This study empirically investigates the effect of meat consumption on greenhouse gas emissions (carbon dioxide, methane, and nitrous oxide) in the USA. The impact of meat consumption on greenhouse gas emissions is examined by controlling for economic growth and energy consumption. The empirical analysis finds that all these variables are cointegrated for the long run. Moreover, meat consumption aggravates greenhouse gas emissions. Specifically, meat consumption (except for beef) has a U-shaped relationship with carbon emissions and an inverted U-shaped relationship with methane and nitrous oxide emissions. The causality analysis indicates a unidirectional causality running from meat consumption to greenhouse gas emissions. These empirical findings indicate that the US livestock sector has the potential to become more environmentally friendly with careful policy formulation and implementation.
本研究实证考察了美国肉类消费对温室气体排放（二氧化碳、甲烷和氧化亚氮）的影响。通过控制经济增长和能源消耗，检验了肉类消费对温室气体排放的影响。实证分析发现，这些变量在长期内都是协整的。此外，肉类消费加剧了温室气体排放。具体而言，肉类消费（牛肉除外）与碳排放呈 U 型关系，与甲烷和氧化亚氮排放呈倒 U 型关系。因果关系分析表明，从肉类消费到温室气体排放存在单向因果关系。这些实证结果表明，美国畜牧业具有通过谨慎的政策制定和实施变得更加环保的潜力。
