The article explores how policies to reduce greenhouse gas emissions impact the livestock industry. By using a detailed model, the researchers studied how different policies affect livestock production, competitiveness, and food consumption globally. They found that imposing a carbon tax on agriculture can decrease food consumption, especially in developing countries. However, providing subsidies to farmers can help offset these effects. Additionally, offering subsidies for forest carbon sequestration can help control emissions but may also limit agricultural growth in certain regions, potentially impacting food security and agricultural development in developing countries.
