UC Riverside study finds emissions benefits for E15 blend in California

Green Car Congress

A study by a team from UC Riverside has assessed the potential of increasing ethanol content in California reformulated gasoline (CaRFG) by investigating the exhaust emissions from a fleet of 20 Tier 3 light-duty vehicles. Acetaldehyde and ethanol emissions responded strongly with ethanol across the fleet of 20 vehicles.

Emissions Analytics argues that current Pareto-efficient solution for decarbonization would be hybrids, not BEVs, based on do-no-harm

Green Car Congress

On this basis, and of Pareto efficiency, Emissions Analytics argues, until battery-electric vehicles can reach certain performance characteristics, government and industry support should switch immediately from EVs to full hybrids to create maximum welfare. The test cycle was made up of five repeats of the EQUA cycle, totalling 741 km.

ArcelorMittal publishes concept for global low-carbon emissions physical steel standard

Green Car Congress

ArcelorMittal published a concept for a low-carbon emissions steel standard to help incentivize the decarbonization of steelmaking globally and support the creation of market demand for physical steel products which would be classified as lower, and ultimately near-zero, carbon emissions steel. Dual scoring system.

Study finds GHG emissions from corn ethanol now 46% lower than gasoline

Green Car Congress

A new study by a team from Environmental Health & Engineering (EH&E) has found that greenhouse gas emissions from corn ethanol are 46% lower than those from gasoline—a decrease in emissions from the estimated 39% done by previous modeling. EH&E) and Adjunct Professor of Environmental Health at Harvard’s T.H. —Scully et al.

Emissions Analytics study shows GPFs make a big difference

Green Car Congress

A recent study by leading UK-based independent emissions testing company Emissions Analytics tested four apparently similar pairs of gasoline-fueled vehicles between the US (without gasoline particulate filters (GPFs)) and Europe (with GPFs). Average emissions across the four pairs of vehicles. Emissions Analytics.

Study finds high-density, low-rise cities such as Paris may be optimal urban form for reducing life cycle GHG emissions

Green Car Congress

A study by researchers at CU Boulder and Edinburgh Napier University finds that high-density, low-rise environments such as those found in Paris are the optimal urban form when looking to reduce greenhouse gas emissions over their whole life cycle. However, urban environmental design often neglects life cycle GHG emissions.

DOE tool allows consumers to estimate localized upstream greenhouse gas emissions for EVs and PHEVs

Green Car Congress

The US Department of Energy (DOE) has published a Beyond Tailpipe Emissions Calculator that provides estimates of total greenhouse gas (GHG) emissions associated with driving an electric vehicle (EV) or plug-in hybrid electric vehicle (PHEV), including emissions from the production of electricity used to power the vehicle.
