Which of the following statements about biodiesel blends is true?

Biodiesel blends are recognized for having lower emission rates compared to traditional heating oil. This is primarily because biodiesel is derived from renewable sources such as vegetable oils or animal fats, which leads to a cleaner combustion process. As a result, the use of biodiesel can significantly reduce emissions of harmful pollutants like carbon monoxide, particulate matter, and unburned hydrocarbons. Furthermore, when blended with traditional heating oil, these biodiesel blends maintain similar performance characteristics while offering environmental benefits.

This lower emission rate is particularly relevant as regulations and public concern about air quality and greenhouse gas emissions become more prominent. Hence, using biodiesel blends aligns with efforts to promote sustainable energy solutions in residential heating.
