T-3A1-A-1 - Enteric Fermentation from Cattle

Definition¶

This emission source is defined by the IPCC in E-3A1a - Cattle

Sustainability Category: Red¶

Red

This activity significantly contributes to greenhouse gas emissions and undermines climate mitigation efforts. The activity should be phased out or fundamentally transformed, with financing directed toward decommissioning, replacement with sustainable alternatives, or radical decarbonization where elimination is not immediately feasible.

Transition Elements¶

This activity has the following mitigation options modelled as transition elements:

T-3A1-TE-1 - Shift to Sustainable Healthy Diets
