Question 1

1. Which future trend is expected for the carbon intensity of agricultural production. What are the reasons?

Answer 1

→ Carbon intensity of agricultural production is declining

reasons:
- Global agricultural emissions are set to increase but the carbon intensity of agricultural production is expected to decrease over the next decade
- growth of agricultural production is expected to exceed the growth in direct GHG emissions from agriculture
- driven by yield improvements, declining share of ruminant production

Question 2

2. Slide 48-49: What are the main differences concerning the global emissions and distribution among the main categories of emission between the supply chains for pig meat, milk and beef milk

Answer 2

beef Meat: 43 % enteric CH4; 18 % applied & deposited manure N2O; 15% Pasture expansion CO2, 10 % Feed CO2

cattle Milk: 50 % enteric CH4; 17 % applied & deposited manure N2O; 10% feed CO2, 5 % Manure Management N2O

pig meat: 30% feed CH4, 20 % Manure management CH4; LUC soybean CO2
