Have you ever thought someone could be taxed – because a cow emits gases? It sounds like a joke, but this is a topic being seriously debated in one European country.
When I decided to focus my education on environmental studies, I didn’t fully understand the breadth of the field. At first, ecology meant reducing pollution, greening spaces, and caring for animals. However, after enrolling in university and starting to work in the field, my understanding of ecology quickly broadened. It was challenging to connect all the information and grasp how deeply ecology permeates all aspects of social life.
After several years of daily study, I began to uncover various, sometimes unexpected, facets of this topic. One of the latest issues I encountered truly intrigued me, and I’d like to share it with you.
Back in university, we discussed how greenhouse gases influence climate change, especially methane – a far more potent pollutant than carbon dioxide. I was surprised to learn that livestock farms, particularly those with cows, are major sources of these emissions. In addition to the water and land required for food production – which releases stored carbon – the animals themselves produce methane during digestion, which they emit through, to put it plainly, flatulence.
Yes, exactly – the manure and gases released by livestock are now the subject of one of the most unusual environmental measures I’ve come across. It’s a “fart tax” introduced by a country known for its innovation and environmental awareness – Denmark.
When I first heard about the methane tax on Danish farms, I must admit I laughed. However, as I started to research the topic, I realized this measure is far more serious and complex than it initially appears. That’s why I wanted to investigate what lies behind this policy and why a country like Denmark chose to take this step.
How Can a “Fart Tax” Affect an Entire Country?

This policy is formally known as a “flatulence tax” or Fart Tax and targets greenhouse gas emissions from cows, sheep, and pigs. Denmark has decided that, starting in 2030, farmers will pay a tax of 300 Danish kroner (about 43 USD) for emissions produced by their animals, calculated based on methane’s climate impact as if it were carbon dioxide. By 2035, the tax will increase to 750 kroner (about 106 USD).
What particularly caught my attention was the potential for farmers to receive a 60% tax refund. They can qualify for this refund by implementing measures to reduce methane emissions. My first thought was – how? Will the animals eat a diet that reduces gas production? As I dug deeper, I found out I was partially right. This reduction can be achieved by changing the animals’ diet, using specific feed additives, and employing technology that transforms manure into biogas, among other methods.
This raises the question: why did Denmark choose to implement such a policy specifically for the agricultural sector? The data I found shows that agriculture occupies around 65% of the country’s land, and Danish farms have five times more pigs and cows than people. This makes agriculture potentially the biggest climate polluter in Denmark.
Divided Opinions
Although this measure may seem beneficial at first glance, it has sparked a wide range of reactions. Some believe it’s politically motivated, claiming that farmers are an easy target for taxation, while larger polluters such as transportation and heating are avoided due to their political unpopularity. Even though farmers pay the tax, it’s believed the costs will ultimately fall on consumers through higher food prices. Others are concerned about the growing state control over production and the market, and they question the accuracy of emission calculations from farms.
I don’t know how effective this measure will be, what the real motives behind it are, or how valid the divided opinions may be. Still, the methane tax in Denmark raises an important issue – how can we truly reduce emissions in all sectors, including those often overlooked?
Interestingly, Denmark is not the first country to take this step. In 2022, New Zealand introduced a similar tax on agricultural emissions, but the new government later announced plans to abolish it following numerous complaints from farmers. This situation shows how sensitive and politically demanding such policies can be and raises the question – can such models survive in the long run?
We’ll have to wait and see whether Denmark will succeed in achieving tangible results and become a role model for other countries, or whether its fart tax will remain just another example of how complex and unpredictable the green transition can be.
