not reformulated) gasoline; and (4) crude oil production is 100% conventional crude (most oilsands production occurs outside of our spatial modeling domain—i.e., They excluded emissions occurring outside of the contiguous US and surrounding waters) from the results below. the contiguous US).
As a result, the GREET team is now using the new software (called GREET.NET to differentiate from GREET Excel) as a new platform for life cycle assessment studies and database management. Added water consumptions for the major pathways as an additional life-cycle analysis metric. Incorporated marine vessel module.
As we try to objectively study nature, we are often reminded of how natural forces affect us personally. When we turn up the heat in our homes and workplaces, we must balance our personal need for warmth with the global impact of burning fossil fuels like oil, gas, coal, and biomass. There is nothing special here!”
Peabody Energy and GreatPoint Energy signed an agreement to pursue development of coal-to-gas and coal-to-hydrogen projects in the United States and around the world with carbon capture and storage (CCS) that would achieve near-zero carbon emissions, while increasing the production of stranded oil via enhanced oil recovery.
