According to the World Meteorological Organization, global emissions are projected to reach a staggering 41.6 billion metric tons of CO₂ equivalent (CO₂e).
Can you guess how much of this comes from meat and dairy production? Brace yourself—the answer is shocking: 14.5%!
Yes, you read that right. According to the United Nations' Food and Agricultural Organization (FAO), meat and dairy contribute more greenhouse gases than the entire transportation sector combined.
If we are to control global emissions and keep global warming below 2°C, tackling emissions from cattle farming is critical. That’s precisely what Switzerland-based agricultural technology company Syngenta Global AG aims to address in partnership with McDonald's and their beef supplier, Lopez Foods.
Before we dive into how Syngenta plans to achieve this, let’s explore why cattle farming is such a significant contributor to global greenhouse gas (GHG) emissions:
Why Cattle Farming Drives Emissions
Digestion
Cattle are ruminants, meaning their digestive systems ferment food in their stomachs. This process produces methane (CH₄), a greenhouse gas 28 times more potent than carbon dioxide (CO₂) at trapping heat over 100 years. Each cow emits approximately 220 pounds of methane annually.
Manure Management
The decomposition of manure releases both methane and nitrous oxide (N₂O), another highly potent greenhouse gas. How manure is managed—whether stored in lagoons, spread on fields, or composted—significantly impacts the amount of GHGs released. Improper management can lead to substantial emissions.
Land Use Change
Expanding cattle farming often requires converting forests and grasslands into pastureland. This not only releases stored carbon dioxide (CO₂) but also reduces the planet’s capacity to absorb CO₂, exacerbating climate change.
Resource-Intensive Production
Cattle farming demands significant resources, including large amounts of feed, water, and land. Producing beef requires 20 times more land and emits 20 times more GHGs per gram of edible protein compared to plant-based proteins like beans.
Syngenta’s Solution: Enogen Corn
Syngenta is targeting digestion-stage emissions with its innovative Enogen Corn variety. This crop features a unique alpha-amylase enzyme that speeds up the conversion of starch into sugars, making it easier for cattle to digest. Research shows that feeding cattle Enogen improves feed efficiency by approximately 5%, translating to reduced GHG emissions per pound of beef produced.
The Impact
The partnership between Syngenta, McDonald's, and Lopez Foods is projected to reduce emissions by over 164,000 metric tons of CO₂ annually. For example, feeding Enogen to just 1,000 cattle could lower emissions by 196 tons per year, save 69 acres of land, and conserve 6 million gallons of water annually.
A Sustainable Future for the Food Industry
The environmental toll of meat and dairy production is undeniable, but innovative solutions like Syngenta’s Enogen Corn offer a glimpse of hope. By tackling emissions at the source, partnerships like the one between Syngenta, McDonald’s, and Lopez Foods demonstrate how technology can drive sustainable change in the food industry.
So, as we work toward a greener future, one question remains: could innovations like this reshape the entire food system and help us meet global climate goals?
