Renowned for ancient churches and the tomb of Dante, the 14th-century poet, the city of Ravenna and its environs along Italy’s Adriatic coast are also home to old-line industries like steel and fertilizer. The manufacturing plants are of little interest to the many tourists who help sustain the area’s economy, but these sites employ tens of thousands of people.

The question is: For how long? The factories, like others in Europe, face increasing pressure from regulators to reduce the climate-altering gases that their operations produce. The worry is that rising costs from regulation will force them to close.

“We are very scared about the future of our industries,” said Michele De Pascale, the mayor of Ravenna. “We have to reach this goal to reduce CO2 emissions, but we want to do it without destroying our industries,” he said.

Italy’s energy giant, Eni, which has a large presence in Ravenna, is pushing a plan that the mayor says could help preserve the region’s heavy industries: create an industrial pollution collector.

The company is proposing to construct a network of pipelines to sweep up the carbon dioxide from the sites and store it away in old natural gas reservoirs. It sees this process, known as carbon capture and storage, as a promising new business line that would aid its shift to cleaner activities.
