What is a carbon footprint? Carbon footprint is a term that is often mentioned in today's environmental issues. But what exactly is a carbon footprint? In this article, we will introduce the concept of carbon footprint in a concise way, take you through the main factors and methods of carbon footprint calculation, and explore ways to reduce carbon footprint. Finally, we will discuss the importance and impact of carbon footprint calculation methods.
What is a carbon footprint?
What is a carbon footprint? It refers to the total amount of greenhouse gases emitted by an individual, organization or product during the production and consumption process, usually measured in carbon dioxide equivalent. These greenhouse gases include carbon dioxide, methane, fluorine, etc., which affect the earth's temperature and climate change.
Carbon management capabilities
In terms of carbon management capabilities, ISO14067 is an indicative standard that can be used as a current inventory of carbon footprints. This system is based on consumer products, and footprint calculations extend to the supply chain, so the scope of ISO14067 is often applied for by product.
Understand what carbon footprint is from the basics of how it is calculated
After understanding what carbon footprint is, the next thing to understand is the basis of how to calculate carbon footprint. For consumer products or products produced by an organization, the carbon footprint calculation is based on activities that produce greenhouse gases, including energy use, transportation, food production and consumption, etc. The greenhouse gases released by these activities are converted into carbon emissions and expressed in terms of carbon emission equivalents.
Taking a factory product as an example, the carbon footprint calculation method is a life cycle concept. For example, every link from raw material acquisition to waste disposal, that is, from raw materials obtained or produced by natural resources to end-of-life disposal, the compilation and quantification of all inputs and production is the basis for us to calculate the carbon footprint. At present, ISO14067 is a very complete system architecture for quantifying and reporting product carbon footprint (CFP).
It is currently also followed by many carbon footprint labels. An organization must first obtain relevant certification, such as ISO14067, before it can obtain a carbon footprint seal and mark it on its products.

Main factors and methods of carbon footprint calculation
The main factors in calculating carbon footprint include energy consumption, transportation methods, eating habits, and item consumption. Methods include using carbon footprint calculation tools, analyzing energy use, monitoring transportation patterns, evaluating dietary choices, etc.
Simply put, carbon footprint = the total greenhouse gas emissions generated by a product or service throughout its life cycle, expressed in CO2 equivalents (CNS 14067 3.1.1.1)
First, we need to establish: Purpose and scope definition: confirm that the purpose of performing carbon footprint calculation is to seek product carbon reduction opportunities, green the supply chain and form a Green Partner with the supply chain, or continuously improve carbon reduction, etc. This is used to determine which unit processes should be included in the product carbon footprint assessment.
Next is the process flow chart: Construct a product life cycle process map based on the scope definition, which may include all raw materials, energy, waste, and other input-output items from raw materials to waste treatment.次はプロセス フロー チャートです。スコープ定義に基づいて、製品ライフ サイクル プロセス マップを作成します。これには、原材料から廃棄物処理までのすべての原材料、エネルギー、廃棄物、その他の入出力項目が含まれる場合があります。
Next is data collection: data collection is carried out based on the input of various raw materials, energy and resources involved in the product manufacturing process, as well as the output of various wastes (air, water, and garbage).
Final carbon footprint calculation: Use the project emission factor (provided by the supply chain) × activity data (all usage data in the production process of the target product) related to all substances, energy, and emissions in the product life cycle
Ways to reduce your carbon footprint
To reduce carbon footprint, we can save energy, improve transportation methods, adopt a low-carbon diet, and reduce consumption of goods. This includes using energy-efficient appliances, taking public transportation, choosing local and seasonal ingredients, and purchasing environmentally friendly products.
Importance and impact of carbon footprint calculation
Calculating carbon footprint can help individuals and organizations understand their carbon emissions and become aware of their contribution to climate change. By reducing carbon footprint, we can slow down the pace of climate change, protect the earth's environment and ensure sustainable development in the future.
In summary, carbon footprint calculation is an important environmental management tool that helps us realize the impact of our behavior on the earth's environment and provides ways and methods to reduce carbon emissions. By calculating our carbon footprint, we can work together to create a cleaner, healthier planet.
After the final ISO14067 verification, there will be a complete carbon footprint report, including the scope, methods, calculation data and evaluation results. After verification by the verification unit, an ISO 14067:2018 verification statement will be issued. After obtaining the carbon footprint certification of the verification statement from a third-party impartial organization, it can be used as the basis for applying for a "carbon label" and marking the product's carbon emissions on the product. The data from this inventory can also be used as evidence to obtain a "carbon reduction label" in the future.
