In recent years, the impact of product production and consumption on the environment has been paid more and more attention. As an important indicator to measure the environmental impact of products, "product carbon footprint" has become an element that cannot be ignored in product life cycle management. The "Product Carbon Footprint" (PCF) refers to the total amount of greenhouse gases released at various stages of a product's life cycle, such as production, manufacturing, transportation, use, and disposal. By reducing the carbon footprint of products, companies can reduce energy consumption, reduce raw material waste, and increase the recycling rate of material resources, thereby reducing operating costs and risks, and improving the environmental performance and competitiveness of products.
In response to this demand, Duneng AIoT Energy Carbon Digital Intelligence Platform has newly launched a product carbon footprint management module. It covers product modeling, carbon emission accounting, statistical analysis, data management and other functions, integrates the international carbon footprint accounting standards ISO14067 and PAS 2050, and integrates a large number of carbon emission factors to participate in the accurate accounting and multi-dimensional analysis of carbon footprint data at each stage of the product life cycle. With the help of the Duneng AIoT carbon digital intelligent platform, enterprises can easily realize the digital management of the whole process of product carbon footprint, fully explore the carbon reduction potential of the production process, reasonably formulate emission reduction measures, scientifically reduce carbon emissions, accelerate the realization of their own carbon neutrality goals, and accelerate the completion of intelligent and green transformation.
Duneng's carbon footprint management functions and product advantages
▎ It can support custom modeling of carbon footprint and accurately calculate the carbon emission data of the whole life cycle of the product
Accounting for the carbon footprint is the first condition and the most critical step in reducing the carbon footprint of a product. Considering that the carbon emission data collection of products from raw material acquisition, manufacturing, distribution and transportation, product use to product disposal is complex and time-consuming, based on Life Cycle Assessment (LCA), a custom modeling method for the whole life process of products is proposed to provide upstream supply chain enterprises and downstream users with real-world data filling function, unified management of carbon emission data, and reliable traceability of product carbon footprint.
■ Function 1: Product modeling
The platform has built-in 24 standard industries and accounting templates of the National Development and Reform Commission, which supports the entry of basic information of accounting products, industries, accounting templates, accounting boundaries and other parameters, and users can choose Bill of Material (BOM), process flow charts, data forms and other ways for custom modeling. At the same time, the product model supports editing, publishing, copying and other operations, and after users publish the product model with one click, they can fill in the carbon footprint of their whole life cycle.

■ Function 2: Carbon footprint reporting
The platform covers mainstream carbon emission factors at home and abroad, traces the carbon emission data in the entire life cycle of the product, and supports multiple ways to enter carbon footprint-related activity data to meet the reporting needs of different enterprises and scenarios. Users can obtain carbon emission related vouchers from sub-suppliers online and upload them to the system, thereby improving the efficiency of enterprise accounting and reporting, realizing data trace storage, and replacing the cumbersome procedures of offline communication and reporting.

▎Du can provide intelligent visual display and analysis of data to accelerate the completion of carbon footprint green certification for enterprises
In order to effectively solve the problems of inaccurate carbon footprint accounting, high accounting cost, and lack of authority of accounting results, Duneng provides a simple and efficient one-stop carbon footprint analysis function, enterprises can preview data online and export carbon footprint accounting report with one click, deeply understand the carbon emissions of the product production chain, and expand product richness with low-carbon concepts to enhance market competitiveness. In addition, Duneng has established cooperative relations with institutions approved by the Ministry of Ecology and Environment, and successfully introduced institutions to settle in the platform, so that enterprises can enjoy convenient and fast online product carbon footprint certification services, responding to compliance needs in scenarios such as overseas trade and export of goods.
■ Function 3: Carbon footprint overview
It can integrate a variety of domestic and foreign carbon emission parameter recommended values and emission factor libraries to participate in the calculation of product carbon footprint, and support data visualization. By aggregating and displaying the accounting results, enterprises can fill in the gaps in the carbon footprint data that has been filled in to meet the needs of diversified chart analysis. In addition, the platform also supports accurate measurement of carbon emissions in the manufacturing stage of products, so that users can accurately locate the process nodes with the largest emissions, so as to formulate reasonable and economical emission reduction plans based on actual production conditions to assist enterprises in optimizing emission reduction decisions.

