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

Green Car Congress

The US Department of State (DOS) has released its Draft Supplemental Environmental Impact Statement (SEIS) in response to TransCanada’s May 2012 application for the Keystone XL pipeline that would run from Canada’s oils sands in Alberta to Nebraska. The pipeline would primarily transport crude oil from the WCSB and Bakken regions.

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

Based on visual interpretation of high-resolution (30 m) satellite images, a new study in the journal Global Change Biology: Bioenergy determined that industrial plantations covered over 3.1 Slightly more than half of the GHG emissions for these biofuels in the EPA’s analysis came from land use change.

US rejects Keystone XL pipeline, citing combatting climate change as critical factor; Kerry: arguments pro and con “overstated”

Green Car Congress

The determination by the State Department brings to an end the much delayed, deferred and debated permit process that would have allowed TransCanada to built the fourth phase of its Keystone pipeline system to bring more oil sands crude from Canada to refineries in the US.
