In light of the attacks on Tom Steyer from sources linked to the Koch Brothers, InsideClimate News posted a story the other day providing a detailed account of how the Koch brothers made their money. To put it mildly, it's not a pretty picture.
Steyer's turnaround took moral courage, they argued, and asked: What about the Koch brothers? What is their history with global warming emissions?
It turns out the Koch brothers built their first fortune on the particularly dirty form of oil mined in Alberta's tar sands, where they have been major players for 50 years, and remain deeply invested.
The key moment came in 1969, when Charles Koch secured full ownership of a heavy oil refinery in Minnesota that his father had a stake in.
In his 2007 book Charles Koch called that acquisition "one of the most significant events in the evolution of our company." The refinery was a doorway that permitted Koch Industries "to enter chemicals and, more recently, fibers and polymers," he said.
If you want to know more about the Koch brothers and how they built their fortune, InsideClimate News has a helpful timeline with detailed information. It's well worth checking out, just so we all know exactly what we're up against with these folks.
