How much meat does the average American eat annually? 50 pounds (20 kilograms)? 100 pounds (40 kilograms)? Not even close.

If we look just at the livestock “Big Four” — cows, chickens, pigs and sheep — the average American adult consumed 90 kilograms (198 pounds) of meat in 2014, according to data from the Organisation for Economic Co-operation and Development (OECD). The global average during that same year was 34 kilograms (75 pounds). By 2024, these numbers are projected to increase to 94.1 kilograms (207.5 pounds) per person in the U.S. and 35.5 kilograms (78.3 pounds) globally.

Thanks to all of this meat eating, at any given point in the year, there are 19 billion chickens, 1.5 billion cows, 1 billion pigs and 1 billion sheep on the planet — more than three times the number of people. And these numbers are set to rise as the human population grows and more people shift toward a meat-based diet. The number of cattle, sheep, goats and buffalo — animals that require quite a bit of land for feed production and grazing — alone is increasing by 25 million annually, according to the Food and Agriculture Organization.

Overall, global meat consumption is projected to increase more than 4 percent per person over the next 10 years. But as the maps below illustrate for a selection of countries and regions around the world, consumption won’t change equally across all types of livestock.

Looking again at the “Big Four,” consumption of poultry and sheep is predicted to rise 10.7 and 9.2 percent respectively, while the beef consumption is projected to remain stagnant and pork consumption will potentially see a 0.7 percent decline around the world compared with 2014 rates.

Why does all of this matter? Because while animal agriculture helps feed the planet, it also has a major impact on the environment. As ecologist Brian Machovina previously wrote at Ensia, “The livestock sector is responsible for approximately 15 percent of all human greenhouse gas emissions, about equivalent to all the direct emissions from transportation.”

Addressing climate change and other environmental challenges requires a better understanding of the parts of the world where meat consumption is predicted to increase — or decrease — over the coming years. And also a recognition that different kinds of livestock have different environmental footprints.

Where’s the Beef?

The map below featuring data from OECD highlights trends in global beef consumption. Of the countries and regions represented, the top five countries for the amount of beef consumed per person in 2014 were Argentina, Uruguay, Brazil, the United States and Australia. Between 2014 and 2024 the countries predicted to have the highest percentage increases in per capita consumption of those listed here are Vietnam, Mozambique, Tanzania, Turkey and Indonesia. The total annual per capita consumption of these five countries will still lag far behind the leader — Argentina, which is projected to consume 43.2 kilograms (95.2 pounds) per capita annually.

Poultry Planet

Poultry is — and will remain — the dominant form of livestock on the planet. As The Guardian recently reported, 52 billion chickens are slaughtered each year and this number is likely to rise as consumption increases in places such as China and India. At present the largest per capita consumers of chicken by weight of the countries featured here are Israel, the United States, Saudi Arabia, Malaysia and Australia. Over the next 10 years, Vietnam, Ukraine and China are projected to substantially ramp up consumption.

Pork’s Future Mixed



Globally, pork is projected to see a slight decline in the coming years. Of the major pork-consuming countries and regions, this decline will be the most pronounced in Canada, New Zealand and across the European Union. But not all countries are predicted to see declines. In 2024, the leader among the locations featured here will be Vietnam at 34.5 kilograms (76.1 pounds) per capita — a 19.9 percent increase over 2014.

Sheep Graze Higher

Among the four different types of livestock featured here, mutton and lamb will see the second largest percentage increase in per capita consumption between 2014 and 2024. At 1.9 kilograms (4.2 pounds) per capita consumption in 2024, mutton and lamb will still only constitute a small percentage of the global meat diet.

So what’s the takeaway message? As overall meat consumption continues to rise, the type of meat we consume makes a difference for the environment. As previously reported at Ensia, switching from beef to chicken or pork can significantly reduce diet-related greenhouse gas emissions. Choices we make while eating out or at the supermarket matter when it comes to the question of meat’s impact on the environment.
