Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

of the human-made climate impact; two-thirds of this impact are caused by emissions other than CO 2 , according to a new study by researchers in Europe and the US. The study was published in the journal Atmospheric Environment. This new study is based on a thorough review of a decade of research on aviation emissions.

Study finds limiting warming to 2 °C would require at least a $200/t carbon tax globally

Green Car Congress

Some will suffer greatly from climate change, while others may even benefit. A study by University of Chicago economist Esteban Rossi-Hansberg, the Glen A. The social cost of carbon has become the standard measure to benchmark the magnitude of the carbon taxes needed to implement optimal carbon policy.

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

Green Car Congress

finds that private jets are 10 times more carbon-intensive than airliners on average, and 50 times more polluting than trains in terms of CO 2 emitted per passenger-km. The study highlights the continued use of private jets last year despite the pandemic. The report, Private jets: can the super-rich supercharge zero emission aviation?

T&E study finds plug-in hybrids show higher CO2 emissions than claimed

Green Car Congress

Unless you drive them softly, carbon emissions can go off the charts. Selling plug-in hybrids makes it easier for carmakers to meet their EU car CO2 standards as PHEVs are currently given additional credits. Plug-in hybrids are fake electric cars, built for lab tests and tax breaks, not real driving.
