Countries are required to account for greenhouse gas (GHG) emissions and their mitigation under the UNFCCC’s Paris Agreement, yet most countries are still developing their systems for the measurement, reporting and verification (MRV) of emissions in agriculture. Guidance from the IPCC exists to estimate impacts, yet implementation of MRV also requires tailoring to country needs and conditions. In the livestock sector, accurate, comparable, consistent, complete and transparent MRV systems that can capture changes in emissions and sequestration from a range of practices and agroecological conditions are essential to guide the transformation to a low emissions future. Many countries with livestock emissions are seeking advanced GHG accounting to better reflect national circumstances and track mitigation due to productivity changes. To help countries improve accounting, CCAFS and experts across the globe are working together with countries to identify cost-effective technically sound MRV and the guidance, tools, and platforms that support them. As part of its national accounting, China is now seeking to improve their MRV of emissions from livestock. This project supports that effort. The purpose of this study is to develop methods and systems for Tier II MRV of livestock emissions at provincial level (Hebei Province) in China. - The objectives of this project are: (1) Produce practical guidance; (2) Build capacity for Tier II MRV among province-level authorities; (3) Develop methods and that can be used to support Tier II MRV elsewhere.

With the rapid human population growth and economic development, demand for animal products continues to increase and livestock production rapidly expands. Greenhouse gases (GHG) emission from livestock research 7.52 billion tons CO2-eq per year, accounting for 50% of agricultural emissions and 18% of global anthropogenic GHG emissions (FAO, 2014), making it become an important source of GHG emissions. The Chinese livestock production emits 373 GHG of million tons CO2-eq. Methane (CH4) emitted from enteric fermentation is 10.74 million tons (equivalent to 225.6 million tons CO2-eq), accounting for 60.7% of total livestock GHG emissions. CH4 emitted from manure management is 3.33 million tons (equivalent to 69.9 million tons CO2-eq), accounting for 18.9% of total livestock GHG emissions. Nitrous oxide (N2O) emitted from manure management is 0.25 million tons (equivalent to 77.2 million tons CO2-eq), accounted for 20.4% of the total livestock GHG emissions (MEE, 2018). The enteric fermentation and manure management contribute 40% to agricultural GHG emissions. Expansion of livestock production results in high demand of feedstuffs, bringing greater pressure on natural resources. It is of particular concern that the livestock sector has already been a major user of natural resources. For example, approximately 35% of total cropland and 20% of green water have been used for animal feed production (Opio et al., 2013). Feed-related emissions represent about half of total emissions from livestock supply chains (Gerber et al., 2013). Therefore, it is very important to evaluate GHG emissions from the whole life cycle of livestock production. Besides improved manure utilization and water usage efficiency, management of carbon emissions and carbon footprint is highlighted as an important research topic. This project is expected to identify and execute appropriate interventions for reducing carbon footprint and economic cost of dairy production.
