ExxonMobil brings Kearl oil sands expansion online ahead of schedule; overall capacity doubling to 220K barrels per day

Green Car Congress

The PFT process removes a portion of the heavy end of the barrel (asphaltenes) using less energy than would be required to remove the same heavy ends in a coker at an on-site upgrader, thus reducing greenhouse gas emissions. This places oil sands within the same GHG intensity range as 45% of crude oil supplied to US refineries in 2012.).

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. and GHG emissions around 182 g CO 2eq /MJ fuel. They noted that an EBR of 1.2

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. Project rationale.

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

Average values for WTW GHG emissions for oil sands and other crudes, tight boundary. 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.

IISD Releases Five-Part Series of Reports on Removing Fossil Fuel Subsidies

Green Car Congress

This paper evaluates the state of information on fossil-fuel subsidies in a cross-section of countries that represent a range of governance systems, fossil-fuel markets and stages of economic growth. The full report will also cover Nigeria and Indonesia and will be released later in 2010. by 2010 to 18% by 2050.

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

Drive Electric

This is the sum of the emissions from raw materials, production, shipping, operation and end-of-life disposal – not just how clean it is to operate. If it’s manufactured on a ‘dirty’ power grid it becomes a major source of emissions over the EV lifecycle. In comparison, EV engines run on lithium batteries. THE BOTTOM LINE.

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

Drive Electric

For this reason, it’s not only the carbon emissions from using your vehicle to take into consideration but also the manufacturing process. If it’s manufactured on a ‘dirty’ power grid it becomes a major source of emissions over the EV lifecycle. In comparison, EV engines run on lithium batteries. Vehicle body and other car parts.
