Which is better for the planet, cultivated meat or beef? It depends on how they're made. Cultivated meat uses less land and water but can emit more greenhouse gases if powered by non-renewable energy. Beef, on the other hand, takes up more land and water and produces high emissions, mainly due to livestock digestion and feed production.
Key differences:
- Cultivated meat: Grown in bioreactors, requires less land, but energy-intensive.
- Beef: Requires large land areas for grazing and feed and contributes heavily to emissions.
Quick Comparison:
| Factor | Beef Production | Cultivated Meat Production |
|---|---|---|
| Greenhouse Gas Emissions | High (from digestion, manure, and land use) | Lower with renewable energy, but can match or exceed beef with fossil fuels |
| Water Use | High (animals, feed, processing) | Lower (mostly for cleaning bioreactors) |
| Land Use | Extensive (grazing, feed crops) | Minimal (industrial facilities) |
Switching to renewable energy and improving production methods could make cultivated meat a lower-impact option in the future.
How Environmental Impacts Are Measured
Cradle-to-gate life cycle assessments are used to evaluate the environmental impact of food production systems. This approach examines every stage of production, from the extraction of raw materials to the point where the product leaves the factory. By standardising the methodology, researchers can make fair comparisons between different food production systems.
These assessments measure a variety of indicators, including greenhouse gas emissions (measured in kg CO₂e), water usage (litres), and land use (m²). They also track energy consumption, waste production, and air pollution at each step in the process.
For cultivated meat, the analysis covers several key phases: cell line development, the production and purification of growth media, cell cultivation in bioreactors, harvesting, and the initial stages of product processing[1][4].
Data Sources and Measurement Units
To ensure reliable results, environmental impact data is gathered from multiple sources. Peer-reviewed scientific studies form the backbone of these assessments, supplemented by industry reports and direct data from production facilities[4]. For conventional beef production, researchers often rely on agricultural databases and national statistics. In contrast, data on cultivated meat is derived from pilot plant operations, laboratory experiments, and techno-economic models[2][4].
A functional unit is used as the standard for comparison. Most studies adopt "per kilogram of edible, boneless meat" as their benchmark[1][4]. This eliminates inconsistencies that could arise from differences in bone weight or fat content.
To ensure accuracy, findings are validated through transparent reporting and sensitivity analysis, comparing the results against real-world data[4]. These consistent measurement practices are essential for analysing greenhouse gas emissions, water usage, and land use across different production systems.
Production Process Differences
Using these measurement methods, we can explore how production techniques lead to distinct environmental impacts. Conventional beef production is resource-intensive, requiring large amounts of land for grazing and growing feed crops. This contributes to significant greenhouse gas emissions, primarily from enteric fermentation and manure decomposition[4]. The process also demands substantial water resources and often leads to biodiversity loss due to land conversion.
In contrast, cultivated meat is produced in controlled bioreactors. This process relies on specialised growth media and a steady energy supply[1][3][5]. While it uses far less land, it is energy-intensive, particularly during the purification of growth media.
The environmental impact of cultivated meat is heavily influenced by the type of energy used. Research shows that switching to renewable energy can lower greenhouse gas emissions by up to 92% compared to beef[2]. However, if conventional energy sources are used, the carbon footprint can rise significantly, sometimes matching or even exceeding that of beef production[2][5].
One of the most challenging aspects of cultivated meat production is the purification of growth media. When conventional energy is used, emissions from this process can range from 246 to 1,508 kg CO₂e per kilogram of meat - 4 to 25 times higher than beef[1][3][5]. Developing technologies to reduce these purification requirements is a key focus for improving the environmental profile of cultivated meat[5].

Greenhouse Gas Emissions: Cultivated Meat vs Beef
The environmental impact of food production varies greatly between traditional beef and Cultivated Meat, influenced by factors like production methods, energy sources, and system boundaries. Studies highlight that beef production generates significant greenhouse gas emissions due to processes like enteric fermentation, manure handling, and land use changes. In contrast, the emissions from Cultivated Meat depend heavily on how it is produced and the energy sources involved.
Current Emission Data
Beef production is widely recognised as a major contributor to greenhouse gas emissions. On the other hand, Cultivated Meat has the potential to produce fewer emissions, but this largely hinges on the energy used. If renewable energy powers its production, emissions can be greatly reduced. However, reliance on conventional energy sources can result in emissions that are comparably high - or even higher. Additionally, specific production steps, such as purifying growth media, play a crucial role in shaping its carbon footprint.
Emission figures also vary depending on the scope of studies. Research that includes infrastructure and equipment tends to report higher emissions compared to studies focusing solely on operational activities.
Future Emission Reductions
As the technology behind Cultivated Meat evolves, its environmental impact is expected to decline. A shift towards renewable energy sources like solar, wind, and hydroelectric power will be vital in curbing greenhouse gas emissions. Moreover, advancements in production methods - such as refining growth media formulations and improving energy efficiency - will help streamline energy-heavy processes like sterilisation and temperature regulation.
Scaling up from pilot projects to fully optimised commercial production facilities is another key factor. Larger-scale operations are likely to improve energy use efficiency. In regions like the UK, where the electricity grid is becoming increasingly low-carbon, these improvements could make the environmental benefits of Cultivated Meat even more evident.
With greenhouse gas emissions covered, the next step is to examine the water and land use impacts of Cultivated Meat and beef, providing a more complete picture of their environmental trade-offs.

