ICCT study shows increased pollution from higher Indonesian biodiesel blends

January 13, 2021 |

In the UK, a new study from the International Council on Clean Transportation shows blending palm biodiesel in diesel fuel increases NOx emissions, and these effects are especially pronounced with LSD and common rail injection systems. The trend is statistically significant and suggests an increase in NOx emissions of 12%, 17%, and 41% for B30 (a 30% blend rate), B40, and B100 (pure biodiesel) in future years in Indonesia. Additionally, modern injection systems and fuels diminish the expected reductions of PM, CO, and HC from biodiesel compared to diesel fuel. Researchers note, however, that given the large variation in the dataset, there is uncertainty as to the precise magnitude of the biodiesel NOx effect.
