On the carbon neutrality characteristics of biofuels
Nowadays, when it comes to biofuels, it is often said that they are a fuel source of complete carbon neutrality. This theory is inherently reasonable, but it is also necessary to clarify its essence.

Biofuels are derived from biomass, such as plants, algae, etc. When they grow, they absorb carbon dioxide from the atmosphere through photosynthesis and fix it in the body. And when they are converted into fuel and burned, although carbon dioxide is re-released, from a cyclic perspective, it seems to be called carbon neutrality.

When looking at the reality carefully, there are also many complex situations. First, the cultivation process of biomass may require the application of chemical fertilizers and pesticides, which all involve energy consumption and carbon emissions. Second, the processing and conversion process of biofuels, from raw material collection, transportation to refining, also requires energy, and most of them are dominated by traditional fossil energy, which also increases carbon emissions. Furthermore, the change of land use to planting biomass may cause changes in the carbon storage of the original ecosystem, resulting in additional carbon emissions.

Therefore, although biofuels have the potential to approach carbon neutrality, they are called a fuel source of complete carbon neutrality, which should be treated with caution. When comprehensively considering its entire life cycle of carbon emissions, comprehensive trade-offs can be made clear in the energy transition and carbon emission reduction industry in the real utility and value, must not only be based on the appearance and make a sharp judgment.
