimination of backward technologies, and most enterprises will have to pay high prices to buy from developed countriesadvanced technique。
Experts involved in standard formulation believe that,ChinaAlthough it is a major exporter in the world, most industries belong to the "two ends out" of raw materials and markets.Take refrigerators, washing machines, televisions and other household appliances for example, most of the carbon emissions of the products are out of the use stage, but if according to the ISO carbon footprint standard,Full life cycleAll the carbon emissions in China will be counted on China, which is unreasonable for big exporting countries including China.Once the ISO carbon footprint standard is passed, it may be incorporated into the WTO framework and become a rule that all member countries must abide by;As a member of WTO, China is bound to be subject to this standard.Once the ISO carbon footprint standard is officially released, according to WTO rules, the introduction of this standard will most likelyCarbon taxThe levy is included in the multilateral TBT system framework of WTO, and China will have to accept this passivelyMultilateral mechanisms。
To this end,Inspection and quarantineThe agency reminds relevant export enterprises toActive attentionThe development process of ISO carbon footprint standard, and learn more about relevant low-carbon certification systems and labels;We should strengthen research and development and improve the processtechnical method 。In this way, maximum maintenance can be achievedCorporate interests。

Increase awareness
When I was still talking about the discount of air tickets, reducing my personal "carbon footprint" had become the UK'sCatchwords。"Carbon footprint" refers to the impact of individual energy awareness and behavior onnatural environmentImpact, i.e. personal energyConsumptionAnd pollution emissions.Aircraft is the largest carbon emissionManufacturerTherefore, in Britain, public opinion advocates giving up unnecessary flight plans and using trains instead of short distance flights.
stayGermanFor the time being, there is no term corresponding to "carbon footprint".But Germanyenvironmental problemsI am afraid that the importance of the United Kingdom is more than that of the United Kingdom.In Germany, students often receive the education of "saving energy and reducing pollution";In the German media, the environment is also a constant focus topic;public occasionsIf the behavior is not environmentally friendly, it often attracts more glances than strange behavior;On the bus, global warming can also become a topic for strangers to chat up with each other.What's more, it is said that nowadays in Germany, whether the behavior is environmentally friendly has become the first standard to measure whether a person is educated.
Near the first World Low Carbon andEcological economyAnd the Technology ExpoNanchangOpening, at this conference with the theme of "energy conservation and emission reduction - green ecology"Low carbon ecological economy, reduce enterprisesCarbon emissions, taking "carbon footprint" as an enterprise to participate in environmental protectionsocial responsibilityOfNew coordinatesIt has become an important topic discussed by more than 1300 guests at home and abroad.
Carbon footprint
Carbon Footprint is also commonly referred to as "carbon consumption", which refers to a newly developed measure of energy consumption by institutions or individualscarbon dioxideEmission pairenvironmental effectIndicators of.As an important weapon against climate change, enterprises and individuals can determine their own "carbon footprint", understand "carbon emissions", and then control and restrict the behavior of individuals and enterprises to achieve the purpose of reducing carbon emissions.But the problem is that compared with the individual's constraints on their own behavior,organization structureHow can enterprises with complex and large institutions find a more systematic and effective way to achieve this goal?low-carbon economyThe answer is given.
low-carbon economy
Low carbon economy means toLow energy consumptionLow pollution and low emission basedeconomic model Its essence is to use energy efficiently and cleanenergy development. Realize the enterprise'sGreen development。This economic model not only means that enterprises should speed up the eliminationhigh energy-consumptionHigh pollution backwardnessthroughput, promote energy conservation and emission reductiontechnological innovationAt the same time, enterprises are required to set an example to guide employees and the public to reflect on what they are accustomed toconsumption patternAnd lifestyle are wasteful of energy and increase emissions of pollutionBad behaviorSo as to fully tap the huge potential of energy conservation and emission reduction in the industry and consumer life.
As the most intuitive new indicator of environmental protection, "carbon footprint" is the understanding and implementation of enterprisescircular economyThe proposed higher practice standard, and low-carbon economy is the specific implementation of this indicator.Only when enterprises and employees can consciously undertakeEnvironmental obligationsOnly by constraining and controlling can we truly realize our commitment to consumers, the country and the entire human living environment.
