State Department issues Draft Supplemental Environmental Impact Statement on Keystone XL Pipeline: climate change impacts

Green Car Congress

Comparison of proposed Keystone XL route to previously proposed project segment. Aside from the potential construction and spill impacts of the pipeline, the scope of the climate change impacts have become the most contentious and politicized issue surrounding the pipeline.

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

Green Car Congress

This synthesis consumes only CO 2 and electricity, and is constrained only by the cost of electricity. Molten carbonate electrosynthesized boron-doped CNTs exhibit high electrical conductivity. Per ton CO 2 avoided, the C2CNT cement plant consumes $50 electricity, emits no CO 2 , and produces $100 cement and ∼$60,000 of CNTs.

Up close and personal with Volkswagen’s e-Golf carbon offset project: Garcia River Forest

Green Car Congress

In 2014, Volkswagen of America announced that starting with the launch of the zero-tailpipe emissions battery-electric 2015 e-Golf ( earlier post ), it would invest in projects to offset the carbon emissions created from the e-Golf on a full lifecycle basis: production, distribution and up to approximately 36,000 miles (57,936 km) of driving.

Study casting doubt on GHG benefits of corn stover ethanol draws sharp criticism by other researchers; Liska responds

Green Car Congress

A study published earlier this year in the journal Nature Climate Change that cast doubt on whether biofuels produced from corn residue could meet federal mandates for cellulosic biofuels to reduce greenhouse gas emissions by 60% compared to gasoline ( earlier post ) has drawn critical response published as correspondence in the same journal.

Gallium Nitride and Silicon Carbide Fight for Green Tech Domination

Cars That Think

Can advanced semiconductors cut emissions of greenhouse gases enough to make a difference in the struggle to halt climate change? Such a change is actually well underway. This conversion happens in your phone’s or laptop’s wall charger, in the much larger chargers and inverters that power electric vehicles, and elsewhere.
