Oil company Shell has joined Exxon-Mobil as one of the big oil giants that knew about the dangers of global warming decades ago, and, like Exxon, subsequently worked to bury the issue. An educational video produced by Shell in 1991, titled Climate of Concern, has resurfaced courtesy of the Dutch climate news website, The Correspondent, that comprehensively outlines the human impact on global warming, the dangers the phenomenon poses, and potential solutions to the problem.
In late October, Exxon Mobil CEO Rex Tillerson announced that his company is backing the concept of a carbon tax, saying that climate change brings real risks, and serious action is required to mitigate them.
“We have long used a proxy cost of carbon… there’s a range depending on the country, depending on the tax that we think would be appropriate,” Tillerson explained at the Oil & Money conference in London. “We’re trying to influence and inform people and business on the choices they make.”
Last fall, an expose on extensive research into what Exxon knew regarding the petroleum industry’s impact on climate change was published, including evidence that they conducted extensive research into the issue in the 1970s and 1980s. Their findings resulted in exhaustive efforts to cover up what they had discovered, and to staunch public debate on the subject.
An investigation that was launched last fall into allegations that petroleum giant Exxon Mobil misled shareholders regarding what it knew about global warming has recently gained a large number of new backers. Attorneys general from 15 states, the District of Columbia and the Virgin Islands have announced their support for the investigation, originally launched by New York Attorney General Eric Schneiderman in November of 2015. Schneiderman is using New York state’s Martin Act to investigate potential fraud that the company’s campaign of climate change denial may have perpetrated.
