A study led by environmental health scientists at Columbia University Mailman School of Public Health examined the release of vapors from gasoline station vent pipes, and found benzene emissions were 10 times higher than estimates used in setback regulations that determine how close schools, playgrounds, and parks can be to the facilities.

They used the model and the data to estimate the life cycle air pollution, greenhouse gas, and traffic externality benefits and costs of serving rides based on Chicago TNC trip data from 2019 to 2022 with fully electric vehicles. The authors acknowledge funding from Carnegie Mellon University’s Wilton E. Scott Institute for Energy Innovation.

A study by European researchers has found that two-stroke (2S) scooters, although constituting a small fraction of the fleet, can dominate urban vehicular pollution through organic aerosol and aromatic emission factors up to thousands of times higher than from other vehicle classes. Emission factors (EFs) from scooters and other vehicles.

Source: Emissions Analytics The testing showed that the Kia’s gasoline particulate filter reduced particle mass to almost zero, and particle number to 97% below the Euro 6 regulatory limit. Every air pollutant is more than 90% its limit. In absolute terms, the increased tire wear from the Tesla over the Kia was 11 mg/km—2.4

Comparisons of life-cycle emissions from LUC phase for (a) sugar cane ethanol and (b) soybean biodiesel. The pollutants are NMHC, CO, NO x , TPM, PM 2.5 The climate effects of land-use changes from increasing biofeedstock acreage, both indirect and direct, have dominated policy discussion, and focused on comparisons in long-lived GHGs.

Environmental impacts of gasoline and E85. In a similar way, the full breadth of impacts attributable to conventional gasoline production, such as natural resource consumption and hazardous pollutant emissions, must also be considered in order to make balanced comparisons to biofuels.

Multiple sensor insertions are possible—depending on the pipe configuration, a gasoline engine can feature four oxygen sensors, two of which serve an on-board diagnostics function to check for correct operation, although a diesel engine still has only one oxygen sensor, located before the diesel oxygen catalyst.
