Carbon Farming (definition) - Carbon Farming involves implementing practices that are known to improve the rate at which CO2 is removed from the atmosphere and converted to plant material and/or soil organic matter.

Regenerative Agriculture (definition) - Regenerative Agriculture is a system of farming principles and practices that increase biodiversity, enriches soils, improves water cycles, and enhances ecosystem services.

The Difference- Regenerative agriculture is the universal set of principles and practices aimed at improving biodiversity, enriching soils, and enhancing ecosystems.  Carbon farming utilizes regenerative agriculture practices aimed specifically at improving carbon sequestration.  In other words, carbon farming practices largely overlap with regenerative agriculture, but are a subset of the larger set of principles and practices that encompass regenerative agriculture.
