Lifecycle study finds LNG can reduce shipping GHG emissions by up to 21%

Green Car Congress

A lifecycle study by consultancy thinkstep, commissioned by SEALNG and SGMF, has found that greenhouse gas (GHG) reductions of up to 21% are achievable now from LNG as a marine fuel, compared with current oil-based marine fuels, over the entire life-cycle from Well-to-Wake (WtW). Source: thinkstep. Others (5%).

Smith School lifecycle study highlights importance for algae-derived biodiesel of co-product utilization and optimizing and decarbonizing every step of the supply chain

Green Car Congress

However, biodiesel from advanced biomass has an inherent environmental advantage of greenhouse gas (GHG) emissions reduction that can be realized once every step of the production chain is fully optimized and decarbonized, the researchers said. Currently, algae-derived-biodiesel is up to 2.5 and GHG emissions around 182 g CO 2eq /MJ fuel.

State Department releases final environmental impact statement on Keystone XL Pipeline Project; analysis of GHG emissions

Green Car Congress

As part of the analysis, DOS commissioned a detailed study of greenhouse gas life-cycle emissions that compared Canadian oil sands crude with other selected reference crudes. This range is equivalent to annual greenhouse gas emissions from the combustion of fuels in 588,000 to 4,061,000 passenger vehicles. —FEIS. The pipeline.

IHS CERA meta-analysis finds lifecycle GHG emissions for fuel produced solely from oil sands crude average 11% higher than from average crude refined in the US; high variability

Green Car Congress

When the oil sands products refined in the United States are considered—a mixture of oil sands and lower-carbon blending components—the GHG emissions are, on average, 9% higher than the average crude processed in the US. IHS CERA compared 12 sources in its meta-analysis.

EV myths busted: Are electric vehicles actually good for the environment?

Drive Electric

Electric vehicles typically have a smaller operating carbon footprint than gasoline cars, even when accounting for the electricity used for charging. With the full cradle-to-grave life cycle in mind, the question becomes: does an EV have a smaller carbon footprint over its lifetime than an ICEV? Manufacturing an Electric Vehicle.
