Global estimates of emissions by species

According to a report from Environmental Working Group, if a four-person family skips meat and cheese one day a week, it's like taking car off the road for five weeks.

The process of rearing, processing, transportation and cooking livestock products affect climate change by releasing carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O).

The bar chart below shows the global estimates of emissions by species. It is obviously that Beef cattle produces the largest amounts of emissions.

Notes:

(1) This graph icludes emissions attributed to edible products and to other goods and services, such as draught power and wool.

(2) Beef cattle producing meat and non-edible outputs.

(3) Dairy cattle producing milk and meat as well as non-edible outputs.
