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

3 Oil Majors That Bet Big On Renewables

Green Car Congress

Further, Equinor plans to reduce its net carbon intensity by at least 50% by 2050 by deploying CCUS (Carbon Capture, Utilization, and Storage) and hydrogen technologies. #2 As we have pointed above, ENI has the most ambitious climate change pledge with plans to lower its greenhouse gas emissions by 80% by 2050.

GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

Stuart Licht ( earlier post ) have developed a new process that transforms CO 2 into a controlled selection of nanotubes (CNTs) via molten electrolysis; they call the process C2CNT (CO2 into carbon nanotubes). Molten carbonate electrosynthesized boron-doped CNTs exhibit high electrical conductivity. —Ren et al.

New Catalytic Pathway for the Reduction of CO2 to CO Under Mild Conditions

Green Car Congress

The reaction for carbon dioxide splitting into carbon monoxide with aromatic aldehydes as oxygen acceptors. Carbon dioxide, however, is highly stable, and splitting the O=C(O) bond to generate carbon monoxide requires large energy input. Article ASAP doi: 10.1021/ja909038t. Credit: ACS, Gu and Zhang.

I’ve Done The Math – Now I’m Doing Something About It

Creative Greenius

And so it is that I resigned from my position as Director of Strategic Partnerships and Public Affairs for CBS EcoMedia effective the first of this month and I will now be devoting my full time to working on climate change response with the South Bay 350 Climate Action Group, the South Bay Bicycle Coalition and 350.org.

Researchers Say Mix of Policies and Current or Near-Term Technologies Could Phase Out US CO2 Emissions from Coal-Fired Power Plants by 2030

Green Car Congress

Lead author Kharecha and colleagues note that current climate science indicates that atmospheric CO 2 concentrations, already at 387 ppm in 2009 and rising, need to be reduced to no more than 350 ppm. Technol Articles ASAP doi: 10.1021/es903884a. A first step is to remove fossil fuel subsidies. Kharecha et al. Kharecha et al.

New Molecule Could Lead to New CO2 Capture Methods

Green Car Congress

An unusual bowl-shaped molecule that pulls carbon dioxide out of the air may provide new possibilities for dealing with global warming. Tossell of the University of Maryland notes in the new study that other researchers (Brooks 2006) discovered the molecule—a macrocyclic amidourea—while doing work unrelated to global climate change.
