Researchers find two strains of diesel-eating bacteria in Antarctica

Green Car Congress

Researchers have identified two strains of diesel-degrading bacteria in pristine Antarctic soil and their optimal working conditions. Pollution from petroleum hydrocarbons such as diesel, which is widely used for heating, transportation and power generation poses a threat to wildlife in Antarctica.

Researchers clarify links between NOx and airborne sulfates to tackle hazy air pollution

Green Car Congress

Among pollutants that are less than 2.5 microns in diameter (PM2.5 ), airborne sulfate is one of the most common components of hazy air pollution formed atmospherically via the oxidation of sulfur dioxide (SO 2 ). Dense, hazy fog episodes characterized by relatively high humidity, low visibility and extremely high PM 2.5

T&E: tests show cars powered by electrofuels emit high levels of criteria pollutants

Green Car Congress

E-fuels are made by combining green hydrogen with CO 2 to produce liquid fuel that can be similar to gasoline or diesel used in conventional engines (as well as kerosene used in aviation). However, said T&E, particle pollution was far from eliminated. pollution. The emissions were compared to the standard E10 EU gasoline.

California Energy Commission awards nearly $70M to replace diesel school buses with electric school buses throughout state

Green Car Congress

The California Energy Commission approved nearly $70 million in funding to replace more than 200 old diesel school buses with all-electric buses that will reduce school children’s exposure to harmful emissions and help the state reach its climate and air quality goals. School buses are by far the safest way for kids to get to school.
