Study finds all-electric rideshare fleet could reduce carbon emissions, but increase traffic issues

Green Car Congress

Major ridesourcing companies Uber and Lyft have promised all-electric fleets by 2030 in an effort to reduce their carbon footprint. Overall, electrification reduces net external costs to society by 3–11% (5–24¢ per trip), depending on the assumed social cost of carbon. —Mohan et al. Mohan et al.

Smartphones and sensors as personal, real-time pollution monitors

Green Car Congress

This approach ignores big differences in air quality in school and work environments. The children also received small sensors, the micro-aethalometer model AE51, to measure black carbon levels simultaneously and continuously. We focused on black carbon as an indicator of traffic-related air pollution.

Two-year study in Canada finds large trucks disproportionately contribute to higher levels of black carbon pollution

Green Car Congress

A two-year study led by researchers at the University of Toronto has found large trucks to be the greatest contributors to black carbon emissions close to major roadways. Research consistently links traffic emissions to negative effects on both the environment and human health.

California ARB study finds commuters’ exposures to air pollution greatly depends on mode of travel; light rail, personal vehicles the lowest

Green Car Congress

The study, published recently in Atmospheric Environment , investigated commuter exposure to PM 2.5 , black carbon (BC), and ultrafine particles (UFP) in six common transport microenvironments in Sacramento, California. Click to enlarge. The ARB team found that UFP concentrations during bus, bicycling, and train commutes were 1.6–5.3

T&E: Rising use of private jets sends CO2 emissions soaring

Green Car Congress

CO 2 emissions from private jets in Europe increased by nearly a third (31%) between 2005 and 2019, rising faster than commercial aviation emissions, according to a new report from environmental campaign group Transport & Environment (T&E). Flying on a private jet is probably the worst thing you can do for the environment.
