UCL-led study finds climate impact caused by growing space industry needs urgent mitigation

Green Car Congress

The rapidly growing space industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study led by UCL and published in the journal Earth’s Future as an open-access paper. Locations and fuel types of rocket launches in 2019.

Harvard/Nanjing study: China’s war on PM2.5 pollution is causing more severe ozone pollution

Green Car Congress

pollution is falling, harmful ground-level ozone pollution is on the rise, especially in large cities. Ozone is the main ingredient in smog and has been studied since it began choking cities in the US in the early 1950s. Both NO x and VOCs are emitted from fossil fuel combustion, and VOCs can also be emitted from industrial sources.

MIT study finds including non-CO2 emissions from synthetic aviation fuel in lifecycle analysis of climate impact can lead to decrease in relative environmental merit; need for a holistic analysis framework

Aviation climate change impacts pathway. A new study by researchers at MIT has found that factoring the non-CO 2 combustion emissions and effects into the lifecycle of a Synthetic Paraffinic Kerosene (SPK) aviation fuel can lead to a decrease in the relative environmental merit of the SPK fuel compared to conventional jet fuel.

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. Hydrogen is not a greenhouse gas, but its chemical reactions in the atmosphere affect greenhouse gases such as methane, ozone, and stratospheric water vapor. Sand et al.

Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

The study will appear next month in the peer-reviewed journal Climatic Change Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. The study underscores the complex and sometimes conflicting ways in which fossil fuel burning affects Earth’s climate.
