Meat production is responsible not for 18% but 51% of global greenhouse gas emissions, according to a study by a former lead environmental adviser to the World Bank and a current adviser. In a Worldwatch Institute report, Robert Goodland and Jeff Anhang argue that the methane, land use and respiration impacts of billions of farm animals have been underestimated .
They estimate that farm animals cause 32 billion tons of carbon dioxide equivalent, more than the combined impact of industry and energy. Lord Stern, former adviser to the British government on the economics of climate change, supported vegetarianism to lower carbon emissions.
