Organic meat is NO better for the environment than regular meat and produces the same amount of greenhouse gas emissions, study finds
- Experts from Germany calculated the environmental impact of different meat
- Organic farming reduces emissions in not using fertilizer-grown animal feed
- Yet the slow growth rates and diminished yields serve to counter these savings
- In fact, the team found organic chicken produces slightly more emissions overall
- The researchers call for a new tax that reflects the environmental costs of meat
The same amount of greenhouse gas emissions result from the production of organic meat as regular meats, a study has concluded.
Researchers from Germany calculate the emissions produced during the manufacture of regular and organic meat, as well as plant-based foodstuffs.
Organic and regular beef are just as environmentally damaging, they concluded — while organic chicken actually results in slightly more greenhouse emissions overall.
Based on their findings, the team propose that policy measures — ‘meat taxes’ — are needed to ‘close the gap between current market prices and the true costs of food.’
Such taxation, the team said, would call for a 40 per cent increase in regular beef’s cost, but only a 25 per cent rise for organic beef, which is already more expensive.

In their study, politics and technology researcher Maximilian Pieper of the Technical University of Munich and colleagues worked to calculate the external climate costs — specifically as regards greenhouse emissions — of various foodstuffs.
The team sorted the products that they analysed into one of three-categories. These included conventional meat production, organic meat production and plant-based food production.
They then took an account of the emissions produced during the stages of each production process — including those released during growing and the processing of feed and fertiliser, for example, and methane given off by animals and manure.
The team found that while organic meat saw emissions reductions in some areas — such as by not using fertiliser to grow the necessary animal feed — these savings were typically offset by increased methane emissions from the animals themselves.
This complication arose as a product of both the slower growth rates of the animals and the fact that they tend to produce less meat per individual — meaning that organic farms must raise more animals to meet the same level of demand.
The team found, specially, that organic and regular beef result in the same net level of emissions — while organically-grown chicken actually produces more emissions than when the meat is reared conventionally.
In contrast, however, organic pork was found to result in slightly less emissions than produced by the manufacture of regular pork.

‘As the results show, the production of animal-based products — especially of meat — causes the highest emissions,’ the researchers wrote in their paper, noting that the findings are consistent with the findings of various previous studies.
‘Such high emissions stem from the resource intensive production of meat, because of an inefficient conversion of feed to animal-based products,’ they added.
‘Organic regulations prescrib(e) a certain amount of land per animal, which is higher compared to average conventional production, as well as a higher living age and lower productivity of organically produced feed and raised animals.’
This counterbalances or even reverses the described positive aspects of organic animal farming,’ they concluded.
The full findings of the study were published in the journal Nature Communications.
WHY ARE COWS BAD FOR THE ENVIRONMENT?
The livestock animals are notorious for creating large amounts of the gas, which is a major contributor to global warming.
Each of the farm animals produces the equivalent of three tonnes of carbon dioxide per year and the amount of the animals is increasing with the growing need to feed a booming population.
Methane is one of the most potent greenhouse gases, trapping 30 times more heat than the same amount of carbon dioxide.
Scientists are investigating how feeding them various diets can make cattle more climate-friendly.
They believe feeding seaweed to dairy cows may help and are also using a herb-rich foodstuff called the Lindhof sample.
Researchers found a cow’s methane emissions were reduced by more than 30 per cent when they ate ocean algae.
In research conducted by the University of California, in August, small amounts of it were mixed into the animals’ feed and sweetened with molasses to disguise the salty taste.
As a result, methane emissions dropped by almost a third.
‘I was extremely surprised when I saw the results,’ said Professor Ermias Kebreab, the animal scientist who led the study.
‘I wasn’t expecting it to be that dramatic with a small amount of seaweed.’
The team now plans to conduct a further six-month study of a seaweed-infused diet in beef cattle, starting this month.
