A report from agricultural research institute, Rothamsted Research, concludes a tax on red meat to help curb climate change could do more harm than good.

Dr Taro Takahashi, agricultural economist at the University of Bristol and Rothamsted Research, who led the research​ said the economic losses will not only be borne by livestock farmers, but everyone in society.

Senior lecturer in sustainable livestock systems and food security at the Bristol Vet School, a member of the University's Cabot Institute for the Environment and a research scientist at Rothamsted Research, Dr Takahashi, said:

"Solely from the climate change perspective, our results unambiguously support everyone else's finding: that a red meat tax can reduce greenhouse (GHG) emissions.

"But unfortunately, this is only half the story, because the same tax could also force grazing livestock farms out of the industry – even when grassland is actually the most sensible land use at that particular location.

"As well as impacting consumers and farmers, the knock-on effects will be felt right along supply chains as well as rural communities that support and are supported by farmers."

The recently published UK National Food Strategy​ report called for a 30% reduction in meat consumption but steered clear of suggesting a meat tax, calling it "politically impossible".

This decision was met with strong criticisms by advocates of levy against ruminant farming because dairy, beef and lamb because they claim such systems cause greater GHG emissions than poultry, pork or plant-based foods.

However, whilst UK sheep and cattle are typically reared on grass, poultry and pigs are predominantly fed on cereals and with limited space available for agriculture, growing food for farm animals rather than people is often seen as an inefficient use of land, finds the Rothamsted Research report.

More nuanced approach called for  

Dr Takahashi said rather than a blanket tax, a better solution would be to look at which areas of the country are best kept as cattle and sheep farms, and which would be better turned to other uses such as cereal production, agroforestry and provision of ecosystem services.

"This would involve a more nuanced approach of weighing up the carbon savings against the amount of nutrients produced and the impacts on the economy, both locally and nationally."

The new study, published in Scientific Reports​, modelled economy-wide impacts of meat tax for the first time and estimated that, even under moderate tax rates previously proposed for the UK (19% for meat and 11% for dairy), the country’s economic losses would amount to £242m (US$336m) per year.

These losses resulted from transfer of land and labor forces from livestock farms to arable farms and non-agricultural industries.

The study found meat and milk production would decrease, with substantial GHG savings recorded both directly on farms and indirectly at connected industries, such as the manufacturing of agrochemicals.

Under the proposed tax, such climate change causing emissions were predicted to decrease by 2.5 Mt CO2 equivalent per year – equating to a monetized social benefit of £101m (US$140m) per annum under the same carbon price (£41/t CO2 equivalent) used to derive the assumed tax rates.

Advocates of a meat tax argue that economic models predict a significant reduction in GHG emissions as a result of taxation.

Macroeconomics impacts of livestock shrinkage

"However, many of these analyses do not consider wider effects of taxation beyond red meat and dairy markets, and as such the macroeconomic impacts associated with a shrinkage in the livestock industry were mostly unknown before this study,"​ said Dr Takahashi.

The next step for the research team is to identify when exactly grassland should remain grassland for sustainable food production, a task Dr Takahashi describes as "critical" for the future of UK agriculture.

"Given that we currently consume more livestock products than nutritionally recommended, it is perhaps socially suboptimal to maintain all of today’s grasslands for grazing purposes. The question, then, is under what soil, local climate and other geographical conditions are they desirable to society?

"We absolutely need to answer this question before telling a specific farmer to stop rearing livestock, because otherwise some unintended consequences are very likely."
