Biofuels are carbon neutral.
Bio fuels are considered carbon neutral because they give off the same amount of carbon when burned that they absorb while growing. So, unlike fossil fuels (coal, oil and natural gas), they don't pollute the environment by adding extra CO2 to the atmosphere.
What else can I help you with?
Why do biofuels not contribute to global warming even though burning biofuels releases carbon dioxide?
Biofuels are part of the natural carbon cycle, in which plants absorb carbon dioxide from the air and this becomes carbon which is eventually returned to the air when vegetation rots or is burnt, or when animals eat it and respire carbon dioxide back into the air. Thus, although burning of wood and biofuels does release carbon dioxide back into the air, this process does not add to the long term concentration of atmospheric carbon dioxide. When we create carbon dioxide from carbon that has been sequestered underground, we add new carbon dioxide to the air, increasing its concentration and causing global warming.
Why biofuels don't cause a net increase in greenhouse gases?
Biofuels are considered to have a neutral impact on greenhouse gas emissions because they are made from renewable biological materials, such as plants, which absorb carbon dioxide during their growth. When biofuels are burned for energy, the CO2 released is roughly equivalent to what the plants absorbed, creating a closed carbon cycle. Additionally, biofuels can reduce reliance on fossil fuels, further decreasing overall greenhouse gas emissions. However, the net impact can vary based on factors like land use changes and cultivation practices.
Why carbon monoxide is neutral?
Carbon monoxide is considered neutral because it has one oxygen atom and one carbon atom, resulting in a balanced charge of zero. Its equal number of protons and electrons make it electrically neutral.
Is burning wood considered a carbon-neutral process?
Burning wood is not considered a carbon-neutral process because it releases carbon dioxide into the atmosphere, contributing to climate change.
Why is normal diesel not carbon neutral?
Normal diesel is not carbon neutral because it is a fossil fuel derived from crude oil, which releases carbon dioxide when burned. This carbon dioxide is a greenhouse gas that contributes to climate change by trapping heat in the atmosphere. To be carbon neutral, diesel would need to come from renewable sources that do not release additional carbon dioxide into the atmosphere.
Why are biofeuls described as carbon neutral?
Biofuels are considered carbon neutral because the carbon dioxide released when they are burned is equal to the amount of carbon dioxide the plants absorbed while growing. This creates a closed carbon cycle, where the carbon emitted is offset by the carbon absorbed during photosynthesis, resulting in no net increase in atmospheric carbon dioxide levels.
Are bio-fuels good?
Yes because they do not add polluting carbon dioxide to the atmosphere, causing global warming. (They release carbon dioxide that was recently removed from the air, so biofuels are carbon-neutral.)

Why are biofuels important?
Biofuels are important because they are a renewable resource, whereas there are limited reserves of carbon based fuels. Biofuels are also responsible for fewer carbon dioxide emissions.
What is produced when biofuels are burned?
carbon
Why are biofuels considered to be carbon neutral?

Why are bio fuels not completely carbon neutral?
Biofuels are not completely carbon neutral because of the entire lifecycle of their production process, which includes land use change, transportation, and processing. Emissions can also be released during harvesting, transportation, and processing of the raw materials used to produce biofuels. Additionally, the energy used in the production process and the impact of land-use changes can contribute to greenhouse gas emissions.
Are biofuels a renewable energy resource?
Yes. Biofuels are various kinds of vegetable mass, including vegetable oil. When the vegetation grew (usually in the past year), it removed carbon dioxide from the atmosphere. Now, when the biofuel is burnt, it releases the same carbon back into the atmosphere. This makes it carbon-neutral. Because the vegetation can all be grown again, it is counted as renewable.

How do biofuels lower carbon emissions?
The steady increase in carbon dioxide concentrations in the atmosphere come from our use of fossil fuels. If we were able to stop using fossil fuels, the amount of carbon dioxide in the atmosphere would stop rising. Biofuels are a partial answer, because by using biofuels you are reducing our use of fossil fuels.
Why aren't most bio fuels carbon neutral?
Most biofuels are not carbon neutral because the process of producing them often involves emissions from land use change, agricultural practices, and the use of fertilizers and pesticides. Additionally, the energy required to cultivate, harvest, and process the crops for biofuel production can contribute to greenhouse gas emissions.
Do Bio Fuels release sulfur dioxide?
Yes. I do not like using links from companies related to the biofuels industry, but in this case, I could not find any other information on the internet about how much sulfur dioxide is released from burning biofuels. It does get complicated, as there are all types of biofuels. The biofuels are reported as contributing much less air pollutants than diesel or gasoline, but they are not carbon (or sulfur dioxide, nitrogen oxide) neutral or zero emissions.
