Advances in food processing have made meat available in a variety of forms, including fresh and frozen. This has led to a growing interest in sustainable diets, as it has been shown that the increase in meat consumption affects both our health and the environment. In fact, the consumption of beef is closely linked to the environment: the amount of methane emitted by a single cow is estimated to be around 47 kg per year, and 15-20% of all atmospheric methane comes from animal agriculture. The increased number of livestock due to the increase in meat consumption generates huge amounts of manure. Due to its high content of organic matter and nitrogen, livestock manure causes soil and water pollution. As a result, there is are many ongoing discussions about meat taxes, also known as sin taxes in Europe. Sin taxes are taxes imposed to reduce consumption of certain things that have a negative impact on society, which includes tobacco taxes, sugar taxes, etc. Meat taxes are another example of an effort to change meat-oriented eating habits with the main objective of protecting the environment. However, it is important to recognise that the introduction of such taxes may lead to compensatory behaviour in people and create a perverse incentive to consume meat. Therefore, we will review the opinions and current situation of meat taxes and introduce considerations that can help individuals make the transition to a more sustainable diet.
