Does the burning of biomass give out greenhouse gases?

So, it does? I guess my lesson was too general; it said that renewable sources of energy don't release greenhouse gases.
Yes, burning of biomass can release greenhouse gases into the atmosphere. When biomass, such as wood, crops, and agricultural residues, is burned, carbon dioxide (CO2) is released. CO2 is a key greenhouse gas that contributes to global warming and climate change.
To understand why burning biomass emits greenhouse gases, we need to consider the carbon cycle. When plants grow, they absorb CO2 from the atmosphere through photosynthesis. This carbon is stored in the biomass, effectively removing it from the atmosphere. However, when the biomass is burned, the stored carbon is released back into the atmosphere as CO2. This process is known as carbon dioxide emissions from biomass combustion.
To estimate the amount of greenhouse gases emitted from burning biomass, it is necessary to consider the type and quantity of biomass, as well as the efficiency of the combustion process. Different biomass fuels and burning techniques can result in varying emissions. For accurate calculations, scientific analyses typically take into account factors like the carbon content of the biomass, the combustion efficiency, and any additional emissions from combustion byproducts.
Overall, while biomass burning can be a renewable energy source, it still contributes to greenhouse gas emissions. To mitigate its environmental impact, it is essential to promote sustainable practices, such as using biomass from sustainably managed sources and increasing the efficiency of biomass combustion technologies.
