An international team of researchers has, for the first time, estimated the amount of methane (CH4) and nitrous oxide (N2O) that countries release into the atmosphere when producing meat from livestock, and assigned the emissions to the countries where the meat is ultimately consumed.
They found that embodied, or "hidden", emissions in beef, chicken and pork have increased by 19% over the past 20 years, and that there is currently a global instability caused by a large number of countries contributing to the production of emissions in another country.
