Increasingly, industry analysts are also worrying about demand projections for oil and other fossil fuels, not just pending climate laws.
What if China's energy demand falls well short of the industry's lofty expectations? What happens to oil if natural gas displaces it in more markets? Can oil and gas companies continue bankrolling the soaring expenses of both new projects and current production without threatening the quarterly payouts investors have relied on for decades? What happens to all those hard-to-reach reserves if world oil prices sink below break-even levels?
"It's a really different world where you have big mainstream analysts saying that it’s not peak oil supply that we should be concerned about—it's the reverse, peak oil demand," said Craig Mackenzie, head of sustainability at the
Scottish Widows Investment Partnership, which manages $234 billion in assets. The firm owns stock in fossil fuel companies (except coal), and is one of the companies backing the new Ceres initiative.
For instance, in a new report called "
Global Oil Demand Growth—The End is Nigh," Citigroup disputed the broadly held belief that the world's thirst for oil will continue its inexorable rise through to 2030. The study was based on assumptions about fuel efficiency improvements that are already planned for the United States, Europe and China and the steady shift to natural gas-powered commercial vehicles.
Under Citigroup's analysis, Mackenzie said, "You get global oil demand potentially peaking around 2020, which is a very different story than you get from oil industry forecasts."
Coal Is Particularly WorrisomeBut the biggest question for concerned investors is how climate policies will unfold. If governments don't implement tough climate laws, then fossil fuel companies could burn through their reserves as planned providing other factors don't intervene. However, if national or global policies require steep cuts in the use of fossil fuels, they could gut the value of those companies that get stuck with unburnable resources they can't cash in.
The outlook for companies laden with coal is particularly troublesome, analysts say. Mackenzie cited a Bernstein & Co. report that noted that coal demand is falling everywhere except China, and that coal demand there will begin to fall by 2017. New efforts to cut worldwide carbon emissions would accelerate that downward shift, since coal can have three times as much embedded carbon than other fuels.
In the United States, a mix of plummeting demand and environmental restrictions on harmful emissions has already stranded coal deposits that can't be burned. That shift caused the share prices of coal companies to fall by two-thirds over the last two years, Mackenzie said.
Predictions for natural gas are far rosier, at least in the short term, since it is replacing the use of coal and oil in many industries.
"These concerns about climate impacts have been around for awhile," said Logan from Ceres. However, he said, the potential climate costs are starting to resonate more broadly with fossil fuel industry investors and the companies themselves. The theory about stranded carbon assets, he added, "has risen from what was seen as a fringe issue a very short time ago, to now firmly being in the mainstream."
What's made the difference is the magnitude of what's at stake, according to Mackenzie of the Scottish Widows Investment Partnership.
"We're talking about trends that are massively significant to share prices," he said. "We're moving to a space where these issues are just much, much more material than they have been."
The Origins of the DebateToday's debate over the financial impacts of burning fossil fuels recklessly has its roots in
a landmark 2009 climate paper by scientists led by Malte Meinshausen, a climatologist at Germany's Potsdam Institute for Climate Impact. The researchers found that at the current rate of fossil fuel use, dangerous warming—surpassing the two degree Celsius limit—could hit the globe in as few as 11 years.

That got the attention of the international financial community, because the values of the world's energy companies are linked to future earnings from selling oil, gas and coal stockpiles that scientists now suggest might have to remain underground.
