Stavanger, 18 January (Argus) — A study by Norwegian authorities has found that the amount of biodiesel used in blends for road fuel in the country poses no more harm to public health than pure fossil fuel diesel. But any increase to the mandate could heighten health concerns.
The research, which was carried out by Norway's climate and pollution agency and the Norwegian institute of public health, found that biodiesel blends of up to 7pc would lead to similar health consequences as with regular diesel. But blends of up to 20pc and different combinations of biofuels, including the use of second-generation biofuels, would require further investigation.
Norway is considering raising the blending mandate for biodiesel to 5pc from 3.5pc this year. The blending mandate is then expected to gradually increase up to 2020, while the proportion of diesel vehicles using biodiesel in the Norwegian car market will rise to 70pc from 30pc, according to some estimates.
The study was conducted after scientists in other parts of Scandinavia raised concerns that the nanoparticles found in biodiesel could cause respiratory problems and cancer.
