A study issued Tuesday by an energy watchdog group offers important new insights into the fossil fuel industry's extensive early understanding of climate change and the risks it poses.
This time, it's the electric utility sector that's under the microscope.
The detailed study, backed up by reams of archival documents, was issued by the Energy and Policy Institute, an environmental advocacy and research group that favors the use of clean energy over fossil fuels.
Forty years ago, the documents show, industry officials told Congress that the looming problem of climate change might require the world to back away from coal-fired power—something that is only now beginning to happen.
The research presents a distinct echo of an investigation of Exxon's climate record published by InsideClimate News almost two years ago, and casts significant new light on the duration and depth of industry's climate research—and how electric companies that use fossil fuels responded to the emerging science from the 1960's onward.
The 66-page report unearths research documents and testimony published but then largely forgotten decades before the climate crisis emerged as a key public issue.
And in this episode of the nation's climate history, once again, the same industry that foresaw the ultimate end of coal as a main fuel for power generation later supported actions to cast doubt on the science and to stave off policies to address the problem, funding groups that deny the scientific consensus and joining the main industry group that opposed participation in the first climate treaty. To this day, there are few federal limits on emissions of carbon dioxide by utilities, one of the biggest sources of greenhouse gases.
"It's a story with striking parallels to the investigations into ExxonMobil's early knowledge of climate change and later efforts to deceive investors, policymakers and the public on the issue," EPI said.
Asked for comment, a spokesman for the Edison Electric Institute, one of the trade associations scrutinized in the report, said only that the industry has made deep reductions in its emissions of carbon dioxide since 2005.
Dave Anderson, one of the authors, said that the report might "provide fodder" to those such as state attorneys general or private plaintiffs taking legal steps to force the industry to more fully describe the risks of climate change to shareholders, or even to compensate for damages that ensued from emissions.
By 1988, the EPI report said, the Electric Power Research Institute, supported by the industry, acknowledged "a growing consensus in the scientific community that the greenhouse effect is real."
Even so, EPI said, some in the industry joined oil and other industries in the climate-denial front group known as the Global Climate Coalition, which lobbied successfully to get the United States out of the Kyoto Protocol during the George W. Bush administration.
It is striking that specialists in the industry understood the risks of climate change early enough to expand research efforts into the problem substantially in the 1970's, about the same time Exxon launched cutting-edge research on its own.
The new report resurfaces many detailed documents, some of them previously mentioned by InsideClimate in its Exxon reporting, others not widely circulated in recent years.
The 1960's, the earliest years of significant federal government interest of the looming carbon dioxide problem, especially during the presidency of Lyndon B. Johnson, utilities were among the industries contributing to extensive government studies that raised the issue of climate change as an important consideration. Mostly, they recommended diligent research, since there was not yet quantitative evidence or sophisticated models of how continuing use of fossil fuels would impact the climate.
By 1977, the Electric Power Research Institute, funded by the industry, was testifying in Congress that the global warming consequences of greenhouse gases could force a shift away from fossil fuels, especially coal, a message that the group repeated in its house publication that year. (At about that time, the National Academy of Sciences was first warning that climate change, not resource scarcity, was likely to limit the use of fossil fuel in the decades ahead.)
By 1988, the EPRI Journal would run an editorial declaring outright: "There is a growing consensus in the scientific community that the greenhouse effect is real." It described potentially grave impacts, but added that "shifting away from fossil fuel use is a prospect that seems impractical."