Water Use and Land Use: Resource Requirements Compared
When it comes to resource efficiency, beef and Cultivated Meat production differ significantly, especially in terms of water and land use. These two factors are crucial not just for resource management but also for their broader environmental impact. By comparing these aspects, we can better understand the potential for more sustainable food production.
Water Requirements
Producing traditional beef involves substantial water use across multiple stages. Cattle require water for drinking, while growing feed crops often demands irrigation, particularly in drier regions. Additionally, water is used in processing for cleaning and cooling. In the UK, where rainfall is plentiful, irrigation needs may be lower compared to more arid areas, but water use still remains an important consideration.
Cultivated Meat production, on the other hand, uses water primarily for tasks like cleaning bioreactors, sterilisation, and cooling. Since there are no animals to hydrate or crops to irrigate, this method has the potential to drastically reduce water consumption. However, the extent of these savings depends on the specific technologies and designs employed in production facilities.
Land Requirements and Biodiversity Effects
Conventional beef farming demands extensive land for grazing and growing feed crops. In many cases, feed is imported, which expands the environmental footprint beyond local borders. This large-scale land use can strain ecosystems and negatively affect biodiversity.
Cultivated Meat is produced in controlled industrial environments, requiring far less land. This smaller land footprint creates opportunities to restore natural habitats, which could benefit biodiversity compared to the intensive agricultural landscapes required for cattle farming.
Water and Land Use Comparison Table
| Resource | Beef Production | Cultivated Meat Production | Potential Reduction |
|---|---|---|---|
| Water Use | High – needed for animals, feed crops, and processing | Lower – primarily for facility operations, with recycling potential | Significantly lower |
| Land Use | Extensive – for grazing and feed production | Minimal – limited to industrial facilities | Dramatically lower |
| Feed Crop Land | Essential for growing animal feed | Not required | Eliminated |
| Biodiversity Impact | Variable – intensive feed production can harm ecosystems | Minimal direct impact – potential for habitat restoration | Potential for positive impact |
These efficiency gains are particularly relevant in the UK, where managing water resources and optimising land use are critical for agricultural policy.

Using renewable energy sources - such as wind, solar, or hydropower - can slash greenhouse gas emissions by more than 80%, positioning cultivated meat as a much greener alternative to conventional beef.
On the other hand, if production depends on fossil fuels or other energy sources with high emissions, its carbon footprint could rise, undermining the environmental benefits it offers compared to traditional meat. Shifting to cleaner energy is crucial to fully realise the potential of cultivated meat as a sustainable option.
What are the key challenges for cultivated meat in achieving a lower carbon footprint than beef?
Cultivated meat faces a tough road when it comes to cutting down its carbon footprint compared to beef. One of the biggest issues is its energy-heavy production process, especially the reliance on highly refined growth media. This alone contributes a lot to emissions, and in some instances, the overall carbon footprint can actually surpass that of traditional beef.
Another significant obstacle is scaling up production. With the technology available today, ramping up manufacturing could lead to even higher emissions, making it harder to meet sustainability targets. Tackling these challenges will demand improvements in production methods and the use of more eco-friendly materials.
What is cradle-to-gate life cycle assessment, and how does it help compare the environmental impacts of cultivated meat and beef?
A cradle-to-gate life cycle assessment (LCA) examines the environmental impact of a product, starting from the extraction of raw materials up until it leaves the production facility. This approach takes into account factors like greenhouse gas emissions, water consumption, and land use, providing a comprehensive view of a product's environmental footprint.
When comparing cultivated meat with conventional beef, LCAs reveal striking differences in how resources are used. Thanks to its innovative production methods, cultivated meat tends to have a smaller environmental impact, bypassing many of the resource-heavy steps involved in traditional meat farming.
