The production of red meat, such as beef and lamb, has a significantly larger carbon footprint than white meat, such as chicken and pork. Greenhouse gas emissions from red meat are higher due to the large amounts of methane released during the animals' digestive processes and their feed production. In contrast, pork and chicken production show lower carbon dioxide equivalents, and switching from red meat to these alternatives can significantly reduce an individual's carbon footprint.

What You'll Learn
Pork and chicken produce fewer emissions than red meat
Red meat, especially beef and lamb, has a much higher carbon footprint than chicken, pork, or plant-based alternatives. Pork and chicken production show lower carbon dioxide equivalents, at 7-12 kg CO2-eq and 6-9.87 kg CO2-eq per kilogram of meat, respectively. This is less than a third of the emissions from beef, which produces 36-60 kg CO2-eq per kilogram.
The large differences in the carbon footprint of different foods are due to variations in production methods and the number of animals being farmed. For example, 81% of chicken and 61% of pork are produced intensively in industrial farm settings, which tend to have lower emissions than other farming methods. In contrast, beef farming methods vary significantly depending on geography and local conditions such as soil fertility, terrain, and temperature.
The high emissions from beef production are also due to the large number of cows being farmed, as well as the fact that cows are ruminants, which means they produce methane gas through their digestive processes and belching. Methane is a potent greenhouse gas that contributes significantly to global warming. On the other hand, pigs are not ruminants, so they produce much less methane.
By switching from beef to chicken or pork, individuals can significantly reduce their dietary carbon footprint. This is because chicken and pork have lower emissions per kilogram of meat produced, and they are also often produced using less carbon-intensive methods outside of the US. Additionally, eating less meat overall, especially red meat, is another effective way to reduce the climate impact of one's diet.
In conclusion, pork and chicken produce fewer emissions than red meat, particularly beef and lamb. This is due to differences in production methods, the number of animals being farmed, and the fact that cows are ruminants that produce methane gas. By choosing lower-impact meats and reducing overall meat consumption, individuals can play a role in mitigating climate change.

Pork has the third-highest environmental impact among meats
Pork's environmental impact is largely due to intensive farming operations. Unlike cows and sheep, pigs are not ruminants, so they produce less methane. However, intensive farming practices, such as industrial-farm settings, contribute to pork's relatively high carbon footprint. According to the Environmental Working Group (EWG), pork consumption in the United States was 52 pounds per person in 2022, highlighting the significant contribution of pork production to the country's carbon emissions.
The impact of pork production on the environment is not limited to greenhouse gas emissions. Pork farming, like other forms of livestock farming, requires significant land use, contributing to the conversion of natural habitats into agricultural land. This can lead to biodiversity loss and ecosystem disruption. Additionally, the production of feed for pigs accounts for a substantial portion of the environmental impact, as feed production is a major driver of emissions and land use in the livestock industry.
To reduce the environmental impact of their dietary choices, individuals can opt for lower-impact meats, such as chicken, or plant-based alternatives. Reducing overall meat consumption is also an effective strategy, as meat and dairy production contribute significantly to global greenhouse gas emissions. By choosing more sustainable options and reducing meat intake, individuals can play a role in mitigating the environmental impact of the food industry.

Chicken has a lower carbon footprint than red meat
Beef production remains the biggest source of greenhouse gas emissions in the food industry, with 25% of emissions attributed to this alone. In contrast, chicken and pork are produced in industrial farm settings, which tend to be very similar worldwide, resulting in a smaller range of emissions.
The Environmental Working Group (EWG) estimates that lamb and beef from dairy herds produce five times more emissions than chicken for the same amount of protein. Even when excluding methane, the average footprint of beef is nearly four times that of chicken.
Swapping red meat for chicken can significantly reduce an individual's carbon footprint. For example, Americans' consumption of beef and pork has decreased, while their consumption of chicken has increased, resulting in a lower foodprint. Choosing chicken over beef may reduce the climate impact of your food by half.
In conclusion, chicken has a lower carbon footprint than red meat due to the high methane emissions associated with ruminant meat production. Lowering meat consumption or switching to chicken can be an effective way for individuals to reduce their dietary carbon footprint.

Greenhouse gas emissions from pig and chicken supply chains
Greenhouse gas emissions from the global food industry are predominantly linked to breeding and rearing cows, pigs, and other livestock, as well as producing feed. In this context, it is important to note that meat and dairy account for around 14.5% of global greenhouse gas emissions, according to the UN's Food and Agricultural Organization (FAO).
Pork and chicken production generally show lower carbon dioxide equivalents than red meat. For instance, while pork production ranges from 7-12 kg CO2-eq per kilogram of meat, beef production is responsible for 9 kg CO2-eq per kilogram of meat. Similarly, chicken production emits 6.0 kg CO2-eq per kilogram of meat, which is significantly lower than red meat.
However, it is worth noting that the environmental impact of pork and chicken supply chains can be significant due to intensive farming operations. For instance, 61% of pork and 81% of chicken are produced intensively in industrial farm settings. These intensive systems contribute to greenhouse gas emissions through feed production, animal digestive processes, and manure storage.
To reduce the climate impact of their diets, individuals can choose meats with lower environmental impacts, such as chicken, eggs, or pork. Additionally, reducing overall meat consumption, especially red meat and dairy, is recommended to minimize dietary greenhouse gas emissions.
In conclusion, while pork and chicken supply chains produce lower emissions than red meat per kilogram of meat, the intensive farming practices associated with these industries contribute to their environmental impact. To mitigate climate change, individuals can opt for lower-impact meats and reduce their overall meat consumption.

Pork and chicken are lower-impact meats
Meat consumption is linked to an annual carbon dioxide equivalent of 1.1 tons on a global average. In Europe, meat accounts for an average of 1.8 tons of carbon dioxide equivalent, and in North America, this figure rises to 4.1 tons. Pork and chicken are considered lower-impact meats compared to red meat, and substituting red meat with these alternatives can significantly reduce an individual's carbon footprint.
Pork
Pork has a lower environmental impact than red meat. Overall emissions from pork production range from 7 to 12 kg CO2-eq per kilogram of meat, which is less than a third of the emissions from beef. Pork has the third-highest environmental impact among meats, according to the Environmental Working Group (EWG). However, it is important to note that pork production emits lower carbon dioxide equivalents than beef, with 12.31 kilograms of CO2-eq per kilogram of meat for pork compared to 9 kilograms of CO2-eq per kilogram of meat for beef.
Chicken
Chicken is also a lower-impact meat compared to red meat. According to Poore and Nemecek's international study, poultry, including chicken, averages 6.0 kg CO2-eq per kilogram of meat. The EWG further breaks down American poultry into chicken (6.9 kg CO2-eq) and turkey (10.9 kg CO2-eq). Chicken has a smaller footprint than other meats, and switching from beef to chicken can reduce the climate impact of an individual's diet by half.
Plant-based alternatives
While pork and chicken are lower-impact meats, it is worth noting that plant-based alternatives generally have a lower carbon footprint. Pea-based alternatives, for example, emit just 1 kilogram of CO2-eq per kilogram, while tofu has a footprint five times lower than beef. Therefore, the most effective way to reduce one's dietary footprint is to eat less meat overall, especially red meat, and opt for plant-based alternatives.
