Activity data collection for Tier 2 estimates of livestock emissions in China

  1. 1. Prof. Dong Hongmin Deputy Director General & Ph.D. Institute of Environment and Sustainable Development in Agriculture,CAAS Activity Data Collection for Tier 2 Estimates- CHINA
  2. 2. 1. Country context: livestock emissions, policy objectives 2. Structure of inventory and reporting 3. Activity data needs for Tier II accounting 4. Challenges and current g practices 5. Examples of decisions using activity data Outline
  3. 3. GHG Emissions in China 74-78% 7-12% 8-17% 1-4% 5-10%
  4. 4. 2012 GHG Emission in China  China GHG emission (excluding LUCF) in 2012 was 11896 Mt CO2e  CO2 accounted for the largest portion of emission, which is 83.2%, followed by CH4 (9.9%), N2O (5.4%)  Energy sector, which accounted for 78.5%, is the largest contributor  Agriculture contributed around 7.9% of national total 主要温室气体排放占比
  5. 5. 2012 GHG Emission from Agriculture Sector  China agriculture GHG emission in 2012 was 938 MtCO2e  Cropland accounted for the largest portion, 40.3%  Livestock sector contribute 39.8%. Enteric 24.1% Manure 15.7% Rice cultivation 18.9% Cropland 40.3% Field burning 1.1%
  6. 6. 2012 GHG Emission from Livestock Sector  China livestock GHG emission in 2012 was 373 Mt CO2e  Enteric contributed to 60.5% of livestock emission  Manure CH4 and N2O are responsible for 18.8% and 20.7%, respectively
  7. 7. 13th five-year plan for economic and social development  China Responded to Global climate change While working hard to both adapt to and slow down climate change, we will take active steps to control carbon emissions, fulfill our commitments for emission reduction  Greenhouse gas emissions control  Effectively control carbon emissions in key industries  Control the emissions of Non-CO2 greenhouse gases.  Estabilishment of a national carbon trading scheme  Implement MRV system and quota management for major emitters  Improve statistical systems  During the 13th five-year period, carbon dioxide emissions per unit GDP will decrease by 18% as a binding indicator
  8. 8. China Nationally Determined Contributions  China NDC are as follows  To achieve the peaking of carbon dioxide emissions around 2030 and making best efforts to peak early  To lower carbon dioxide emissions per unit of GDP by 60% to 65% from the 2005 level  Agricultural related content in NDC  To promote the low-carbon development in agriculture, making efforts to achieve zero growth of fertilizer and pesticide utilization by 2020  To control methane emissions from rice fields and nitrous oxide emissions from farmland  To construct a recycle agriculture system, promote comprehensive utilization of crop wastes and animal manure
  9. 9. Structure of Inventory and Reporting
  10. 10. The Scope of Livestock GHG Inventory in 2012  Methodologies  《1996 IPCC Guideline》  《IPCC GPG》  The Scope of 2012  CH4 from Enteric Fermentation  CH4 from Manure Management  N2O from Manure Management  Not reported in livestock sector :  N2O emission from manure after land application  N2O emission from grazing animals
  11. 11. Sources of GHG in Livestock Sector  Enteric CH4 Including 12 categories of animals: Cattle(Dairy cow、Beef cattle、Buffalo、 yak、Other cattle)、Sheep(Goats、Sheep)、Horses、Asses、Mules、 Camels 、Swine  Manure CH4 and N2O  14 categories of animals:12 categories in the enteric sector + Poultry + Rabbit  13 types of manure management systems Pasture/Range/Paddock , Daily spread , Solid storage , Dry lot , Liquid/Slurry, Uncovered anaerobic lagoon , Pit storage below animal confinements , Anaerobic digester , Burned for fuel, Deep bedding, Composting, Aerobic treatment and Others)
