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.

CICERO-led study finds global warming effect of leaked hydrogen almost 12x stronger than CO2

Green Car Congress

A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2. The main changes in the radiative forcing due to 1 Tg flux of hydrogen; methane (green bars), ozone (yellow), stratospheric water vapor (purple), and aerosols (red).

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. Its implementation requires transfers from the regions that are less affected, or positively affected, by CO2 emissions to the countries that are negatively affected.

Cutting Non-CO2 Pollutants Can Delay Abrupt Climate Change; The Fast Action Climate Agenda

Green Car Congress

Noting the references in scientific and policy literature to the need for fast-action mitigation to help avoid DAI and abrupt climate changes, the authors define “fast-action” to include regulatory measures that can begin within 2–3 years, be substantially implemented in 5–10 years, and produce a climate response within decades.

of global CO2 emissions. Depending on future development, this could rise to 15% by 2050, according to a 2016 study by the Danish Shipowner’s Association (DSA) and UCL Energy Institute. In 2019, Maersk is planning to initiate open and collaborative dialogue with all possible parties to tackle climate change.

ORNL study finds aluminum-intensive vehicles can deliver up to 29% reduction in CO2 emissions compared to typical steel-bodied vehicle

Green Car Congress

Although a lightweight steel vehicle has a lower production phase environmental impact, those initial gains are erased by higher energy use and carbon emissions during the steel vehicle’s use phase, the study found. The modeling for this study conforms to internationally recognized standard practices (ISO 14040 and 14044).
