Holko added that while Allstadt had a lengthy career with Mobil he was skeptical whether his conversion to the anti-drilling movement was motivated by a genuine understanding of the science and technology used in drilling.
Allstadt, noting he has never met Tillerson, said he no longer has any connection to Exxon Mobil.
“I don’t have a pension and I no longer have any stock,” he said.
A spokesman for Tillerson told Reuters this week that Tillerson does not object to water from the tower being used to assist in fracking operations. The spokeswoman pointed out Tillerson’s property is adjacent to several oil and gas wells.
In his letter, Allstadt encouraged Tillerson to have ExxonMobil step up its involvement in renewable energy. “I am now much more concerned with the greenhouse gas impacts of fossil fuels in general, and particularly the huge impact of methane emissions from natural gas production and transportation,” Allstadt wrote. “These are global problems that local zoning cannot protect against. Only a major shift toward renewable energy sources can begin to mitigate their catastrophic climate impacts.”
He ended the letter by noting: “Good luck with that fracking water tank. I hope you don’t have to move, and also that you will help a lot of other people stay in the homes they love.”
