Several big oil companies have fallen into unlikely alignment with environmental groups calling for new taxes on air polluters like coal-burning power plants. One key reason: Those taxes are probably good for their natural-gas businesses.visu

Energy giants including Royal Dutch Shell PLC and BP PLC hope a so-called carbon tax--which would force companies to pay for their emissions and likely increase oil producers' costs--also would increase demand for natural gas, an increasingly significant part of their output.

The companies are part of a collection of business interests, environmental activists and economists that have urged negotiators meeting at a U.N. climate-change summit in Paris over the next two weeks to consider potential carbon pricing policies as a tool to curb emissions. Such programs could open new markets in China and elsewhere for gas to displace coal.

Most carbon-tax plans being discussed wouldn't much affect transportation fuels that oil companies already sell, says the Organization for Economic Cooperation and Development. Automobile fuel is already heavily taxed in much of the world, while coal-heavy power production often isn't.

"Coal," BP's chief economist, Spencer Dale, said in an October speech, "is likely to be more affected by future climate policies than either oil or gas."

The embrace of carbon taxes demonstrates how some oil companies now see a business opportunity as efforts to enact climate-change policies gain momentum. While not entirely new, oil companies have become more vocal in their support for carbon taxes in recent years.

Oil companies including BP, Shell and France's Total SA joined forces in recent months to push for action on climate change, calling for taxes to encourage the use of cleaner-burning gas over coal. BP has said switching just 1% of world-wide power production to gas from coal would have an equivalent emissions reduction as increasing renewable-energy generation by 11%. Exxon Mobil Corp. isn't part of the coalition, but in recent years it has expressed support for a carbon tax, provided it is offset by tax reductions elsewhere.

Their support for a carbon tax carries relatively little risk, says Kurt Van Dender, the head of the tax and environment unit for the Organization for Economic Cooperation and Development, a group of first-world countries that includes the U.S. and Western European nations.

Around 80% of carbon emissions in the U.S. and Europe come from power plants and big industrial sources that largely use coal, he said.

"The relative increase [in costs] will be much higher for these non-oil types of energy," he said.

Coal producers say any financial incentives to reduce CO2 emissions should be directed toward the development of carbon capture-and-storage, or CCS, technologies that force emissions into underground reservoirs.

"Market mechanisms, including carbon pricing, should not impose punitive costs but should instead provide revenues that can be directed toward the deployment of low-emission technology, including CCS," said a spokeswoman for the World Coal Association, an advocacy group for coal producers.

Positioning "coal as the villain and gas as the solution" isn't a productive long-term approach to curbing climate change, said Daniel Litvin, managing director of Critical Resource, a London-based resource-extraction consultancy. Shifting to natural gas from coal is "pretty far off the major transformation that's needed," he said. On Wednesday, his group said oil companies should focus more on alternative energy and energy efficiency.

A global carbon tax is unlikely to emerge from the U.N. climate summit, but any international commitment to reducing emissions likely will result in individual countries implementing their own version of pricing carbon.

The pro-carbon-tax talk hasn't taken oil companies out of the sights of environmental groups and policy makers who want to reduce fossil-fuel use. Shell this year faced protests in the U.S. for its exploration of the Arctic offshore Alaska, which environmental groups said could lead to pollution. Shell said it had taken all necessary precautions but pulled out of the project in September when drilling results were disappointing.

In November, the New York attorney general's office confirmed it sent Exxon a subpoena for information on the company's research on and response to climate change going back decades. The request followed stories by InsideClimate News that detailed Exxon's 1970s research into climate change and later support for groups that questioned climate science. Exxon has said it didn't do anything wrong.

Many environmentalists say the companies' support for a carbon price won't be sufficient to prevent global temperatures rising by dangerous amounts in the coming decades.

Greenpeace campaigner Charlie Kronick said he supports raising the cost of fossil fuels, but he says a carbon tax alone isn't enough to curb global warming, and could benefit the companies that sell fossil fuels. It "absolutely will not do what we need to do, which is dramatically reduce fossil fuels," he said.

Some oil companies, particularly in the U.S., remain suspicious of regulation and taxes overall. In a speech in October in London, Exxon Chief Executive Rex Tillerson pointedly noted that the U.S. had curbed emissions with an increase in natural-gas usage for electricity "in the absence of a comprehensive cost-of-carbon policy."

Oil companies also oppose policies that would force a fast switch to more reliance on renewable energy, saying the world's energy needs are so great that fossil fuels will remain a part of the picture for decades.

The carbon-tax push isn't oil companies' first foray into promoting more environmentally friendly energy alternatives. In the 1990s, for instance, Shell and BP invested in solar energy and other renewable sources, but they have scaled back many of those investments, scrapping some altogether. A Shell spokesman said the company is continuing with a "multibillion-dollar" investment in biofuels.

Shell has produced more gas than oil on an annual basis since 2009. BP expects natural gas to make up about 60% of its total production by the end of the decade and nearly 50% of Exxon's production last year was gas.
