Food consumption emissions remain stubbornly high, partly due to the cheese paradox. Producing hard cheese requires significant amounts of milk, which drives up methane and other greenhouse gas emissions associated with livestock farming. Switching to alternative protein sources and plant-based dairy could significantly lower the climate impact of diets. This shift is essential for meeting broader sustainability goals and reducing the overall environmental footprint of the agrifood sector.

The article mentions the cheese paradox and high milk requirements for hard cheese, but it does not provide the specific emission delta between traditional cheese and the alternatives it suggests. We need the actual numbers to see if the impact is material.
Even with the numbers, the real issue is the incentive structure. Without a carbon tax on livestock or subsidies shifting toward plant proteins, consumer behavior will not change fast enough to hit climate targets.
I wonder about the energy intensity of the alternative protein plants. If we swap cow methane for industrial processing powered by a dirty grid, we are just moving the emissions from the field to the plant.
Fair point, but most LCA data shows plant based alternatives still win by a wide margin on carbon. The methane from enteric fermentation is a much bigger immediate problem than the electricity used in a factory.
