Sustainability is a broad concept encompassing many aspects. Primarily, it concerns the CO₂ balance between the amount of CO₂ absorbed during growth through photosynthesis on the one hand, and the CO₂ emissions that occur during harvesting, supply, and use on the other. Although one could argue that only the amount of absorbed CO₂ is also emitted (which is why it is generally considered CO₂ neutral ), it is possible that the uptake and emission of CO₂ do not occur at the same time.

Thus, the question is how the amount of harvested biomass relates to the annual growth. In a system where increasingly more biomass is used, it is possible that temporarily more is emitted than is captured, until a new equilibrium is established (this is also known as carbon debt ). Consequently, the outcome of such an analysis depends heavily on the context.
