Generally, chicken and pork are considered more environmentally friendly than lamb or beef in terms of their carbon footprint. Here’s why:
- Feed Conversion Efficiency: Chicken and pork are more efficient at converting feed into meat. They require fewer resources, such as land, water, and feed, to produce the same amount of protein compared to cattle and sheep. This efficiency reduces the overall environmental impact.
- Greenhouse Gas Emissions: Cattle, especially beef cattle, produce significant methane emissions during digestion. Methane is a potent greenhouse gas that contributes to climate change. Pigs and chickens produce fewer methane emissions per unit of meat produced.
- Land Use: Cattle farming typically requires more land compared to poultry and pork production. Land conversion for agriculture can lead to deforestation and habitat loss, which has a negative impact on biodiversity.
- Water Use: Beef production generally consumes more water per unit of meat produced compared to chicken and pork. Water scarcity is a growing concern in many regions, making efficient water use an important environmental factor.
- Feed Composition: Cattle and sheep are often raised on forage-based diets, which can require more land and resources than the grain-based diets commonly used for poultry and swine.
However, it’s important to note that the environmental impact of meat production can vary depending on factors like farming practices, location, and feed sources. Sustainable and regenerative farming methods can reduce the environmental footprint of all types of meat.

Ultimately, if you are concerned about the environmental impact of your meat consumption, choosing chicken or pork over lamb or beef can generally be a more eco-friendly choice. However, the most significant impact you can make is by reducing overall meat consumption and choosing sustainably sourced meat when you do eat it. Plant-based diets also have a lower environmental footprint compared to meat-based diets.
