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

Green Car Congress

Comparison of the percent differential for WTW (well-to-wheel) GHGs from gasoline produced from WCSB oil sands using different production processes relative to gasoline produced from reference crudes. Source: FEIS, Appendix V. Click to enlarge. The proposed Project is not likely to impact the amount of crude oil produced from the oil sands.

State Department issues Draft Supplemental Environmental Impact Statement on Keystone XL Pipeline: climate change impacts

Green Car Congress

The DOS SEIS accordingly takes a detailed look at life-cycle greenhouse gas emissions of petroleum products from Western Canadian Sedimentary Basin (WCSB) oil sands crudes compared with reference crudes and the potential impact the pipeline might have on climate change as well as on the future development of the oils sands resource in Canada.

Study finds pollution strengthens thunderclouds, warming the atmosphere

Green Car Congress

Called deep convective clouds, thunderstorm clouds reflect a lot of the sun’s energy back into space, trap heat that rises from the surface, and return evaporated water back to the surface as rain, making them an important part of the climate cycle. Reference: Resources. At the same time, cold air falls, creating a convective cycle.
