Argonne study finds shale gas GHG lifecycle emissions 6% lower than natural gas, 23% lower than gasoline and 33% lower than coal; upstream methane leakage a key contributor

Green Car Congress

Gasoline section shows results for fuel derived from both conventional oil and oil sands. We used the GREET (Greenhouse gases, Regulated Emissions, and Energy use in Transportation) model, which can analyze more than 100 fuel pathways, to perform our simulations. Expansion bars show the components of fuel production.

Researchers describe the “where” and “when” of life cycle emissions from gasoline and ethanol in the US

Green Car Congress

On-road transportation accounts for approximately 20% of United States energy consumption. The team built on the Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (GREET) model, version 1.8d1, from Argonne National Laboratory. Associated tailpipe emissions alone account for 40?60% —Tessum et al.
