Study finds automobile tires are a potential source of carcinogenic dibenzopyrenes to the environment

Green Car Congress

A new study by researchers from Stockholm University concludes that automobile tires may be a potential previously unknown source of carcinogenic dibenzopyrenes—a type of high molecular weight polycyclic aromatic hydrocarbon (PAH)—to the environment. 35% reinforcing agents/fillers such as carbon black or silica; and 15?20%

U-M study finds crop-based biofuels associated with net increase in GHGs; falsifying the assumption of inherent carbon neutrality

Green Car Congress

A new study from University of Michigan researchers challenges the assumption that crop-based biofuels such as corn ethanol and biodiesel are inherently carbon-neutral—i.e., This assumption has been used in cap-and-trade programs and carbon taxes as promulgated to date, which address only fossil-derived CO 2 emissions.

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). The study highlights the continued use of private jets last year despite the pandemic.

SEI study outlines risks to global low-carbon technology push

Green Car Congress

A new report from the Stockholm Environment Institute (SEI) finds that recent progress in developing and deploying low carbon technology is fragile, and advises that policy support must be stabilized globally to maintain momentum. The basis for the study is the concept of the “technological innovation system” (TIS) concept.
