Ecosystem Impacts and Productive Capacity of a Multi-Species Pastured Livestock System
This paper conducted a whole-farm life cycle assessment (LCA) of a multi-species pasture rotation (MSPR) farm in the southeastern United States that was originally converted from degraded cropland. Results showed an average of 2.29 Mg C ha−1 yr−1. Incorporation of soil C sequestration into the LCA reduced net GHG emissions by 80%, resulting in a footprint 66% lower than commodity production systems.
Carbon Footprint Evaluation of Regenerative Grazing at White Oak Pastures
Lifecycle analysis on White Oak Pastures’ beef. Results demonstrated that a pound of protein sequestered 3.5 pounds of CO2, in comparison to conventional beef which emitted 33 pounds of CO2 per pound of protein, or even Impossible Burger or Beyond Meat which emitted 3.5 pounds and 2 pounds of CO2 per pound of protein, respectively.
GHG Mitigation Potential of Different Grazing Strategies in the United States Southern Great Plains
This paper demonstrates that enteric emissions (methane) from cows are not a climate impediment when the animals are managed in a way that builds soil, thus, capturing carbon. Specifically, using a life cycle assessment that weighs emissions against sequestration, it calculates a net drawdown of approximately 2 tons of carbon per hectare per year (0.8 tons per acre per year) after a conversion from heavy continuous to multi-paddock grazing.
Potential mitigation of midwest grass-finished beef production emissions with soil carbon sequestration in the United States of America
This partial life cycle assessment (LCA) compared two grazing management strategies: 1) a non-irrigated, lightly-stocked, high-density system (MOB) and 2) an irrigated, heavily-stocked, low-density system (IRG). Results indicated that when soil carbon sequestration (SCS) potential was included, each grazing strategy could be an overall sink, with the MOB system found to have greater SCS than the IRG system.
Impacts of soil carbon sequestration on life cycle greenhouse gas emissions in Midwestern USA beef finishing systems
This paper does a greenhouse gas life cycle analysis (LCA) comparison of two grazing finishing systems in the Upper Midwest, USA: feedlot finishing and Holistic Planned Grazing, which the authors refer to as adaptive multipaddock (AMP). It finds that AMP finishing improved soil organic carbon by 3.5 tons per hectare per year. This resulted in a net negative footprint of 6.6 kg of carbon dioxide equivalence per kg of carcass-weight.
