BRUSSELS — Facing soaring natural gas prices and a potentially painful winter, European Union officials on Wednesday presented a package of policy suggestions aimed at helping the bloc's 27 member states combat the ongoing energy crisis — while protecting the most vulnerable.

The guidance, some of whose recommendations have already been adopted by several countries, falls short of the sweeping action that some leaders had demanded. However, it represents the most significant step the E.U. has taken to address record-high energy prices that threaten to hold back the bloc’s recovery from the coronavirus pandemic and undermine support for its transition away from fossil fuels.

The European Commission, the E.U.’s executive arm, said member states should focus on protecting low-income households and small businesses from the price spikes. It said countries can do so without running afoul of E.U. law by providing direct aid to vulnerable consumers or companies, temporarily cutting taxes, allowing the deferral of bill payments and implementing a safety net that ensures people will not have their power cut off.

“Everywhere people ask: ‘Can I pay my next bill? How long will it last? What can be done?’ Their concern is understandable and justified,” said E.U. Energy Commissioner Kadri Simson. “Winter is coming.”

“Our answer to what should be done is twofold: First, our immediate priority is to protect Europe’s consumers, especially the most vulnerable,” she said. “Second, we have to make our energy system better-prepared and more resilient so that we don’t have to face a similar situation in the future.”

The commission indicated it would consider a new system of collectively buying and storing natural gas — a joint procurement process that could resemble the way the bloc approached coronavirus vaccines.

Such an approach would allow member states to join forces in buying fuel and managing reserves, giving them more leverage in negotiations with suppliers. But the commission was noncommittal on this front, saying only that it would “explore the possible benefits” of the idea.

“A more integrated European approach could potentially optimize costs and protect against price volatility,” Simson said.

While some countries have called for the bloc to move faster and substantially overhaul gas and electricity markets, the E.U. has limited ability to intervene directly in the energy policies of its member states, and Simson said national governments are best positioned to take action. Officials said that supply is not at immediate risk but that prices would probably remain high through the winter. The issue is likely to dominate a summit of E.U. heads of state in Brussels next week.

The European continent is not alone in the energy crunch. Across the English Channel, Britain is struggling with fuel shortages and panic buying at its gasoline stations, while India is running low on coal and China is rationing electricity.

The European Parliament’s second-largest political group is among those pushing the commission to commit to more-concrete actions, such as temporarily freezing electricity prices at their early 2021 levels. “I don’t see how these vulnerable Europeans will find protection from these high bills with just words from the European Commission,” Dan Nica, a Romanian lawmaker with the Progressive Alliance of Socialists and Democrats, said in a statement.

The global crisis is partly the byproduct of pandemic-induced economic turbulence. When covid-19 shut down the world, energy use plummeted and prices fell. But economies have rebounded rapidly and demand has soared, sending prices skyrocketing. At the same time, an unusually cold European winter last year drained supplies, and weather patterns in the North Sea led to lower-than-expected production from wind turbines.

But the crisis also highlights the E.U.’s reliance on energy imports. Russia is the bloc’s primary supplier of oil, natural gas and solid fossil fuels, such as coal — a relationship that leaves Europe dangerously vulnerable to exploitation by Russian President Vladimir Putin, according to Aura Sabadus, writing for the Atlantic Council think tank.

A group of E.U. lawmakers have said Russia may be limiting gas supply to inflate prices and pressure European regulators to fast-track the approval of its Nord Stream 2 pipeline, which runs from Russia to Germany through the Baltic Sea and has not yet gone into operation.

The European Commission is investigating Russia’s state-owned energy company, Gazprom, amid the market manipulation accusations. In the document it published Wednesday, the E.U. said the St. Petersburg-based gas giant has “fulfilled its long-term contracts” with European customers but “has offered little or no extra capacity to ease pressure on the E.U. gas market.”

Putin hinted last week that Russia would increase supply, and Kremlin officials said Tuesday that Gazprom has begun using its stockpiles to stabilize the market.

The rising prices have also underscored existing and long-running tensions among E.U. leaders.

Premiers such as Hungary’s Viktor Orban, who has a history of aligning himself with Putin, have blamed the increases on the bloc’s wide-ranging policies to combat climate change, saying the E.U. must reconsider its ambitious goals.

Some analysts have also said the E.U. has moved too quickly away from fossil fuels and has not ensured that its members will have an adequate supply of renewable sources in case of an emergency.

But others have argued that the crisis only reinforces the need for initiatives like the European Green Deal, a package of proposals to make the E.U. carbon-neutral by 2050.

“We are not facing an energy price surge because of our climate policy or because renewable energy is expensive,” Simson said Wednesday. “We are facing it because the fossil fuel prices are spiking. We do not yet have enough of that green affordable energy for everyone. We need to speed up the energy transition, not slow it down.”

The E.U. has also come under increased pressure to clarify its position on nuclear energy. France and several other countries want the commission to classify nuclear as a “green investment,” an important definition for compliance with the bloc’s climate goals. But the commission punted the question to a later date.

The European Consumer Organization, an umbrella organization of consumer groups, cheered the commission’s recommendations and urged national governments to implement them.

“We’ve seen staggering increases in energy prices recently,” Monique Goyens, the organization’s director general, said in a statement. “As we head into winter and start to spend more on heating our homes, it’s consumers who are in the eye of the storm, having to pick up the bill for market forces totally beyond their control.”