■ Function 4: Carbon footprint report
After the user completes the carbon footprint accounting, the product carbon footprint report can be generated with one click. Carbon footprint report is an effective means for enterprises to communicate with the outside world, through carbon footprint disclosure, can directly reflect the carbon emissions in product production and operation, and help enterprises reasonably respond to the demand for green raw materials downstream of domestic and foreign supply chains. In addition, enterprises can also carry out online product carbon footprint certification, including inquiry and quotation, research and verification, certificate issuance and other whole processes. The carbon footprint certificate is not only a strong endorsement of the company's carbon management and control capabilities, but also provides an effective guarantee for the enterprise to enhance its green competitiveness.

■ Industrial park
As the concept of energy conservation and emission reduction gradually takes root in the hearts of the people, more and more enterprises have begun to pay attention to the carbon footprint inventory of industrial products, especially the demand for high-carbon emission industrial parks is stronger, but there is a lack of an executable carbon emission accounting and carbon footprint tracking standard system. For the carbon emission scenario of a large industrial park, the Duneng carbon footprint management platform can timely track and collect the carbon footprint data of the whole life cycle of the park's products, accurately locate the carbon emissions of each production link, and promote enterprises to reduce carbon emissions through carbon capture, utilization and storage (CCUS) and certified voluntary emission reduction (China CCER) and other carbon trading measures to achieve energy conservation and emission reduction, increase the potential carbon trading quota, and realize the refined and intelligent management of the overall carbon emission situation of the park.
■ Vehicle enterprises
With the implementation of policies related to the carbon footprint of products at home and abroad, the "dual carbon" goal has become a global consensus, and global vehicle enterprises are paying more and more attention to the carbon footprint of automobiles. At present, China has not yet issued standards for carbon emission accounting in the automotive industry, and the accounting process is uncertain, and it is difficult to ensure the accuracy and standardization of accounting. In order to achieve the low-carbon goal and accelerate the low-carbon transformation of the automotive industry chain, the Doneng carbon footprint management platform has established a complete carbon footprint accounting management system for a vehicle factory, presenting the carbon emission data of each stage of automobile production and manufacturing in multiple dimensions, realizing carbon emission reduction throughout the life cycle from parts acquisition, vehicle manufacturing, to after-sales, etc., so that enterprises can comprehensively and clearly understand the carbon footprint information of their products, realize the transparency of carbon footprint information of automotive products, and guide users to low-carbon consumption.
■ Sewage treatment
However, many sewage plants do not have complete statistics on oxidative carbon emissions from biological treatment at each stage when calculating carbon emissions, and lack of greenhouse gas emissions data generated by upstream and downstream water quality, resulting in large energy consumption and inaccurate accounting. Based on this, Duneng constructed a sewage treatment carbon footprint accounting analysis model for a large-scale sewage treatment plant, covering the main discharge links such as sewage transportation and treatment and sludge transportation and disposal, and monitored the carbon footprint data of the whole process of sewage treatment in multiple dimensions. For complex and diverse sewage treatment biochemical processes, it can optimize the energy consumption data of bioprocesses such as aeration systems, reduce the carbon footprint of sewage treatment, standardize the carbon footprint accounting method of enterprises, improve the transparency of the impact of carbon emissions on the environment, and promote the carbon neutrality of sewage plants.
The significance and development of Duneng's carbon footprint management
Baidu Intelligent Cloud can focus on the field of dual carbon, establish a carbon footprint tracking system for the whole life process of products, and create a complete set of enterprise carbon inventory solutions from the product dimension to help enterprises efficiently manage products. For production-oriented enterprises, quantitative analysis of carbon footprint data is conducive to reducing supply chain carbon emissions and reducing production costs. For export manufacturing enterprises, carrying out product carbon footprint is the only way to certify green products and zero-carbon factories, which provides a practical basis for them to reasonably respond to international carbon tariff barriers. In addition, carbon footprint labels can also be used as a differentiated product strategy for companies, motivating business partners to make better decisions and advocating consumers to actively implement low-carbon environmental protection measures.
Under the dual carbon goals, low-carbon development has become the consensus of the whole society. As a new scale for the green development of enterprises, carbon footprint can fully display carbon emissions in the production process of products, improve the carbon emission management level from product design to production process through accurate accounting and multi-dimensional analysis of carbon footprint data of different life cycles of products, and promote enterprises to achieve energy conservation and emission reduction faster and better. In the future, Duneng will continue to explore the strategic opportunities of product carbon footprint in "carbon peaking and carbon neutrality", promote the digital and intelligent low-carbon transformation of enterprises through information sharing and resource integration, and continue to empower the green development of all walks of life.
