As the ruler of a country that sits atop 300 billion barrels of oil, Saudi Arabia’s King Abdullah was no fan of proposals to limit the burning of fossil fuels. During most of his reign, the king’s chief envoy to climate talks was a ­global-warming skeptic who boasted of his success at scuttling climate treaties.

But it was in the monarch’s final months that Saudi officials hit upon a more effective way to knock the clean-energy movement off its tracks: cheap gas.

Since Abdullah’s death last week, Saudi officials have recommitted themselves to recent policies that have helped drive oil prices to their lowest levels in a decade. The kingdom’s efforts to manipulate oil markets are wreaking havoc with Saudi Arabia’s chief oil rivals, from Iran and Russia to the tar-sands mines of western Canada. Now energy experts are seeing evidence that the oil bust is helping Saudi Arabia achieve another long-term goal: undermining global efforts to reduce dependence on fossil fuels.

Lower oil prices already have spurred demand for gas-guzzling SUVs and prompted a spike in miles driven by American consumers, new government figures show. Whether intentionally or not, the continued slump in prices could hurt sales of low-emission vehicles in Western countries and cool enthusiasm for renewable energy in the developing world — objectives that Saudi officials have long pursued through other means, analysts say.

“If a period of low prices gets consumers hooked on cheap gas and inefficient cars, that sustains their market,” said Durwood ­Zaelke, an expert on international environmental law and a veteran participant in climate-change negotiations. He described Saudi Arabia’s fight against the zero-carbon movement as “a cage-match in which only one victor will emerge.”

Both West Texas Intermediate (WTI) and Brent crude oil prices have been falling sharply for the past six months, each more than 50 percent below the previous year’s prices.

Saudi officials insist they are not fundamentally opposed to policies that reduce carbon emissions, pointing to increased investment in solar and wind power to meet their country’s energy needs. But analysts say the kingdom’s efforts to engineer a shake-up of global energy markets appears driven by fears about long-term threats to Saudi preeminence as an oil superpower.

The threats include traditional geopolitical rivals, such as Iraq and Iran, and the recent surge in oil production by non-OPEC rivals in North America and Eurasia. But more ominous in the long term, experts say, is the threat of a global shift to renewable energy sources as countries seek to combat climate change. A senior Saudi oil official in 2009 described climate change as “one of the biggest threats we are facing” — not because of warmer temperatures or rising sea levels, but because of the economic losses that would result if countries break their dependence on fossil fuels.

Saudi oil officials have acknowledged that the country stands to benefit from a global shakeout in energy markets. Led by Saudi Arabia, OPEC declined to cut production quotas during its last meeting in November, a move that hastened the fall of oil prices worldwide. Prices rose slightly after the death of King Abdullah last week, then slipped again after Saudi officials pledged to keep the monarch’s oil policies intact.

“You need to allow prices to go as low as possible to see those marginal producers move out of the market,” longtime Saudi oil adviser Mohammad al-Sabban said last week in an interview broadcast by Britain’s BBC. Sabban, who served as the kingdom’s chief climate negotiator before stepping down two years ago, said Saudi Arabia could survive low oil prices better than its rivals because of its production costs and massive cash reserves.

“Saudi Arabia can sustain these low oil prices for at least eight years,” he said.

The outlook for other energy producers is not nearly so rosy. Companies with greater overhead — including oil fields in harsh environments such as the North Sea or Alaska’s North Slope — already have been forced to cut output as prices drop below production costs.

The impact on carbon emissions is inevitable if oil prices remain low, though it may take longer for the effects to be fully realized, energy experts say. Years of research confirms a strong correlation between gasoline prices and consumer choices such as daily driving habits and automobile purchases.

Analysts already are seeing modest shifts in consumer markets. U.S. sales of SUVs grew by 10 percent in the last quarter of 2014 compared with the same period the previous year, and American motorists increased their driving by nearly 3 percent, according to the International Energy Agency.

While sales of electric vehicles have remained steady so far, some drivers and car-fleet managers will think twice about paying for zero-emission vehicles “because the cost savings will be lower,” said Alan Krupnick, co-director of the Center for Energy and Climate Economics at Resources for the Future, a nonprofit Washington research organization.

“Lower oil prices are going to make it more difficult to achieve climate-change goals,” Krupnick said. “In the short term, people will drive more. In the longer term, it can affect investment decisions.

The impact on other kinds of clean-energy technology may not be apparent for months or even years. That’s because infrastructure decisions on solar and wind power are often made far in advance and reflect government policies that are influenced by a multitude of factors in addition to price, analysts say. In the developed world, wildly fluctuating oil prices could actually reinforce commitments to invest in wind and solar, which have relatively low operating costs after the initial capital investments are made, some experts say.

Far less certain, analysts say, is how low oil prices will affect energy choices in the developing world. Rapidly growing economies such as India and China are facing increasingly tougher choices in deciding whether to invest in clean-energy alternatives such as solar and wind or sticking with traditional fossil-fuel sources such as oil, gas and coal in building power plants.

“There is no illusion that this is going to change the dynamics [favoring renewables] for the United States and the Europeans,” said David Goldwyn, president of the Washington consulting group Goldwyn Global Strategies. “But the question is: Does this change the dynamics in Asia?”

At a minimum, Goldwyn said, the price drop allows the Saudis to reassert their influence after years of losing market share to the United States and other suppliers.

“People were saying that OPEC was dead, irrelevant,” Goldwyn said. “Now the Saudis are asserting that they do matter. If they’re not relevant for oil, what are they relevant for?”

Saudi attempts to squeeze out rivals in global energy markets follow years of diplomatic efforts to slow the advance of climate-friendly policies. Saudi officials have repeatedly drawn environmentalists’ ire in recent years with maneuvers intended to block or stall a global agreement on scaling back production of hydrofluorocarbons, or HFCs, a widely used refrigerant that is also a powerful greenhouse gas, with hundreds of times more heat-trapping potency than carbon dioxide. The stated objection to the ban: The Saudis needed assurance that HFC substitutes would work in the kingdom’s hot climate.

At the same time, Saudi officials have taken on the role of spoiler in international negotiations for a climate treaty, joining with other major petroleum producers in demanding politically untenable conditions. One such proposal was for billion-dollar compensation packages for oil exporters to help their economies adjust. “Oil producers are going to face huge liabilities,” explained Saudi diplomat Khalif Abu Leif in suggesting payments for “vulnerable” countries during climate talks in Peru last month.

Western diplomats have scoffed at such demands, but Saudi officials have insisted that the country will not be a passive observer to global efforts to slash fossil-fuel burning. While acknowledging that his country was “in a race with time,” Abu Leif asserted confidently that U.N. goals for quickly shifting to a “zero net-carbon” economy would never be met.

“With a concept like zero emissions and ‘let’s knock fossil fuels out of the picture’ without clear technology diffusion and international cooperation — you’re really not helping the process,” he said.
