Pope Francis told world oil executives Saturday that the transition to less-polluting energy sources "is a challenge of epochal proportions," and warned that satisfying the globe's energy needs "must not destroy civilization."
The Vatican says the two-day conference with oil executives was meant as a follow-up to the pope's encyclical three years ago calling on people to save the planet from the ravages of climate change and other environmental ills.
Participants included the CEOs of Italian oil giant Eni, British Petroleum, Exxon Mobil and Norway's Statoil as well as scientists and managers of major investment funds. Their remarks on the first day of the closed-door conference were not released by the Vatican.
While Francis lauded the oil executives for embedding an assessment of climate change risks into their planning strategies, he also put them on notice for their "continued search for fossil fuel reserves," 2 1/2 years after the Paris climate accord "clearly urged keeping most fossil fuels underground."
"Civilization requires energy, but energy must not destroy civilization," he implored.
Energy experts and those who advocate fighting climate change expressed doubts before the conference that it would amount to anything other than a PR opportunity for the companies to burnish their image without making meaningful changes.
In his remarks, the pope said he hoped the meeting gave participants the chance to "reexamine old assumptions and gain new perspectives."
Francis said that modern society with its "massive movement of information, persons and things requires an immense supply of energy." And still, he said, as many as one billion people still lack electricity.
The pope said meeting the energy needs of everyone on the planet must be done in ways "that avoid creating environmental imbalances, resulting in deterioration and pollution that is gravely harmful to our human family, both now and in the future."
Frances also recalled his own appeal in the "Laudato Si" encyclical for an energy policy "aimed at averting disastrous climate changes that could compromise the well-being and future of the human family, and our common home." That includes transitioning to efficient, clean energy sources.
"This is a challenge of epochal proportions," he said Saturday. "At the same time, it is an immense opportunity to encourage efforts to ensure fuller access to energy by less developed countries ... as well as diversifying energy sources and promoting the sustainable development of renewable forms of energy."
The pope called for a "long-term global strategy to provide energy security," along with "precise commitments" to tackle the challenge of climate change.
He said it was "disturbing and a cause for real concern" that the levels of carbon dioxide emissions and the concentrations of greenhouse gases remain high despite commitments taken in the 2015 Paris accord to fight global warming.
