Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. All sorts of scenarios have been developed under the assumption that carbon capture actually reduces substantial amounts of carbon. —Mark Jacobson.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

Schematic overview of the primary black-carbon emission sources and the processes that control. the distribution of black carbon in the atmosphere and determine its role in the climate system. Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1

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. 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. —Tom Wigley.

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. The space industry is one of the world’s fastest growing sectors.

Black carbon linked to increased cardiovascular risk; exacerbated by co-exposure to motor vehicle emissions

Green Car Congress

Black carbon (BC) from incomplete biomass and fossil fuel combustion is the most strongly light-absorbing component of particulate matter (PM) air pollution and a major climate-forcing emission. We wanted to identify the pollution sources that most impact human health to help inform these pollution control efforts.

Study estimates California’s GHG reductions since 2003 could be wiped out by 2020 wildfires

Green Car Congress

In an open-access report in the journal Environmental Pollution , researchers from UCLA and the University of Chicago estimate that California’s wildfire carbon dioxide equivalent (CO 2 e) emissions from 2020 (~127 mmt CO 2 e ) are approximately two times higher than California’s total greenhouse gas (GHG) emission reductions since 2003.

NUS researcher links air pollution to increased residential electricity demand

Green Car Congress

The study, set in Singapore, suggests that better air quality will bring about climate co-benefits in reducing electricity generation via lower household demand, and thus mitigating carbon emissions. This is important for policymakers when forecasting and influencing future emissions paths in the context of climate change.