In the world, many well-known enterprises have taken "low carbon economy" and "carbon footprint" as measurementCorporate Social Responsibility (CRS), realizing the development direction of new leap of enterprises.Although these concepts have not been put forward for a long time in China, many enterprises already have ideas and concepts that are consistent with them.Express elevator“Green company"People" is a good example.In this regard, Zhu Kangzheng, president of Express Elevator, explained that "green company people" is the comprehensive embodiment of Express Elevator's environmental responsibility, which has two meanings.Externally, it means that enterprises provide consumers with "energy saving and environmental protection" products and efficient and convenient post maintenance;Internally, it aims to create green inside the enterpriseproduction environment So that "everyone has the concept of environmental protection and everyone participates in environmental protection".Through the joint efforts of enterprises and employees, create a green environment.
Undertake environmental protection responsibility
As enterprisesenvironmental awarenessWith the continuous improvement of, more and more enterprises have realized that, as the basic part for the normal operation of the big machine in modern society, enterprises have mastered various resources, especially natural resources and energy, so they have the obligation and responsibility to realizeeconomic performanceAt the same timesocial resultsBalance, through various ways to fulfill environmental obligations.“Carbon emission reduction”It is one step, not the only one.
As for this, Zhu Kang, president of the express elevator company, said:Environmental responsibilityThe implementation of is a comprehensive process.It needs to go from internal employees to customer consumption terminals, fromTechnology R&DTo product production, fromRaw material procurementreachSupplier managementAnd other links to implement this theme.Based on its own concept of "energy conservation and environmental protection" and the experience of other companies, the express elevator company formulates a comprehensive environmental protection strategy from the aspects of product energy conservation, safety, efficiency and relevanceIndustry managementStarting from three aspectspublic interest We will work together to better implement the goal of "corporate social people".
Green environmental protection is the first embodimentEnergy saving productsIn terms of research and development, the fast elevatorResidential elevatorWithPermanent magnet synchronizationnothinggearDrive and energyRegeneration technologyCan save about 50% of energy consumption, and prevent oil pollution from affecting the machine room andHoistwayEnvironmental pollution.In the SupEX seriesPassenger elevatorThe configuration scheme of small machine room and non machine room adopted in, which effectively saves the space of machine room and reduces the ownerShared areaAnd thus greatly reduces the energy consumption during elevator operation.
Safety and efficiency is another embodiment of the environmental responsibility of fast elevators, which not only ensures the safe operation of products, but also saves energy from the perspective of efficiency.In addition to adhering to the "All Safe" concept of everyone, every day, every construction site and use site, the enterprise also improves the use efficiency of products by increasing technology research and development efforts and elevator operation and maintenance safety education.For this reason, the enterprise has held variousSocial publicityAnd public welfare activities, such as "safe elevator" education, elevator operation and maintenanceSafety trainingSo as to drive more enterprises and individuals to join in the concept of safe and efficient environmental protection.
In addition, by sharing the concept of environmental protection, strengthen theEnvironmental standardsIt is another innovation of the fast elevator to the enterprise's environmental protection concept.In the view of fast elevators, industries are interconnected as a whole. Suppliers in various industries are indispensable partners of fast elevators. Fast elevators are willing to share their owncorporate culture、management philosophyAnd environmental protection experience, and in the continuous sharing and cooperation, get mutual recognition.fastSupplier managementThe department head said: "By optimizing the supply chainManagement procedures, combining environmental protection concept and efficientWorking methodsThe management and control process is extended to all key suppliers to assist them in the continuous improvement of products and services, so as to ensure the profitability of the enterprise itself and the industry while realizing the environmental responsibility of the enterprise. "
The proposal of a series of new environmental protection concepts, such as carbon footprint and low-carbon economy, is not only a proof of the increasingly serious environmental problems, but also reflects that mankind is making unremitting efforts to solve environmental problems."Everyone has a sense of responsibilitySense of missionOur enterprises should think carefully and take action for them. "Zhu Kangzheng, president of Express Elevator, said, "We have to treat everything with perseveranceEnergy saving and environmental protectionOnly by doing the "little things" can we stick to the "big things" of protecting the earth's ecology to the end, and there will be endlessLife continuity。”

Everyone has their own carbon footprint, which means everyone'sGreenhouse gas emissionsQuantity, incarbon dioxideIt is a standard calculation.This concept takes the image of "footprint" as a metaphor, which shows that everyone is increasing in the skygreenhouse gasesHas left its own traces.
