A recent study has found that grass-fed beef does not significantly reduce carbon emissions compared to beef produced in industrial feedlots. Researchers discovered that even in ideal conditions, grass-fed cattle still produce similar levels of emissions that contribute to climate change. This finding challenges the idea that grass-fed beef is a more eco-friendly choice. Despite this, some experts argue that grass-fed beef offers benefits like better animal welfare and improved local environmental conditions. The study encourages consumers to think carefully about the environmental impact of their food choices, especially as global beef demand continues to rise. Researchers also expressed concern that beef production in areas like South America often leads to deforestation, which worsens carbon emissions.

The study showed that grass-fed cattle take longer to grow and require more resources to reach market weight, making the process less efficient. Since grass-fed cattle grow slower and are smaller than feedlot cattle, more animals are needed to produce the same amount of meat. Researchers used numerical models to study emissions throughout the beef production process. They measured methane output, carbon dioxide emissions, and total meat production. While some experts believe grass-fed cattle can improve soil carbon storage, the study found that this benefit is not enough to offset the higher emissions. Experts continue to debate how to balance reducing emissions with promoting sustainable farming practices.
