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 Source: Bond et al.

3 Oil Majors That Bet Big On Renewables

Green Car Congress

Indeed, much of Big Oil's reduction in greenhouse gas (GHG) emissions leans on the so-called natural gas bridge. BIT:ENI) recently unveiled what has been hailed as the most ambitious climate pledge yet by an oil supermajor. Eni has announced plans to cut down its greenhouse gas emissions by 80% over the next three decades.

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

Life-cycle GHG emissions from fossil and alternative sources of electricity. 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.

Fraunhofer, KIT study finds CO2 mitigation potential of higher-range PHEVs greater than expected

Green Car Congress

Further, they found that when the higher CO 2 eq emissions generated during the production phase of BEVs compared to PHEVs (due to the much larger BEV battery) are included in the analysis, a PHEV today shows higher CO 2 eq savings then BEVs compared to conventional vehicles. t of CO 2 eq) than for BEV (on average 2.6 t of CO 2 eq).

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). This is a powerful economic incentive, rather than economic cost, to mitigate climate change through a carbon negative process.

Tsinghua/Argonne Study Finds That Mass Use of EVs in China Could Result in Higher CO2 and Criteria Pollutant Emissions Than Conventional and Hybrid Gasoline Vehicles Due to Coal-Fired Generation of Electricity

Green Car Congress

Fuel-cycle SO 2 emissions of EVs compared to those of gasoline ICEVs and HEVs in China, current (left) and future (right). The study examined the fuel-cycle CO 2 , SO 2 , and NO x emissions of EVs in China in both current (2008) and future (2030) periods and compared them with those of conventional gasoline vehicles and gasoline hybrids.
