A recent study found that grass-fed beef does not significantly lower carbon emissions compared to beef from industrial feedlots. Researchers discovered that even under ideal conditions, grass-fed cattle still produce similar levels of harmful emissions. This challenges the belief that grass-fed beef is a better choice for the environment. However, some experts point out that grass-fed beef may still offer benefits like improved animal welfare and better local environmental conditions. The study encourages consumers to carefully consider the environmental impact of their food choices, especially as global beef demand continues to increase. The study also revealed that grass-fed cattle take longer to reach market weight and require more resources, making the process less efficient. Because grass-fed cattle grow slower and are smaller than feedlot cattle, more animals are needed to produce the same amount of meat. Researchers used models to measure methane output, carbon dioxide emissions, and total meat production. While some experts believe grass-fed cattle may improve soil carbon storage, the study found this benefit is not enough to outweigh the higher emissions.