A person's carbon footprint can be divided into the first carbon footprint and the second carbon footprint.The first carbon footprint is due to the use ofFossil energyBut directly dischargedcarbon dioxideFor example, a person who often travels by plane will have more first carbon footprints, because flying by plane will consume a lot of fuel and emit a lot of carbon dioxide.The second carbon footprint is the indirect emissions of carbon dioxide due to the use of various products, such as the consumption of an ordinary bottleBottled WaterBecause of its production andTransportation processResulting in the second carbon footprint.
It can be seen that the carbon footprint involves many factors.However, it is not difficult to calculate the carbon footprint. Many websites provide special“carbon footprint calculator ”As long as the relevant information is input, the carbon footprint of an activity can be calculated, and the total carbon footprint of the whole year can also be calculated.The larger the carbon footprint, the better theglobal warmingThe greater the responsibility.
The carbon footprint is proposed to make people realize the urgency of tackling climate change.For example, if 100 kilowatt hours of electricity is used, it is equivalent to about 78.5 kilograms of emissionscarbon dioxide, need to plant a tree to offset;If 100 liters of gasoline is consumed by self driving, about 270 kilograms of carbon dioxide will be emitted, which needs to be offset by planting three trees.

"China's carbon footprint open platform" system
In April 2023, the "China Carbon Footprint Open Platform" system will be released in Chengdu.For the first time in the world, China's carbon footprint open platform has realized the carbon footprint model's layer by layer retrospective display and analysis on PC and mobile phone terminals, so it is expected to correct the common misunderstanding that "the carbon footprint is too complex, and it is not clear to say it clearly", and promote the carbon footprint into a transparent, complete, clear and accurate credible era,We will help all walks of life develop in a low-carbon, green and high-quality way.[1]
In 2025, China's product carbon labeling certification system will be basically established
In November 2023, the National Development and Reform Commission issued an opinion, which will accelerate the improvement of China's carbon footprint management level of key products, promote the green and low-carbon transformation of related industries, and help achieve the goal of carbon neutrality. By 2025, the national product carbon labeling certification system will be basically established.[3]
The opinion points out that the country will accelerate the development of general national standards for the basis of carbon footprint accounting of products, and clarify the boundary, accounting methods, data quality requirements and traceability requirements of carbon footprint accounting of products;Encourage relevant industry associations, enterprises and scientific research units to collect and sort out relevant data resources of their own industries in accordance with laws and regulations, and release the background database of carbon footprint of products in the subdivided industry field on the basis of indicating the data source;Establish a unified and standardized product carbon identification certification system, and guide enterprises to save energy and reduce carbon by clearly marking the quantitative information of product carbon footprint;In addition, it will also enrich product carbon footprint application scenarios and promote international convergence and mutual recognition of carbon footprint.
By 2025, the country will introduce about 50 carbon footprint accounting rules and standards for key products, a batch of carbon footprint background databases for key industries will be initially established, and the national product carbon labeling certification system will be basically established.In 2030, about 200 carbon footprint accounting rules and standards for key products will be introduced at the national level, the national carbon labeling certification system for products will be fully established, and the product carbon footprint management system will provide a strong guarantee for the overall green transformation of economic and social development.[3]
On June 4, 2024, the Ministry of Ecology and Environment, the Ministry of Finance, the People's Bank of China and other 15 departments jointly issued the Implementation Plan on Establishing a Carbon Footprint Management System to accelerate the establishment of a carbon footprint management system, form a green low-carbon supply chain and production and lifestyle, promote the development of new quality productivity, and help achieve the goal of carbon peak and carbon neutrality.[7]The Plan points out that the carbon footprint management system will be initially established by 2027;By 2030, the carbon footprint management system will be more perfect and the application scenarios will be more abundant.[6]
