What is required for biomass to be considered carbon neutral?

For biomass to be considered carbon neutral, new growth must completely offset carbon losses. This concept is rooted in the idea of a balanced carbon cycle. When biomass, such as trees or plants, is used for energy, it releases carbon dioxide (CO2) into the atmosphere. However, if new biomass is grown to absorb an equivalent amount of CO2, then the net effect on atmospheric CO2 levels can be neutral. This dynamic means that sustainable management of biomass resources is essential to ensure that the carbon emissions generated during energy use are effectively countered by the growth of new biomass that sequesters carbon.

The other options do not align with the requirements for carbon neutrality. Sourcing from endangered species can lead to biodiversity loss without contributing to carbon neutrality. Seasonal harvesting does not inherently affect the carbon neutrality—what matters is the overall carbon balance. Finally, prohibiting biomass from being used for energy contradicts the principle of utilizing biomass as a renewable and potentially carbon-neutral energy source, provided that it is managed sustainably.
