反刍动物碳排放数据集

反刍动物碳排放数据集基于国际先进的温室气体检测设备GreenFeed系统，在北京市典型牧场实地采集泌乳期奶牛的甲烷、二氧化碳等温室气体排放数据，经过系统化质量控制与标准化处理，具备高度的可溯源性和科学性。该数据集主要用于解决当前奶牛温室气体排放因子缺失、碳排核算不精准、碳减排路径评估困难等行业共性难题。通过提供高分辨率、实测级别的排放数据，支撑以下关键场景应用： （1）为碳足迹核算与生命周期评价（LCA）提供关键排放因子，提升我国奶业碳排放量化水平；（2）服务于国家及地方温室气体清单编制与碳核查机制，弥补基础数据缺口；（3）为减排技术评估、养殖模式优化与精细化管理提供决策依据；（4）支撑科研人员构建和验证动物碳排放预测模型与排放规律识别模型；（5）为企业开展绿色低碳产品认证、碳标签标识提供依据；（6）向公众和媒体展示奶业低碳转型进展，增强社会对畜牧业“双碳”工作的认知与信心。 本数据集已在实际研究与政策制定中广泛应用，具有高度推广价值和持续更新潜力，是我国推进奶牛养殖碳排放数据标准化和数字化的重要基础资源。The ruminant carbon emission dataset is developed using the internationally advanced GreenFeed greenhouse gas detection system. It collects real-world greenhouse gas emission data including methane, carbon dioxide and other relevant gases from lactating dairy cows at typical pastures in Beijing. After undergoing systematic quality control and standardized processing, the dataset boasts high traceability and scientific rigor. This dataset primarily addresses the common industry challenges currently faced, such as the shortage of greenhouse gas emission factors for dairy cows, inaccurate carbon emission accounting, and difficulties in evaluating carbon emission reduction pathways. By providing high-resolution, field-measured emission data, it supports the following key application scenarios: (1) Providing key emission factors for carbon footprint accounting and Life Cycle Assessment (LCA), thereby improving the carbon emission quantification capacity of China's dairy industry; (2) Supporting the compilation of national and local greenhouse gas inventories and carbon verification mechanisms, and filling the gaps in basic data; (3) Providing decision-making support for emission reduction technology evaluation, breeding mode optimization and refined management; (4) Enabling researchers to construct and validate animal carbon emission prediction models and emission pattern recognition models; (5) Providing a reliable basis for enterprises to carry out green and low-carbon product certification and carbon label identification; (6) Demonstrating the progress of low-carbon transformation in the dairy industry to the public and media, and enhancing public awareness and confidence in the "dual carbon" work of the animal husbandry sector. This dataset has been widely applied in practical research and policy-making, possesses high promotion value and continuous update potential, and serves as an important foundational resource for promoting the standardization and digitalization of carbon emission data from dairy farming in China.
