Comparing the Life Cycle Greenhouse Gas Emissions of Dairy and Pork Systems Across Countries Using Land-Use Carbon Opportunity Costs

The research evaluates the lifecycle greenhouse gas (GHG) costs of dairy and pork production across multiple countries, utilizing a carbon opportunity cost method for land use. It finds that emissions variability is driven by feeding conversion efficiency, manure management, and temperature, while noting that developed agricultural countries show similar emission levels, suggesting a need for innovation over the adoption of existing methods to achieve further reductions.

• The use of carbon opportunity costs to account for land use increases the total GHG costs for both dairy and pork production and decreases the variability of these costs between different countries compared to other life cycle assessment (LCA) methods.
• Variations in emissions between countries are primarily driven by country temperatures, manure management methods, and feeding conversion efficiency.
• In dairy production, a greater reliance on grazing generally increases GHG costs for most countries, though New Zealand is an exception due to its highly intensive grazing practices.
• Denmark is categorized among the lowest emitting countries, though its emission levels are similar to several other nations.
• Because emissions are similar across developed agricultural countries, further significant reductions will require new innovations rather than the adoption of existing practices from other developed nations.
