Climate-Neutral Beef, Dairy Could Reach Store Shelves by 2050, According to New Research
Authors pinpoint two key controls necessary for creating livestock that eliminates environmental impact of large-scale food production
The question of climate change is one of immediacy. According to the
“With the strain of hunger on our growing population, nutrient-dense foods like beef and dairy are important to have on the literal and figurative table,” said
“Talking about measuring emissions from an animal is different from, say, a tailpipe, whose measurement and control is straightforward,” said
Key findings of the paper include:
- Clear Metrics: It is important that climate metrics represent temperature change impacts across future emissions scenarios, quantifying GHG emissions by how they impact temperature over time. This is particularly important as the Paris Agreement is about limiting global temperature increases relative to pre-industrial times to well-below 2 degrees Celsius.
- Identification of Meaningful Impact: Most greenhouse gas emissions from live cattle production are non-CO2 gases, including methane (CH4) which is a short-lived gas. Controlling methane emissions will have a more immediate impact on temperature than gases that stay in the environment longer, such as CO2.
- Look to Feedyards and Beyond: The bulk of methane emissions from beef cattle production come from cattle on pastures and not those in feedyards. Innovations related to grazing cattle should be targeted, including delivering feed additives, and developing low-methane emitting breeding strategies.
-
Manure Management: For dairy production, enteric and manure methane emissions reductions will be critical, and can be influenced greatly through manure management techniques where the industry has already seen success. New manure management techniques, such as anaerobic biogas digesters, are one such strategy that is growing in importance in
California . The dairy industry within the state has already achieved a 25 percent reduction in manure methane emissions since 2013.
- Incentives: The best innovations work only with broad adoption and acceptance. Public and private partnerships as well as education and regulatory pathways will be critically important to support new innovation.
