How does biofuel help agriculture and reduce air pollution?

The kind and supply-demand dynamics of biofuel can influence its potential to mitigate greenhouse gas emissions.

According to the majority of research, when fossil fuels are replaced with first-generation biofuels, greenhouse gas emissions are typically reduced by 20 to 60% as long as the most effective systems are employed and carbon dioxide emissions from changes in land use are not included (Greenfacts, 2017).

Again excluding carbon releases related to land-use change, second-generation biofuels and Brazilian sugar cane-derived ethanol typically reduce emissions by 70 to 90% (Greenfacts, 2017).

Biofuels can help agriculture by providing an additional source of income for farmers who grow biofuel crops. Additionally, biofuel production can lead to improved soil quality and reduced erosion. In terms of reducing air pollution, biofuels produce fewer greenhouse gas emissions compared to traditional fossil fuels when burned, thus contributing to lower levels of air pollution and mitigating climate change.
