Carbon emission statistics and accounting are an important foundation for achieving carbon peak and carbon neutrality, and accelerating the establishment of carbon footprint standards and product carbon standards for important products. The identification and certification system plays an important role in promoting the green and low-carbon transformation of the industry. This document is based on the product carbon footprint quantification requirements specified in GB/T 24067 "Requirements and Guidelines for Quantification of Carbon Footprint of Temperature Gas Products". The national standard for carbon footprint of agricultural products is formulated for the first time, aiming to provide specific carbon footprint of livestock products and some livestock products. The quantitative methods and requirements are used to provide technical guidance for ensuring food security and the supply of important agricultural products, and supporting agricultural and rural emission reduction and carbon sequestration. This document establishes the carbon footprint of livestock products by providing clear and consistent methods and requirements for quantifying the carbon footprint of livestock products using a life cycle assessment approach. The principles and objectives of product carbon footprint accounting are defined, and the accounting scope, steps, data, methods and reporting requirements are specified. Governments, industries, businesses and other stakeholders benefit from it, including.

--- Clarify the requirements for quantifying the carbon footprint of livestock product production;

--- Unify the methods for quantifying the carbon footprint of livestock production;

--- Promote the assessment of the carbon footprint of livestock products throughout their life cycle;

---Identify key emission links in the entire livestock production process and tap into emission reduction potential;

--- Improve the credibility, consistency and transparency of livestock carbon footprint quantification and reporting;

--- Promote the development and implementation of greenhouse gas management strategies and plans in livestock product supply chains. To facilitate domestic and international communication, according to the relevant requirements of the United Nations Intergovernmental Panel on Climate Change (IPCC), this series of documents The quantity value is expressed in the form of "International Unit of Quantity of Substance (Element)" or "International Unit of Quantity of Substance (Element)", such as tC for tons of carbon, tCO2 stands for tons of carbon dioxide, tCO2e stands for tons of carbon dioxide equivalent, tCH4 stands for tons of methane, and Nm2 stands for cubic meters under standard conditions.

1 Scope

GB/T 44903-2024 sets the Chinese method for quantifying the carbon footprint of livestock products. It is the product-level counterpart to the enterprise-level livestock accounting standard, and it is the one that reaches export markets, because a buyer asking a Chinese supplier for the footprint of a consignment of pork, beef, milk or eggs is asking for a product figure calculated to a defined method. Livestock footprints are dominated by two terms that are hard to allocate: the methane from enteric fermentation and manure, and the emissions embodied in the feed, which for Chinese production often includes imported soy with a land use change history. The standard sets the system boundary and the functional unit, the cut-off rules, the treatment of the feed supply chain and of land use change, the allocation between co-products such as milk and meat or meat and hide, the calculation of the emissions from each source, the data quality requirements, the uncertainty, and the reporting and the verification of the result. It takes effect on 1 May 2025.

2.Primary products include meat, eggs, milk, wool, down, etc.

3.2 The sum of greenhouse gas emissions and removals from the product system, expressed in carbon dioxide equivalent, based on climate change as a single environmental Conduct life cycle assessment based on impact types. [Source: GB/T 24067-2024, 3.1.1]

3.3 The sum of greenhouse gas emissions and removals in one or more selected stages or processes within the life cycle of a product system, expressed as CO2. It is expressed in carbon equivalent. [Source: GB/T 24067-2024, 3.1.2]

3.4 The sum of greenhouse gas emissions and removals from livestock production systems, expressed as carbon dioxide equivalent, based on climate change as a single factor. Conduct life cycle assessment based on environmental impact types.
