Study finds sustainable aviation fuels show up to 70% reduction in particle mass emission compared to fossil fuel

Green Car Congress

A comparison to in-flight emission data showed similar trends at cruise altitudes. during idle and taxi). Therefore, when selecting and mixing SAF blends to meet present fuel-certification standards, attention should be paid to minimizing complex aromatic content to achieve the greatest possible air quality and climate benefits.

Study suggests high-mileage light-duty fleets contribute higher emissions and emissions share than expected

Green Car Congress

One segment of the on-road fleet that is believed to drive more miles and consume more fuel than the average fleet vehicle is livery (for-hire) vehicles, such as taxis and limousines. The researchers used the West LA data as a baseline for comparison with the high-mileage fleet measurements. In their study, Bishop et al.
